What is Trenbolone Hexahydrobenzylcarbonate?
Trenbolone Hexahydrobenzylcarbonate (Parabolan — long-acting 19-nor anabolic-androgenic steroid (injectable)) is the cyclohexylmethylcarbonate ester of trenbolone — C₂₆H₃₄O₄, MW 410.5. The only trenbolone ester approved for human clinical use (French Parabolan, 1980–1997). Longest-acting trenbolone ester (peak ~4–7 days, active ~14 days). ~5× greater AR affinity than testosterone. Does not aromatise. Activates progesterone receptor (PR).
