IGF-1 LR3 (1mg) is a long-acting synthetic peptide variant of Insulin-like Growth Factor 1. It promotes muscle growth, enhances recovery, and supports fat loss by increasing protein synthesis and cell regeneration. With a longer half-life than standard IGF-1, LR3 stays active in the body for up to 20–30 hours, making it a popular choice for athletes and bodybuilders aiming to optimise performance and physique.
