Finnrick-tested with very poor results. Tested across 4 peptide products with 59 total samples.
Xian Yihang Technology is listed as active. Finnrick Grade E. Finnrick avg score: 6.5/10 across 59 samples (4 products). Poor quality detected in testing. Use with extreme caution.
Xian Yihang Technology holds independent lab grade E, assigned across 59 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 Xian Yihang Technology, 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.
