Trestolone (MENT)
7-alpha-methyl-19-nortestosterone. Extremely potent 19-nor AAS. Can replace testosterone as a cycle base. Available as acetate ester.
Overview
7-alpha-methyl-19-nortestosterone. Extremely potent 19-nor AAS. Can replace testosterone as a cycle base. Available as acetate ester.
Very strong HPTA suppression, aromatises to 7-alpha-methyl-estradiol (not detected on standard E2 assays — use sensitive LC-MS/MS), significant lipid impact, may elevate prolactin (19-nor derivative), does not convert to DHT, highly anabolic
Compound Guide
Ester: Acetate (most common). Very short ester requiring daily or twice-daily injection. No-ester (TNE-style) formulations also exist.
Dosage:
- Low / TRT-replacement trial: 5-10mg/day (acetate)
- Enhancement: 10-25mg/day for 8-12 weeks
- Advanced: 25-50mg/day (significantly increases side effect risk)
Injection Protocol:
- Inject daily (acetate ester) — SubQ with insulin syringe is practical at these low volumes
- IM also viable: 27-30g needle, delts/VG
Key Notes:
- One of the most potent AAS by mg — effective doses are very low compared to testosterone
- Aromatises to 7-alpha-methyl-estradiol which does NOT show on standard E2 immunoassays — you must use LC-MS/MS estradiol testing to monitor
- Can serve as a testosterone replacement (maintains libido, mood, erectile function) but long-term safety data is limited
- 19-nor derivative: may elevate prolactin — have Cabergoline on hand
- No DHT conversion means less hair loss and prostate impact, but also no DHT-mediated neurological benefits
- Very suppressive to HPTA — aggressive PCT required
