Authentication System

Every vial.
Verified once.

The peptide supply chain has a counterfeiting problem. Meriagan Labs addresses this with a single-use cryptographic token affixed to every vial at dispatch. The token can only be authenticated once — any subsequent scan reveals the original verification timestamp.

I
Receive your order
Tamper-evident QR label sealed over the vial cap. Unique 12-character cryptographic token — mathematically irreproducible.
II
Scan with any camera
No application required. Opens meriaganlabs.co.uk/verify/[token] directly. Works on any iOS or Android device.
III
Certificate of Analysis displayed
Full COA renders: compound identity, batch number, purity result, manufacture date, expiry and vial photograph.
IV
Token locked — chain secured
Token is flagged as verified with timestamp. Any second scan displays a fraud alert with the original verification time.

How Meriagan
operates.

01
Independent testing
Every batch is analysed by HPLC and mass spectrometry before dispatch. Results are documented in a printed Certificate of Analysis shipped with each order.
02
Single-use authentication
Each vial carries a unique cryptographic token. First scan authenticates. Second scan raises a fraud alert. Immutable chain of custody from our facility to your bench.
03
Discreet worldwide dispatch
Orders dispatched from our UK fulfilment partner in neutral packaging. Tracking provided. All compounds labelled for research use in compliance with applicable regulations.
04
Direct enquiry model
We do not operate a public checkout. Pricing and availability confirmed directly via enquiry. This allows us to confirm research intent and ensure appropriate documentation.
