Corex Vitality™ supplies Cagrilintide as a lyophilised research peptide in vials, and as a solution in a research pen, for in-vitro laboratory work in the UK. This page explains what Cagrilintide is, what the published receptor research covers, what to check before you buy, and our current sizes, prices and Certificate of Analysis (COA).

At a glance

What is Cagrilintide?

Cagrilintide is a synthetic analogue of amylin, a peptide hormone made in the pancreas. Native amylin readily forms amyloid fibrils, and the discovery paper describes the chemistry used to make a stable, lipidated analogue [1].

Cagrilintide acts at two related receptor types: the amylin receptors (AMY1R, AMY2R and AMY3R) and the calcitonin receptor (CTR) [2][3]. An amylin receptor is a calcitonin receptor paired with a receptor activity-modifying protein (RAMP) [4]. Compounds that act at both are described in the literature as dual amylin and calcitonin receptor agonists (DACRAs) [3].

What has been studied? (preclinical receptor research only)

• Molecular design. The discovery paper describes the structure-activity work that led from native amylin to Cagrilintide, a stable and lipidated analogue [1].
• Receptor structures. Cryo-electron microscopy (cryo-EM) structures show Cagrilintide bound to active, Gs-coupled amylin receptors (AMY1R, AMY2R and AMY3R) and to the calcitonin receptor, and compare how the peptide engages each one [2].
• How one peptide activates two receptor types. A second structural study reports that Cagrilintide adopts a similar “bypass” binding mode in AMY1R and CTR. It points to an E14–R17 salt bridge inside the peptide and a phenylalanine at position 23 as key features [3].
• The amylin 1 receptor. A cryo-EM study of AMY1R (calcitonin receptor plus RAMP1) shows how different peptides can sit in the same receptor with different shapes in their middle section [4].

This is laboratory and receptor research. It cannot be applied to people. Corex Vitality™ makes no claim about any effect of Cagrilintide in the body.

What to check before you buy Cagrilintide in the UK

1. The compound named on the COA. Check that the product page and the COA name the same compound and the same size.
2. An open, size-matched COA. Our Cagrilintide COA covers the 10mg batch (LDA22160972), the same size as the vial in stock. There is no separate 2mg or 5mg COA.
3. The QR check. Scan the QR code on the Lingda COA to see the laboratory’s own record. Our guide shows how to verify a peptide COA.
4. Claims that match the COA. Our Cagrilintide COA reports HPLC purity and quantity, heavy metals, endotoxin and sterility. It does not include a molecular-mass identity test.
5. Purity vs content. HPLC purity is not net peptide content. See HPLC purity vs net peptide content.
6. Research-only selling and UK business details. Look for a company number, a registered address, an ICO registration, and no human-use instructions.

What our Cagrilintide COA shows

The report is LDA22160972 from Lingda Laboratory. It was tested on 2 September 2026 and issued on 3 September 2026. The laboratory was commissioned by the manufacturer or supplier. The COA is published exactly as the laboratory issued it.
