These terms apply when you use the NADFlow website or buy products through it. Please read them before placing an order.

By using the website, you agree to the website-use terms below. When you place an order, we will ask you to confirm that you agree to the terms of sale.

These terms do not affect any consumer rights that cannot legally be excluded or limited.

You can contact us using the customer contact details displayed on the NADFlow website.

In these terms, “we”, “us” and “our” mean Stock Retail Limited trading as NADFlow. “You” and “your” mean the person using the website or placing an order.

3. Products and product information

Products available for purchase are described on the relevant product pages. Please read the product description, instructions and any information shown during checkout before ordering.

We take reasonable care to ensure product descriptions and prices are accurate. If we find a material error, we will contact you before accepting your order. We may correct errors or update product information at any time.

The information on the website is general information. It is not a substitute for advice from a qualified healthcare professional.

4. Questionnaires and product information

Some products may require you to complete a questionnaire before continuing to purchase. You must answer all questions accurately and completely.

Completing a questionnaire does not guarantee that an order will be accepted. If we need more information or cannot proceed with your order, we will contact you.

You must be at least 18 years old to place an order.

5. Orders and contract formation

Product listings on the website are an invitation for you to make an offer to buy. When you place an order, you are making that offer.

After you submit your order, we will send an acknowledgement. This confirms that we have received it; it does not mean that we have accepted it.

A contract is formed when we send you an order confirmation. We may decline an order, for example, if a product is unavailable, the information provided is incomplete, or we are unable to fulfil the order. If payment has already been taken, we will arrange a refund.

Please check your order details before submitting it. Contact us as soon as possible if you notice an error. We cannot guarantee that we will be able to change an order after it has been accepted.

6. Prices and payment

The price, any applicable taxes and delivery charges will be shown before you place your order. The total shown at checkout is the amount payable.

We may change prices or offers at any time. A change will not affect an order we have already accepted.

Payment must be made using one of the payment methods shown at checkout. Payments are processed through the payment provider shown during checkout.

If you believe a payment has been taken in error, contact us using the details on the website. Nothing in these terms removes any rights you may have with your bank, card provider or under consumer law.

7. Delivery

We will deliver your order to the address you provide at checkout. Available delivery options, charges and estimated delivery times will be shown before you place your order.

We will use reasonable efforts to deliver within the stated estimate. If no delivery date has been agreed, we will deliver within 30 days unless we agree a different date with you.

Please check your delivery details carefully. Contact us if your order has not arrived within the stated delivery period.

Risk in the products passes to you when you, or someone you nominate, receives them. Ownership passes when we have received full payment and the products have been delivered.

8. Cancelling an order and returns

If you are a consumer buying online, you can usually cancel your order within 14 days after receiving the products. You do not need to give a reason.

To cancel, contact us with a clear statement that you wish to cancel. You may use any cancellation form we make available, but you do not have to.

After telling us you wish to cancel, return the products within 14 days. Unless we say otherwise, you are responsible for the direct cost of returning them. We will refund the amount due, including the standard delivery charge, using the original payment method. We will make the refund within the time required by law.

You may handle products to inspect them as you would in a shop. If handling goes beyond what is necessary to inspect them and reduces their value, we may make a deduction where the law allows.

The right to cancel may not apply to certain sealed products that cannot be returned for health protection or hygiene reasons once they have been unsealed. If this exception applies to a product, we will explain it before you place your order. This does not affect your rights if a product is faulty or not as described.

9. Faulty or incorrect products

Your statutory rights apply if a product is faulty, unsafe, not as described or does not do what it is supposed to do.

Contact us if there is a problem with your order. Depending on the circumstances and your legal rights, you may be entitled to a repair, replacement, price reduction or refund.

10. Order cancellation by us

We may cancel an order before dispatch if we cannot supply the product, if there has been a material pricing or listing error, or if we have reasonable grounds to believe the order details are inaccurate or fraudulent.

If we cancel an accepted order, we will tell you and refund any payment made for the affected products.

