Why Recent COAs Matter
Last updated: July 2026 · Research-use information only
Overview
Why the date on a COA is one of the most important fields. This guide is part of the Push for Peptides research hub and is provided for research-use and informational purposes only. It does not include dosage, human-use instructions, or medical claims.
Why this matters for COA review
When reviewing publicly available testing records, focus on whether the record clearly identifies the product, the supplier, a batch or lot number, a testing date, and a testing method. Records that omit these fields are harder to interpret.
How to apply it
- Match the product name on the record to the listing.
- Confirm a batch or lot number is present.
- Check how recent the testing date is.
- Note the testing method, such as HPLC or LC-MS.
- Look for any publicly reported purity or amount.
Neutral, not an endorsement
