Ligandrol, also known as LGD-4033, is a selective androgen receptor modulator (SARM) that is popular among bodybuilders and athletes for its potential to increase muscle mass and strength. It works by binding to androgen receptors in the body, specifically targeting muscle and bone tissue.

Ligandrol is believed to have similar effects to testosterone but without the same level of side effects. However, like other SARMs, it is not approved for human use and its long-term effects are not well understood. Side effects of Ligandrol can include testosterone suppression, liver toxicity, and changes in cholesterol levels.

It’s important to note that the use of Ligandrol and other SARMs is controversial and can pose health risks. It’s always advisable to consult with a healthcare professional before considering the use of SARMs or any other performance-enhancing substances.
