What is IGF-1 LR3?

IGF-1 LR3 is a synthetic analog of naturally occurring insulin-like growth factor-1 (IGF-1), modified to include an additional 13 amino acids and a substitution at position 3 (arginine). These modifications significantly reduce its binding to IGF-binding proteins, resulting in increased bioavailability and a longer half-life.

This allows IGF-1 LR3 to remain active in the body for extended periods, making it a valuable tool for studying sustained growth factor activity.

Mechanism of Action

IGF-1 LR3 binds to IGF-1 receptors (IGF-1R) on the surface of cells, activating intracellular signaling pathways that promote growth, proliferation, and repair.

Key biological effects include:

• Activation of IGF-1 receptors
• Increased protein synthesis
• Enhanced cellular proliferation
• Promotion of muscle cell growth (hyperplasia and hypertrophy)
• Improved nutrient uptake and utilization

Unlike standard IGF-1, the LR3 variant maintains activity for a significantly longer duration, allowing researchers to study prolonged signaling effects.

IGF-1 LR3 vs Standard IGF-1

IGF-1 LR3 offers several advantages over regular IGF-1:

• IGF-1 LR3 – Longer half-life, reduced binding to IGF-binding proteins, increased bioavailability
• Standard IGF-1 – Shorter duration, more tightly regulated by binding proteins

This makes IGF-1 LR3 more suitable for long-term and continuous research applications.
