Haikou Mingheng Biotechnology holds independent lab grade E, assigned across 24 graded samples, average score 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 Haikou Mingheng Biotechnology, 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.
