lr3

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a highly potent, synthetic analog of endogenous IGF-1, specifically engineered for extended biological activity. By incorporating a 13-amino acid N-terminal extension and a substitution of Arginine for Glutamic Acid at position 3, this peptide is designed to bypass IGF-binding proteins (IGFBPs), significantly increasing its half-life and potency. Each 1mg vial is vacuum-sealed and guaranteed at 99% purity, making it an essential tool for researching cellular proliferation, muscle hypertrophy, and glucose transport.
