What is Trenbolone Enanthate?
Trenbolone Enanthate (Long-acting 19-nor anabolic-androgenic steroid (injectable)) is a trenbolone enanthate ester — C₂₅H₃₄O₃, MW 382.5. Long-chain ester of trenbolone providing extended release (peak ~3–5 days, active ~10–14 days). 19-nor derivative with ~5× greater AR affinity than testosterone. Does not aromatise. Also activates progesterone receptor (PR).
