What labs ask us, and what we provide
| You need | What we provide |
|---|---|
| A certificate for the exact batch | The manufacturer's certificate of analysis with every batch, sent on request before you order |
| Purity | HPLC purity on the certificate, with the method; ask us for the chromatogram |
| Identity | Mass spectrometry result against the expected mass |
| Sequence and molecular weight | On every product page and certificate |
| Peptide content and salt form | Net peptide content and counter-ion where the manufacturer reports them (why they matter) |
| Storage and shipping conditions | On the label and the packing list; shipped at the labelled temperature |
| Safety data sheet | On request |
| Invoices your finance team can process | Documents in your institution's name, with your purchase order reference on them |
What we supply
Research-grade peptides from our catalogue, in boxes of 10 vials at the strengths listed on each product page, plus laboratory supplies such as bacteriostatic water. See the research-grade catalogue
We are a distributor, so we don't make peptides ourselves. If you need a sequence that isn't in our catalogue, tell us when you ask for a quote and we'll say plainly whether we can source it with full batch documents. If we can't, a custom synthesis company is the right supplier, and we'd rather tell you that than take an order we can't document.
How an order works
- Open a research account. We verify your institution and the responsible researcher once, then you can order whenever you need. What we check
- Ask for a quote. Product, strength, quantity and delivery address. We reply within one working day; quotes are valid for 14 days and state the lead time.
- Sign the end-use declaration with the order: laboratory research by qualified staff, no use in people or animals, no resale for those uses. Read the declaration
- Payment in full before dispatch, unless other terms are agreed in writing.
- Delivery at the labelled storage temperature, with the packing list, delivery note and certificate.
For your safety office and procurement team
- Safety data sheets. If your safety office needs the safety data sheet for a COSHH risk assessment before the order is placed, ask for it with your quote request.
- New-supplier forms. Send us your institution's form and we'll complete it: company details and bank details, on our letterhead.
- Quotations your system can read. One page per quote, with product, strength, quantity, price, lead time and delivery terms, so it can be attached to a requisition as it is.
Handling, once it arrives
Lyophilised peptides keep best cold, dry and dark. Our storage and handling guide covers temperatures, opening vials without condensation, solution storage and dissolving peptides for experiments, with sources. How our peptides are tested explains what each certificate does and doesn't prove.
What we won't do
We give no dosing or usage advice, we don't describe research products in terms of effects, and we don't supply anyone we can't verify. If a request looks like supply for use in people, we decline it. These rules protect the integrity of research supply, and they are the reason a research account takes a little longer to open than a shop checkout.

Questions labs ask
- Can you invoice our institution against a purchase order?
Yes. Documents are issued in your institution's name, with your purchase order reference on them. Payment is due before dispatch unless we agree other terms in writing.
- Do you provide the chromatogram and mass spectrum?
Ask us for them for any batch. If they aren't already on file, we request them from the manufacturer.
- Do you do custom peptide synthesis?
No. We are a distributor and don't make peptides ourselves. If you need a sequence that isn't listed, ask: we'll tell you plainly whether we can source it with full batch documents.
- How long does verification take?
We check your institution and responsible researcher once, when you open the account. After that, orders go straight to quotation.
