IGF-1 LR3

IGF-1 LR3, also published as Long R3 IGF-1 and LR3-IGF-1, is catalogued here as: Long-acting IGF-1 analogue. Long R3 IGF-1 is a modified IGF-1 analogue. Findings for native IGF-1 are not automatically findings for the LR3 molecule. A modified version of IGF-1, a growth-related signalling molecule. Evidence specific to the LR3 version remains under review.

A reviewed evidence summary for IGF-1 LR3 is still in progress, so this page does not summarize study findings yet.

When comparing published work, match the exact molecular identity, salt form and strength to the paper. Findings in cell or animal models describe those models only and do not establish outcomes in people. The reconstitution calculator converts vial content and diluent volume into concentration for laboratory preparation.
