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
