Terms and Conditions

    Last updated: 8 October 2026

    PX Reagents Ltd, a company registered in Scotland under number SC890970, registered office 2/3, 48 Clyde Offices, West George Street, Glasgow, G2 1BP. Contact: Support@peptx.co.uk or our contact page.

    The short version: our products are sealed research reagents, so all sales are final. We do not accept cancellations once an order is paid, or returns. Damaged, missing or incorrect items must be reported within 24 hours of delivery with photos, and accepted claims are put right by replacement. Sections 7 to 9 explain this in full, including the rights the law gives consumers.

    1. About these terms

    These terms apply to every order placed with PX Reagents Ltd (“Peptx”, “we”, “us”) on peptx.co.uk or through our WhatsApp or Telegram ordering. By placing an order you accept them. The version on this page when you order is the one that applies to that order.

    2. Who can buy

    • You must be 18 or over.
    • Our products are sold for laboratory research only (section 3). We sell to researchers, laboratories and businesses.
    • If you buy as a consumer (an individual buying mainly outside a trade, business or profession), section 9 sets out the rights the law gives you. Everything else in these terms applies as far as the law allows.
    • We may refuse any order, and may ask for proof of identity, address or research use before we dispatch. We may cancel an order we have not dispatched where we reasonably suspect fraud, misuse, a false address or a breach of these terms. If it was paid, we refund it in full.

    3. Research use only

    All products are supplied strictly for in vitro laboratory research. They are not licensed medicines and must not be used for human or animal consumption or administration, clinical use, food, cosmetics, or any diagnostic or therapeutic purpose. We make no medical claims.

    By ordering you confirm that you will use the products only for lawful laboratory research, that you will store and handle them safely, and that you will comply with every law that applies to buying, importing, holding and using research reagents where you are. If you tell us, or we have good reason to believe, that products are meant for human or animal use, we will refuse or cancel the order.

    4. How we supply: UK Express, Factory Direct and Wholesale

    UK Express. We are the seller. Goods come from our own UK stock. We aim to dispatch within 24 hours of payment by Royal Mail Tracked 24. UK delivery typically takes 2 to 5 days from dispatch and can be affected by public holidays and Royal Mail service levels.

    Factory Direct. For Factory Direct orders we act as the intermediary between you and our manufacturing partner. We take your order and payment and place the order with the manufacturer, who makes, packs and ships it directly to you from outside the UK, normally within 48 hours. We do not hold, pack or inspect Factory Direct goods before they reach you. Delivery typically takes 9 to 15 days door to door; any service notice on the site gives the current timing.

    Wholesale. Wholesale orders are Factory Direct kits supplied through our wholesale manufacturing partner, and we act as the intermediary in the same way. Wholesale prices are shown only to signed-in members and apply to orders of at least 10 kits in any mix. Wholesale orders are paid by bank transfer, delivery is free, and UK delivery typically takes 7 to 11 days door to door.

    For Factory Direct and Wholesale orders, and every international delivery, you are the importer. You are responsible for making sure the goods can lawfully be imported and held where you are, and for any customs duties, import taxes and fees. Our responsibility for a Factory Direct or Wholesale order is what these terms set out (including section 8 for customs seizures).

    5. Orders and prices

    • Prices are in pounds sterling (GBP). The total at checkout is what you pay: the goods plus the delivery charge shown. There is no card fee.
    • Your order is accepted, and a contract formed, when your payment is confirmed and we send the order confirmation email. Until then we may decline it.
    • An unpaid order is released automatically when the payment window shown at checkout ends: 15 minutes for instant bank and card payments, 24 hours for an ordinary bank transfer.
    • If an obvious pricing or listing error gets through, we will contact you before dispatch. You can pay the correct price or cancel for a full refund.
    • Discount codes, referral credit and PX Points have no cash value, apply as stated at checkout, and can be withdrawn. One account per person. Orders that misuse them (for example through several accounts) may be cancelled and refunded.

    6. Payment

    • Pay by bank (UK). Open banking payments are made through Wallid, powered by Yapily Connect Ltd (authorised and regulated by the Financial Conduct Authority, firm reference 827001), or through Fena (Fena Labs Ltd, authorised by the Financial Conduct Authority, firm reference 934835). You approve each payment in your own banking app. The payee is PX Reagents Ltd, and we never see your bank login details.
    • International. International orders are paid through a secure Tide payment page or by bank transfer.
    • Chargebacks and disputes. If something is wrong, contact us first. If you raise a chargeback or payment dispute on an order that was delivered as described, we will contest it with the evidence (tracking, proof of delivery and your acceptance of these terms), and we may close your account and refuse future orders. Opening a dispute does not cancel your obligation to pay for goods you received.

    7. All sales are final: cancellations and returns

    Our products are sealed research reagents. Once they leave our control we cannot verify how they have been stored or handled, so they cannot be resold. UK Express orders are packed and dispatched within 24 hours of payment, and Factory Direct orders go to the manufacturer straight away. For these reasons:

    • We do not accept cancellations once an order is paid, or returns, except where the law requires it (section 9) or under a claim we accept (section 8).
    • Change of mind, ordering the wrong item or quantity, a change in your research plans, or no longer needing the goods are not grounds for cancellation, return or refund.
    • Nothing sent back to us without our written agreement will be accepted or refunded.
    • Business buyers: all sales are final, with remedies limited to section 8.

