IGF-LR3

IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a synthetic 83-amino acid analog of human IGF-1. Modified with an arginine substitution at position 3 and a 13-amino acid N-terminal extension, it exhibits significantly reduced binding to IGF-binding proteins (IGFBPs), leading to an increased half-life and enhanced potency for studying cellular growth, protein synthesis, and muscle hypertrophy.

Every batch undergoes rigorous independent, third-party high-performance liquid chromatography (HPLC) and mass spectrometry (MS) testing to guarantee unparalleled purity, identity, and exact concentration.
