IGF-1 LR3 (Insulin-Like Growth Factor 1 Long Arg3) is a recombinant analog of IGF-1, a naturally occurring hormone structurally similar to insulin. IGF-1 is the primary mediator of growth hormone�s anabolic effects, promoting cellular growth, repair, and regeneration throughout the body. The �LR3� version features a modified structure� specifically, an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus�making it more stable, less prone to binding with IGF-binding proteins, and up to 3� more potent than native IGF-1. Its molecular weight is approximately 9.1 kDa, and the sequence includes 83 amino
