How We Evaluate Vendors

Every vendor is reviewed against the same core factors before a trust designation is assigned.

Business identityWe look for a real operating company, not only a registered-agent address or shell.
Lab and COA verificationWe identify the lab, confirm the reports are verifiable, and look for batch-specific documentation.
Testing coverageVerified requires third-party identity, purity, and quantitative content or potency testing. Identity or molecular-mass confirmation alone is not enough. We also record whether endotoxin, sterility, and heavy-metals testing is provided.
Results versus specificationWe compare the reported result with the certificate’s own stated acceptance criteria—not simply whether a result is present.
Community footprintWe consider the vendor’s public track record, customer history, and established marketplace reputation.

Verified

The vendor has passed our documentation-based review across the factors above, including the minimum testing standard. Submit accurate company information and a public testing or COA page to be considered.

Vetted

Peptide Protocols also has direct experience with the vendor’s ordering, fulfillment or processing, and product evaluation. Vetted status cannot be earned from application materials alone and is never guaranteed.

Directory inclusion is not an endorsement. Submitting this form does not guarantee acceptance or a Verified or Vetted designation.
