Characteristics:
According to many an opinion this drug delivers the best gains, qualitatively speaking, for money. You notice two names on top of this profile, but unfortunately finaject hasn't been made in quite a while now. Since 1987. This is quite a shame. Both Finaplix and finaject are veterinary steroids and were readily and easily available for democratic prices. Finaject was an injectable and provided you could find a sterile source it was quite convenient. Now only finaplix remains as the original source of trenbolone acetate. The Ttokkyo brand trenbol75 surfaces from time to time as well, but its derived from the same material, though qualitatively not as pure. The problem with finaplix as opposed to finaject is that it comes in veterinary implant pellets, and trust me, you don't want to get one of these babies shot in your butt. So it needs to be converted to either a transdermal (often using DMSO) or an injectable. There are kits to achieve both. Trenbolone nasal sprays are gaining popularity as well.

Trenbolone acetate is rather short-acting but well liked because of its great availability and price. The alternative is the limited availability of Parabolan, a longer-acting trenbolone ester made for human use. Unfortunately certain lots only surface from time to time and they never sell cheap. They do act quite a bit longer. Parabolan (trenbolone as hexahydrobencylcarbonate) has the half-life of an enanthate meaning it requires less frequent injections. One of the major problems with finaplix however is that beginners making sterile injectable compounds isn't a wishful thing, and often leads to abscesses and infections.

The fun with Fina is that it causes small, well-maintainable and quality gains. Naturally it won't give you the sort of mass that testosterone or methandrostenolone would give, but it makes up for it by adding only quality mass (no estrogen formation, so no fat and water retention) which is quite easy to keep on your frame. In contradiction to many aromatizing steroids such as testosterone where a large portion of the gained mass is quickly lost again after discontinuation of the product.

It's also a very versatile product that can be used in a lot of different ways. One could easily stack it with testosterone, anadrol or dianabol for mass gains where the actions of trenbolone cause severe strength gains and add some quality to the mass. Since trenbolone was found to be roughly 3 to 4 times as anabolic as most testosterone esters it quite easily boosts strength over short periods of time. It acts well on the androgen receptor with as a result that it can have certain side-effects. Most notably the normal androgenic side-effects such as increased acne and a risk for prostate hypertrophy, definitely increased aggression leading to roid rage in prolonged use of high doses and in some cases an aggravation of an existing hair loss problem.

On the other hand trenbolone just as easily combines with stanozolol or methenolone for purposes of reducing body-fat. Bill Roberts recently claimed that trenbolone doesn't reduce body-fat and that nothing in the literature proves it does. But I beg to differ. Either Mr.Roberts isn't too bright or he doesn't know how to perform a medline search, since after a mere minute of searching I found a study1 that clearly documented the fat-loss aspects of trenbolone acetate. It clearly concluded (even said so in the abstract) that trenbolone does indeed reduce body-fat (as androgens do, we discuss this in our profile of Masteron), but only when not competing with circulating estrogen. This means as a fat-loss agonist, trenbolone is best used late in a cycle and only combined with non-aromatizing steroids since it competes with circulating estradiol. Body-fat percentage when cutting would drop regardless, simply because of the qualitative lean mass gain made while no extra body-fat is deposited.

And finally in doses of 50-100 mg daily, trenbolone acetate can be used just fine by itself and quite favorably. In fact for people starting out, not too concerned with the side-effects and looking solely for a quality increase in lean muscle, small doses of fina (50mg/day injectable) would be very suitable.

The mechanism by which trenbolone mediates skeletal muscle hypertrophy is diversified and not very well understood. On the one hand trenbolone is a very active agonist of the androgen receptor, as illustrated by its increasing strength and aggression at the level it does. While this is a large contributor there is evidence that it mediates muscle growth by another pathway entirely2,3, namely the increasing of satellite cell sensitivity to an increase in IGF-1 (Insulin-Like growth factor 1) and FGF (Fibroblast growth factor). This would result in a much, much greater nutrient uptake and protein synthesis and explain why trenbolone is so much more potent in building lean muscle than other non-aromatizing, AR-mediated steroids like drostanolone and mesterolone.

