How to check a peptide catalog identity
A familiar abbreviation is a lead, not a chemical verification.
Ask for the full specification.
Retain the exact supplier product name, size and any subtype. If a sequence, salt, counterion, modification or formulation matters to a research question, require the actual specification rather than guessing from a short name.
Keep unresolved labels unresolved.
ClearCost does not turn GLP-1, GLP-2 or GLP-3 catalog labels into named molecules without source confirmation. A blend name also does not establish its ingredient ratios. Similar names are not enough to merge products or research claims.
Connect the documents.
The catalog specification, lot report and shipped label should identify the same material. A paper about a named molecule does not establish that a retail listing contains that molecule.
