Finnrick-tested with insufficient data for grading. Tested across 1 peptide products with 1 total samples.
TCI is listed as active. Finnrick Grade X. Finnrick avg score: 7.6/10 across 1 samples (1 products). Insufficient data for a reliable grade.
TCI holds independent lab grade X, assigned across 1 graded sample, average score 7.6/10. 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 TCI, 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.
