⚙️ Mechanism of Action

Nandrolone Phenylpropionate binds to androgen receptors to stimulate protein synthesis, enhance nitrogen retention, and increase collagen production. Its properties support joint lubrication, reduce muscle breakdown, and promote lean muscle development. Unlike testosterone, it converts to estrogen at a slower rate and can increase prolactin, which should be monitored during cycles.
