Peptide Testing Facilities in China
Laboratories and testing services with a confirmed facility in China, with the testing services, locations and ordering details each publishes on its own website.

How this page works: Facilities are evaluated on what their own websites publish, using the PAL Testing Evidence Score. Claimed profiles and PAL Pro subscriptions never change a finding, a score or a position. Peptide Ad Lab does not test samples and has not audited these facilities. Advertiser disclosure.

How facilities are evaluated
The PAL Testing Evidence Score (v1) awards up to 30 points for information a testing business publishes about itself, shown on a 0–10 scale:
- Facility transparency — 6 points
- Analytical scope — 9 points
- Quality & reporting — 10 points
- Ordering transparency — 5 points
Anything we could not find earns no points and is shown as “Not found in public sources” — it is not treated as a “no”. Only laboratories that perform the analyses themselves, are operating, accept outside samples, have a confirmed facility in the country and document at least two of purity, identity and quantity testing are ranked. Coordinators, manufacturers with analytical services, global networks and planned facilities are listed separately without a number.
Frequently Asked Questions
How are the testing facilities in China ranked?
By the PAL Testing Evidence Score: up to 30 points for facility transparency, analytical scope, quality and reporting, and ordering transparency, based only on what each business publishes on its own website. Ties are broken by the number of documented testing services, then by name.
Why is a company that accepts samples from China not listed here?
Country pages only include businesses whose own website places a facility in China. Accepting or collecting samples from a country is not the same as testing there.
What is the difference between a laboratory and a testing coordinator?
A laboratory runs the analyses itself. A testing coordinator takes orders and forwards samples to partner laboratories. Coordinators are listed separately and are not ranked against laboratories.
Does a paid PAL Pro profile rank higher?
No. PAL Pro adds profile features for verified owners. It does not change any finding, score, eligibility or position.
Why does a facility show no score?
It is listed without a number when it is not an independent laboratory, is not yet operating, its facility location is not confirmed, or it documents fewer than two of purity, identity and quantity testing. The reason is shown on its card.
