Finnrick-tested with very poor results. Tested across 2 peptide products with 21 total samples.
ZePeptide is listed as inactive — its storefront did not respond when the liveness check last ran. Finnrick Grade E. Finnrick avg score: 6.5/10 across 21 samples (2 products). Poor quality detected in testing. Use with extreme caution. domain no longer exists (no NS or SOA) (checked 2026-08-10).
ZePeptide holds independent lab grade E, assigned across 21 graded samples, average score 6.5/10. 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 ZePeptide, 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.
