IGF-1 LR3 for Sale
IGF-1 LR3 (Long Arginine 3 Insulin-like Growth Factor-1) is a synthetic analog of native IGF-1 engineered for enhanced research applications. This research peptide incorporates an arginine substitution at position three and a 13-amino acid N-terminal extension, resulting in significantly reduced IGFBP binding affinity and extended half-life.
When you buy IGF-1 LR3 from NextGen Peptide, you acquire a premium compound backed by complete analytical documentation. Every vial we sell IGF-1 LR3 with includes a third-party Certificate of Analysis (COA) verifying ≥98% purity through HPLC and mass spectrometry.
Researchers consistently order IGF-1 LR3 online from us because we eliminate sourcing uncertainty. No hidden impurities. No questionable handling. Just verifiable, lab-tested peptide delivered with full chain-of-custody transparency.
IGF-1 LR3 demonstrates markedly reduced binding to insulin-like growth factor binding proteins (IGFBPs) compared to native IGF-1. This property results in enhanced bioavailability and extended receptor activation kinetics, making it uniquely valuable for studying IGF-1 receptor signaling in the absence of binding protein interference.
Why do leading cell biology laboratories purchase IGF-1 LR3 from NextGen Peptide? Each shipment includes endotoxin screening (<1 EU/mg) and complete chromatographic data.

Frequently Asked Questions
Is IGF-1 LR3 approved for human use?
No. This research peptide is exclusively for laboratory and preclinical use. Not for human consumption.
Do you provide COAs before purchase?
Yes. Contact our support team to review COA documentation prior to ordering.
Can I order IGF-1 LR3 online internationally?
Yes, where local regulations permit. Buyers assume full responsibility for compliance with import laws.
How does IGF-1 LR3 differ from native IGF-1?
IGF-1 LR3 has reduced IGFBP binding affinity and extended half-life due to its arginine substitution and N-terminal extension.
How does IGF-1 LR3 differ from IGF-DES?
IGF-1 LR3 has enhanced half-life and reduced IGFBP binding. IGF-DES has reduced IGFBP binding but similar half-life to native IGF-1.
