Overview
What is IGF-LR3?
IGF-LR3 is a modified form of insulin-like growth factor 1 designed to resist binding proteins, extending its active window considerably compared with native IGF-1.
Mechanism
How it works
IGF-1 signaling drives cellular growth and protein synthesis downstream of growth hormone. The LR3 modification reduces binding protein sequestration, so a greater proportion remains available at receptors.
