What Are The Benefits of Andarine S4?
Andarine is an orally active partial agonist for androgen receptors, S-4 is effective in not only maintaining lean body mass but actually increasing it. Andarine is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects. This suggests that it is able to competitively block binding of dihydrotestosterone to its receptor targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side effects associated with the anti-androgenic drugs traditionally used for treatment of BPH.
Usages of Andarine S4
For cutting and Strength Gains:
As for the properties of S4, andarine is often compared to winstrol or anavar, while S4 provides better effects on lean muscle gains. What’s more, Andarine also decreases fat while maintaining and even boosting muscle mass in a hypocaloric environment.
Recommended for recomping is 50-75 mg for 4 to 8 weeks. If S4 is used with a more anabolic SARM such as Ostarine, the results of recomping will be better if you’re aiming to gain muscles while losing fat.