In fact, in veterinary cycles the androgenic hypertrophy is regarded as the strongest of any steroid, which is why instead of using aromatizing compounds to enhance mass in cattle, they now inject them with products like Revalor-S, which contains trenbolone and estradiol, to make up for the lack of estrogenic mass accrual.

The points one may wish to consider during use of Fina is the low sterility of some home-brewed concoctions along with the already relatively painful injections (high alcohol content). This can lead to multiple problems when it is injected daily. Lumps due to plentiful same-site injections, abscesses and infections caused by faulty filtering and so on. Trenbolone is not particularly toxic though. Liver values are barely elevated while using it. Though there is no evidence or explanation to support this, some users reported a certain kidney-toxicity. Blood in urine and all that. While this was no doubt the result of a fake (Finaject used to be an often faked steroid shortly after its discontinuation) but I figured I'd mention it. Other than that mild androgenic effects such as acne and an increase in hair loss are noted as well.

For those seeking to use trenbolone there are many online sources on how to make injectable, transdermal and intranasal forms if you can get your hands on fina. Some sites even sell conversion kits that make the whole even easier.

Stacking and Use:
Trenbolone is relatively safe steroid all in all. There is some concern about kidney toxicity, but usually exaggerated. The beauty of trenbolone is that its one steroid that has it all : Its highly effective in its own, provides all lean gains which are fairly easy to maintain and isn't very prone to cause side-effects. Finaplix particularly provides you with a cheap source of trenbolone as well. The problem is making the cartridges into a sterile injectable or transdermal.

A transdermal is made quite easily. Option number one is simply to get your hands on some DMSO, mix up a 50/50 mix of DMSO and water, add in the crushed up fina pellets and apply to the skin. The second is to make an alcohol carrier. You can find the necessary products at any local pharmacy and the more you buy, the cheaper it gets. All of it perfectly legal, easy to obtain since pharmacies are supplied 5 times a day and not too expensive. You need ethanol (as pure as it gets, I use SD40) and Isopropyl Myristate (IPM), a mix of isopropyl alcohol and myristic acid. Mix up 70% ethanol and 30% IPM and dissolve 50 mg per ml trenbolone in your solution. Meaning if you had a solution of half a liter (500 ml) you could add in 25 grams of trenbolone. Again, simply apply and let it dry. These methods will give you roughly 25% absorption of trenbolone.

To get the maximum it is recommended that you inject the stuff of course, but that's slightly more complex as you need to get rid of a lot of the crap they put in these cartridges. You will need sterile oil, solvent (lipophillic), 1 empty sterile container, A syringe filter, two syringes and 2 18gauge needles. Start by putting your pellets in your solvent, and let it sit. You want the pellets to become completely undone and dissolved in your fluid. This is imperative. Shake it up real good and then let it sit for 12-48 hours to let all the crap sink to the bottom. Now take one of your syringes and start transferring the fluid into the sterile oil. You can decant as well, but you really don't want any of the crud on the bottom to make it into this solution, so using the syringe and doing it slowly is the best way. Now take your empty sterile container and use a new syringe to transfer the oil. Attach a syringe filter between syringe and needle and slowly put the oil into your container, slowly filtering it. For everytime you repeat this step you need uncouple the filter/needle from the syringe, or else dirt will gather at the wrong side of the filter and get into your solution. In fact, if your container is a vial its advised that you leave the needle in the vial with the filter on it and you just use the syringe to refill and filter. This solution is now fit to be injected. Its still advised to hold the syringe with the trenbolone under some hot streaming water before injecting first though.
One may also want to note that finaplix has decent oral availability as well. In fact, because of the acetate ester its transdermal availability is less than it would be for a pure steroid, so actually its oral potential is greater than its transdermal potential. When taking oral fina, to account for the difference in availability between this and injectable, one would have to consume 240 mg ( 3 times 4 pellets) every day for 6-8 weeks. But it does work and it saves you the time and cost of making a transdermal.

Nasal sprays and sublingual forms are also popular, and while they too have some minor success, they are the worst way to go. It's a steroid, and with the added ester its even more lipophillic. Since the mucous membranes in the mouth and nose only let hydrophilic substances through, the rate of absorption is extremely limited. Usually to achieve this cyclodextrins are used, sugars that are lipophillic on the inside and can hold a steroid inside, but are hydrophilic on the outside, making the whole absorbable through these channels. But since fina does not have this and most of us do not possess the skills to make cyclodextrin complexes in our own kitchens, this is not a path one should consider.

