IGF-1 LR3 1mg

IGF-1 LR3 (Insulin-Like Growth Factor 1 Long Arginine 3) is a synthetic peptide analog of human IGF-1 designed with structural modifications, including a 13-amino-acid N-terminal extension and an arginine substitution at position 3, enhancing receptor affinity and significantly prolonging biological half-life compared to native IGF-1. This extension reduces binding to IGF-binding proteins, allowing IGF-1 LR3 to remain active in biological systems up to 120 times longer, thereby potentiating anabolic and regenerative signaling.
