–Not scored

Listed without a score

Testing coordinator: samples are analysed by partner laboratories. The criteria below are still shown for transparency.

Overview

The site states that QCTests is a China-based coordination service for peptide and cosmetic testing, working with selected third-party laboratories in China and overseas rather than performing analyses itself. It describes reviewing laboratory-reported results and issuing a traceable Certificate of Analysis, with private verification codes and no public certificate directory. Listed core services include peptide identity by mass spectrometry, HPLC purity analysis, net peptide content, endotoxin testing, and heavy metal residues, with reference pricing given in CNY for China-based testing and USD for an overseas partner laboratory (BiovanLab). The site names ten partner laboratories across Chinese cities and states their accreditation labels apply to those entities. Contact is via a published support email. Details are summarised from the company's own website and have not been independently audited.

Is this your facility?

Claiming is free. PAL first verifies that you are authorized to act for the business. Verified owners can then use three separate routes. Peptide Ad Lab never charges a business to correct a factual inaccuracy.

Company-provided updatesYour description, testing services, methods and instruments, facility locations, sample submission link, turnaround, pricing and contact details, shown in a section labelled “Provided by the company”. Not checked by PAL and not used in the score. Free: sent to PAL as correction requests. PAL Pro: published directly.
PAL-reviewed evidenceDocuments or links for a scoring criterion. PAL reviews them under the same rule used for every facility; only accepted evidence changes a finding. Any plan.
PAL-verified lab credentialsAccreditations such as ISO/IEC 17025. They count only after PAL finds them in the accreditor’s public directory. Any plan.

PAL Pro is an optional paid plan for company-provided updates, extra images and the PAL Pro badge. It never verifies a credential, accepts evidence, or changes a finding, score, eligibility or ranking position.

Ownership verification confirms that you control the business. It is separate from laboratory credentials and from PAL Pro, it is not an endorsement, and it does not change any finding or score.
