SARMs Raw Powder Ostarine MK 2866 CAS 841205-47-8 For Muscle Building

Ostarine belongs to a class of chemicals know as SARMs or selective androgen receptor modulators. SARMs create selective anabolic activity at certain androgen receptors. In comparison to testosterone and other anabolic steroids, the advantage of SARMs, is they do not have androgenic activity in non-skeletal muscle tissues (less side effects). Ostarine is effective in maintaining and increasing lean body mass. SARMS such as Ostarine cannot be aromatized, concentrating all their effects to AR binding and not to metabolic conversion into androgens/estrogens.
What are SARMs (Selective Androgen Receptor Modulators)?

Selective Androgen Receptor Modulators (abbreviation: SARMs) are newly discovered molecules which bind to specific androgen receptors in the human body (for example bone and muscle tissue). They produce similar effects to anabolic steroids but are very specific in their action and thus not producing the various undesirable side effects associated with steroids.

In contrast to steroids, which are usually injected, SARMs are delivered orally. They provide the opportunity to design regimens that selectively target the androgen receptors in different tissues. Only the ones which are the target of the therapy will respond as they would to testosterone, while the rest of the body is unaffected. Many SARM types exist (aryl propionamides, quinolinones, bicyclic hydantoins, quinolines), though aryl propionamides such as ostarine, andarine/S-4, and S-23 are the most advanced SARMs so far.
