What is Tren Ace?
Trenbolone Acetate (Tren Ace) is a short-ester 19-nortestosterone derivative and one of the most potent anabolic-androgenic steroids. Binds AR with ~3× the affinity of testosterone; does not aromatise but has significant progestogenic activity. The acetate ester provides rapid onset (Cmax ~24–48h) with short active duration (~3–4 days). Widely used AAS pharmacology reference compound and high-affinity AR ligand for research. Research use only.
Research Applications
