About this compound
IGF-1 LR3 1 mg – Long-Acting Insulin-Like Growth Factor Peptide
- Composition: 1 mg IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3)
- Category: Peptide
- Form: Vial with lyophilized powder
What is IGF-1 LR3?
IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic analogue of human IGF-1, engineered for greater biological stability and potency.
By replacing the amino acid arginine at position 3 and extending the sequence by 13 additional amino acids, IGF-1 LR3 achieves a prolonged half-life of 20–30 hours—compared to only a few minutes for natural IGF-1.
This allows for sustained activation of IGF-1 receptors, making IGF-1 LR3 a key research peptide in studies of muscle growth, cellular regeneration, and metabolic regulation.
Ideal for growth, regeneration, and insulin-like signaling research.
Key Research Findings
Muscle & Tissue Growth: Activates satellite cells and stimulates protein synthesis.
Cellular Regeneration: Supports the repair of muscle, nerve, and connective tissue.
Enhanced Nutrient Utilization: Promotes glucose uptake and amino acid transport into cells.
Extended Half-Life: Maintains receptor activity for up to 30 hours for prolonged biological effects.
Storage Instructions
- Store at 2–8 °C (36–46 °F)
- Protect from light and moisture
- Do not freeze
- Avoid repeated temperature fluctuations
Why Choose IGF-1 LR3?
IGF-1 LR3 is one of the most extensively researched growth-promoting peptides, known for its prolonged half-life, potent anabolic signaling, and regenerative properties.
Its applications span metabolic, muscular, and cellular growth research, making it a core compound for scientists studying tissue repair and performance biology.
Order IGF-1 LR3 1 mg and take your research on cellular growth and regeneration to the next level.
