At Longevity Box, we stand behind three distinct guarantees:
-
The Purity Challenge
-
The 60-Day Promise
-
The 700-Day Potency & Purity Guarantee
Each guarantee has a different purpose and a different claims process. These terms explain how each one works.
These guarantees are offered by Longevity Box Ltd and apply in addition to your normal statutory rights. Nothing in these terms affects your legal rights as a consumer.
1. General terms
1.1 Who these guarantees apply to
These guarantees apply to retail customers who purchase directly from the official Longevity Box website, unless stated otherwise.
1.2 Proof of purchase
To make any claim under any guarantee, you must provide valid proof of purchase from Longevity Box.
1.3 One guarantee per issue
The same issue cannot be claimed under more than one guarantee. If more than one guarantee appears relevant, Longevity Box will decide which guarantee applies.
1.4 Non-transferable
Guarantees apply only to the original purchaser and may not be transferred to another person.
1.5 Abuse or misuse
Longevity Box reserves the right to reject claims that are fraudulent, abusive, misleading, incomplete, or made in bad faith.
1.6 How to contact us
To make a claim, please contact: [insert customer support email]
Please include your order number and the name of the relevant guarantee in the subject line where possible.
2. The Purity Challenge
2.1 What The Purity Challenge is
The Purity Challenge applies where Longevity Box states that a qualifying product is the only excipient-free product of its kind on the market, or uses similar comparative purity language.
If you buy a qualifying competing product with a cleaner label than ours, and you provide the required evidence within the claim period, we will refund the full amount you paid us for the relevant qualifying Longevity Box product.
You keep both products.
2.2 Products covered
The Purity Challenge applies only to products where the challenge is expressly shown on the relevant product page at the time of your purchase.
2.3 What “cleaner” means
For the purpose of The Purity Challenge, a competitor product will only be treated as “cleaner” if:
-
it is a genuinely comparable product in the same category;
-
it is sold to consumers in the same market covered by the claim;
-
its label shows fewer non-active ingredients than the relevant Longevity Box product; and
-
that comparison is made using the competitor product’s own published label information.
Where needed, Longevity Box may assess comparability by reference to:
-
product type
-
active ingredient or primary use case
-
serving format
-
serving basis
-
market of sale
-
label presentation
Longevity Box’s decision on whether a competitor product is genuinely comparable will be made reasonably and in good faith.
2.4 Evidence required
To make a claim under The Purity Challenge, you must provide:
-
proof of purchase from Longevity Box;
-
proof of purchase for the competing product;
-
a clear image of the competing product label showing the full ingredient list;
-
any serving size information needed to assess the label properly; and
-
any other reasonable supporting information we request to verify the claim.
2.5 Claim window
Claims must be submitted within 90 days of delivery of your Longevity Box order.
2.6 Refund scope
If your claim is valid, we will refund the amount you paid us for the relevant Longevity Box product covered by the challenge.
We do not reimburse:
-
the cost of the competitor product;
-
postage, duties, taxes, or other third-party charges unless required by law;
-
unrelated products in the same order unless we expressly agree otherwise.
2.7 Claim limits
Unless otherwise stated, The Purity Challenge is limited to one valid claim per customer.
2.8 Exclusions
The Purity Challenge does not apply where:
-
the competing product is not genuinely comparable;
-
the claim is based on incomplete, inaccurate, or unreadable label information;
-
the competing product is counterfeit, relabelled, discontinued, or unavailable for reasonable verification;
-
the competing product is sold only in a different market from the claim being assessed;
-
the challenge wording was not active on the relevant product page at the time of purchase;
-
the claim is submitted outside the claim window.
2.9 Our review process
Longevity Box will review all claims reasonably and in good faith. We may request further evidence where needed.
If a claim is approved, the refund will be made to your original payment method wherever possible.
3. The 60-Day Promise
3.1 What the 60-Day Promise is
The 60-Day Promise is our standard satisfaction guarantee. If a qualifying product is not right for you, you may request a refund within 60 days of delivery.
This guarantee exists separately from The Purity Challenge. You do not need to prove anything about a competitor product to use it.
3.2 Products covered
Unless otherwise stated, the 60-Day Promise applies to products purchased directly from the official Longevity Box website.
3.3 Claim window
Claims must be submitted within 60 days of delivery of your order.
3.4 What you need to provide
To make a claim, you must provide:
-
your Longevity Box order number; and
-
confirmation of the product you want refunded.
Longevity Box may ask reasonable follow-up questions to process the claim, but this is a satisfaction promise, not a proof-heavy challenge.
3.5 Return requirements
Unless we tell you otherwise, you do not need to return an empty bottle to start the claim process.
If we do ask for a return in specific cases, we will tell you clearly what is required and by when.
3.6 Refund scope
If your claim is accepted, we will refund the price paid for the relevant product.
Unless required by law, we do not automatically refund:
-
shipping charges;
-
duties or taxes;
-
other external costs not charged by Longevity Box as the product price.
3.7 Reasonable use
The 60-Day Promise is intended for genuine customer use. Longevity Box reserves the right to reject claims where we reasonably believe the policy is being abused.
4. The 700-Day Potency & Purity Guarantee
4.1 What the guarantee covers
The 700-Day Potency & Purity Guarantee applies to qualifying Longevity Box products and means that, when stored correctly and used before the stated expiry period, the product should remain within our stated purity and potency standards for 700 days from the relevant start point described below.
4.2 Start point
Unless otherwise stated on the relevant product page or label, the 700-day period runs from the date of manufacture or batch reference held by Longevity Box for that product.
Where a different start point is commercially clearer for customers, Longevity Box may specify that on the relevant product page.
4.3 Products covered
This guarantee only applies to products that expressly display the 700-Day Potency & Purity Guarantee at the time of purchase.
4.4 Conditions
The guarantee applies only where:
-
the product was purchased directly from Longevity Box or an authorised seller approved by us;
-
the product has been stored in accordance with the storage instructions on the packaging;
-
the product has not been tampered with, misused, or damaged;
-
the batch code remains legible or can otherwise be verified.
4.5 What to do if you think a product has failed
Please contact us and provide:
-
your proof of purchase;
-
product name;
-
batch code;
-
photographs of the packaging;
-
a description of the issue.
Longevity Box may ask for the product to be returned or for additional information if needed to investigate the claim.
4.6 Remedy
If we confirm that a qualifying product did not meet the guaranteed potency or purity standard within the 700-day guarantee period, we may, at our discretion:
-
replace the product;
-
issue store credit; or
-
refund the price paid for the affected product.
4.7 Exclusions
The guarantee does not apply where:
-
the product was stored improperly;
-
the packaging was damaged after delivery;
-
the issue arises from misuse, contamination, or unauthorised resale;
-
the claim cannot be assessed because the batch code is missing or unreadable;
-
the product was used beyond any stated expiry date or outside the guaranteed period.
5. How refunds are made
Where a refund is approved under any guarantee, we will normally refund the original payment method used for the order. If that is not possible, we will agree an alternative refund method with you.
Refund timings can vary depending on your payment provider.
6. Changes to these guarantees
Longevity Box may update these terms from time to time. Any change will apply only to purchases made after the updated terms are published, unless a change is required by law or is clearly more favourable to customers.
The terms in force at the time of your purchase will apply to your order.
7. Statutory rights
These guarantees are offered in addition to your legal rights under applicable consumer law. Nothing in these terms limits or excludes those rights.
