Andarine or S4 as its known is a selective androgen receptor modulator (SARM) originally developed to treat muscle wasting diseases and osteoporosis. It has shown promise in preliminary animal studies where it effectively increased bone density, muscle mass, and strength
Andarine is a very versatile and you can use it for cutting, recomposition or bulking.
Andarine has similar properties to “cutting” steroids such as Winstrol and Anavar. By binding to the androgen receptor, Andarine increases fat oxidation. It also decreases lipoprotein lipase (LPL), an enzyme that causes lipid accumulation. This sarm S4 is often compared to Winstrol since it increases vascularity and promotes a very nice “quality” hard look to the user’s muscles with no water retention.
Another great benefit to including Andarine in a cutting protocol is that it’ll prevent the loss of muscle mass while in a calorie deficit. One of the most disheartening outcomes of cutting is the loss of hard earned muscle mass. As S4 has both anabolic and androgenic effects in muscle tissue, it will not only help with fat loss, but maintain and even increase muscle mass when cutting.
Andarine also doesn’t cause the painful lower back and calf pumps associated with other popular steroids/prohormones.
Recomping is when you lose fat and gain muscle at the same time. In fact, this is what the majority of users are looking for. Andarine is a favorite when recomping due to its nutrient partitioning effects. One of the most common SARMS cycles is the SARMS triple stack which is a combination of Ostarine (MK2866), Andarine (S4) and Cardarine (GW501516).
Due to its androgenicity in muscle tissue, Andarine will promote increases in strength without bloat or water retention. The weight gain from S4 may not be that great in comparison to bulking steroids such as deca or Superdrol, but the lean mass and strength gained during the cycle is kept and not lost after the cycle.
