Just like every other SARM, Andarine (S-4) works by attaching to androgen receptors selectively. According to the studies, we also know that it is milder than others in its class because it is a partial agonist of the androgen receptor. However, don’t let that fool you into thinking it won’t still give you some solid results.
Another cool thing Andarine (s-4) does is that studies showed it had anti-DHT (dihydrotestosterone) effects in the body. This means it will block sex hormones which cause things like the shedding of head hair and enlarged prostate.
Andarine (S-4) is very mild, so do not expect crazy changes in weight, strength, and aggression like you would from using anabolic steroids. However, the benefits of using it are stronger bones, lean muscle mass, and mild strength gains. Users also say, when properly stacked, it is great for fat loss too while in a carbohydrate and calorie deficit.
