Parabolan® is the former French brand name for trenbolone hexahydrobenzylcarbonate, a rarely seen injectable ester of the anabolic steroid trenbolone. Negma in France produced Parabolan until its voluntary discontinuance in 1997. For some time after, there was no real Parabolan preparation to be found on the black market (although to this day you can still find counterfeits of the former French product). That, however, is no longer the case, and this steroid is indeed being sold again through other manufacturers. You may associate the base steroid in this product, trenbolone, with the long deceased Finajet. Finaject was a veterinary steroid that was popular in the United States during the 1980's, which contained trenbolone acetate. This is a much faster acting form of trenbolone than we have present in Parabolan, but otherwise they are the same (see: trenbolone acetate). Parabolan contains the long acting ester hexahydrobenzylcarbonate instead, which extends the activity of the drug for more than two weeks.This form has always been thought of as more suitable design for human use, due to the need for less frequent injections. Original French Parabolan was packaged only in ampules of 1.5mL, one ampule per a box. Each ampule contained 76mg of trenbolone hexahydrobenzylcarbonate, which is equivalent to 50mg of trenbolone base (French drugs commonly make this calculation). Since it is no longer available, however, it is pointed out for reasons of interest only.
Trenbolone is a very potent androgen with strong anabolic activity. It is well suited for the rapid buildup of strength and muscle mass, usually providing the user exceptional results in a relatively short time period.The anabolic effect of this drug is often compared to popular bulking agents such as testosterone or Dianabol, with one very important difference.Trenbolone does not convert to estrogen.This is indeed a very unique compound since mass drugs, almost as a rule, will aromatize (or cause other estrogen related troubles) heavily. When we think of taking milder (regarding estrogen) steroids we usually expect much weaker muscle growth, but not so with Parabolan. Here we do not have to worry about estrogen related side effects, yet still have an extremely potent mass/strength drug. There is no noticeable water retention, so the mass gained during a cycle of Parabolan will be very hard and defined (providing fat levels are low enough). Gynecomastia is also not much of a concern, so there shouldn't be any need to addition an anti-estrogen if trenbolone is the only steroid adminis.
The high androgen level resulting from this steroid, in the absence is excess estrogen, can also accelerate the burning of body fat.The result should be a much tighter physique, hopefully without the need for extreme dieting. Parabolan can therefore help bring about an incredibly hard, ripped physique and is an ideal product for competitive bodybuilders. This is of course no secret, and when available on the market, Parabolan was the most sought after contest preparation drug. Now this it is no longer produced, acceptable substitutes for this purpose include of course veterinary trenbolone acetate preparations, as well as Halotestin®, Proviron® and Masteron.
Trenbolone is notably more potent than testosterone, and has an effect that is as much as three times as strong on a milligram for milligram basis. Likewise we can expect to see some level of androgenic side effects with use of this compound. Oily skin, aggressive behavior, acne and hair loss are therefore not uncommon during a cycle with this steroid.The androgenic nature of this drug of course makes it a very risky item for women to use, the chance for virilization symptoms extremely high with such a potent androgen. And since the hexahydrobenzylcarbonate ester will extend the activity of this drug for weeks, blood levels can be very difficult to control. Since many of the masculinizing side effects associated with steroid use can be permanent, women considering the use of this compound should take extreme caution. It can be weeks before blood levels decline should a problem become evident.
Trenbolone is also much more potent than testosterone at suppressing endogenous androgen production. This makes clear the fact that estrogen is not the only culprit with negative feedback inhibition, as here there is no buildup of this hormone to report here.There is, however, some activity as a progestin inherent in this compound, as trenbolone is a 19-nortestosterone (nandrolone) derivative (a trait characteristic of these compounds). However, it seems likely that much of its suppressive nature still stems from its powerful androgen action. With the strong impact trenbolone has on endogenous testosterone, of course the use of a stimulating drug such as HCG and/or Clomid®/Nolvadex® is recommended when concluding steroid therapy (a combination is preferred). Without their use it may take a prolonged period of time for the hormonal balance to resume, as the testes may at first not be able to normally respond to the resumed output of endogenous gonadotropins due to an atrophied state.         
Those who have used Parabolan regularly would often claim it to be indispensable. A weekly dosage of 3 ampules (228mg) was the most popular range when running a cycle, however, many did find it highly effective in lesser amounts. Although a weekly administration schedule would prove sufficient, athletes usually injected a single ampule per application, the total amount spread evenly throughout the week. While Parabolan is quite potent when used alone, it was generally combined with other steroids for an even greater effect. Leading up to a show one could successfully add a non-aromatizing anabolic such as Winstrol® or Primobolan®. Such combinations will elicit a greater level density and hardness to the build, often proving dramatic for a stage appearance. We could also look for bulk with this drug, and addition stronger compounds like Dianabol or Testosterone. While the mass gain would be quite formidable with such a stack, some level of water retention would probably also accompany it. Moderately effective anabolics such Deca-Durabolin® or Equipoise® would be somewhat of a halfway point, providing extra strength and mass but without the same level of water bloat we see with more readily aromatized steroids.

The main problem with Parabolan historically was that it had always been extremely difficult to obtain, even when the original brand was still being manufactured in France years ago. The demand for this drug was always much greater than the supply, leading to many counterfeits over the years. Some fakes of the old French drug were of such superb accuracy that the untrained eye would miss the details every time. However, too many years have past to hope you will ever see even a single old ampule of this brand on the black market. Some of those good-looking counterfeits are still being made today. Don't be fooled.
