What is Retatrutide + Cagrilintide?
This blend pairs retatrutide, a triple agonist at the GIP, GLP-1 and glucagon receptors, with cagrilintide, a long-acting amylin analogue, co-lyophilized in one lot-matched vial. The two are combined in research that looks at incretin and amylin pathways together rather than in separate preparations. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.
What is Retatrutide + Cagrilintide studied for?
- Combined incretin and amylin pathway studies
- Receptor occupancy work across four receptor systems
- Energy-balance and gastric-emptying models
- Comparison against each component alone
All applications above are in-vitro or preclinical research contexts. Retatrutide + Cagrilintide is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot RET-2609-X show?
Every lot of Retatrutide + Cagrilintide is tested by an independent US laboratory before it is listed. The report for lot RET-2609-X is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot RET-2609-X result |
|---|---|---|
| Identity | LC-MS | Matches the calculated mass for the sequence |
| Purity | HPLC-UV, 220 nm | 99.0% |
| Net peptide content | Amino acid analysis | Stated per vial on the certificate |
| Endotoxin | LAL, chromogenic | < 0.5 EU/mg |
| Sterility | USP <71> | Pass |
How is Retatrutide + Cagrilintide handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within the 28-day window on the certificate. The reconstitution guide covers volumes and syringe units and the concentration table gives the numbers for this vial.
Frequently asked questions
Why are these two combined in one vial?
So both are drawn from a single reconstitution at a fixed ratio. Where an independent ratio is needed, the separate vials are the better choice.
How is a blend certificate read?
Purity is reported per component with each main peak integrated against the total, and identity needs both observed masses. The certificate guide covers this.
Is Retatrutide + Cagrilintide for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
