Why the certificate matters

“A purity figure without a batch number attached to it is a marketing claim, not a result.”

Every lot is assayed independently and the chromatogram is published against the lot number stamped on your vial. Send us that number and you get the report for the vial in your hand.

How testing works

Before you order

The things people ask first

Delivery

  • Order before 12pm on a working day and it ships the same day, tracked.
  • UK mainland is normally next working day; the Highlands, Islands, NI and the Channel Islands can take one more.
  • Tracked 24 or Tracked 48, your choice at checkout, at a flat rate either way — and Tracked 24 free above the threshold shown there.
  • Unbranded packaging, gel pack and insulating liner, vials in a moulded insert.
Delivery in full

Returns & refunds

  • Consumers get 14 days to cancel for any reason under the Consumer Contracts Regulations 2013.
  • Faulty, wrong or missing? A 30-day right to reject for a full refund, and we cover the return.
  • Unopened vials with an intact seal come back within 30 days as a goodwill policy.
  • An opened or reconstituted vial cannot come back. There is no way for us to verify how it was stored.
Returns in full

Certificates of analysis

  • Every lot is assayed twice: once by the manufacturing facility, once by an independent lab we contract separately.
  • It is the independent lab's figure that goes on the certificate.
  • Each vial carries its lot number on the label, and the certificate is filed against that exact lot.
  • Send us the lot number and we return the PDF and the raw chromatogram the same working day.
How we test

Contact

  • Email is the fastest route and reaches everyone. We answer within one working day.
  • Include the order reference or lot number and we can usually resolve it in one reply.
  • We can help with certificates, safety data sheets, order status, bulk pricing and purity disputes.
  • Everything here is sold for laboratory research, so we cannot advise on dosing, administration or protocols.
