Trenbolone Acetate 100 mg is a highly potent synthetic anabolic-androgenic steroid (AAS) primarily used in veterinary medicine to increase muscle growth, feed efficiency, and appetite in livestock. While never approved for human medical use, it is used illegally in bodybuilding and athletics for rapid muscle mass gains, strength increases, and fat loss, particularly during cutting cycles due to its lack of estrogenic water retention.

The drug is commonly used in doping within bodybuilding, even though this use is illegal. If intended to assist in bodybuilding, the drug is taken as part of a steroid stack of other anabolic steroids, usually with a potent androgen like testosterone as the 'base' of the stack.
