Ostarine MK-2866 is a SARM (Selective Modulator for Androgenic Receptors) developed by GTx for the prevention and treatment of muscular atrophy. It may be prescribed cachex and sarcoma as well as hormone replacement therapy.
Ostarine belongs to the class of chemicals known as SARMS. SARMS creates anabolic activities for specific androgen receptors. Compared to Testosterone and Other Anabolic Steroids, SARMS has the advantage of not having androgenic activity in non-muscle tissues. Ostarine is effective in maintaining and increasing lean mass.
How does it work?
SARMS binds to androgen receptors and shows anabolic activity in bone and muscle tissues.
Activation of androgen receptors
Activation of the androgen receptors will alter gene expression and increase the protein synthesis that builds the muscles. Basically, SARMS, such as ostarine, causes muscle growth in the same way as steroids, but without advancing prostate and other genital growth.
In particular, ostarine affects almost exclusively muscle tissue. Therefore, it not only provides treatment for many diseases that cause muscle loss (from age-related illnesses to AIDS or cancer), but also has a huge potential for building slim masses for bodybuilders and athletes, as well as minimizing atrophy during periods of recovery or a similar recovery.
Ostarine MK 2866 is anabolic for all SARMs, so it is used more in the muscle strengthening stages. Total weight gain can not be compared to gross investment steroids, but all of these gains are low-fat mass. Benefits are fairly easy to maintain, and users typically see up to 3 kg of low mass over a 8 week cycle at 25 mg daily (high calorie diet). The most common dose is 25 mg daily for 8 weeks. Side effects with steroids are not present in this cycle. Usually with ostarine, the higher the dose, the greater is the suppression. Although the suppression is minimal and not comparable to the causes caused by the steroid period, all of the ostarine periods longer than 4 weeks require a small 3 week TPC without SARM requirements.
Ostarine would be placed in this cycle in order to maintain low fat mass when calories decrease. The protocol 15-20 mg per day for 6-8 weeks is interesting because there would be no adverse effects or high attenuation. However, it should be stressed that the results would be better with S-4 with SARM.
