Oxandrolone Var

An FDA-approved oral steroid (Anavar) used to help people regain weight after serious illness, surgery, major injury, or burns. Human studies support that it helps restore lost weight and muscle, and it's considered one of the gentler steroids, though it still lowers natural testosterone and affects cholesterol.

Also known as Anavar, Lonavar, Vasorome, Oxandrin, Provitar, Protivar, Oxandrolona
