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: In-House Testing
Every batch is tested using HPLC and mass spectrometry before it ships. This covers purity analysis, identity confirmation, and endotoxin screening. All 129+ products go through this process.
Layer 2: Janoshik Verification
Selected products are sent to Janoshik for independent third-party verification. These reports are publicly available and independently verifiable — we have no control over the results or the verification portal.