There is little or no need to stack secondary drugs with fina. It does not aromatize. There is some concern as to fina being progestagenic, so you should you opt to stack it with an aromatizable compound it may worsen potential gynocomastia so adding winstrol or Nolvadex, or even both to such a stack may be wise. But in itself or in a non-aromatizing stack this is not necessary. The use for post-cycle estrogen antagonists is limited as well, so Nolva or clomid to boost natural test will have little use. It is a very strong androgen receptor agonist however, so perhaps using some HCG after a cycle may help you retain more gains and prevent testicular shrinkage, but since HCG does increase estrogen that does reinstate the use of Nolvadex or clomid as well.

Fina FAQ
Written By capinatl



KITMAKERS
The standard conversion potency kits will yield is 75mg trenbolone per ml; however, more and more kitmakers are going to a 100mg/ml yield. Most kitmakers post ?magic dissolving solution? on their sites as part of their kit which is actually benzyl alcohol, commonly referred to as ?BA?. Just about any kitmaker you find on the Internet is probably legit as I?ve yet to hear of any scamming kitmaker. Most people, including myself, have a favorite kitmaker due to service and reputation in the bodybuilding community. I?ve used 5 different kitmakers kits and have achieved cycle results with all kits.

A few experienced trenbolone conversion users like to make their own kits by purchasing all that is needed from Internet suppliers, and even kitmakers. This is certainly not cheaper or more user friendly, but I think desirable because some trenbolone users develop a very personal relationship with their conversion product. I always suggest buying a kit as it?s the easiest, cheapest and safest way to suspend your trenbolone. There is a lot more room for error in your conversion if you assemble the kit yourself. IMO, if you haven?t done four or five conversions there is no advantage in producing the kit yourself.

HOMEBREW VS. PRE-MADE
When trenbolone is suspended by yourself at home you can be assured of two things; potency and sterility. When you purchase pre-made trenbolone from an underground lab (UG) you cannot be guaranteed of either of these issues. Additionally, the price fro pre-made trenbolone can be outrageous ? I?ve seen prices from $8 per ml to $14 per ml. Conversion with a kit and Finaplix will const about $2.65 per ml, you will NOT find trenbolone pre-made from a source for less than $5 per ml.

PELLETS VS. POWDER
The most common conversion method involves dissolving Finaplix brand pellets, suspending the trenbolone acetate in oil, separating the methylcellulose and filtering the suspended product. With trenbolone acetate in powder form we have the luxury of not dealing with the methylcellulose and simply dissolving and suspending trenbolone in solvents and oil. This method is obviously more desirable and becoming more popular. One security in using Finaplix pellets is you know you are receiving true trenbolone. If you have access to powder be sure you know your source. Whether you use pellets or powder I promise you will benefit from trenbolone results.

CLOUDY FINA, THE COFFEE FILTER & BAKING
Cloudy fina is completely fine, just a cosmetic issue; fina legend basskiller has said that if you let the suspended trenbolone sit for a day before filtering with a Whatman filter and/or coffee filter your conversion will come out clearer. Many homebrewers ask if using the coffee filter is necessary ? it is not. I utilize the coffee filter after I?ve filtered all I can through the Whatman. I pour the leftover sludge into a coffee filter and squeeze out all I can with my fingers and then filter that through the Whatman filter. This can yield another 4 or 5 mls in your conversion. Most coffee filter users pour their whole conversion through the filter which takes all night, and then filters through the Whatman filter for a very clear conversion. I bake my fina for 30 minutes at 250 degrees. Some suggest baking for 45 minutes, and still others suggest baking for 15 minutes, cooling, and repeating two more times. One thing is universal, and that is the baking temperature of 250 degrees. It is brutally important that you obtain an oven thermometer to calibrate your oven to 250 degrees. Rarely have I used an oven that was accurate. In order to destroy your trenbolone you will have to bake it at 400 degrees according to most fina fanatics, so don?t worry if you are a few degrees too high.

