Frequently Asked Questions
At Clinical Peptides, transparency is our priority. Below you’ll find answers to the most common questions about our products, shipping, and payments.
What are peptides used for?
Peptides are short chains of amino acids — the same building blocks that make up proteins. Think of them as mini-proteins that can act like signals or messengers in your body, telling cells what to do. Because they’re smaller, they can be absorbed more easily and often act faster than full proteins.
They’re used for a wide range of medical, cosmetic, and performance purposes depending on the type of peptide.
Please note: our peptides are sold strictly for research purposes only.
Are your peptides lab tested?
Yes. All Clinical Peptides products undergo third-party laboratory testing to ensure accuracy, purity, and transparency. Certificates of analysis are available on our Lab Results page.
What form do the peptides come in?
All of our peptides come in a vial in lyophilized peptide powder form for long-term stability.
Is bacteriostatic water included?
Bacteriostatic water can be purchased separately through our website. It is not included with orders.
Do you ship in Canada only?
Yes, at this time Clinical Peptides ships exclusively within Canada.
Do you offer free shipping over $99?
Yes. Orders with a subtotal of $99 CAD or more qualify for free shipping across Canada. For orders below $99, a standard flat-rate shipping fee of $15 applies.
How long does shipping take?
All orders are shipped out the next business day (sometimes even the same day). Delivery time is normally 1 to 3 business days depending on your location. We ship via Canada Post Xpresspost.
What is your return/exchange policy?
Due to the nature of our products, we do not accept standard returns or exchanges.
However, we stand behind the quality of our products with our +99% Purity Guarantee. If there is an issue with your order, such as receiving an incorrect item, damage during transit, or a valid purity-related concern, please contact our team immediately at hello@clinicalpeptides.co.uk.
Please include your order number and a brief description of the issue so our team can review your request and work toward an appropriate resolution.

What happens if my package doesn't arrive?
If your package is lost in transit and hasn’t been delivered, we will sent you a replacement. However, if your tracking shows delivered, but you never received it, please contact Canada Post immediately and hopefully they can track down your package. We cannot do anything about packages that show as delivered.
What happens if I entered the wrong shipping address?
Unfortunately, we cannot do anything about orders that are shipped to the wrong address due to customer error. If you entered the wrong shipping address and your order has already shipped out, we cannot reship it for you. You will need to place a new order.
If your order has not shipped and you want to update your address, please email us immediately at hello@clinicalpeptides.co.uk
Please make sure to enter the correct address.
What forms of payment do you accept?
We offer secure payments through both credit card and interac e-Tranfer for your convenience.
