Next lot
Be told when the next tested lot of IGF-1 LR3 is released: the certificate link the moment it posts, and a 48-hour early window with 5% off that lot. One message per lot, nothing else.
Overview
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified IGF-1 with an arginine substitution at position 3 and a 13-amino acid N-terminal extension. Modified form of IGF-1 with reduced IGF binding protein affinity and extended half-life.
Published Research
Published literature has examined IGF-1 LR3 across multiple research contexts:
- Reduced IGFBP binding resulting in increased bioavailability in research models
- IGF-1 receptor activation and downstream PI3K/Akt signaling
- Cell proliferation and differentiation pathway studies
- Myogenic and metabolic research biomarker analysis
