GLP-3R

GLP-3R is the store’s research listing for the peptide indexed under the code LY3437943 and characterised in receptor assays as a single molecule with agonist activity at three receptors: GIP, GLP-1 and glucagon. Its backbone is a 39-residue chain derived from the GIP sequence, modified with non-coded amino acids and a fatty-acid side chain. This page covers the lyophilized vial format in 10 mg, 15 mg and 30 mg sizes, and the certificate for each size’s current lot is posted in the COA box above. It is sold as a reference material for laboratory research only.

Batch documentation

Each strength has its own Horizon Analytical report in the COA box, produced by UPLC with mass spectrometry. The lots posted today are:

• 10 mg: lot RRL-8032676-P, 99.5% purity, 9.92 mg measured against the 10 mg label, analysed 27 Jun 2026
• 15 mg: lot RRL-1764133-P, 99.44% purity, 15.05 mg measured, analysed 27 Jun 2026
• 30 mg: lot RRL-9041738-P, 99.16% purity, 29.8 mg measured, card dated 05 Jun 2026

Every certificate lists CAS 2381089-83-2, the formula, and PubChem CID 171390338, and each lot has a separate endotoxin report (the “-E” lot suffix). To tie a certificate to the vial in hand, match the lot printed on the label to the lot on the PDF. Then confirm the report through the lab’s own lookup at horizonanalytical.com or the QR code on the certificate. Our guide to verifying a peptide COA walks through each step, and the full archive by product and batch lives in the Revitalized Research COA library. Batch certificates are posted when available.

Storage and handling

Lyophilized peptide keeps best sealed, dry, cold and away from light. The compound’s long lipidated chain makes it sensitive to moisture and repeated temperature cycling, so keep the vial closed until the day of use and log the receipt date beside the lot number. Reconstitution water is not included; the lab chooses its own diluent, such as reconstitution solution, sold separately. Handle under your institution’s protocols with gloves and eye protection. Our notes on peptide storage basics for research labs cover temperature, light and aliquoting.

Frequently asked questions

What is GLP-3R?

GLP-3R is our research listing for LY3437943, a peptide studied in the literature as a triple GLP-1/GIP/glucagon receptor agonist. It is supplied strictly for laboratory research use.

What sizes does GLP-3R come in?

GLP-3R is available in 10mg, 15mg, and 30mg vials, each with its own batch COA published on the COA page.

Is GLP-3R third-party tested?

The lots currently shown on this page (10 mg RRL-8032676-P, 15 mg RRL-1764133-P, 30 mg RRL-9041738-P) were analysed by Horizon Analytical, an outside laboratory, by UPLC-MS for identity, content and purity, with a separate endotoxin report per lot. Batch certificates are posted when available; match the lot on your vial label to the certificate.

How does the GLP-3R vial differ from the GLP-3 pen listing?

Both listings are the same compound (LY3437943). The vial is dry lyophilized powder that the lab reconstitutes itself, offered in 10, 15 and 30 mg; the GLP-3 (Pen) listing is a pre-filled pen format in 10 and 30 mg fills with its own handling notes.
