Frequently Asked Questions

Ordering & Payment

What payment methods do you accept?

We accept Visa, Mastercard, American Express, Apple Pay and Google Pay. Payments are processed securely at checkout and charged in the currency of your region: GBP for the UK, EUR for Europe and USD for the United States.

How do discount codes work?

Enter your code in the promo box at checkout and the discount is applied before payment. One code can be used per order. The free delivery threshold is worked out on your total after the discount.

Can I change or cancel my order?

Email support@pristinepeptides.co.uk with your order number as soon as possible. If your order has not been dispatched yet we can usually change or cancel it. Once it has been handed to the courier it can no longer be changed.

Delivery

When will my order arrive?

Orders placed before 3pm Monday to Friday are dispatched the same day by Royal Mail First Class, for next business day delivery in the UK. Europe takes 7–10 business days and the United States 5–7 business days, both fully tracked.

How much does delivery cost?

UK delivery is £5.99, free on orders over £60. Europe is €17.99, free over €120. The United States is $19.99, free over $180.

How do I track my order?

A tracking link is emailed to you as soon as your shipping label is created. If you cannot find it, check your spam folder or use our Track Order page with your order number.

Is the packaging discreet?

Yes. Every order ships in plain, nondescript outer packaging with no mention of peptides, research chemicals or Pristine Peptides.

Testing & Certificates

How pure are your compounds?

Every batch is independently tested by HPLC and guaranteed at 99% purity or higher. The full certificate of analysis for each batch is published on our Lab Results page.

How do I find the certificate for my vial?

Your batch number is printed on the vial label. Search for it, or the compound name, on our Lab Results page to open the certificate for that exact batch.

Storage & Handling

How should I store my vials?

Lyophilised (freeze-dried) vials keep best in a freezer at -20°C for long-term storage. Once reconstituted, keep them refrigerated at 2–8°C and use them within a short period.

What do I need to reconstitute a vial?

Vials are supplied as a lyophilised powder and need to be reconstituted with bacteriostatic water, which we sell separately. Our reconstitution calculator works out the volumes for you.

Returns & Support

What if my order arrives damaged or incorrect?

Email support@pristinepeptides.co.uk within 14 days of delivery with your order number and a photo of the problem. Damaged, defective or incorrect items are replaced or fully refunded, and we cover the return postage.

Can I return an item I no longer need?

Unopened, factory-sealed vials in their original packaging can be returned within 14 days. Contact us before sending anything back. Vials with a removed or tampered cap cannot be returned, and return postage for unwanted items is paid by you.

Are your products for human use?

No. All Pristine Peptides products are sold strictly for laboratory and in-vitro research. They are not intended for human or animal consumption, or for diagnostic or therapeutic use.
