What is MK-2866 or Ostarine?

Ostarine or MK-2866 (also known as Enobosarm or GTx-024) is a selective androgen receptor modulator or SARM developed by GTx and formerly by Merck& Company. It binds androgen receptors and demonstrates osteo (bone) and myo (muscle) anabolic activity. MK-2866 has anabolic effects on certain androgen receptors such as skeletal muscle tissue and increases muscle strength and body composition. It has no androgenic activity on nonskeletal muscle tissue. However, it does not cause the overgrowth or oversize of theprostate gland and other sexual organs. MK-2866 is not a steroid, analog of steroid, prohormone or an isomer. It is a part or recent addition to the class of SARM and does not affect the cardiovascular system.

MK-2866The product that is sold in the market is mostly in 50 mg and in BPA-free bottles. Scientists and other professionals buy MK-2866 for research or experimentation only (tested on lab rats); it must not be used for unsupervised human consumption as the amount is not controlled. However, anyone can buy MK-2866 from researchers or pharmaceutical research companies because it has been tested to be safe in the right dosage. For men it should be 25 mg a day and for women, 12.5 mg a day (though it differs according to customer reviews). It is taken orally once a day and has healing properties. Ostarine is used to treat osteoporosis and muscle wasting or atrophy. These conditions can be hereditary or genetic or because of injury or diseases and others related to cancer, AIDS or HIV.  Muscles are also wasted when there is loss of physical activity because of the patient being bedridden for a long period of time and/or unable to move a limb or the rest of the body. It is also used for recovery after a major surgery or injury.

Bodybuilders and fitness enthusiasts buy MK-2866 to bulk, cut and recomp. Ostarine increases and preserves muscle strength, function and lean body mass (bulking). It also reduces calories or body fat (cutting). Or both increase muscle and lose fat at the same time which is recomping. Athletes use it to improve endurance and strength for training. They take 15 mg a day to reduce risks of injury. However, it is currently banned in sports for being a performance enhancing drug.

There is no need for pre cycle support (or any cycle support) and the slight elevation in serum estradriol levels is normal but for those concerned with slight increase in estrogen, low doses of AI can be taken. It is less expensive than steroids and the recovery time is lower. MK-2866 has high oral bioavailability that is not harmful for the liver and blood pressure (unlike steroids that are toxic to the liver). Overdose can lead to side effects like suppression. It must be used for 8-12 weeks (customers also vary with this as some do not exceed 10). Some have been reported to experience blurred vision, sleep disorders, increase in appetite and thirst and many more during the first couple of weeks but it is temporary. When you buy MK-2866, remember that is should be used properly and it will be more efficient with proper diet and exercise.

MK-2866 is currently undergoing clinical trials and not used for prescriptions and hospitals. It is proposed to be eventually used in prescriptions for the treatment of andropause, cachexia, atrophy, sarcopenia and Hormone or Testorone Replacement Therapy in the future. New versions of Ostarine are not developed andthe current version is not improved any further by GTx today. There is news that GTx constantly holds trials of their products and will collaborate with Merck & Company to produce new SARMS for medical conditions like cancer cachexia in the future.
