Finnrick-tested with poor results. Tested across 2 peptide products with 27 total samples.
Bfflink is listed as active. Finnrick Grade D. Finnrick avg score: 7.9/10 across 27 samples (2 products). Below-average quality. Exercise caution.
Bfflink holds independent lab grade D, assigned across 27 graded samples, average score 7.9/10. 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 Bfflink, and we have not yet compiled a profile of its own website. An untested vendor has not failed a test — this is an absence of evidence, not evidence against it.
