IGF-1 LR3 is a modified insulin-like growth factor 1 analogue with an extended activity profile compared with native IGF-1. It is primarily associated with experimental and research applications.

The Odin Pharmaceuticals listing specifies “1” but does not identify whether this represents mg, another unit, or a specific formulation. The product label should be checked before stating a numerical strength.

Because IGF-1 signalling can influence glucose metabolism and cellular growth pathways, accurate product characterization is important. GORoids should verify labeling, storage, formulation, and regulatory information.
