Tren Base Injectable 17-beta-Trenbolone Powder Trenbolone Base With High Assay Muscle Growth Steroids CAS 10161-33-8

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

It is these additional modifications of double-bonds at carbon 19 and 11 that grant Trenbolone to be not just resistant to aromatization, but to become completely immune to it and be unable to interact what so ever with the aromatase enzyme. These modifications are also responsible for Trenbolone’s extremely enhanced andrognic strength (its ability to bind at a much greater strength to the androgen receptor) and its ability to remain highly resistant to metabolic breakdown in the body.

The chemical modifications described above result in Trenbolone becoming dramatically more potent of an androgen and an anabolic than its progenitor hormone Nandrolone, or even Testosterone. Testosterone is used as the baseline reference by which all other anabolic steroids are measured against and compared to (much like how the Celsius temperature scale utilizes the boiling and freezing point of water as the base reference for temperature measurement).

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.

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).
