IGF-1 LR3 Peptide 1mg
IGF-1 LR3 is a recombinant long-acting analog of insulin-like growth factor-1, a single-chain polypeptide growth factor. It carries an arginine substitution at position three and a 13-amino-acid N-terminal extension, modifications that reduce binding to IGF-binding proteins and extend IGF-1 receptor engagement in cell-culture and preclinical model systems. It is studied in work on cell proliferation, protein synthesis signaling, and metabolic pathway regulation.
RegenX Peptides supplies IGF-1 LR3 as a 1mg lyophilized multi-dose vial. Every batch is assayed by an independent laboratory, and the certificate for the current lot is published on the lab results page so purity and identity can be reviewed before purchase. Orders ship from Florida and California within 24 hours. Sold strictly for research use only; not for human or animal consumption.
What Is IGF-1 LR3 Peptide?
IGF-1 LR3 is a synthetic analog of human insulin-like growth factor-1 in which the first three amino acids are removed and an arginine added at position 3. This modification greatly extends its half-life and receptor affinity. In research settings, IGF-1 LR3 is used to examine IGF-1 receptor dynamics, anabolic signaling, and metabolic regulation with greater temporal control than native IGF-1.
