  • Not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition.
  • Not intended for use as food, drugs, dietary supplements, medical devices, or active pharmaceutical ingredients.

Nothing on this website should be interpreted as medical advice, dosage guidance, treatment advice, or a recommendation for human or animal use.

3. Customer Representations

By placing an order, you represent and warrant that:

  1. You are purchasing solely for lawful laboratory research.

  7. The information you provide during checkout is complete and accurate.

We may refuse, cancel, limit, or investigate an order if we reasonably suspect misuse, fraud, unlawful activity, inaccurate information, or a violation of these Terms.

4. Product Information

We make reasonable efforts to present product names, descriptions, images, availability, and documentation accurately. However, minor differences may occur, and website information may be corrected or updated without notice.

Product information is provided for general research and identification purposes only. It is not medical, clinical, pharmaceutical, or professional safety advice.

Researchers are responsible for independently determining whether a product, method, application, storage condition, or protocol is appropriate for their intended lawful research.

5. Certificates of Analysis

When available, Certificates of Analysis (“COAs”) provide information concerning a particular product batch or lot. Customers are responsible for matching the lot number on the product with the corresponding COA.

A COA applies only to the identified batch and should not be interpreted as:

  • Approval for human or veterinary use.
  • Evidence of clinical safety or effectiveness.
  • Medical or dosage guidance.
  • Authorization for an unlawful or unauthorized application.

Please contact support@paynbioscience.com if you cannot locate the appropriate COA.

6. Accounts and Account Security

You may be required to create an account to access certain website features. You are responsible for:

  • Providing accurate and current information.
  • Maintaining the confidentiality of your login credentials.
  • Restricting access to your account.
  • Notifying us promptly of unauthorized account activity.

You are responsible for activities conducted through your account unless prohibited by applicable law.

We may suspend or terminate accounts that violate these Terms, create security risks, or appear to be used unlawfully.

7. Orders and Acceptance

Submitting an order does not guarantee acceptance. An order becomes accepted when we confirm it or begin processing it.

We reserve the right to:

  • Refuse or cancel an order.
  • Limit purchase quantities.
  • Correct pricing or product-information errors.
  • Request identity, age, payment, or intended-use verification.
  • Decline orders associated with suspected fraud, misuse, resale, or unlawful activity.

If we cancel an order after receiving payment, we will issue any refund required by applicable law and our published policies.

8. Prices, Payments, and Taxes

Prices are displayed in the currency shown during checkout and may change without notice.

You agree to pay all product prices, shipping charges, taxes, and other charges displayed before completing your purchase. Available payment methods may change and will be shown during checkout.

You represent that you are authorized to use the payment method submitted with your order. We may use third-party payment processors, whose separate terms and privacy practices may apply.

You are responsible for any applicable customs duties, import fees, taxes, permits, or brokerage charges unless otherwise stated.

9. Shipping and Delivery

Shipping estimates are not guaranteed delivery dates. Delivery may be affected by carrier operations, weather, customs processing, holidays, supply conditions, incorrect addresses, or events outside our reasonable control.

Customers are responsible for:

  • Providing an accurate and deliverable shipping address.
  • Monitoring tracking information.
  • Confirming that the products can lawfully be received in the destination jurisdiction.
  • Paying applicable customs duties, import taxes, and related charges.

Our shipping practices are further described in our Shipping Policy. If these Terms conflict with rights that cannot legally be waived, those statutory rights will control.

10. Returns, Replacements, and Refunds

Eligibility for returns, replacements, cancellations, and refunds is governed by our Returns Policy.

Due to the nature of laboratory research materials, certain products may be ineligible for return after shipment or delivery. Do not return any product without receiving instructions from Payn Bioscience.

Nothing in these Terms limits refund or cancellation rights that cannot legally be waived.

Products should be handled only by appropriately trained individuals in suitable laboratory environments using appropriate protective equipment, containment systems, procedures, and documentation.