CONVERSION MATHEMATICS
Each Finaplix cartridge contains 2000mg (or 2 grams) or trenbolone acetate, so you would need 2 cartridges for a ?4g? kit conversion. The following recipe is intended for a 4g kit: 8ml BA, 42ml oil, and 4000mg (4 grams) of Finaplix pellets. This will yield an end product of 75mg/ml which is the standard conversion. Add your volumes of oil+pellets+BA and divide that number into 4000 for a 4gram kit conversion. 4grams of fina is approximately equal to 4mls.

8mlBA+4gTREN+42ml oil divided into 4000 = 74.07mg/ml.

CONVERSION VARIATIONS
Now, most homebrewers will say that the BA will NOT fully dissolve more than the recommended amount of trenbolone pellets than comes in your kit. For instance, if you use two 2g carts in your 2 g kit you really won't double your potency to 200mg/ml if your kit is designed for 100mg/ml. They will tell you you've wasted a lot of fina. However, I've not seen any tests done on this method of increased potency conversion - so until then I'm somewhat a skeptic. Animal, who is a respected chemist, of sorts, has also said the same thing (that extra carts are a waste). The most trusted method (myself included) of increasing potency strength is to leave out some oil, thus increasing trenbolone ratio to total volume. The biggest negative is that the injections may cause more soreness as the BA ratio is higher than desired by most users. The other problem is that there is skepticism as to whether or not the lower volume of oil will suspend the trenbolone. Once again, I think the jury is out unless someone runs tests.

I don't have the time or care to invest the money to have my conversions tested for potency, so all I have to go by is my experience with physical results and sides while on fina to determine my likely yield potencies. The last kit I got I modified to reduce pain as I am very sensitive to intramuscular fina shots. I've lowered the amounts of BA and added Benzyl Benzoate (BB) as the BB is reputed to help in post injection soreness. The BB will also dissolve and help sterilize the converted product, but allegedly to a lesser degree than BA (of dissolving power especially). This was my last conversion recipe:

2mlBA+4mlBB+4gTREN+29ml oil divided into 4000 = 102.5mg/ml.

This batch was painless, and according to my results was probably under the calculated potency strength of 102.5. I believe this is because I was in a hurry to dissolve and only swirled it for about one hour, and didn't use heat as an aid.

This is my latest attempt at a high potency conversion:

2mlBA+6mlBB+6gTREN+26ml oil divided into 6000 = 150mg/ml

One key thing I've chosen to do differently is to let it dissolve for about three days. I believe that the trenbolone had dissolved nicely, but then I am going solely on visual comparisons to other successful batches I've converted. I also utilized heat just before I completed the conversion as an extra measure. I?ve tested the conversion and could taste the fina even when mixed with testosterone, but until I cycle this conversion alone I can?t comment on the potency accuracy.

DOSAGES
On my first fina cycle I started with testosterone and 75mg trenbolone EOD and exploded in strength, vascularity and hardness. After a few more cycles with fina and experimenting with dosages ranging from 75mg EOD to 112.5mg ED I have concluded for myself that 150mg EOD is all I desire. At 75mg EOD I receive some results, but nothing outstanding. At 150mg EOD I gain in size, strength, vascularity and hardness ? however ? at this dosage I also receive negative side effects like shoulder and lower back cramping, aggression, heartburn, sleeplessness and night sweats. For me, when I begin to get negative side effects I also begin to get positive sides as well. At higher dosages like 112.5mg ED my side effects become unbearable. The muscle cramping pain becomes so intolerable that I often have to stop my workouts, quick in the middle of squat routines, avoid deadlifts, and even totally skip shoulder days. I?ve come to the conclusion that trenbolone dosage is a unique balance of sides vs. results. Once the sides prevent me from achieving my workout goals or force me to modify my routine drastically, it?s time to cut back.

I have a good friend who included trenbolone in his second cycle at 100mg EOD with testosterone and told me he wanted to go to 100mg ED. To this day I still regret replying with a simple, ?O.K.? as his side effects went through the roof. His aggression and attitude changed so much that his mother said to her normally laid back son, ?What happened to my son? I don?t even know you anymore!? He said he couldn?t control himself around his family and girlfriend and unfortunately both relationships dissolved before his cycle completion. Now there are a few on the boards who have done 150mg ED, but all I?ve been in direct contact with have said those high doses have left them with a sour taste for trenbolone. My friend won?t even consider using trenbolone again.

