Tiers name what a vendor publishes, not a verdict on any product's purity or quality.
Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do).
Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site.
Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score.
Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
Cheapest per vial size
$/mg usually drops as vials get bigger, so the cheapest $/mg overall is often a big vial. Compare inside the size you would actually order. The size with the most listings is 10 mg.
Cagrilintide is an amylin analog researched in laboratory settings for its potential role in metabolic and appetite-regulating pathways. This peptide is studied primarily for its effects on satiety signaling and energy balance in preclinical models.
Evidence brief
Cagrilintide is an investigational long-acting amylin analogue studied for weight management; the main standalone human data is a phase 2, dose-finding randomized trial.
Investigational — not approved. As CagriSema (with semaglutide), Novo Nordisk filed an FDA application in Dec 2025; a decision is expected around late 2026. Research use only — not medical advice.

Cagrilintide is an investigational long-acting amylin analogue studied for weight management; the main standalone human data is a phase 2, dose-finding randomized trial.
"Are peptides safe?" has no single answer. The compounds sold as research peptides sit at very different points on the evidence scale, from large randomized human trials for a few to animal-only data for many.
Source-linked reference figures with the population and study context alongside each amount. Study arms are not a starting dose, titration schedule, or personal treatment plan. Label records refer to the named approved medicine, not vendor products.

Research use only — this reports what an FDA label, a peer-reviewed study or a clinical-trial registry entry published, tied to its species and study context. A trial-registry figure is what a sponsor registered, not a peer-reviewed result. It is not medical advice, not a recommendation to use, and no dose here is generated by pepmg. Any dosing decision is for a qualified professional. Animal-study amounts do not establish a human dose.

Per-mg prices for Cagrilintide vary significantly between vendors due to differences in synthesis scale, purity verification, and batch consistency. Comparing prices helps researchers identify cost-effective sources while ensuring the compound meets their research-grade specifications.
▸ Reading the COA
For Cagrilintide, a Certificate of Analysis should confirm identity via mass spectrometry and purity by HPLC, typically above 98%. Check for common adulterants like residual solvents or truncated peptide fragments, and verify that the stated mass matches the actual fill weight to avoid under-filling.
▸ FAQ
How should Cagrilintide be stored for research purposes?
Store lyophilized Cagrilintide in a freezer at -20°C, protected from light and moisture, to maintain stability. Reconstituted solutions should be kept refrigerated and used promptly to avoid degradation.
What is a Certificate of Analysis (COA) and why is it important?
A COA is a document from the vendor or third-party lab that verifies the peptide's identity, purity, and concentration. It is crucial for confirming that the compound meets research-grade standards and is free from contaminants.
Why do prices for Cagrilintide differ so much between suppliers?
Price differences stem from factors like synthesis methods, scale of production, quality control testing, and purity levels. Higher-priced vendors often invest in rigorous third-party analytics, while lower prices may reflect less stringent processing.
All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label, a peer-reviewed study or a clinical-trial registry entry has published a dose, pepmg reports it with the source named and the tier labeled (a registry figure is marked trial registry, not peer-reviewed), because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
