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.^[1]

It was introduced in France in 1980 and was voluntarily discontinued by its manufacturer in 1997.^[1]^[2] The drug acts as a long-lasting prodrug of trenbolone when administered via intramuscular injection.^[1] It was used clinically at a dosage of one ampoule (76 mg, corresponding to 50 mg trenbolone base) every 10 days.^[1]