CYCLE DURATION
I?ve done fina for 8 week cycles and even as long as 20 weeks. Post-cycle recovery has not been an issue for me at either duration. Kendahl69 has some lengthy experience with a propionate and fina cycle and I?ve not heard a negative word about fina from him either. As with any AAS, cycle duration decisions have more to do with post-cycle recovery experience and stats than any other factor.

A great cycle might look like this:

Wk 1-4 Dianabol 30mg ED
Wk 1-6 Testosterone Enanthate 500mg wk
Wk 1-8 Trenbolone Acetate 75mg EOD

A next level cycle might look like this:

Wk 1-4 Dianabol 30mg ED
Wk 1-8 Testosterone Enanthate 750mg wk
Wk 1-10 Trenbolone Acetate 150mg EOD
Wk 1-13 Arimidex .25mg EOD

My favorite fina cycle:

Wk 1-4 Anadrol 50mg ED
Wk 1-10 Testosterone Enanthate 250mg EOD (875wk)
Wk 1-12 Trenbolone Acetate 150mg EOD
Wk 1-15 Arimidex .50mg EOD
Wk 1-12 Bromocriptine 1.25mg BID
(Normally I've started and ended this cycle with Prop, but for simplicities sake I've posted it as is.)

CLOMID POST CYCLE
Day 1 - 300mgs
Day 2 - 200mgs
Days 3-14 - 100mg x 12 days
Days 15-21 - 50mgs x 7 days

NEGATIVE SIDE EFFECTS
As with any androgenic anabolic steroid (AAS) side effects include acne, hairloss, high blood pressure, shutdown of endogenous testosterone production and more uniquely; sleeplessness, night sweats, aggression, and shoulder and/or lower back muscle pain. I am one that is very prone to male pattern baldness and have had not lost one hair while on any cycle, including trenbolone. For heartburn I find a jar of Tums will get me through the cycle. I?ve tried Melatonin, a natural sleep aid, with moderate success. The most uncomfortable side effect I get is the shoulder and lower back muscle pain. Many refer to this as a cramp, but it?s more of an endless burn. Drinking 1.5 gallons of water per day has helped me moderately. BillyGman has suggested to many to utilize 500mg of Magnesium bi-daily (BID) and avoid the urban legend of Potassium to reduce muscle cramping. There are quite a few board members who have found Magnesium helpful. I?ve tried the Magnesium BID with moderate success.

FINA COUGH
Many fina users experience the dreaded fina cough eventually. I do believe some are more prone to the cough than others. G-S has done 400 fina injections with only one fina cough experience. I get the cough on almost every inject. There is a lot of speculation as to the catalyst of the fina cough and equal speculation to the validity of each argument. Many people say it?s the solvent, benzyl alcohol, but because ?BA? is used in numerous other injectables as a solvent with no symptomatic cough I doubt this theory. I find it more likely that it is an issue directly related to trenbolone acetate, or possibly as has also been suggested on the boards by Hugh, a combination of the solvent and trenbolone. One preventative measure to fina cough I?ve found to be successful is to slow down the injection as soon as I get the ?alcohol? taste in my mouth; pause and continue the injection and I can avoid the cough entirely. The most fail-proof preventative action is to mix the trenbolone with testosterone/equipoise or another injectable. Most often my fina/test cycles consist of 150mg EOD fina and 875mg test wk, so mixing 1.5mls trenbolone and 1ml of test enanthate EOD is not only a powerful cycle, but one that maintains consistent blood levels with no fina cough at all.

FINA DICK
Unless you are a monk in the Himalayas you are probably concerned with maintaining your erectile function at maximum capacity. Like deca (deca dick), trenbolone is a powerful androgenic anabolic steroid and will shut down your HPTA (hypothalamic-pituitary-testicular-axis) with authority. Most users that do the mistaken fina only cycle find their erectile function ceases around week 5 or 6 of their cycle. There is a small minority of fina only cyclers that claim they actually have a sex drive increase while on fina, but I promise you this is a minority. One board member I?ve known, NeverDie, experienced an additional emotional rollercoaster he wouldn?t wish on his worst enemy. Stacking testosterone with trenbolone will prevent any erectile dysfunction, even at 250mg per week, but for better cycle results 500mg per week is highly suggested. Most importantly, the synergistic effect of combining testosterone with trenbolone will yield substantial results in your cycle.

