Finnrick-tested with poor results. Tested across 3 peptide products with 38 total samples.
ZhuoYan lab is listed as active. Finnrick Grade D. Finnrick avg score: 6.1/10 across 38 samples (3 products). Below-average quality. Exercise caution.
ZhuoYan lab holds independent lab grade D, assigned across 38 graded samples, average score 6.1/10. 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 ZhuoYan lab, 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.
