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 worksBefore you order
The things people ask first
Delivery
- Order before 2pm 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.
- Flat-rate tracked delivery, free above the threshold shown at checkout.
- Unbranded packaging, gel pack and insulating liner, vials in a moulded insert.
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.
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.
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.
The full wording for all of the above is on the policies page, along with terms of sale, privacy and the research-use conditions you accept when you order.
