IGF-1 LR3 is a synthetic analog of insulin-like growth factor-1 (IGF-1), engineered for enhanced stability and prolonged activity in research environments. Structural modifications, including an arginine substitution and extended peptide chain, distinguish it from native IGF-1 and make it a valuable compound for cellular growth and signaling studies.
