Selective Androgen Receptor Modulator
Ostarine ~ 4-cyanophenoxy)-N-[4-cyano-3-(trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide)
Ostarine (MK-2866) is a Selective Androgen Receptor Modulator. 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). 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 (1). 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 and mechanical strength in addition to being able decrease body fat and increase lean body mass.
Selective androgen receptor modulators (SARMs) bind to the androgen receptor and demonstrate osteo (bone) and myo (muscular) anabolic activity. Binding and activation of the Androgen receptor alters the expression of genes and increases protein synthesis, hence builds muscle. So in essence, SARMs such as Ostarine causes muscle growth in the same manner as steroids, however unlike testosterone and other anabolic steroids and prohormones, SARMs (as nonsteroidal agents) don’t produce the growth effect on prostate and other secondary sexual organs.
Ostarine in particular exerts its anabolic effects on muscle tissue almost exclusively. So not only does it represent a new potential treatment option for a wide spectrum of conditions from muscle wasting diseases (from age-related to AIDS or cancer-related), but is also has immense potential for muscle building for Bodybuilders, fitness, athletes and an agent to minimize atrophy during recovery periods from serious surgery or similar situations.
