Not FDA approvedIGF-1 LR3
IGF-1 LR3 is a modified insulin-like growth factor-I analog. Researchers examine how altered binding-protein interactions change biological activity, including blood-glucose responses in experimental models.
Evidence in this guide: Animal comparisons of IGF variants; LR3 differs from native IGF-I and prescription mecasermin.

IGF-1 DES is the shortened Des(1–3) form of IGF-I. Studies compare its biological effects with native IGF-I and other analogs, including their effects on blood glucose.
Evidence in this guide: Animal analog-comparison studies; DES and LR3 are separate molecules.
