Half-Life

DHT-derivative with anti-estrogenic properties (weak aromatase inhibitor). Produces muscle density and hardness with no water retention. Best at low body fat. Often used as a 'dry' compound finishing cycle.

Mechanism of Action

Does not aromatize. Acts as a mild competitive aromatase inhibitor, lowering estrogen levels. Binds SHBG, freeing more free testosterone. DHT-derived, so minimal 5α-reduction, but androgenic at scalp.
