How to buy research peptides in the UK
A practical guide to choosing a UK supplier, checking certificates, and what to expect from payment and delivery.
Before comparing suppliers, write down the compound, the vial size and the quantity your research needs. For peptides that are sold under more than one name, note the exact sequence or form you require; for blends, note the amount of each component. This makes it much easier to check that a product, and its certificate, actually match.
Products are for laboratory research use only. Keep a short requirement sheet with the full molecular name, sequence or modifications where needed, supplied form, amount basis and the documents required for the lot.

A certificate of analysis (COA) is the main evidence of what is in a vial. Look at it before you buy, not after the parcel arrives.
The material name and label claim should match the product and vial size you are buying, not a different strength or a similar compound.
Results apply to one batch. The lot number lets you match the report to the vial you receive.
Identity is usually confirmed by mass spectrometry, purity by HPLC, and measured content tells you how much material is in the vial. A purity percentage on its own does not tell you the amount.
You should be able to see who tested the sample and when. An analysis date is not an expiry date.
No certificate, one generic certificate reused across products or sizes, or a report that has been cropped so the batch or laboratory details are missing.

A named company, a company number you can check on Companies House, and a working contact email.
Written terms of sale that explain delivery, cancellations, returns and what happens if something is wrong.
Stock dispatched from the UK with tracking, and a clear dispatch cut-off time.
Delivery charges and any discounts shown before checkout, and a clear statement on whether VAT is included.
Look for the product, lot, property, issuing laboratory and document reference behind each quality statement. Keep information described as untested, unknown or undisclosed distinct.
Ask three concrete questions: which complete molecular description applies, what does the stated amount measure, and which documents cover the lot offered? If a required field is missing, ask for that field and retain the reply with the quotation.
Compare the compound form, labelled or measured amount, number of vials, included testing and total delivered price. Keep excluded tests, additional charges, quotation date and validity visible. Leave unknown costs unresolved instead of counting them as zero.
Turn broad quality wording into a document question: for “high purity”, ask for the lot, method and reporting basis; for “fully tested”, ask which tests and results are supplied. A clear limitation is more useful than an unsupported assurance.

Compare the material description, stated vial size, quantity and delivery charge together. A price for a vial is different from a price for the whole order.
At the current listed prices: One BPC-157 5 mg vial is £20.99 delivered in the UK (including £4.99 delivery). One BPC-157 10 mg vial is £30.99 delivered in the UK (including £4.99 delivery). One Semax 10 mg vial is £29.99 delivered in the UK (including £4.99 delivery). One AOD9604 5 mg vial is £28.99 delivered in the UK (including £4.99 delivery). Each example is for one vial in an otherwise empty basket, before any payment-method discount. Check your basket for the total for your order.
Before paying, check which payment method you are using and follow the instructions for that method. For a bank transfer, use the amount and reference supplied for your order. If an ordering detail is unclear, ask before sending payment.
Before comparing reports, check who issued the document, which sample and lot it covers, and which properties were tested. Use the document checklist to record unanswered questions.

Make sure the seal is intact and nothing is damaged. Do not use a product if the seal is broken.
Check the compound, strength and batch number against your order and the certificate.
Follow the storage conditions on the label, such as 2–8 °C, and keep the original labelled packaging.
Note the date received, inspection date if different, labelled amount, lot and report reference. Record observed packaging condition without inferring analytical quality from appearance.
For example, if two vials show lot A and a third shows lot B, a report naming only A leaves B unresolved. Keep the labels as received, ask for the B report and date any later document addition. This is an illustrative record check.
