SARM GW, also known as Cardarine, is a type of selective androgen receptor modulator that is popular for its potential benefits in fat loss, endurance enhancement, and improvement in overall strength and physical performance. It works by activating PPAR-delta receptors, resulting in the stimulation of fatty acid oxidation and improvement of insulin sensitivity. Although SARM GW is not approved for human consumption, it is sold as a research chemical and is used by bodybuilders and athletes to achieve their fitness objectives. Proper consultation with a healthcare professional is necessary before using SARM GW due to its potential side effects and uncertain safety profile.
