IGF-1 LR3 1mg | Insulin-Like Growth Factor-1 Long R3 | Cellular Growth & Regeneration Research 

IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic analog of human IGF-1, a potent growth factor peptide that regulates cell proliferation, differentiation, and survival.

At West Lab Chemicals, we provide IGF-1 LR3 1mg (Research Grade) with ≥99% purity (HPLC & MS verified), produced in GMP-certified laboratories to ensure biological consistency, sterility, and stability.

This peptide is widely used in cell culture, muscle growth, and metabolic pathway research, where it supports cellular repair, tissue regeneration, and anabolic signaling studies.

What is IGF-1 LR3?

IGF-1 LR3 is a modified version of natural human IGF-1 (Insulin-Like Growth Factor-1) that has an extended half-life and enhanced biological potency.

The “LR3” (Long Arg3) modification replaces Arginine at position 3 and extends the amino acid chain by 13 residues, significantly reducing its binding affinity to IGF-binding proteins (IGFBPs).

As a result, IGF-1 LR3 remains active in plasma for a longer duration, allowing researchers to explore sustained IGF signaling, anabolic response, and cellular recovery with higher efficiency.

Mechanism of Action

• Binds to IGF-1 receptors (IGF-1R) on muscle, nerve, and epithelial cells.

• Activates PI3K/Akt and MAPK pathways, promoting cellular growth.

• Enhances protein synthesis and glucose utilization.

• Supports muscle hypertrophy, tissue repair, and cell survival.

• Modulates insulin sensitivity and metabolic activity in research systems.
