Ostarine (MK-2866) - Magnus


Is a selective androgen receptor modulator (SARM) that has become a popular supplement among athletes, bodybuilders, and fitness enthusiasts. This product is distributed by Magnus Pharmaceuticals and is known for its potential benefits in promoting muscle growth, improving recovery, and maintaining muscle mass during caloric deficit.


Ostarine belongs to the category of SARMs, meaning it selectively influences androgen receptors in the body. This means it primarily focuses on improving muscle tissue and bone without increasing estrogen levels or other undesirable effects associated with anabolic steroids. MK-2866 was developed for treating conditions such as osteoporosis and muscle wasting, but it is currently widely used in the fitness and bodybuilding community.


Ostarine offers a range of benefits, making it a popular supplement for fitness enthusiasts and bodybuilders:

  • Increases muscle mass: Ostarine promotes protein synthesis, which can lead to faster muscle growth.
  • Improves recovery: Many users report faster muscle recovery after intense workouts, allowing them to train harder and more frequently.
  • Maintains muscle mass: During caloric deficit, muscle loss often occurs. Ostarine can help protect muscles during dieting.
  • Enhances performance: Some users report improved performance and endurance during workouts.


Ostarine is known for its ability to selectively target androgen receptors in muscles and bones. This means it has anabolic effects on these tissues while minimizing the side effects associated with traditional anabolic steroids. This is because it selectively binds to these receptors, meaning it does not affect other parts of the body as traditional steroids might.

Side Effects:

Although Ostarine is generally well-tolerated in most cases, some people may experience side effects. Possible side effects include:

  • Suppression of testosterone production: Although less likely than with steroid use, some users may experience temporary suppression of testosterone production. Therefore, post-cycle therapy (PCT) is recommended after Ostarine cycles.
  • Possible risk of liver issues: In some individuals, Ostarine may cause elevated liver enzyme levels, so it is important to monitor liver health during use.
  • Possible effects on the heart: Animal studies suggest that Ostarine may affect heart and vascular health, but human research is limited.


Recommended dosages of Ostarine may vary depending on individual needs and goals. Typical dosages range from 10 mg to 30 mg per day. It is important to start with a lower dose and gradually increase it to see how your body responds. Ostarine is usually taken for 8 to 12 weeks, followed by a period of rest.


Ostarine (MK-2866) is a synthetic compound developed for treating muscle wasting and osteoporosis, but it is currently primarily used in the fitness and bodybuilding community to promote muscle growth and enhance performance. The chemical formula of MK-2866 is C19H14F3N3O3, and its molecular weight is 389.33 g/mol.

In conclusion, it is important to emphasize that before starting Ostarine or any other supplement, you should consult with a doctor or qualified nutrition expert, especially if you have any health issues or are taking other medications. Adhering to recommended dosages and monitoring side effects is also crucial for maintaining health and safety when using this product.
