Ostarine Powder (MK-2866) | 2 Grams



SKU: 4-1 Category:


The most popular and most widely studied selective androgen receptor modulator (SARM), Ostarine —also called MK-2866, GTX 024, or Enobosarm —arrived on the scene back in the late 1990s as an experimental treatment for osteoporosis and certain diseases that cause muscle wasting and muscle loss. Ostarine is the closest SARM to being approved for medical treatment and is currently in phase II clinical trials. Like SARMs in general, MK-2866 targets androgen receptors on a selective basis and avoids generating the kinds of harmful side effects associated with substances like testosterone or anabolic steroids.

This selectivity provides Ostarine an opportunity to be studied in female and elderly test subjects when testosterone and many other anabolic treatments are unfavorable. MK-2866 has been observed as generally safe and well tolerated at doses up to 18mg per day for 12 months in female cancer patients. Unlike testosterone and most other androgen receptor mediated anabolic agents, MK 2866 is orally bioavailable so it does not require injection for proper absorption. Sports Technology Labs is the best place to buy Ostarine online.

MK-2866 has demonstrated a variety of potential benefits in research, such as:

  • Increased strength
  • Increased lean muscle mass
  • Increased energy
  • Improved bone health
  • Improved heart health
  • Weight loss
  • Enhanced connective tissue recovery

However, MK 2866 has not been approved by the Food and Drug Administration (FDA) for human consumption at the present time. It should be considered for research use only.

More research needs to be done on MK 2866. Nonetheless, there have been several studies indicating that MK-2866 has considerable promise as a growth and recovery enhancing drug:

  • A 2011 study showed that MK2866 significantly boosted lean body mass and overall physical functionality in elderly men and postmenopausal women [1].
  • A study published in 2019 found that ostarine enhanced bone healing in Sprague-Dawley rats whose ovaries had been removed [2].
