    Press Order on WhatsApp or Email. Your order is written into the message for you.

  3. 3

    Confirm & pay

    We confirm stock and your total including postage, then send payment details.

Quality

Documentation, not assurances

Research is only reproducible if the material is characterised. Everything we ship is accompanied by the paperwork to prove what it is.

Certificate of analysis

Every batch is supplied with documentation stating purity, identity and the analytical method used. Batch numbers are traceable.

Independent testing

Purity is verified by third-party HPLC and mass spectrometry rather than self-certified.

Cold chain handling

Stock is held and dispatched under controlled temperature, with insulated packaging as standard.

Traceable records

Batch and consignment records are retained so results can be tied back to material years later.

FAQ

Questions

Who can order?

We supply research professionals, businesses and institutions. You must be 18 or over and confirm that everything you order is for laboratory research. We don't sell to members of the public.

How do I place an order?

Message us on WhatsApp or by email with the peptides or systems you want and the quantities. Every Order button on this site starts that message for you. We'll reply to confirm stock, your total including postage, and how to pay.

How much is postage?

Postage and packaging is added to every order, and we confirm the exact amount with your order total before you pay.

What is a research system?

A pre-selected set of vials sold together for less than buying each one separately. Each system lists exactly which vials are included and how much you save.

Do you provide a certificate of analysis?

Yes. Every batch comes with a certificate of analysis showing purity and identity, and the batch number on the certificate matches the vial.

How should vials be stored?

Storage conditions are listed on each peptide's page. Lyophilised peptides should be kept cold and away from light until they are used.

Can you advise on how to use a compound?

No. Everything we sell is for laboratory research only, and we don't give advice on the use, dosing or administration of any compound. None of our products are licensed for human or veterinary use.

What if there's a problem with my order?

Contact us as soon as your parcel arrives and we'll put it right.
