Half-Life

East German Olympic program compound. Modified Dianabol with a chloro group that prevents aromatization. Steady, lean gains without water retention. Less liver stress than Dianabol but still oral 17α-alkylated.

Mechanism of Action

17α-alkylated for oral bioavailability. Does NOT aromatize (4-chloro modification blocks aromatase). Moderate AR binding. Binds SHBG effectively. More gradual and 'cleaner' gains than Dianabol.
