Chemical Identity

Trenbolone Hexahydrobenzylcarbonate is a synthetic derivative of Nandrolone, modified with a Hexahydrobenzylcarbonate ester attached at the 17-beta hydroxyl position. It belongs to the 19-nor class and contains multiple structural modifications that distinguish it from its parent compound.

Molecular Details

Molecular Formula: C₃₀H₄₀O₄

Molecular Weight: Approximately 464.6 g/mol

Structure Type: 19-nor anabolic steroid

Structural Description

The molecule is based on a 19-nor backbone, lacking the carbon at position 19. It features a ketone group at the C3 position and a conjugated system of double bonds at C9–C10 and C11–C12, in addition to the standard C4–C5 double bond. This extended conjugation significantly alters its interaction with androgen receptors and metabolic enzymes. The defining feature is the esterification at the 17-beta hydroxyl group with a large hexahydrobenzylcarbonate ester, greatly increasing lipophilicity and slowing release.

Functional Significance

The hexahydrobenzylcarbonate ester does not modify the intrinsic activity of trenbolone but controls its release rate and duration. Due to its large and bulky structure, it provides a prolonged half-life typically around 7 to 10 days, allowing for sustained release and less frequent administration. As a 19-nor compound with multiple double bonds, it does not aromatize into estrogen.

Summary

Trenbolone Hexahydrobenzylcarbonate is a long-acting trenbolone ester characterized by a highly modified steroid structure and a bulky ester chain. Its design enables extended release and prolonged activity, distinguishing it from shorter-acting trenbolone variants.
