Chemical Identity

Trestolone Acetate (MENT) is a synthetic derivative of Nandrolone, modified with an Acetate ester attached at the 17-beta hydroxyl position. It also features a 7-alpha methyl group, which distinguishes it structurally from other 19-nor compounds.

Molecular Details

Molecular Formula: C₂₃H₃₂O₃

Molecular Weight: Approximately 356.5 g/mol

Structure Type: 19-nor anabolic steroid

Structural Description

The molecule is based on a 19-nor testosterone backbone, meaning it lacks the carbon atom at the C19 position found in testosterone. It retains a ketone group at the C3 position and a double bond between C4 and C5. A defining structural feature is the addition of a methyl group at the 7-alpha position, which enhances resistance to metabolic breakdown and increases receptor binding affinity. The 17-beta hydroxyl group is esterified with a short acetate ester, resulting in relatively low lipophilicity and faster release compared to longer esters.

Functional Significance

The acetate ester does not alter the intrinsic anabolic or androgenic activity but controls the release rate and duration of action. Due to its short ester chain, Trestolone Acetate has a relatively short half-life, leading to rapid onset and requiring more frequent administration to maintain stable levels. As a 19-nor compound, its structure allows interaction with multiple hormone pathways, contributing to its distinct activity profile.

Summary

Trestolone Acetate is a fast-acting 19-nor derivative characterized by structural modifications such as the absence of C19 and the presence of a 7-alpha methyl group. Its acetate ester enables rapid release, while its core structure contributes to its potent biological activity in research and experimental settings.
