Androsterone

Tier 3 — weak evidence · Hormone · Pheromone claims

A weak androgen metabolite marketed as a prohormone and pheromone supplement. No clinical evidence supports meaningful testosterone-raising effects when taken orally. Pheromone claims in humans lack rigorous scientific support. Expensive with no demonstrated benefit. May be prohibited in some sports — check anti-doping rules before use.

Dose: No established effective dose; not recommended; lacks clinical evidence for any claimed benefit
