Independent testing
you can verify.
Certa Diagnostics was founded to ensure product quality and consumer safety. We're an independent testing service offering reliable, verifiable analysis of peptides and research compounds — every result is reviewed by a qualified chemist before the certificate is issued.
Confidentiality
100% anonymous, private reports. Samples are tracked by ID only.
Precision & accuracy
Validated HPLC and mass-spectrometry methods, reviewed by qualified PhD chemists.
Integrity & transparency
Unbiased testing with results anyone can verify by QR code or certificate number.
Fast turnaround
Predictable timelines, with rush options when you need results sooner.
Meet the chemists.
Every result is reviewed and personally signed by one of them before a certificate is issued.

Dr. Hull earned his Ph.D. in Chemistry at the University of Minnesota and spent 33 years as a process development chemist at Dow Chemical, turning lab chemistry into commercial-scale production. He is a named inventor on 24 U.S. patents and has published in the Journal of Organic Chemistry and Macromolecules. As a Research Assistant Professor at Michigan State University he led contract R&D for industry clients and served as the labs' Safety Officer. His instrument work spans HPLC, GC/MS, NMR and FTIR — four decades of industrial rigor behind every result he signs.

Dr. Zhang earned his Ph.D. at the University of Rhode Island, where his research on nanoparticle characterization by ICP-MS was published in leading journals, after a B.S. in Chemistry from Shandong Polytechnic University. Over 12 years he has worked inside some of the biggest names in science: lead analytical chemist at EAG (now Eurofins), Thermo Fisher Scientific, Benjamin Moore, and seven years as a Senior Scientist in Johnson & Johnson's medical device division. His specialty is unknown-compound identification — taking a sample apart with LC-QTOF, GC-MS and high-resolution mass spectrometry and naming exactly what is in it. A member of the American Chemical Society and fluent in English and Mandarin, he brings big-pharma rigor to every result he signs.
