Verify your 502BIO product
Every 502BIO vial ships with a unique authentication code on the box. Enter it below to confirm your product is genuine and to view its certificate of analysis. Each code should verify once — if a code has been checked before, it may signal a counterfeit.
1 · Find the code
Scratch off the panel (or scan the QR) on your 502BIO box to reveal the 12-character code.
2 · Verify it
Enter it above. We check it against our database — a genuine code verifies on its first check.
3 · Get the COA
A verified code unlocks the certificate of analysis (HPLC + mass spec) for that exact lot.
Why verification matters. Counterfeit research peptides are common. 502BIO assigns every single vial its own one-time code tied to its production lot, so you can confirm authenticity and trace the exact batch — something most suppliers can’t offer.
