Shipping & refund policy

Last updated · 5 May 2026

UK shipping

• Standard tracked: £6.99 — 1 to 3 working days from dispatch.
• Free UK shipping: orders over £100.
• Orders placed before 14:00 GMT, Monday to Friday, are dispatched same-day. Orders placed at the weekend or on UK public holidays are dispatched on the next working day.
• All UK orders are sent fully tracked. Tracking links are included in the dispatch confirmation email.

International shipping

International orders are reviewed on a case-by-case basis depending on the destination country and applicable customs and import regulations. Please contact research@zynoxlabs.co.uk with your country and order requirements before placing an international order. The customer is responsible for any customs duties, taxes, or import charges levied by the destination country.

Packaging

Every Zynox Labs shipment is packed in temperature-stable foil-lined transit packaging to protect lyophilised peptides during transit. Outer packaging is plain and discreet — there is no clinical or pharmaceutical branding on the exterior. Vials are individually labelled inside with sequence, lot, expiry, and reconstitution guidance.

Failed deliveries

If a delivery is failed by the courier and the parcel is returned to us, we will contact you to arrange a re-shipment. Re-shipment may incur a second postage charge if the failure was due to incorrect address details or non-collection.

Damaged or incorrect orders

If your order arrives damaged, defective, or contains the wrong item, please email orders@zynoxlabs.co.uk within 7 days of delivery, including:

• Your order reference number (sent in the confirmation email).
• Photographs of the damaged packaging or incorrect item.
• A short description of the issue.

Once verified we will arrange a free replacement or full refund at your preference.

Refunds

Due to the temperature-sensitive and research-grade nature of our products, we are unable to accept returns of opened items. Unopened, sealed vials may be returned within 14 days of delivery for a refund of the product cost (postage is non-refundable). Please contact us before returning any item — unsolicited returns cannot be processed.

Approved refunds are processed back to the original payment method within 5–10 business days. Refund timings beyond this depend on your card issuer.

Order cancellations

You may cancel an order free of charge any time before it has been dispatched. Once dispatched, the order is subject to the refund terms above. To cancel an order please email orders@zynoxlabs.co.uk immediately, quoting your order reference.

Lost parcels

If a tracked UK parcel has not arrived within 10 working days of dispatch, please contact us and we will open an investigation with the courier. Replacement or refund will be issued upon resolution of the courier investigation.
