Trenbolone Enanthate powder is a long-ester variant of the hormone Trenbolone. Trenbolone is a 19-nor anabolic steroid that is a derivative of Nandrolone (the basic hormone in Deca-Durabolin). Trenbolone is classified as a progestin due to the lack of a 19th carbon on the steroid structure, which makes it a 19-nor molecule. It introduces two double-bonds between carbons 11 and 9, and it is this chemical modification that effectively makes Trenbolone completely immune to aromatization (conversion into Estrogen) by the aromatase enzyme, as well as increasing the strength with which Trenbolone binds to the androgen receptor. That is, Trenbolone has no estrogenic side effects on its own and is an exceptionally effective and powerful anabolic steroid with a 500:500 anabolic: androgenic ratio. This is amazing when compared to Testosterone, which has an anabolic: androgenic ratio of 100:100. As a result, we can understand how and why Trenbolone is five times stronger than Testosterone. Its molecular alterations also give it a higher resistance to metabolism in the body, letting it maximize its anabolic powers in muscle tissue even more. Finally, Trenbolone Enanthate has the enanthate ester, which is attached to the 17-beta hydroxyl group on the steroid molecule. As previously stated, this decreases the release rate and increases Trenbolone’s half-life in the body to around 7 – 10 days.
