S-4 Andarine

S-4 is a Selective Androgen Receptor Modulator (SARM). S-4 is the weakest in anabolic activity, but one of the most androgenic, being 1/3 as strong as testosterone at binding to the androgen receptor.

S-4 can cause a drying out of the muscle and the skin surrounding it by binding very well to the androgen muscle receptors, hardening and sharpening the muscle.

S-4 can cause significant weight loss by binding to the androgen receptors – it allows fat to be oxidized and displays potent nutrient partitioning affects, causing more calories to be used to build and repair muscle. In addition, it has mild anti-estrogenic qualities and will lower estrogen over a 4-week period.


MK-677 reacts with the body similarly to Human Growth Hormone (HGH) that many people use for weight loss and muscle building. This is synthetic growth hormone, consisting of 5 amino acids. It is a selective growth hormone that doesn’t release cortisol (a steroid that causes the body to hold onto fat, which is released by the adrenal glands when the body is facing stress). There are more benefits than muscle building, including improved sleep quality, increased muscle and connective tissue growth, boosted immune system and decreased fat, among other health benefits that are long term, for example, increasing bone density. It will not affect the natural production of growth hormones, compared to other growth hormones.
