Facts: Ostarine (*S-4) is a Selective Androgen Receptor Modulator produced by GTx Inc, which is currently in the investigational stages of development. A SARM is exactly what it sounds like: a compound (not an anabolic steroid) which has the ability to stimulate the androgen receptor (much the same way as anabolic steroids). Unfortunately, due to its status as a drug still in the developmental stage, most of the research on it has been done in rodents and trials only. |
S-4 is an orally active (and highly bioavailable) selective agonist for androgen receptors which was shown to have anabolic effects in muscle and bone tissue. It has been shown to have no measurable effect on lutenizing hormone (LH) or follicle-stimulating hormone (FSH), but it has been shown to have some effect on prostate weight, with an androgenic potency around 1/3rd of its anabolic potency. Still, this is a good trade-off, because it’s anabolic effect has been measured to be roughly the same as testosterone. It has also been shown to produce dose-dependent increases in bone mineral density and mechanical strength in addition to being able decrease body fat and increase lean body mass. |
Unfortunately, it has a short half-life in humans of only 4 hours, and thus far has only gone through phase II clinical testing in humans. |
