Precision Peptide Co holds independent lab grade B, assigned across 21 graded samples, average score 7.3/10. That grade comes from an independent grader's own sampling, not from PeptideAtlas, and it describes the samples that grader obtained rather than every batch sold.
No independent third-party assay is on file for Precision Peptide Co, and its storefront did not respond when we last tried to read it. An untested vendor has not failed a test — this is an absence of evidence, not evidence against it.
