Core Effects

LGD3303 is a highly selective androgen receptor modulator (SARM) that is widely used in muscle growth research, osteoporosis treatment, and muscle atrophy research due to its excellent tissue selectivity and potent anabolic activity .

✅ Powerful muscle growth :

Binds to androgen receptors with high affinity , promoting protein synthesis

8-12 week cycle can increase muscle mass by 5-8kg (combined with resistance training)

✅ Improved bone health :

Increase bone mineral density and reduce the risk of fractures

Stimulate bone formation and improve osteoporosis

✅ High selectivity advantage :

Minimal impact on the prostate , no risk of benign prostatic hyperplasia

Tissue- specific effects , reducing systemic side effects
