IGF-1 LR3

Long-acting analogue of insulin-like growth factor 1, widely used as a cell-culture reagent.

What is IGF-1 LR3?

IGF-1 LR3 is a modified form of insulin-like growth factor 1 that binds poorly to IGF-binding proteins, so it stays active much longer. It is a standard supplement in cell-culture media.

It is not an approved medicine, can lower blood sugar, and is prohibited in sport.
