Terms of Service

These Terms of Service ("Terms") govern your access to and use of the Yield N Helix website and your purchase of products. By using this site or placing an order, you agree to these Terms.

1. Research use only

All products are sold strictly for laboratory and research use only and are not for human or veterinary consumption. Your purchase is subject to our Research Use Only Policy, which is incorporated into these Terms by reference.

2. Eligibility

You must be at least 21 years of age and legally permitted to purchase research materials in your jurisdiction. By ordering, you represent that you meet these requirements and that all information you provide is accurate.

3. Orders and pricing

All orders are subject to acceptance and availability. Prices are shown in U.S. dollars and may change without notice. We reserve the right to correct pricing errors, limit quantities, and refuse or cancel any order at our discretion. Order totals, including shipping, are calculated and confirmed by us at checkout; any amounts displayed before that are estimates.

4. Payment

Payment is due at the time of order via the methods offered at checkout. For manual payment methods, your order is reserved as pending until payment is received and confirmed. We do not store card or cryptocurrency credentials; hosted payment providers process those directly.

5. No medical claims; no advice

Our products are not drugs and have not been evaluated by the FDA. Nothing on this site is intended as medical, legal, or professional advice, and no statement should be construed as a claim that any product is safe or effective for human or animal use.

6. Assumption of risk; responsible use

You assume full responsibility for the lawful and safe handling, storage, use, and disposal of products you purchase, and for compliance with all laws applicable to you. You agree not to use or supply any product for human or animal consumption or any unlawful purpose.

7. Limitation of liability

To the fullest extent permitted by law, Yield N Helix and its suppliers will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any misuse of the products. Our total liability for any claim will not exceed the amount you paid for the product giving rise to the claim.

8. Indemnification

You agree to indemnify and hold harmless Yield N Helix, its officers, employees, and suppliers from any claims, damages, losses, or expenses (including reasonable legal fees) arising out of your misuse of the products, your violation of these Terms, or your violation of any law.

9. Governing law

These Terms are governed by the laws of the United States and the state in which Yield N Helix operates, without regard to conflict-of-laws principles.

10. Changes

We may update these Terms from time to time. Continued use of the site after changes take effect constitutes acceptance of the revised Terms.
