About Janoshik Analytical

Janoshik Analytical is an independent laboratory in the Czech Republic that has become the de-facto standard for verifying research peptides. It runs HPLC purity analysis (HPLC-UV around 214 nm), mass-spec / LC-MS identity confirmation, and content/quantity testing that measures the actual milligrams of peptide against the label claim. Add-on assays include endotoxin (LAL), sterility, residual solvents (GC), heavy metals and amino-acid analysis. What sets Janoshik apart is public verification: every certificate of analysis carries a batch ID and QR code that can be checked against the lab's database at verify.janoshik.com. Fabricated or doctored COAs fail this check — which is exactly why a Janoshik-verified result is treated as independent evidence rather than a vendor's marketing claim. Turnaround is advertised at roughly 96 hours on average with a guarantee of up to 21 days; community-reported times vary. Pricing is per-peptide and listed on the lab's own pricelist (community-reported figures are approximate — check the live pricelist for current rates).

How to read a Janoshik Analytical COA

A Certificate of Analysis is a lab’s signed result for a specific batch — purity, identity and content. Trust depends on whether it’s independently verifiable, not vendor-hosted.