    8. Claims: damaged, missing, incorrect, lost or seized

    Damaged, incorrect or missing items. Report it within 24 hours of delivery (the carrier’s delivery scan, not when we mark the order delivered) through “Problem with this order?” on the order in your Portal, our support page (peptx.co.uk/support) or Support@peptx.co.uk, with:

    • your order reference;
    • photos of the outer parcel on all sides, with the delivery label readable;
    • photos of the inner packaging and every item received, with the vial labels readable.

    We strongly recommend filming the opening of your parcel. Claims raised after 24 hours, or without this evidence, are not accepted (subject to section 9).

    Parcel shown as delivered but not received. Tell us within 24 hours of the delivery scan. First check with neighbours, any safe place, and your building’s reception or security. We will raise it with the carrier, which requires you to sign its declaration of non-receipt. A parcel the carrier confirms was delivered to the address you gave us counts as delivered. We replace it only where the carrier’s investigation confirms it was lost or delivered elsewhere.

    Lost in transit. If tracking shows no movement for 5 working days, tell us. We open an investigation with the carrier and replace the order once the carrier confirms it is lost.

    Customs seizure. If customs seize, destroy or return an order sent to a destination we ship to, send us the customs notice within 14 days and we will reship the affected items once, free of charge. A further seizure to the same address is not covered, and we may stop shipping to that address. Seizures are not refunded in cash.

    Wrong address. You must give a complete and accurate delivery address. Parcels delivered to the address you gave, or returned because it was wrong or incomplete, are not our responsibility, and any reshipment is at your cost.

    Purity. Claims that a product is below its stated guaranteed minimum purity are handled under our Purity Guarantee, within 14 days of delivery.

    How claims are settled. We check every claim against our packing records and the carrier’s tracking and proof of delivery. For an accepted claim we replace the affected items. We refund them, to the original payment method, only if we cannot replace them within a reasonable time. We may ask you to return a damaged or incorrect item first, at our cost.

    We record every claim. A claim that is false, exaggerated or unsupported is refused. Repeated or suspicious claims can lead to your account being closed and future orders refused, and suspected fraud may be reported to the carrier, the payment provider and the police.

    9. Your statutory rights

    If you buy as a consumer, the law gives you rights that these terms do not take away. In particular:

    • Faulty or not as described. Under the Consumer Rights Act 2015, goods must be as described, of satisfactory quality and fit for purpose. If they are not, you are entitled to a remedy.
    • Cancelling a distance purchase. Under the Consumer Contracts Regulations 2013 you may cancel within 14 days of delivery. This right ends as soon as a vial’s seal or the tamper-evident packaging is broken: our products are sealed goods that cannot be returned once unsealed, for health protection and hygiene reasons. To cancel, tell us in writing (contact page or Support@peptx.co.uk) within 14 days of delivery, then return the items unopened, unused and in their original sealed packaging within 14 days of telling us, at your own cost and by a tracked service. We refund the price of the returned items, and the standard outbound delivery charge if you return the whole order, within 14 days of receiving them, less any loss in value from handling beyond what is needed to inspect them. Items that come back opened or with a broken seal are not refunded and will be sent back to you at your cost.
    • A consumer may also cancel before dispatch and receive a full refund. UK Express orders are usually dispatched within 24 hours, so in practice this window is short.

    Nothing in these terms affects your statutory rights.

    10. Our liability

    • Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be limited or excluded by law.
    • We are not responsible for: any use of the products outside laboratory research; importing, holding or using them where that is restricted or not allowed; customs action; or delays caused by carriers, customs or events outside our control.
    • For business buyers: we are not liable for loss of profit, revenue, data, research time or business, or any indirect or consequential loss, and our total liability for an order is limited to the price paid for it. You indemnify us against claims, losses and costs arising from your use, onward supply, repackaging or relabelling of the products, or your breach of section 3.
    • For consumers: we are responsible for loss that is a foreseeable result of our breaking these terms, as the law provides.

    11. Delivery, risk and ownership

    • Delivery times are estimates, not guarantees.
    • Risk in the goods passes to you on delivery to the address you gave us. Ownership passes to you once we have received full payment.
    • We do not ship to Russia, Belarus, Mexico, the Caribbean, Central America, South America, China, Hong Kong, India, Pakistan, Turkey, Israel, or any country in Africa. Orders for these destinations are cancelled before dispatch and refunded in full.

    12. Content and intellectual property

    Everything on this site, including text, images, product descriptions and pricing data, belongs to PX Reagents Ltd or its licensors and may not be copied or reused without our written permission.

    13. Changes, law and disputes

    • We may update these terms. The version published when you place an order applies to that order.
    • These terms are governed by the law of Scotland and disputes go to the Scottish courts. If you are a consumer living elsewhere in the UK, you may also bring proceedings in your local courts.
    • Please contact us first through our contact page or at Support@peptx.co.uk. Typical response: under 24 hours.

    14. Your data
