IGF1-LR3

What Is IGF-1 LR3?

IGF-1 LR3 is a synthetic peptide derived from the naturally occurring Insulin-like Growth Factor 1 (IGF-1), which is responsible for promoting cell growth, muscle development, and recovery.

The LR3 version (Long R3) has been structurally modified by replacing the arginine at position 3 and extending the peptide chain by 13 additional amino acids. These modifications prevent binding to IGF-binding proteins (IGFBPs), allowing IGF-1 LR3 to remain active in the body up to 20–30 hours, compared to just 20 minutes for natural IGF-1.

This extended half-life makes IGF-1 LR3 one of the most effective peptides for long-term anabolic and regenerative research.

Key Benefits Observed in Research

• Stimulates Muscle Growth: Promotes protein synthesis and muscle fiber enlargement.

• Enhances Recovery: Supports faster repair of muscle and connective tissues post-training.

• Promotes Cell Regeneration: Triggers the proliferation of muscle satellite cells.

• Increases Fat Metabolism: Enhances nutrient partitioning and energy utilization.

• Improves Performance & Strength: Supports endurance and long-term athletic capacity.

Because of these effects, IGF-1 LR3 is frequently studied in muscle repair, anti-aging, and regenerative medicine research.
