What it is
An investigational non-steroidal selective androgen receptor modulator (SARM) studied in oral form.
How it works
Selective androgen receptor agonist with preferential activity at androgen receptors in muscle and bone relative to prostate and other androgenic tissues.
Where it's used
Investigated in early-phase clinical research for muscle wasting and breast cancer. Listed on the WADA prohibited list.
Regulatory status
Not FDA-approved; investigational compound. Sale as a dietary supplement is prohibited by the FDA.
Tracking it
RAD-140 is oral, which makes consistency the whole game — a simple daily check-off with a reminder beats memory every time. with a half-life of about 2.5 days (60 h), a dose log also lets a tracker model the relative amount still in your system between doses.
