S4, also known as Andarine, is the most investigated and researched modulator so far. It is also the most versatile ever created. Like most modulators, the primary purpose of S4 aimed to develop an alternative treatment to age-related muscle wasting, osteoporosis, and similar symptoms of hypogonadism, or end-stage renal disease. S4 binds incredibly well to the androgen receptors of bone and muscle. While it doesn’t tend to impress in terms of building pounds upon pounds of muscle, it has amazing effects on fat loss. Why? S4 is the least anabolic, yet most androgenic modulator. When androgenic hormones or modulators attach to the androgen receptors in the adipose tissue they trigger fat oxidation.
