IGF-1 LR3: frequently asked questions

What is IGF-1 LR3?

IGF-1 LR3 is a modified version of IGF-1 with a 13-amino acid extension that prevents binding to IGF-binding proteins, resulting in enhanced bioactivity and a longer half-life.

What is IGF-1 LR3 researched for?

Published preclinical research has examined IGF-1 LR3 in cell-proliferation, myocyte-pathway, and PI3K/Akt signalling studies. The extended half-life makes it useful in protocols requiring sustained in-vitro receptor engagement.

What purity does Peptify supply?

Peptify IGF-1 LR3 is 99%+ HPLC-verified, with a batch-specific Janoshik Analytical Certificate of Analysis downloadable from the product page.
