Mechanism	IGF-1 LR3 is a modified version of insulin-like growth factor-1 (IGF-1) with a longer half-life. The modifications make it more potent and prevent binding to IGF-binding proteins, allowing it to remain active in the body longer. It promotes muscle growth and fat loss.	Follistatin is a protein that inhibits myostatin, a negative regulator of muscle growth. By blocking myostatin, follistatin allows for increased muscle mass and strength.
