IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1)

IGF-1 LR3 is a modified version of insulin-like growth factor-1 (IGF-1) with an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus. These modifications reduce binding to IGF binding proteins, resulting in a significantly longer half-life compared to native IGF-1. It is one of the more potent growth factor peptides studied in laboratory settings.
