Oxandrolone

Oxandrolone is a 17α-alkylated androgen and an anabolic steroid. Like other steroids, it acts intracellularly in target cells by binding to the intracellular androgen receptor. This binding initiates a series of events leading to growth, differentiation, and synthesis of various enzymes and other functional proteins, aiming for anabolic effects.
