We don’t know Peptide Sciences’ internal processes. Neither does anyone writing about them from outside. What we do know is exactly what verifiable third-party testing evidence looks like. Here’s the framework to apply it to any vendor.
No regulatory body checks peptide vendor quality. The only protection is knowing which signals separate a legit source from a scam. A 7-point checklist that works on any vendor, including NorthPeptide itself.
Third-party tested means nothing without knowing which lab and what the test showed. A researcher guide to the recognized independent peptide testing labs (Janoshik, ACS Lab, MZ Biolabs, Finnrick) and how to verify any COA in under 60 seconds.
