IGF -1 LR3

IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arg3) is a synthetic peptide hormone and a modified form of natural IGF-1. The “LR3” variant has an extended half-life (around 20–30 hours) due to the substitution of arginine at position 3 and a 13-amino acid extension at the N-terminus. These changes significantly increase its biological activity and stability in the body.
Key Benefits:
Promotes muscle growth and cell repair
Enhances fat metabolism
Stimulates protein synthesis
Supports bone growth and nerve regeneration
How It Works:
IGF-1 LR3 binds to IGF receptors and insulin receptors, mimicking the effects of growth hormone by increasing cellular proliferation and nutrient uptake—especially in muscle tissue.
Common Uses (Research purposes):
Performance enhancement
Anti-aging research
Muscle wasting disorders
