IGF-1 LR3 1mg (Insulin-Like Growth Factor-1 Long R3) is a synthetic analog of human IGF-1 that has been modified to remain active in the body significantly longer than naturally occurring IGF-1. The peptide contains an arginine substitution at position 3 and a 13-amino-acid extension, which reduces binding to IGF-binding proteins and extends its biological activity.
