Terms & Conditions

Last updated: April 2025 Applies to: All purchases from Optimus Peptides

Please read these Terms and Conditions carefully before placing an order with Optimus Peptides. By placing an order, you confirm that you have read, understood, and agree to be bound by these Terms in their entirety. If you do not agree with any part of these Terms, you must not place an order.

1. About Us

Optimus Peptides ("we", "us", "our") is a supplier of research-grade peptide compounds for scientific and laboratory research purposes. These Terms govern the sale of products through our website and any other sales channel operated by us.

2. Research Use Only - Critical Restriction

All products sold by Optimus Peptides are strictly intended for in-vitro scientific research and laboratory use only. By placing an order you unconditionally confirm and warrant that:

  • You are a qualified researcher, scientist, or representative of a licensed research institution;
  • You will use the products solely for lawful in-vitro scientific research purposes;
  • The products will not be used for human or veterinary administration, self-administration, diagnosis, treatment, or prevention of any medical condition;
  • The products will be handled in accordance with all applicable health and safety regulations for research chemicals;
  • You have verified that the purchase and use of the product is lawful in your jurisdiction.

Any order placed where we have reasonable grounds to believe these conditions are not met may be cancelled without refund. We reserve the right to refuse service to any person at our absolute discretion.

3. Eligibility to Purchase

You must be aged 18 or over to place an order. By placing an order you confirm that you meet the minimum age requirement and that you are purchasing for legitimate research purposes as described in clause 2.

4. Product Information

We make every reasonable effort to ensure that product descriptions, purity data, and specifications on our website are accurate and up to date. However, we do not warrant that all information is complete, error-free, or current at all times. Product specifications may change between batches; the Certificate of Analysis for your specific batch is the authoritative document for purity and identity.

Placeholder prices displayed on the website are indicative only. Final prices will be confirmed when our team contacts you to process your order. We reserve the right to amend prices at any time without prior notice.

5. Ordering Process

Submission of an order via our website constitutes an offer to purchase, not a binding contract. A contract is formed only upon our acceptance of your order, evidenced by a written order confirmation from us. We reserve the right to decline any order for any reason, including (without limitation) stock availability, suspected misuse, or inability to verify the purchaser's identity.

6. Payment

Payment is due in full before dispatch. Accepted payment methods include bank transfer, Pay by Bank, and cryptocurrency. All prices are in pounds sterling (GBP) unless otherwise stated. For international orders, the buyer is responsible for any currency conversion costs, bank charges, or import duties levied in their jurisdiction.

7. Delivery

We aim to dispatch confirmed orders on the same working day (for orders confirmed before 12:00 GMT). Delivery timescales are estimates only and we accept no liability for delays caused by courier services, customs authorities, or other factors outside our reasonable control. Risk in the goods passes to you upon delivery. For full delivery terms see our Shipping Policy.

8. Returns & Refunds

Due to the nature of research peptide products (temperature-sensitive biological compounds), we are unable to accept returns of opened or used products. We will offer a replacement or full refund in the following circumstances:

  • The product arrives damaged due to a fault in our packaging;
  • The product supplied does not match the product ordered;
  • The product fails to meet the purity specification stated on the Certificate of Analysis.

Any claim must be made within 48 hours of delivery by contacting us with your order number, batch number, and supporting evidence (photographs where applicable). We reserve the right to request return of the product before issuing a replacement or refund. Refunds are issued to the original payment method within 5–10 working days of approval.

9. Liability

To the maximum extent permitted by applicable law, Optimus Peptides shall not be liable for any loss, injury, damage, or harm arising from:

  • The use, misuse, or improper storage of any product purchased from us;
  • Human or veterinary administration of any product, which is strictly prohibited;
  • Any reliance on information provided on our website;
  • Any indirect, consequential, special, or incidental loss or damage.

Our total liability to you in connection with any order shall not exceed the value of that order. Nothing in these Terms shall limit our liability for death or personal injury caused by our negligence, fraud, or fraudulent misrepresentation, or any other liability that cannot be limited by law.

10. Intellectual Property

All content on this website, including but not limited to text, product descriptions, images, logos, and design elements, is the property of Optimus Peptides and is protected by applicable intellectual property laws. You may not reproduce, distribute, or use any content from this website without our prior written consent.

These Terms and any dispute arising from or in connection with them shall be governed by and construed in accordance with the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
