Trenbolone Acetate

Trenbolone acetate is a popular ester pro-drug of trenbolone, a synthetic anabolic steroid that’s estimated to be three to five times more potent than testosterone at the androgen receptor. Since the body does not metabolize trenbolone to dihydrotestosterone (DHT) like other anabolic steroids (e.g. testosterone) it is an appealing performance-enhancing drug (PED) in bodybuilding subculture.

However, using trenbolone acetate to build lean muscle mass and increase strength still carries a high risk of side effects. Adverse reactions are all but assured on a trenbolone cycle due to the relatively large doses prescribed by “steroid gurus” and “bodybuilding coaches” on Internet forums.

But the positive effects of anabolic steroid use are irrefutable, and trenbolone (acetate and enanthate) remains one of the most powerful performance-enhancing drugs for muscle growth. What’s interesting about trenbolone is that it’s classified as a selective-androgen receptor modulator (SARM), albeit steroidal, due to its tissue-specific actions and lack of 5-alpha reductase (5-AR) activity.

This guide will quickly bring you up to speed on tren use, how it increases lean muscle tissue, and the side effects you should be aware of before taking anabolic agents.
