The drug Trenbolone is, without a doubt, the most powerful injectable anabolic steroid used by Steroid.com members to gain muscle. However the full properties of the drug are not always fully understood. This profile will separate fact from fiction and help steroid.com members decide if Trenbolone is right for them. Trenbolone is similar to the highly popular steroid Nandrolone, in that they are both 19-nor steroids, meaning that a testosterone molecule has been altered at the 19th position to give us a new compound. Unlike Nandrolone however Trenbolone is an excellent mass and hardening drug with the majority of gains being muscle fiber, with minimal water retention (1) It has an unbelievable anabolic (muscle building) score of 500. When you compare that to Testosterone, which itself is a powerful mass builder, and has an anabolic score of 100 you can begin to fathom the muscle building potential of Trenbolone. What makes Trenbolone so anabolic? Numerous factors come into play. Trenbolone greatly increases the level of the extremely anabolic hormone IGF-1 within muscle tissue (2). And, its worth noting that not only does it increase the levels of IGF-1 in muscle over two fold, it also causes muscle satellite cells (cells that repair damaged muscle) to be more sensitive to IGF-1 and other growth factors(3). The amount of DNA per muscle cell may also be significantly increased (3). Trenbolone also has a very strong binding affinity to the androgen receptor (A.R), binding much more strongly than testosterone (4). This is important, because the stronger a steroid binds to the androgen receptor the better that steroid works at activating A.R dependent mechanisms of muscle growth. There is also strong supporting evidence that compounds which bind very tightly to the androgen receptor also aid in fat loss. Think as the receptors as locks and androgen's as different keys, with some keys (androgen's) opening (binding) the locks (receptors) much better than others. This is not to say that AR-binding is the final word on a steroids effectiveness. Anadrol doesnt have any measurable binding to the AR& and we all know how potent Anadrol is for mass-building. Trenbolone increases nitrogen retention in muscle tissue (5). This is of note because nitrogen retention is a strong indicator of how anabolic a substance is. However, it's incredible mass building effects do not end there. Trenbolone has the ability to bind with the receptors of the anti-anabolic (muscle destroying) glucocorticoid hormones (6). This may also has the effect of inhibiting the catabolic (muscle destroying) hormone cortisol (7).
