Ostarine, more commonly goes by the name MK-2866, Enobosarm or Ostabolic. It is a well-known SARM (Selective Androgen Receptor Modulator) which was primarily manufactured to prevent and cure muscle wasting as a result of increasing age or other motor diseases by replacing body’s growth hormones. Although this was the main concept used by Merck, GTX and Inc, MK-2866 is indiscriminately used in today’s modern fitness industry for its wondrous effects on strength and muscle building.

Mechanism of action

Ostarine comes under the umbrella of drugs called SARM (Selective Androgen Receptor Modulator). This simply means Ostarine has more affinity to the androgen receptors, preferably those present in the bones and muscles. After binding to their desired receptors, the drug enhances anabolic activities like protein synthesis and reduces any other catabolic actions in the body. This results in growth, regeneration of muscles and promotes increase in connective tissues. Ultimately, MK2866 strengthens muscles; increases bone density and allows faster recovery.


On a broader aspect, Ostarine mimics the action of testosterone on the muscles and joints. Testosterone is the male hormone, responsible for development of secondary sexual characteristics. But, the use of androgens is weaning away after the emergence of Ostarine for the following reasons.

  1. Although traditional steroids also enhance the action of testosterone, they act as non-selective activators which lead to collateral side effects like suppression of testosterone levels and additionally increasing the estrogen levels. On the contrary, SARM like Ostarine selectively and specifically activate the androgen receptors present in the bones and muscles. This property eliminates the deleterious side effects, making Ostarine the most desirable drug in the muscle building industry.
  2. Virilization is one of the primary concerns related to performance enhancing drugs. With proper dosage of Ostarine, there is no risk of virilization. In fact, this characteristic is most appreciated by female athletics who desire to outperform in the fitness industry.
  3. Owing to its anti-catabolic action on the body, users could use MK-2866 to prevent muscle wasting. This enables to preserve the gained lean muscle and shed excess body weight even with low calorie diet.
  4. The phenomenal effect of Ostabolic is its healing property. Injuries such as muscle pain, sprains, fractures are inevitable collateral issues related to bodybuilding industry. Fortunately, Enobosarm promote healing in tissues, reducing the recovery period which act as a knight in shinning armor for athletics.
  5. Unlike other performance enhancers, Ostarine is not hepatotoxic due to its non-methylated property.


1. Role in orthopedics

This was the main idea behind development of Ostarine. Osteoporosis is a concern of senility, especially in post-menopausal women. In osteoporosis, there is increase in bone degeneration which leads to pathological fracture even with minor trauma. Ostarine promotes increase in bone mineral density, growth of bones and connective tissues, reduces bone breakdown and allows rapid healing of fractures. This is an imperative role in bone degenerative issues and can be used as an alternative treatment of age-related hip and pelvic fractures.

2. Role in oncology

Apart for its wondrous muscle building benefit among athletics and bodybuilders, Ostarine can also be used to prevent muscle wasting and build lean muscle mass in cancer patients with cachexia and muscle atrophy.

3. Role in reproduction

Ostarine does not undergo aromatization. This simple means with Ostarine, testosterone is not converted to estrogen, i.e. there is no increase in estrogen levels. Increased testosterone levels in body are responsible for increasing strength and endurance. In addition, this could treat age onset conditions like erectile dysfunction, loss of libido and reduced sexual performance.

4. Helps maintain heart and brain health

Experts have concluded that Ostarine reduces cholesterol and triglyceride levels in body. In fact, this counteracts obesity, the main determinant of vascular diseases like heart attack and stroke. Undoubtedly, Obesity is one of the most worrisome issues among today’s modern society where people are more likely to be in front of computers or desks.

Although Ostarine has been proved by experts to be a phenomenal performance enhancer, use of MK-2866 has been banned by WADA (World Anti-Doping Agency).

  1. 50mg of ostarine per day will not damage your kidneys and liver not because ostarine is not considerably toxic, but because blood thickening from altered protein synthesis even on bone tissues will have you have a heart attack at even 1mg above 20mg/day, 50 thus is an 1 way ticket
