IGF-1 LR3 1mg

IGF-1 LR3 is a synthetic long-acting analog of insulin-like growth factor 1 (IGF-1). Through structural modification, the glutamic acid at position 3 is replaced with arginine, with an additional 13 amino acids at the N-terminus, forming an 83-amino acid active molecule. Compared to natural IGF-1 (70 amino acids), its half-life extends to 20-30 hours with approximately threefold increased potency. It binds weakly to IGF-binding proteins, strongly binds to the IGF-1 receptor, and activates the PI3K/Akt and MAPK pathways.
