Ostarine. What is it?

Ostarine (MK-2866, Enobosarm) is an innovative drug of the SARMs class which makes an amazing effect on the growth of muscle mass and increase of endurance, speed and strength. MK-2866 was made by GTx Incorporated for the treatment of cachexia, sarcopenia and atrophy. The action of Ostarine in many respects reminds the effect of the use of anabolic steroids, however, in comparison with them, Ostarine, practically, has no side effects. The fact is that unlike steroids, MK-2866 is able to exert an anabolic effect exclusively on bone and muscle tissues, without activating the receptors of other tissues due to its high selectivity.

Muscle mass, which you can increase with Ostarine, will be less than with the use of anabolic steroids, however, the weight is typed due to dry muscles. Moreover, the result of Ostarine consumption is fairly easy to keep. On an 8-week course with the required diet up to 3.5 kg of lean muscle mass is typed without problems, which explains the value of Ostarine in bodybuilding.


  • An increase in dry muscle mass without loss of effect after discontinuation;
  • Effective fat burning;
  • Restoration of damaged joints and strengthening of bones;
  • Increases speed and endurance.


  • Practically non-toxic to the liver;
  • Does not make an effect on the axis of the hypothalamus-pituitary-testicles;
  • Does not affect the pressure;
  • Does not stimulate prostate growth;
  • Not aromatized;
  • Positively affects the joints and bones;


As a result of a 12-week research compared to patients taking placebo, the following changes were recorded in men and women taking 3 mg of drug per day:

  • The average fat loss is 300 g;
  • The average increase in muscle mass is 1.4 kg;
  • An increase in the level of liver enzymes (ASAT, ALAT);
  • Decrease in the level of high density lipoproteins while maintaining the existing level of low density lipoproteins;

Ostarine was equally effective for both sexes.

Ostarine (SARMs, MK-2866, Sarms) has a large number of positive reviews from both taking it for weight gain, and for fat burning and Post Cycle Therapy. Almost all of them fix a significant increase of muscle mass within a week after the start of using Ostarine, and note an increase in endurance.

How to use

The half-life of MK-2866 is 24 hours, so taking the drug once a day is the most optimal option to maintain the effect. The course the length varies from 3 to 8 weeks and depends on the desired result (mass gain / fat burning / PCT, etc.). With a body weight of less than 90 kg, the recommended norm is 12.5-25 mg (1-2 capsules). Post Cycle Therapy in this case is not important. If your weight exceeds 95 kg, it is recommended to increase the daily dose to 37.5 mg (3 capsules), in this case PKT is a prerequisite.

Side effects

When observing the necessary recommendations, there are no side effects from the application of Ostarine. A slight decrease in the level of IGF-1 is recorded, which is easily corrected by adding to the diet of sports supplements that increase its secretion (zinc, arginine, melatonin, creatine, etc.). With a significant excess of the daily rate, the MK-2866 is also able to suppress the production of its own testosterone. To prevent the occurrence of side effects, the use of PCT is recommended.
