ANDARINE S-4 / 25mg * 50

S-4 (Andarine) is a SARM developed for muscle hardening and toning, and fat loss, and is often used during weight loss and cutting phases. It is more effective at tightening and defining muscles than building muscle.
Mechanism of action: Andarine binds to androgen receptors and acts on muscles and bones. It is particularly effective in reducing fat and tightening muscles, helping to maintain muscle mass while losing weight. It also helps to reduce the risk of fractures and increase muscle strength by increasing bone density. It is said to have relatively mild testosterone suppression.
