Extremely potent oral AAS. 17-alpha alkylated. Used for strength and aggression in powerlifting and pre-contest hardening. Not a mass builder.
Overview
Extremely potent oral AAS. 17-alpha alkylated. Used for strength and aggression in powerlifting and pre-contest hardening. Not a mass builder.
Severe liver stress (one of the most hepatotoxic common orals), significantly elevates ALT/AST/GGT, dramatically worsens lipids, does not aromatise, strong HPTA suppression, can elevate haematocrit, increases aggression
Compound Guide
Structure: 17-alpha alkylated, 9-fluoro, 11-beta-hydroxy testosterone derivative. Extremely androgenic (1900:1 androgenic:anabolic ratio on paper).
Dosage:
- Strength / pre-workout: 10-20mg taken 30-60 min before training
- Pre-contest: 20-30mg/day for 2-4 weeks maximum
- Advanced: 30-40mg/day (extreme liver toxicity — not recommended beyond 2-3 weeks)
Administration:
- Oral tablet, take pre-workout or split AM/pre-workout
- NEVER exceed 4-6 weeks of continuous use
Key Notes:
- Used almost exclusively for strength, aggression, and contest-day hardening — not a mass builder
- One of the most hepatotoxic oral AAS — liver values can spike dramatically within days
- Keep cycles very short (2-4 weeks) with mandatory liver support: TUDCA 500-1000mg/day, NAC 1.5g/day
- Monitor liver enzymes weekly during use if possible
- Does not aromatise — no estrogen management needed
- Dramatically worsens lipids — HDL can drop to single digits
- Not suitable for beginners under any circumstances
Doses of TUDCA and NAC that actually protect the liver on a harsh oral, and the ones that do nothing: TUDCA and NAC doses that actually protect your liver on cycle.
