Finnrick-tested with poor results. Tested across 2 peptide products with 25 total samples.
Top Peptide is listed as active. Finnrick Grade D. Finnrick avg score: 6.7/10 across 25 samples (2 products). Below-average quality. Exercise caution.
Top Peptide holds independent lab grade D, assigned across 25 graded samples, average score 6.7/10. 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 Top 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.
