IGF-1 LR3, or insulin-like growth factor-1 long arginine 3, is a synthetic peptide variant designed with extended half-life through structural modification. Research explores its roles in cell division, proliferation, and signaling pathways due to reduced binding affinity to IGF-binding proteins. IGF-1 LR3 remains under investigation for research use only.
