Research peptides / Buying guide
Check the report against the lot.
A purchasing checklist for the documents that accompany research peptides.
Start with the lot number
Bluum’s COA lookup retrieves published laboratory reports by lot number. The library includes both current and archived batches. A report being available does not, by itself, establish which lot will be supplied with a new order.
- Find the lot number on the vial label or order information.
- Enter that exact number in Bluum’s lookup.
- Check that the product name and lot on the document match your records.
- If you are checking before purchasing, confirm the lot to be shipped with Bluum.
Read the test, not just the percentage
List the tests required by your laboratory protocol, then check which of them the report actually covers. A purity percentage is not a substitute for a separate identity, content or contamination result. Do not assume that a result shown for one batch applies to every batch or size.
Check the document details
- Sample: the compound name, lot identifier and stated amount, where provided.
- Laboratory: the named testing organization and report identifier.
- Date: when the reported work took place, and whether the record applies to the lot being supplied.
- Method and result: what was measured, its units and any stated limits or qualifications.
Keep uncertainty visible
If a required test is missing, treat it as unconfirmed. If a batch number differs or a document is unreadable, ask Bluum for the applicable record before relying on it. A research material’s analytical report does not establish suitability for human or veterinary use.
Save the report with your laboratory records
Keep a copy of the applicable document with the purchase record and lot identifier. This makes it easier to trace the material used in a later experiment.
