PSPeptides Lab Testing and COA: What to Verify
A “third-party tested” claim is only the beginning. The useful question is whether a report is batch-specific, current, traceable and relevant to the exact material being sold.
What PSPeptides claims
Its certifications page states that products are tested using HPLC and mass spectrometry, that COAs are provided, and that testing is performed by independent laboratories. The company also advertises a 99% minimum purity standard.
COA checklist
- Check product name and analyte identity.
- Look for a lot or batch identifier that can be matched to the item.
- Check sample/test dates.
- Identify the testing laboratory.
- Review the method used, not just the headline purity number.
- Look for full report pages rather than a cropped screenshot.
- Remember that purity testing does not automatically establish sterility, safety, or suitability for human use.
Why traceability matters
A certificate can only inform your evaluation if you can connect it to the batch you received. Public reviews are useful for spotting recurring customer concerns, but they cannot substitute for actual batch documentation.
Important distinction: vendor testing claims do not mean a product is FDA-approved. FDA says unapproved and compounded products are not reviewed in the same way as FDA-approved drugs for safety, effectiveness, and quality before marketing.
