S4 (also known as Andarine or Acetamidoxolutamide), is one of the most potent Selective Androgen Receptor Modulator(SARMs) currently available. S4 excels at sustaining lean muscle mass while simultaneously stimulating fat elimination.
HALF LIFE: 4 HOURS.
S4 attaches to androgen receptors (AR) just as traditional androgens do, however the compound is mostly active in skeletal muscle (selective anabolic activity). Per equivalent dosage, S4 is approximately one third as anabolic as testosterone. S4 does not exhibit androgenic activity outside of skeletal muscle tissue.
It can decrease the size of the prostate if taken as recommended. It is administered orally.
It’s shown to be beneficial for muscle degeneration, osteoporosis and benign prostatic hypertrophy treatment. Aside from preserving lean body mass, S4 can also help improve it.
Aside from its muscle building advantages, S4 can prevent gynecomastia (enlarged breasts in men) and can help boost your overall health.
By binding to the androgen receptor, S4 stimulates a faster rate of protein synthesis in skeletal muscle, allowing for faster recovery and faster tissue building. Because androgenic activity is absent outside of skeletal muscle, negative effects on the prostate and other sexual organs are avoided.
Fat elimination or “cutting” is the most effective use for S4 Andarine.
Andarine’s properties are very similar to the popular steroids Anavar and Winstrol, the only difference is that S4 can better provide lean muscle gains. S4 displays the same binding resemblance to AR, hence presenting similar fat burning effects. S4 can also minimize LPL (lipoprotein lipase) – an enzyme that causes lipid accumulation.Furthermore, Andarine also decreases fat while maintaining and even boosting muscle mass in a hypocaloric environment. It also improves vascularity for that “aesthetic” chiseled look with minimal to no water retention. Unlike steroids, it won’t affect your joints but reinforce muscle mass and power instead. You can also say goodbye to painful pumps. Most researchers report using 50 mg for 6-8 weeks.
Use S4 with a more anabolic SARM such as Ostarine for better recomp results as you’re aiming to gain muscle while losing fat. Recommended intake is 50-75 mg for 4 to 8 weeks.
The strength gains that Andarine produces moderately quick gains that can be maintained much easier than those seen with androgenic-heavy steroids. S4 makes you feel good all over. Suggested dosage is 50mg.
Every compound has side effects, both known, and potentially unknown.
The most commonly reported side effect of S4 is yellow-tinged vision, and also a reduction in quality of night vision. The dose at which this occurs varies widely from individual, and is more consistently seen in high dosing schemes (75mg/ED++). Symptoms disappear when the compound is discontinued.
