Description
The cagrilintide 5mg vial is supplied as a long acting amylin analog peptide, freeze dried and sealed. The fill weight is 5 mg of net peptide content. The cake is white to off-white. Every figure quoted on this page comes from the certificate issued against the lot number on the vial. For laboratory research use, and not for human or veterinary consumption.
It is investigational, with no marketing authorization in any country. The label on the cagrilintide 5mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

Freeze dried powder, fill weight and price per milligram
Lyophilized means the material was frozen and then dried under reduced pressure, so the ice sublimed straight to vapour. Heat drying would damage the sequence, and a liquid product would arrive degraded. The finished cake is porous and light. It can look like a wafer, a crust, or almost nothing at all in a small fill, and that variation is normal rather than a defect. Nothing about the cagrilintide 5mg vial is sold by volume.
How the per milligram figure is worked out
Milligram content is the unit the cagrilintide 5mg vial is sold in, because it is the only figure that makes two listings comparable. At the listed price this comes to something like $37.80 per milligram. It is printed under the price rather than buried, because the alternative is a page where a large vial and a small one cannot be compared at all. Compare the cagrilintide 5mg vial on that basis rather than on the price of the glass. The case is made at greater length in why price per milligram beats the price on the bottle.
The documentation that comes with the cagrilintide 5mg vial
What a certificate of analysis should contain is not mysterious. The compound as named. The lot. When it was tested. The purity figure and the chromatogram it came from. The observed mass against the calculated mass. The water content. Who did the testing. Where any of those are absent, the document is describing less than it appears to describe. The certificate issued with the cagrilintide 5mg vial is specific to the lot and not to the product line.
The assay is performed by a contract laboratory unconnected to this business. Any lot that comes back below its stated milligram content is pulled from sale, and the certificate stays published on the results page with everything else instead of quietly disappearing. Stock is withdrawn from sale where the certificate for the cagrilintide 5mg vial does not support the figures here. See how to read a certificate of analysis and check the lab before you check the numbers.
Purity, identity and moisture are three different measurements
Purity is an HPLC number, reported as percent of total peak area. The sample travels through a column that pulls the components apart, and a detector draws the result as a trace. The chromatogram is on the certificate rather than the headline figure alone, so the shape and position of the minor peaks can be read instead of taken on trust. The same methods are run on the cagrilintide 5mg vial as on every other lot on this shelf, and formulae and expected masses for compounds of this class can be checked through the NCBI chemistry and literature databases.
Why the name is inconsistent, and how to store the cagrilintide 5mg vial
Nomenclature in this field is a mess. Laboratory codes, INCI names assigned for cosmetic labelling, nonproprietary names and supplier catalogue names all circulate at once, and one molecule can appear in four catalogues under four names. Some names in this category spell out an intended effect once expanded. Those stay abbreviated, because writing them out would turn a catalogue entry into an assertion about biological activity. The catalogue name carried by this vial is the one the trade uses, and a trade name is not an identifier.
Sealed, cold, dark and dry. Short term storage at refrigerator temperature and long term storage at minus 20 degrees Celsius or colder are the standard conditions for lyophilized peptide material of this kind. Keep the certificate with the vial, since the lot number is the only thing joining the two.
Research use only, stated plainly
This is a laboratory reference material. It is not for human or veterinary consumption, it is not a food and it is not a drug. There is no dose on this page, no timing, no route, no site and no reconstitution method, and asking for any of them will not produce them. Bacteriostatic water, diluents and syringes are stocked separately and are not sold as a set with this item. No part of this page describes a use for this material in a person or an animal.
A research use only statement is not a legal strategy and is not treated as one here. Warning letters in this area turned on what the rest of the page said, not on whether a disclaimer was present. See research use only is not a legal strategy, and the FDA warning letter archive.
Withdrawn lots stay published alongside the rest rather than quietly disappearing. The page is a specification, and the specification is all of it. This item sits on the metabolic peptide shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
