IGF-1 LR3 is a synthetic, extended analog of native IGF-1 designed for enhanced stability and reduced affinity for IGF-binding proteins in experimental systems. This modified peptide contains an additional 13 amino acids at the N-terminus and a substitution of arginine for glutamic acid at position 3, resulting in a significantly prolonged half-life in preclinical research models.