11. Website use

You may use the website for personal, lawful purposes. You must not misuse it, interfere with its security or operation, or use it to submit information that is false, unlawful or harmful.

We may suspend or restrict access to the website when needed for maintenance, security or other operational reasons.

12. Privacy

Our Privacy Policy explains how we collect and use personal information, including information you provide through any questionnaire or order form. Please read it before submitting personal information.

13. Intellectual property and links

The website and its content are owned by or licensed to Stock Retail Limited. You may view and use the content for your personal use. You must not copy, republish or use it commercially without our written permission.

The website may contain links to third-party websites. We are not responsible for their content or services.

14. Our responsibility to you

Nothing in these terms limits or excludes liability where doing so would be unlawful. This includes liability for death or personal injury caused by negligence, fraud, or your statutory consumer rights.

If we fail to comply with these terms, we are responsible for loss or damage that was a foreseeable result of our breach or negligence. We are not responsible for loss or damage that was not foreseeable.

If you buy as a consumer, we supply products for personal use. We are not responsible for business losses arising from your use of the website or products.

15. Changes to these terms

We may update these terms by publishing a revised version on the website. The version in force when you place your order will apply to that order.

16. Complaints

If you have a question or complaint about an order or the website, contact us using the customer contact details displayed on the NADFlow website. We will review your complaint and respond as soon as reasonably possible.

17. Governing law

These terms are governed by the laws of England and Wales.

If you are a consumer living elsewhere in the United Kingdom, you will also benefit from any mandatory protections available under the law of the part of the UK where you live.

18. General

If any part of these terms is found to be unenforceable, the remaining terms will continue to apply.

If we do not enforce a right immediately, that does not mean we have waived it.

These terms, together with the information shown on the relevant product page, at checkout and in our Privacy Policy, form the agreement between you and us for your use of the website and purchase of products.

NADFlow · Before checkout

A few questions before checkout

PART 1 OF 2
01 / 02

Answer a few short questions accurately. You must be 18 or over and completing them for yourself.

Your information: these questions are based on the product’s written safety information. A clear result is not a medical assessment or confirmation that the product is suitable for you.
1. Are you aged 18 or over?
2. Is this product for your own use?

Review each short note, then answer the health questions about yourself. Select Yes only when you understand each safety point and can follow it. If you need advice, checkout pauses so you can ask a qualified healthcare professional.

View key product safety information

Do not use if you are under 18, pregnant or breastfeeding. If you have a medical condition, take prescription medication, are receiving intensive medical treatment, have an allergy, or are unsure whether NAD+ is suitable for you, speak to a qualified healthcare professional before use. Keep the pen refrigerated at 2–8°C, do not freeze it, and refrigerate it promptly on arrival. Dispose of used needles safely in a sharps container. Review the product information on the NADFlow website.

4. Are you pregnant or breastfeeding?

The product information says not to use the product if you are pregnant or breastfeeding.

5. Do you have a medical condition, take prescription medication, or receive intensive medical treatment?

This follows the product information. A “Yes” or “Unsure” answer pauses the purchase journey so you can seek professional advice.

6. Do you have a known allergy to an ingredient, or have you had a reaction to an injectable product?

If yes or unsure, speak with a qualified healthcare professional before continuing.

7. Are you comfortable using an injection pen?

If you are not comfortable, or are unsure, checkout pauses so you can seek guidance.

8. Keep the pen refrigerated at 2–8°C, do not freeze it, and refrigerate it promptly on arrival. Dispose of used needles safely in a sharps container. Do you understand these requirements and have what you need to follow them?

If you do not have refrigeration or a sharps container, or you are unsure, choose No.

9. Have you read the product information and do you confirm that none of its stated exclusions apply to you?

This is a separate eligibility check. Yes means you have read the information and none of its stated exclusions apply to you.

Would you like us to contact you?

Leave your details if you would like NADFlow to follow up. We’ll send only your name, email address and the reason category you choose. Your other questionnaire answers and any optional health details are not sent.
