Finnrick-tested with mixed results. Tested across 9 peptide products with 61 total samples.
Planet Peptide is listed as active. Finnrick Grade C. Finnrick avg score: 7.2/10 across 61 samples (9 products). Mixed quality — some products test well, others below average.
Planet Peptide holds independent lab grade C, assigned across 61 graded samples, average score 7.2/10. 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 Planet Peptide, 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.
