Ostarine, also known as MK-2866, is a selective androgen receptor modulator (SARM). SARMs are a type of drug that binds to androgen receptors in the body, but only in certain tissues, such as muscle and bone. This makes them a potential alternative to anabolic steroids, which bind to androgen receptors in all tissues, including the prostate and liver.

Ostarine has been shown to be effective in increasing muscle mass and strength in animal studies and human clinical trials. In one study, men with low testosterone levels who took Ostarine for 12 weeks gained an average of 1.5 kilograms of muscle mass and 2.3 kilograms of lean body mass. They also experienced a significant increase in strength, with an average increase of 10% on the bench press and 12% on the squat.

Ostarine is also being investigated for its potential to treat osteoporosis. In one study, women with osteoporosis who took Ostarine for 12 months experienced a significant increase in bone mineral density. They also had a lower risk of bone fractures.

While Ostarine has shown promise in clinical trials, it is important to note that it is still under development and has not been approved by the FDA for any medical use. It is also important to be aware of the potential side effects of Ostarine, which can include liver damage, heart disease, and prostate cancer.

Here are some additional things to know about Ostarine:

It is a research chemical and is not currently approved for human use.
It is often sold as a dietary supplement, but there is no guarantee of its quality or purity.
It can have side effects, including liver damage, heart disease, and prostate cancer.
It is banned by the World Anti-Doping Agency (WADA) and the National Collegiate Athletic Association (NCAA).

If you are considering using Ostarine, it is important to talk to your doctor first. They can help you assess the risks and benefits of this compound and make sure it is right for you.
