What is Ostarine MK-2866
Overview
Ostarine (MK-2866), also known as enobosarm, is a popular nonsteroidal selective androgen receptor modulator (SARM). It is designed to selectively target androgen receptors in muscle tissue, which means it reduces unwanted side effects associated with traditional anabolic steroids. As well, it does not aromatize so there is no conversion to estrogen regardless of dosing.
Ostarine was initially created to treat muscle wasting as a result of increased age or motor diseases. It is uniquely well tolerated with minimal side effects and an extremely attractive safety profile making it a performance enhancer that both men and women can safely enjoy.

Ostarine MK-2866 Benefits:
Muscle Mass
Amazingly, Ostarine has been clinically proven to significantly increase lean body mass in a dose dependant manner without androgenic side effects in men or virilization in women and without statistically significant liver toxicity.
Decreased Body Fat:
Ostarine has been clinically shown to reduce total fat mass with daily doses as low as 3 mg. This decrease in bodyfat was demonstrated without any changes in diet or exercise in test subjects. Ostarine has also demonstrated the ability to improve insulin sensitivity in test subjects as well as reduce blood glucose levels, both of which are critical drivers of reducing bodyfat.
Side Effects of Ostarine
Ostarine is well tolerated by both men and women but some side effects are reported in a dose dependant manner such as temporary hormonal suppression, hair shedding, decreased sleep quality, and joint stiffness.
The Bottom Line:
Ostarine is considered the ‘mildest’ of all SARMS since it is so well tolerated by both men and women and makes an excellent choice for beginners as well as any researcher who’s primary goals include reducing body fat or recomping their physique. For men, I highly recommend a dose of 25 mg daily, while women should take 5 mg to a maximum of 10 mg daily. For best results, stack Ostarine with compounds that fit your goals and risk tolerance such as Cardarine and/or RAD-140.

As always, before starting your research, it’s important to ensure sure you only use products of the highest purity and potency from trusted sources such as PureRawz & BehemothLabz.
