IGF-1 LR3 Purity and CoA UK
Peptaro Research Team
IGF-1 LR3 is a large protein-scale analogue of about 83 residues, so its certificate needs different reading from a short peptide. Batch UKPL-449 records 98.134% purity and a mass of 9113.0.

Why a 9 kDa analogue is hard to certify
At around nine thousand daltons, IGF-1 LR3 has multiple disulfide bonds, and misfolded variants can have the same mass as the correct one. A mass match shows the sequence is right but not that the folding is. The record gives 1.08mg against a 1mg label claim and an analysis date of 06/03/2026, and it names no laboratory. We therefore describe it as certificate-stated and recommend buyers weigh that. Supplied for in-vitro laboratory research only, not for human or veterinary use.
Published research on IGF-1 LR3 long R3 insulin-like growth factor is indexed on PubMed.

Frequently asked questions
Does a mass match prove correct folding?
No. Misfolded isomers can share the mass. Folding needs a separate assay.
What does the record show?
98.134% purity, 1.08mg against a 1mg label claim and a mass of 9113.0.
Is the lab named?
No, so we do not describe the figures as independent.
Is it for human use?
No. In-vitro research only.
