IGF-1 LR3
Key Takeaways: IGF-1 LR3
IGF-1 LR3 is a Other peptide primarily researched for:
- Superior muscle growth (Hyperplasia)
- Long-acting half-life (20-30 hours)
- Improved metabolic rate and fat loss
Research Profile
IGF-1 LR3 (Long Arginine 3 IGF-1) is a synthetic, long-acting analog of the human hormone Insulin-like Growth Factor 1. It is designed to be significantly more potent and stable than natural IGF-1.
Extended Half-Life
By modifying the peptide structure, IGF-1 LR3 avoids being neutralized by IGF-binding proteins in the blood. This extends its activity from a few minutes to over 24 hours, allowing it to exert powerful anabolic effects on muscle and organ tissue throughout the day.
Hyperplasia vs Hypertrophy
Researchers are particularly interested in IGF-1 LR3 because it can stimulate hyperplasia—the creation of new muscle cells—rather than just hypertrophy (making existing cells larger). This makes it a primary focus for research into muscle wasting and regenerative medicine.
