OUR MISSION
Precision in every vial.
Chinapeptides was started with a simple frustration: too many research compounds ship on a supplier’s word, with no paperwork to back it up. We set out to be the supplier we couldn’t find — one that treats every vial like it will end up in someone’s most important experiment.
We supply analytical-grade research peptides to laboratories and research organizations worldwide, synthesized to exacting standards and independently third-party tested before anything ships.
“Every batch is third-party tested before it ships — because your research deserves a known baseline, not a supplier’s word.”
INTEGRITY, VERIFIED
Don’t take our word for it.
Every lot is verified by independent laboratory analysis. Two methods do the heavy lifting:
Mass Spectrometry (MS)
Confirms the molecular weight matches the exact peptide sequence on the label — proving the vial contains what it claims, not a cheaper substitute.
HPLC Purity Analysis
Verifies ≥99% purity and quantifies every impurity present. A clean result isn’t assumed — it’s measured, printed on the COA, and matched to your lot.

OUR COMMITMENT TO SCIENCE
Research runs on trust.
Reproducible research starts with reproducible materials. We commit to consistent quality — lot after lot — so the results you get in January match the results you get in June. When batches never drift, your data never has to be questioned.
Research use only.
All products are supplied strictly for laboratory and in-vitro research use only. They are not drugs, foods, supplements, or cosmetics, and are not intended for human or veterinary use.
ANSWERS
Questions, answered.
Are your products third-party tested?
Yes. Every lot is tested for identity and purity before it ships, and a lot-matched Certificate of Analysis (COA) is available for each product. Purity is verified by HPLC and mass spectrometry to ≥99%.
Where do you ship?
Worldwide, with tracking on every order. Orders placed before 2PM typically ship the same business day.
What does ‘Research Use Only’ mean?
All products are supplied strictly for laboratory and in-vitro research use only. They are not drugs, foods, supplements, or cosmetics, and are not intended for human or veterinary use.
How do I get the COA for my lot?
Every product has a lot number printed on the vial. Email it to us along with the product name and we’ll send the matching Certificate of Analysis — or browse the COA Library to request one.
How should these compounds be stored?
Store lyophilized material at -20°C, protected from light and moisture. Consult the product COA for compound-specific handling.
