Dragon Pharma’s S4, also known as Andarine, is a selective androgen receptor modulator (SARM) renowned for its ability to enhance lean muscle mass, reduce body fat, and improve vascularity without the androgenic side effects associated with anabolic steroids. With 100 tablets per bottle dosed at 25 mg each, it’s a reliable option for both cutting and recomp cycles in the bodybuilding community.
DRUG DESCRIPTION
S4 (Andarine) was originally developed to combat muscle wasting and osteoporosis. In modern fitness use, it is praised for its tissue-selective binding that helps preserve lean muscle while promoting fat loss. Its mechanism of action mimics the anabolic effects of testosterone in muscle and bone while minimizing unwanted side effects in other organs.
Studies have shown it increases strength and endurance while supporting muscular hardening. Clinical trials confirm its effectiveness as a muscle-preserving compound in caloric deficit conditions.

HOW TO USE S4
S4 is typically run in 6- to 8-week cycles, depending on the user’s goals. For cutting, most users start with 25 mg/day, increasing gradually to 50 mg/day in two divided doses due to the compound’s short half-life. Because some users report night vision side effects at higher doses, a 5-day-on/2-day-off protocol may be used to minimize risk.
Men aiming for a lean cut or recomposition often stack S4 with compounds like MK 2866 (Ostarine) or LGD 4033. Women typically benefit from lower dosages (10–25 mg/day), often stacked with MK 677 (Ibutamoren) to support recovery and growth without masculinization.
POSSIBLE SIDE EFFECTS
- Temporary vision changes (night vision tinting or light sensitivity)
- Fatigue at higher doses
- Suppression of natural testosterone with long-term use
S4 is non-toxic to the liver and does not convert to estrogen. Still, some form of mild PCT, such as Enclomiphene or Clomid, may be required post-cycle depending on dose and duration.
