Benefits of S-23 (Mastorin)

• Promotes dry, lean muscle gains
• Increases vascularity and muscle hardness
• Supports fat loss and improved muscle definition
• May enhance aggression and focus in training
• Non-aromatizing – no estrogen-related side effects

Recommended Usage

The typical dosage of S-23 is 10–30 mg per day, taken in split doses due to its short half-life (~12 hours). It's commonly used in cycles lasting 6–8 weeks. Due to suppression of natural testosterone, a full PCT is required after your S-23 cycle.

What Is S-23 (Mastorin)?

S-23 is a selective androgen receptor modulator (SARM) developed as a potential male contraceptive due to its strong suppression of testosterone. However, it gained popularity in performance enhancement circles for its ability to produce dense, dry muscle and promote fat loss without the estrogenic side effects of steroids.
