IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a synthetic analog of human IGF-1 engineered for extended stability and enhanced receptor binding. This version includes an acetic acid buffer (0.6% AA) designed to help stabilize the peptide after reconstitution versus using bacteriostatic water (BAC-water), which some anecdotal sources claim may lead to more rapid degradation. Supplied as a highly pure, lyophilized powder plus acetic acid buffering agent. For laboratory research use only — not for human or veterinary applications.

Stabilization & Reconstitution Notes
-
Acetic Acid Buffer (0.6% AA): Used to reconstitute IGF-1 LR3 to help maintain solution stability, prevent peptide “sticking” to glass, and slow degradation. Many users report that IGF-1 LR3 solutions in AA remain stable for significantly longer periods (several weeks or more) compared to those reconstituted in BAC water.
