🧬 What is IGF-1 LR3?
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified version of human IGF-1, designed to enhance anabolic effects and resist IGF-binding protein inhibition. This peptide contains a 13-amino acid N-terminal extension and an arginine substitution at position 3, which significantly prolong its half-life and increase receptor affinity.
It is widely used in research involving muscle hypertrophy, cell proliferation, and tissue repair, particularly in models of aging, trauma, or metabolic stress.
