What is MENT (Trestolone Acetate)?
MENT (Trestolone Acetate — potent synthetic 19-nor androgen (injectable)) is the acetate ester of trestolone — C₂₁H₃₀O₃, MW 346.5. 7α-methyl-19-nortestosterone acetate with ~10× greater AR binding affinity than testosterone. Unlike testosterone, MENT cannot be converted to DHT by 5α-reductase (7α-methyl group blocks reduction). Partially aromatises to 7α-methyl-oestradiol. Originally developed as a male hormonal contraceptive. High progestogenic activity.
Research Applications
High-Affinity Synthetic Androgen Research
~10× greater AR binding vs testosterone — high-potency androgen receptor studies
5α-Reductase Resistance
7α-methyl group blocks 5α-reduction to DHT — tissue-selective androgenic activity model
Male Hormonal Contraception Research
Original MENT application — HPT axis suppression for male contraception studies
Progestogenic Activity
High PR agonism — progesterone receptor cross-reactivity and progestogenic co-effects

Frequently Asked Questions
How do I reconstitute this peptide?
QSC injectable solutions are supplied ready-to-use — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier (oil or aqueous). Draw using a sterile syringe appropriate for the solution viscosity.
How should this peptide be stored?
Oil-based solutions: store at room temperature (15–25°C), away from direct sunlight — do not refrigerate as cold temperatures can cause crystallisation. Aqueous solutions: store at 2–8°C. Properly stored, injectable solutions are stable for 2–3 years.
What purity is this QSC compound and how is it verified?
All QSC injectable compounds are ≥99% pure by HPLC on every production batch, with MS-confirmed identity. COA is published on the product page and independently verifiable at verify.janoshik.com.
