Ostarine

Ostarine, also known as MK-2866, is a selective androgen receptor modulator (SARM) that has gained popularity for its potential benefits in muscle growth and fat loss. Although not FDA-approved, it is present in some supplements.

It’s currently under investigation for its potential to treat various muscle wasting diseases such as osteoporosis, cancer, and hypogonadism. Despite the FDA not having approved Ostarine, athletes and bodybuilding enthusiasts frequently use it for its alleged athletic benefits.

Ostarine works by binding to androgen receptors in key skeletal muscle tissues throughout the body, triggering muscle growth. While this mechanism is similar to how steroids work, Ostarine is not a steroid. Instead, it’s a SARM that can increase muscle mass while decreasing body fat.

However, like any other drug, Ostarine does have potential side effects. Some users may experience acne, skin irritation, rashes, headaches, and nausea. Changes in brain chemistry are also possible, which can lead to mood swings and menstrual cycle changes.

Despite these potential side effects, some studies indicate that Ostarine may help increase lean body mass and decrease fat mass. However, given the potential risks, it’s crucial to consult with a healthcare professional before starting any new supplement regimen.
