Cagrilintide Reconstitution and Storage: Diluent Volumes, Concentration Table, and Shelf Life
Reviewed by the VendPeptides Editorial Team. Written from product labeling, the batch certificate of analysis and published literature. Last updated September 2026.
Cagrilintide is a long-acting amylin analogue research peptide supplied as a lyophilized powder for laboratory use.
It has been studied in a phase 2 trial for weight management in people with overweight and obesity, as reported in the published literature.
The compound is also known by the code names NN9838, AM833, and as a CagriSema component (CAS 1415456-99-3), and VendPeptides sells it in 5 mg and 10 mg vials as well as 10-vial kits.
This guide covers what Cagrilintide is, Cagrilintide Reconstitution and Storage by vial size, safe laboratory handling, and where to buy it.
What is Cagrilintide Reconstitution and Storage?
Cagrilintide Reconstitution and Storage is the laboratory practice of dissolving the lyophilized peptide in a suitable diluent and keeping the resulting solution under conditions that preserve its integrity for research use.
The compound itself is a long-acting amylin analogue with CAS number 1415456-99-3, also referred to as NN9838, AM833, or a CagriSema component.
For research purposes only. Not for human consumption.
Reconstitution is a concentration calculation: the mass of peptide in the vial divided by the volume of diluent added gives the final concentration in mg/mL.
Cagrilintide Reconstitution and Storage, NN9838 and AM833: are they the same?
Yes. NN9838, AM833, and Cagrilintide are different names for the same long-acting amylin analogue, and CagriSema component is a descriptor used when the compound is discussed alongside a semaglutide combination.
The CAS number 1415456-99-3 is the unambiguous identifier to check against the vial label and the batch certificate of analysis (COA).
For research purposes only. Not for human consumption.
Always defer to the vial label and the batch COA when confirming identity before reconstitution.
What has Cagrilintide Reconstitution and Storage been studied for?
Cagrilintide has been studied in a phase 2 trial for weight management in people with overweight and obesity, as reported by Lau DCW et al. in The Lancet (2021).
That published work describes the research context only; it is not a claim about the product sold here.

Readers should consult the published literature and the batch certificate of analysis (COA) for identity, purity, and handling information.
Cagrilintide Reconstitution and Storage reconstitution and concentration by vial size
Adding 1 mL (1,000 µL) of bacteriostatic water to a 5 mg vial gives 5 mg/mL, and the table below scales that calculation across the strengths sold.
| Vial size | 10-vial kit total | Diluent added | Resulting concentration | µg per µL |
|---|---|---|---|---|
| 5 mg | 50 mg | 1 mL (1,000 µL) | 5 mg/mL | 5 µg/µL |
| 5 mg | 50 mg | 2 mL (2,000 µL) | 2.5 mg/mL | 2.5 µg/µL |
| 10 mg | 100 mg | 1 mL (1,000 µL) | 10 mg/mL | 10 µg/µL |
| 10 mg | 100 mg | 2 mL (2,000 µL) | 5 mg/mL | 5 µg/µL |
| 10 mg | 100 mg | 3 mL (3,000 µL) | 3.33 mg/mL | 3.33 µg/µL |
The vial label and the batch certificate of analysis (COA) take priority over any table when the two disagree.
Cagrilintide Reconstitution and Storage 10mg vial reconstitution
A 10 mg vial reconstituted with 2 mL (2,000 µL) of diluent gives 5 mg/mL, which is 5 µg/µL.
Using 1 mL (1,000 µL) instead gives 10 mg/mL, and using 3 mL (3,000 µL) gives approximately 3.33 mg/mL.
For research purposes only. Not for human consumption.
Record the diluent volume, date, and lot number, and defer to the vial label and batch COA for the official values.
Cagrilintide Reconstitution and Storage 5mg vial reconstitution
A 5 mg vial reconstituted with 1 mL (1,000 µL) of diluent gives 5 mg/mL, which is 5 µg/µL.
Using 2 mL (2,000 µL) gives 2.5 mg/mL, or 2.5 µg/µL, which is often easier to pipette accurately in small volumes.
For research purposes only. Not for human consumption.
Check the batch certificate of analysis (COA) for the actual fill mass before calculating concentration.
How long does reconstituted Cagrilintide Reconstitution and Storage stay stable?
There is no single shelf life that applies to every laboratory; stability depends on diluent, concentration, temperature, and handling.
Lyophilized powder is generally stored frozen and protected from light, while reconstituted solution is typically kept cold and used within a short working window.
For research purposes only. Not for human consumption.
Follow the storage instructions on the vial label and the batch certificate of analysis (COA) rather than a generic rule.
How to handle Cagrilintide Reconstitution and Storage safely in the laboratory
- Put on gloves, a lab coat, and eye protection before opening the vial.
- Work in a clean, designated area and wipe the surface and vial septum with an appropriate disinfectant.
- Let the vial reach the working temperature stated on the label before adding diluent.
- Add the chosen diluent volume slowly down the inside wall of the vial to reduce foaming.
- Swirl gently until the powder is fully dissolved, and do not shake the vial.
- Label the vial with the compound name, concentration, diluent, date, and lot number.
- Store the vial according to the label and the batch certificate of analysis (COA).
Warning: Poor sterile technique or an unlabeled vial can contaminate the preparation and make the material unusable for research, so label every vial immediately and follow the COA storage instructions.
Is Cagrilintide Reconstitution and Storage the same as Semaglutide?
No. Cagrilintide is a long-acting amylin analogue, while Semaglutide is a GLP-1 receptor agonist; they are different molecules with different CAS numbers and different research histories.
They are sometimes discussed together as a combination, which is where the CagriSema component descriptor comes from, but the two vials are not interchangeable.
