Reference pricing
Choose the right testing route.
Select by where the product is made, where the report will be used, and whether the sample can be shipped overseas.
China-accredited laboratory
Per sampleTesting in China · CNY
For Chinese manufacturers and exporters, or overseas clients testing products made by suppliers in China. Samples are tested in China.
MS identity + HPLC purity
Combined peptide authenticity and purity screening
Net peptide content
Active peptide content excluding water, salts and bulking agents
Endotoxin testing
Bacterial endotoxin concentration reported in EU/mg
Heavy metal residues
Residual heavy metal screening for the submitted sample
Best suited to China-based production and supplier quality control. Compound peptides and large proteins require project-specific confirmation.
BiovanLab · Overseas partner laboratory
Per sampleOverseas testing · USD
For China-based brands entering overseas markets and international clients who require testing outside China. Samples must be shipped overseas.
Mass spectrometry (MS)
Molecular weight and qualitative identity verification
HPLC analysis
Peptide purity and synthesis impurity assessment
LC–MS analysis
Joint separation and molecular weight analysis
Net peptide content
Absolute active peptide mass analysis
Endotoxin testing
Bacterial endotoxin concentration assessment
International shipping, customs and sample handling are confirmed separately. Typical sample guidance: ≥10 mg lyophilized powder or ≥2 mL liquid.
Reference prices reviewed September 2026. Final cost depends on the sample, method, quantity, turnaround, report requirements and shipping. The report issuer and applicable accreditation scope are confirmed before testing.
How it works
A simple offline testing process.
The website provides service information and registered COA verification. Quotations, shipping and testing coordination remain personal and offline; registration is only required for online verification and portal access.

Tell us about the sample
Share the product type, testing objective and available quantity.
- 02
Confirm scope offline
We confirm methods, sample requirements, selected laboratory, timing and final price.
- 03
Laboratory analysis
Your sample is tested by the selected third-party laboratory. QCTests reviews the reported results for COA preparation.
- 04
Receive and verify the COA
QCTests delivers the private PDF directly or through the client portal. Every COA includes a code and QR link; a registered account is required to view the online verification result.
Traceable by design
What a QCTests verification confirms.
Verification confirms that selected, non-confidential data matches the certificate record issued by QCTests. The original laboratory report and full PDF remain private.
Private verification code
Certificate number and code must match the issued record.
No public directory
Customer identities and original certificate files are not browsable.
Current status
Issued, superseded and revoked records can be distinguished online.
Knowledge base
