10mgHow to Verify Our Results
Click Any Report
Each report card above links directly to the issuing lab's verification portal — a third-party website we don't control.
Verify the QR Code
Janoshik reports include a scannable QR code. Scan it to confirm the report hasn't been tampered with.
Check the Data
Review HPLC purity percentages, sample weight, and testing methodology — all verified by an independent lab.
Why Janoshik?
Janoshik Analytical is the most widely recognized independent peptide testing laboratory in the research community. With over a decade of operation and 100,000+ monthly visitors to their public verification portal, they've become the de facto standard for independent peptide quality verification.
Their reports include QR-code verification to prevent tampering — any modification to a report invalidates the QR code. This means when you see a purity number on our site, you can independently confirm it hasn't been altered.
We chose Janoshik because we wanted our customers to be able to verify our claims without taking our word for it. Most peptide vendors provide in-house testing certificates that can't be independently verified. We believe transparency builds trust — not claims.
Two Layers of Testing
Layer 1: Supplier Batch Specification
Every product ships to the supplier's published batch specification (identity and purity, class-level). This applies to the full catalogue. CertaPeptides is a reseller and does not test in-house.
Layer 2: Independent Third-Party Verification
Selected products are sent to an independent third-party lab for verification. These reports are publicly available and independently verifiable — we have no control over the results or the verification portal.
