Enobosarm (Ostarine, MK-2866, GTx-024) - affects both muscle and bone, intended mainly for osteoporosis but also general treatment for andropause and reversing muscle sarcopenia in the elderly and for cachexia in cancer patients.Nonsteroidal selective androgen receptor modulator (SARM) used in the treatment of osteoporosis and muscle wasting in animal models. A potential compound for the treatment of hypoactive sexual desire disorder.
Ostarine, also known as MK-2866 is a SARM (selective androgen receptor module) created by GTx to avoid and treat muscle wasting. It can later on be a cure for avoiding atrophy (total wasting away of a body part), cachexia, sarcopenia and Hormone or Testosterone Replacement Therapy. This type of SARM cannot only retain lean body mass but as well as increase it. Ostarine is often mistaken as S1 but S1 was created earlier and is no longer going through more expansion.
How Ostarine Works?
SARMS bind to the androgen receptor (AR) and shows osteo (bone) and myo (muscular) selective anabolic activity. The tying and stimulation intensifies protein synthesis and builds muscle.
Ostarine causes muscle growth just like steroids but it won't produce negative side effects commonly found in anabolic steroids and prohormones such as prostate and other secondary sexual organs.
MK-2866 uses its anabolic effects on muscle tissue fully so it's not only a potential for curing muscle wasting ailments but also it has great potential for muscle building for athletes, bodybuilders and fitness buffs. It is also an agent to reduce degeneration during recovery times from serious surgery or similar conditions.
Ostarine has undergone 8 scientific trials by GTx with about 600 subjects plus 3 efficiency studies. A 4-month Phase IIb medical trial including 159 patients have shown a complete boost in total lean muscle mass compared to placebo and the secondary goal of increasing muscle strength.
In terms of bodybuilding, Ostarine users have proven that MK-2866 can help improve lean muscle mass and strength levels.
Uses of MK-2866
For Bulking Shines best when used for gaining lean muscle (bulking) as it is the most anabolic of all the SARMS. Suggested dosage is 25 mg for 4-6 weeks. PCT is not necessary. An increase of 6 lbs. of lean, keepable gains can be observed during this period. You can take Ostarine as high as 36 mg for 8 weeks BUT only if you weigh 210 lbs. Suppression is expected in higher doses so PCT after a cycle is a must.
For Recomping Ostarine shines in recomping due to its nutrient portioning results. Calorie is used to build muscle which helps in weight loss and enhancing muscle mass and strength. Suggested dosing is 12.5-25 mg for 4-8 weeks. Your diet must contain 30% of lean sources of protein to achieve the best recomp result.
For Cutting MK-2866 can help cut whilst preserving muscle gains and decreasing calories. Suggested dosing is 12.5-15 mg for 4-6 weeks.
