What IGF-1 LR3 is

IGF-1 LR3 is a tweaked, longer-lasting version of a natural growth factor called insulin-like growth factor 1. It is supplied as an analytical-grade reference material for laboratory research.

What it does — in plain terms

IGF-1 is one of the body's main 'grow and multiply' signals for cells. The 'LR3' version is engineered to stay active much longer in lab conditions, which makes it convenient for experiments. In cell-culture research it's used to study how cells grow, divide, and respond to growth signals — it's a common tool for keeping cells growing steadily in a dish.

Here's where IGF-1 LR3 actually shows up in the published research:
