Trenbolone hexahydrobenzylcarbonate, or trenbolone cyclohexylmethylcarbonate, sold under the brand names Parabolan and Hexabolan, is a synthetic, injected anabolic–androgenic steroid (AAS) of the nandrolone group and an androgen ester – specifically, the C17β hexahydrobenzylcarbonate (cyclohexylmethylcarbonate) ester of trenbolone – which was marketed in France for medical use in humans but has since been discontinued.

It was introduced in France in 1980 and was voluntarily discontinued by its manufacturer in 1997. The drug acts as a long-lasting prodrug of trenbolone when administered via intramuscular injection. It was used clinically at a dosage of one ampoule (76 mg, corresponding to 50 mg trenbolone base) every 10 days.