FINA, DECA & BROMOCRIPTINE
Because both trenbolone and deca durabolin increase prolactin levels they are not suggested to stack together. Estrogen related side effects are considerably easier to combat than progesterone related side effects. There are a few users who stack the two together, and even one underground lab that makes a fina & deca blend as one of their premier products - but you won?t see me test any. Bromocriptine is prescribed to Parkinson Disease patients and is an affordable prolactin blocker (Dostinex is another). A lot of fina users take bromocriptine at 1.25mg BID to combat high prolactin levels, and is often said to strictly follow that dosage as any more than that reduces IGF-1 levels, but I?ve seen no study confirming this statement. From what I?ve learned I don?t believe bromocriptine is even necessary for doses of 75mg ED and lower. If you are one of the rare users that experience bloating on fina then you will likely find bromocriptine beneficial, but probably not necessary to block prolactin levels. There is a lot of talk on the boards that gynocomastia caused by high progesterone levels cannot be combated with nolvadex, but I don?t believe this to be accurate as estrogen must be present in order to induce gynocomastia. Delving into these subjects further would require another article.

TYPICAL TRENBOLONE CYCLE RESULTS
Any experienced AS user knows it is impossible to predict someone?s anticipated results from any steroid cycle, let alone trenbolone. Often trenbolone is stacked with testosterone and an oral to kickstart the cycle and many will say a cycle as such can be a bulker or a cutter depending on diet. Personally I find I get true ?quality gains? with trenbolone; meaning for the most part what I get on cycle I pretty much keep. Usually I even find my strength 6 weeks post cycle is what it was during my cycle peak. A lot of users simply blow up on a fina/test cycle. Certainly strength, vascularity and hardness are common to all who use fina, and should be expected ? but as far a weight gain goes ? this cannot be answered.

FOR THE NEWBIE?
I believe most will disagree with me here, but I don?t think I made any great mistake including trenbolone in my first cycle. I studied and researched trenbolone and concluded that the benefit vs. side effect ratio was ideal, even if trenbolone was the most androgenic steroid available. I was aware that trenbolone had caused female fry fish to change gender and was only allowed to be used in cattle just prior to slaughter, but stacked with test ? it was a hard to beat ?bang for buck? cycle, and I still feel this way. If you are a first time user and decide to go over 75mg EOD - that?s your own decision ? and not one recommended by most fina users. Be careful and watch your sides. Just like any other AAS, this is not a game so be safe.

The many faces (names) of Tren: ENDING THE CONFUSION
By BASK8KACE on AR.

I have been reading about Tren and have found wide spread confusion about it mainly because when one writes "Tren," s/he could be referring to at least 5 different compounds:

1. Trenbolone Acetate--injectable version (Finaject and Finajet)
2. Trenbolone Acetate--pellet form (Finaplix)
3. Trenbolone Cyclohexylmethylcarbonate (called Parabolan by Bill Roberts)
4. Trenbolone Hexahydrobencylcarbonate (called Parabolan on this board and several others)
5. Trenbolone Enanthate

The many names of tren have confused many people. I've seen VETs and MODs and MEMBERs of several boards (not just this one) equate one tren compound with another, not knowing that one is actually not equivalent to the other. One common mistake I see is calling Trenbolone Hexahydrobencylcarbonate "Tren Enanthate." They are similar, but not the same (see below). I also have seen people refer to Tren Acetate as Parabolan--wrong!

So, let's clear this up.

The following is a brief summary of the main differences of each that I have created in order to clear up my own confusion on tren and hopefully help others here in the process. It is not meant to provide a detailed description of Tren activity in the body.

1. Trenbolone Acetate--injectable version (Finaject and Finajet)
This is correctly referred to as "Fina." Finaject is the acetate form of trenbolone. It was produced in a short acting ester (acetate), so its effect lasts only a short time and frequent administration is necessary. Finaject was an injectable steroid of veterinary medicine, which was extremely popular in bodybuilding and powerlifting during the 1980's. The injectible Trenbolone Acetate called Finaject is no longer produced.

