How we test

From laboratory to label

  1. Independent analysisEach batch goes to an independent laboratory (Janoshik or Marfleet) for HPLC purity and identity testing. We don't test in-house.
  2. Batch-matched documentationThe batch number printed on each vial matches the documentation packed with your order.
  3. Shipped togetherDocumentation for every item travels in the same parcel, so it stays with the batch it describes.

Research peptides UK: frequently asked questions

What are research peptides?

Research peptides are synthetic peptides (short chains of amino acids joined by peptide bonds) supplied for in-vitro and preclinical laboratory research. They are not licensed medicines, and suppliers label them for research use only.

What does "research use only" (RUO) mean?

Research use only means a product is intended solely for laboratory research. It is not for diagnostic or therapeutic use and must not be administered to people or animals. Every Peptaro product is supplied on that basis, and checkout requires three research-use confirmations.

Is there a minimum order?

Yes. We supply research quantities from £299.00 per order. Every order ships free, tracked and cold-packed with its batch documentation. Research kits meet the minimum on their own.

When will my order be dispatched?

Orders placed and paid before 3pm, Monday to Friday, are dispatched the same day. Orders placed after 3pm, at the weekend or on a bank holiday go out on the next working day. Bank transfer orders are dispatched as soon as the payment reaches us.

How much does delivery cost?

Delivery is free on every order: Royal Mail Tracked 24, dispatched the same working day for orders placed before 3pm UK time.

How long does delivery take?

Most orders arrive the next working day after dispatch. Every order goes by Royal Mail Tracked 24, which aims for next-day delivery. That is Royal Mail's target rather than a guarantee, so allow a little longer at busy times.

How do I track my order?

Your tracking number is in the dispatch email we send when your parcel is handed to Royal Mail. If you ordered with an account, you can also see the order status in your account .

How is my order packed?

Orders ship sealed and securely packed for transit. Every vial is labelled with the compound, amount and batch number.

Do you ship outside the UK?

No. We deliver to UK addresses only.

Who tests your peptides?

Independent laboratories, never us. Batches tested from September 2026 have been tested by Janoshik Analytical. Certificates published for earlier batches were issued by Marfleet Analytical Services, and those reports remain published for the batches they cover. Where a batch has no independent report, the certificate is labelled supplier-reported and independent verification is pending. No figure on this site is produced by us.
