Six commitments
1. A certificate for every batch. We ship a batch only with the manufacturer's certificate of analysis, and you can read it before you order. Certificate library
2. Traceable to the line. Batch number and expiry are recorded on every packing list and delivery note, so any vial can be traced back to its certificate.
3. The right temperature. Each product travels at its labelled storage temperature, with temperature indicators where needed. Storage and shipping
4. Licensed buyers only, where a licence is required. Licensed medicines go only to buyers who hold the licence their market requires. Licensed medicines
5. Only where permitted. We supply a product only where it is registered or permitted in the destination market, and research-grade products only to research buyers we have verified. Research buyer verification
6. Honest descriptions. We describe products only for their permitted use, and we never make health claims for research-grade products.
UK Master Peptides is a distributor. The certificates we supply come from each product's manufacturer, and we say clearly when a report is independent. How our peptides are tested
Where our peptides come from
We source from manufacturers that pass our supplier checks, and we keep each manufacturer's batch documentation for every lot we sell.

For licensed medicines, we also need your pharmacy, wholesale or hospital licence and any import permit; for cosmetic ingredients, your company registration and the product's intended cosmetic use; for research-grade products, your institution's details and a signed end-use declaration. How to order has the full process.
Questions people ask
- How do you check your suppliers?
We buy from manufacturers that have passed our supplier checks, and every batch must come with its manufacturer's certificate of analysis before we will sell it.
- Can I trace a vial back to its certificate?
Yes. The batch number on the label is on your packing list and delivery note, and on the certificate for that batch.