(Refer to the end of this post for a discussion of Esters)

2. Trenbolone Acetate--pellet form (Finaplix)
Finaplix was a veterinary cattle implant, which contained the potent androgenic steroid Trenbolone Acetate. Once Finaject and Finajet were nolonger manufactured, bodybuilders began using Finaplix to make topical or injectible versions of Trenbolone Acetate.

Today, cattle implants have become designer products with varied doses and combinations of estrogenic and/or androgenic (trenbolone) agents. So, the process of converting cattle implants to useful versions of trenbolone acetate has become more dificult since one must separate the trenbolone from the other additives present in the cattle implants before using it.

3. Trenbolone Cyclohexylmethylcarbonate (called Parabolan by Bill Roberts)
Parabolan contains a much different ester than Finaject and Finajet, called Trenbolone Cyclohexylmethylcarbonate. This ester extends the activity of trenbolone for more than two weeks, a more suitable design for human use.

The amount of trenbolone in 76 mg of Trenbolone Cyclohexylmethylcarbonate is equivalent to the amount of trenbolone in only 58 mg of Trenbolone Acetate. The acetate is a little more potent, more effective per milligram, because the acetate ester is lighter than the cyclohexylmethylcarbonate ester; therefore a higher percentage of the weight of Trenbolone Acetate is trenbolone. A similar comparison also can be made with the other long lasting esters of trenbolone: enanthate and hexahydrobenzylcarbonate.

The muscle building properties of Trenbolone Cyclohexylmethylcarbonate are the same as Trenbolone Acetate (Finaject or Finajet) except for the longer half-life.

Although it is very similar, this compound is NOT the same as Trenbolone Enanthate. The only difference in these compounds is the esters (see ester definitions below), which all act almost identically (long lasting esters).

4. Trenbolone Hexahydrobenzylcarbonate (called Parabolan on this board and some others)
NOTE: At the time of this post this compound name was spelled wrong (hexahydrobencylcarbonate) in the steroid profiles. The correct spelling is listed above.
Trenbolone Hexahydrobenzylcarbonate and Trenbolone Cyclohexylmethylcarbonate are exatly the same substances. Hexahydrobenzylcarbonate ester is just another name for cyclohexylmethylcarbonate ester.

5. Trenbolone Enanthate
Although it is very similar, this compound is NOT the same as Trenbolone Cyclohexylmethylcarbonate (Trenbolone Hexahydrobenzylcarbonate). The only difference in these compounds is the esters (see ester definitions below).


THE DIFFERNCE BETWEEN THE ESTERS

The most important difference between the esters is wheter it is a short acting ester or a long lasting ester. The next most important difference is the weight of the ester. As mentioned under the Trenbolone Cyclohexylmethylcarbonate section (above), the relative potency of each ester of trenbolone is parially dependent on the weight of its ester.

The main difference between different esters is simply the number of carbon atoms in the ester. Propionate has three carbons, acetate has two, isobutyrate has four, enanthate has seven, cypionate has eight, and decanoate has ten. More unusual esters, such as cyclohexylmethylcarbonate (used in Parabolan) has eight carbons and one more oxygen than the above esters making it the heaviest.

Therefore, the esters of trenbolone in order of potency when compared miligram to miligram (from most potent to least):
1. Tren Acetate
2. Tren Enanthate
3. Tren Cyclohexylmethylcarbonate (Tren Hexahydrobenzylcarbonate)

The differences in potency caused by the esters are negligible. So, you should base your choice of Tren on how frequently you plan to inject, how much you trust your supplier, and how much you trust the brand of tren you purchase.

If you are concerned about the possible side effects of tren, and don't mind frequent injections, then consider using Trenbolone Acetate. If bad side effects manifest, Tren Acetate will quickly leave your body after the last injection due to the short acting ester (acetate); and your body will be able to begin to recover quickly. On the contrary, your recovery from bad side effects won't begin until 2 weeks after the last injection of a long lasting ester of tren because a long lasting ester of tren will stay active in your body for more than two weeks after your last injection--continuing to contribute to the bad side effects.
