Overview
Extremely potent oral androgen (veterinary compound — originally used to suppress estrus in dogs). Used by some bodybuilders pre-competition or pre-contest for acute aggression and CNS stimulation. Among the most androgenic compounds ever used by athletes (estimated ~1800–2500% androgenic relative to methyltestosterone). Harm reduction: Doses above 5mcg dramatically increase hepatotoxicity and cardiovascular risk. Duration strictly limited to 2–4 weeks maximum. Significant progestogenic activity — monitor prolactin. Very short half-life (~4 hours) — used only on training/competition days. Extremely hepatotoxic — TUDCA mandatory.
Mechanism of Action
Progestin-derived androgen. Binds androgen receptor with very high affinity. Also binds progesterone receptor — progestogenic side effects expected. No aromatisation to estrogen. 17-alpha-alkylated — significant hepatotoxicity.
