IGF-1 LR3 1mg – High-Purity Research Peptide
IGF-1 LR3 (Insulin-like Growth Factor 1, Long Arg3) is a synthetic analogue of IGF-1 modified to reduce binding affinity to IGF-binding proteins, resulting in an extended circulation profile compared to native IGF-1.
Supplied in lyophilised (freeze-dried) form to support stability and handling, this compound is verified at >99.1% purity (HPLC-tested) and provided with full Certificates of Analysis (COAs) for batch-specific verification and traceability.
What is IGF-1 LR3?
IGF-1 LR3 is a laboratory-engineered peptide designed to extend the activity profile of native IGF-1 through structural modification. In controlled research environments, it is utilised as a model compound in studies involving IGF-related pathways, peptide structure, and receptor interaction systems.
