Molecular weight ≈9111 g/mol

This structure includes modifications that a residue-by-residue view can't show accurately, so we describe it in words instead.

IGF-1 LR3 is an 83-residue analog of insulin-like growth factor 1 with a 13-residue N-terminal extension and an arginine at position 3, which lowers binding to IGF-binding proteins in assay systems.

Frequently asked questions

What is IGF-1 LR3?

IGF-1 LR3 is an 83-residue analog of insulin-like growth factor 1 with a 13-residue N-terminal extension and an arginine at position 3, which lowers binding to IGF-binding proteins in assay systems.

What is the amino acid sequence of IGF-1 LR3?

83-residue recombinant IGF-1 analog (N-terminal extension, Glu3→Arg); full sequence on the certificate.

How should IGF-1 LR3 be stored?

Store unopened vials of freeze-dried powder at −20 °C, protected from light and moisture. Short periods at room temperature in transit do not affect lyophilised material. Let a vial reach room temperature before opening so condensation does not form inside.

How is IGF-1 LR3 tested?

Each lot is sent to an independent third-party laboratory for analysis, and the certificate of analysis is published on our Lab Results page when the lot is released. Until then, the product shows "COA pending".

How does IGF-1 LR3 ship?

We ship within the United States only, by FedEx 2Day, cold-packed and tracked, with delivery expected by 5 p.m. on the scheduled delivery date. Orders placed before 10 a.m. PT (1 p.m. ET) on business days ship the same day. No weekend dispatch. Shipping is free on peptide orders over $250.
