Overview
IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic analog of human IGF-1 engineered for extended stability and enhanced activity in research applications. With modifications that increase half-life and reduce binding to IGF-binding proteins, IGF-1 LR3 is widely used in laboratory studies investigating cellular growth, repair, and signaling pathways. This compound is provided strictly for research use only and is not intended for human consumption, medical, or diagnostic purposes.

Research Focus
In preclinical and laboratory settings, IGF-1 LR3 has been studied in relation to:

• Cell growth & proliferation – investigating mechanisms of muscle, tissue, and cellular development.

• Protein synthesis – exploring IGF-mediated pathways in anabolic processes.

• Cell survival signaling – examining its influence on anti-apoptotic pathways.

• Metabolic studies – analyzing its interaction with insulin-like receptors and glucose regulation at the cellular level.
