The cheapest quote is rarely the cheapest order

A €38 vial from an anonymous seller looks like a bargain next to a €55 vial from a lab with a published COA and cold-chain — until the first shipment arrives lukewarm, the second one gets seized, and the third comes back with 82% purity on your own re-test. By the third re-order the "cheap" supplier has cost you more per usable vial than the premium one, plus a fortnight of protocol delays.

What to ask any peptide supplier — before you pay

Show me the batch-matched COA for the specific lot my order will ship from.
Name the third-party lab that ran the HPLC and mass-spec.
What ice-pack profile do you use to my postcode at this time of year?
What happens if my independent re-test comes back below your stated purity?
Where is your dispatch address, and who signs off release?

Frequently asked questions

Why is Regena more expensive than the cheapest sellers I see online?+

The cheapest sellers skip third-party HPLC testing, publish stock COAs (not batch-matched), and ship without cold-chain. Once you add the cost of a failed batch, a lost shipment or a re-order, they aren't actually cheaper — they're just quoted cheaper.

How do I know a supplier's COA is real?+

A real COA names the third-party lab, lists a batch code that matches your vial, and includes the HPLC chromatogram and mass-spec spectrum. Stock COAs recycle a single PDF for every batch of the same peptide — an immediate red flag.

What about suppliers that ship from within my country?+

Domestic dispatch is convenient but says nothing about purity or testing. Ask for the batch-matched COA before ordering — if it doesn't exist, the shipping speed is irrelevant.
