IGF1-LR3

IGF1-LR3 is a synthetic analogue of insulin-like growth factor-1 that researchers engineer for enhanced biological activity and an extended half-life. Laboratories use this peptide exclusively for scientific research and experimental applications. Manufacturers supply IGF1-LR3 as a lyophilized powder to support stability, handling, and storage efficiency. Independent HPLC and mass spectrometry testing verify ≥98% purity for every batch.

The LR3 (Long Arginine 3) modification reduces protein binding compared to standard IGF-1, allowing longer receptor interaction during controlled in vitro and in vivo studies. Researchers commonly investigate IGF1-LR3 for its role in cellular proliferation, differentiation, metabolic signaling, and anabolic research pathways.

Key Features:

High Purity — Independent HPLC and mass spectrometry analysis verify ≥98% purity

Enhanced Stability — Manufacturers provide a lyophilized format for convenient reconstitution with

sterile water or acetic acid

Extended Bioactivity — The LR3 modification minimizes protein binding and supports prolonged activity in research settings

Research Use Only — Laboratories use this peptide strictly for research purposes only; manufacturers do not market it for human or veterinary use, dietary supplements, or clinical applications

Secure Packaging — Vacuum-sealed vials with desiccant support optimal transport conditions and long-term storage integrity.
