Mesterolone (Proviron)
DHT derivative oral AAS. Weak anabolic, strong androgen. Used as an anti-estrogen adjunct and SHBG reducer to increase free testosterone.
Overview
DHT derivative oral AAS. Weak anabolic, strong androgen. Used as an anti-estrogen adjunct and SHBG reducer to increase free testosterone.
Dramatically lowers SHBG (increases free testosterone), mild anti-estrogenic effect, does not significantly suppress HPTA at low doses, minimal liver stress (not C17-alpha alkylated in the traditional sense), can worsen lipids moderately, may increase DHT-related sides (hair loss, prostate)
Compound Guide
Structure: 1-methyl DHT. Oral bioavailability via 1-methylation rather than 17-alpha alkylation, making it one of the least hepatotoxic oral AAS.
Dosage:
- SHBG reduction / feel-good: 25-50mg/day
- Anti-estrogen adjunct: 50mg/day alongside aromatising compounds
- Enhancement: 50-75mg/day (limited anabolic effect — used for its androgenic and SHBG-lowering properties)
Administration:
- Oral tablet, split into 2 doses/day (morning and evening)
- Can be run for extended periods (8-12+ weeks) due to mild liver profile
Key Notes:
- Primary value is dramatically lowering SHBG — more free testosterone from your existing testosterone base
- Provides a "hardening" effect and improved mood/libido via increased free androgens
- Very weak anabolic — do not expect significant muscle gains from Proviron alone
- One of the few orals that can be run long-term without major liver concern
- Can accelerate male pattern baldness in predisposed individuals (DHT derivative)
- Useful during PCT to maintain androgenic activity and libido while HPTA recovers
- Monitor lipids — can lower HDL moderately
