IGF-1 LR3 is an 83-amino acid modified form of IGF-1 with an arginine substitution at position 3 and a 13-amino acid N-terminal extension. These modifications dramatically reduce binding to IGF binding proteins (IGFBPs), resulting in higher free IGF-1 levels and enhanced IGF-1R activation for anabolic signalling via PI3K/Akt and Ras/MAPK pathways.
Clinical Benefits
- Reduced IGFBP binding for greater free IGF-1
- Extended biological half-life vs native IGF-1
- Supports anabolic and tissue growth pathways
- Enhanced potency through structural modification
