The terms
of every transaction.

1. Parties

The seller is Meridian Land Ventures LLC, a limited liability company organised under the laws of the State of Delaware, United States of America, trading as Cresten Labs. Full corporate identification, including registered office, file number, federal employer identification number, and authorised signatory, is published on the Imprint page. The buyer is the natural or legal person placing the order through the Cresten Labs website. References in these Terms to "Cresten Labs" or "the seller" mean Meridian Land Ventures LLC.

2. Eligibility to purchase

Orders may be placed only by buyers who confirm at the point of purchase that they are at least 21 years of age and are qualified researchers, registered laboratory operators, institutional buyers, or otherwise lawfully entitled to acquire research compounds in their jurisdiction. The affirmative acknowledgement step at order placement records the buyer’s confirmations of age, research framework, non-therapeutic intent, terms acceptance, and jurisdictional compliance. Cresten Labs may, at its sole discretion, request additional documentation establishing the buyer’s qualification and may decline orders where the buyer’s acknowledgements appear inconsistent with the order pattern.

3. Nature of products

All compounds are research compounds supplied for in-vitro and preclinical research only. They are not medicinal products, dietary supplements, food, cosmetics, or products for human or veterinary use. They have not been approved by any medicines regulator for any clinical indication. The full scope of intended use, restrictions, and buyer affirmations is set out in the Research Use Only declaration, which forms part of these Terms.

4. No warranties beyond stated specifications

The compound supplied is warranted to correspond to the certificate of analysis published for the dispatched batch in respect of identity (LC-MS), purity (HPLC), and the analytical specifications stated on that certificate. No other warranty, express or implied, is given. Cresten Labs makes no warranty of fitness for any particular research purpose, no warranty of suitability for any specific experimental design, no warranty that the compound is safe or appropriate for any application the buyer may contemplate, and no warranty that the compound is fit for use outside the strict in-vitro and preclinical research scope set out in these Terms. The buyer’s research design, methodology, handling, storage after receipt, and downstream interpretation are the buyer’s sole responsibility.

5. Orders, pricing, and stock

Prices are listed in EUR. Stock availability is indicated on each compound’s record page and may be updated in real time. Cresten Labs reserves the right to refuse, modify, or cancel any order in cases of pricing error, stock unavailability, suspected misuse, inconsistency in the buyer’s acknowledgements, or non-compliance with these Terms or the Research Use Only declaration. In any such case, payment will be refunded in full where it has already been collected.

6. Payment

Cresten Labs accepts payment by 3D Secure card (Visa, Mastercard), Bizum, BLIK, SEPA bank transfer, Klarna where available, and USDT-TRC20 (via NOWPayments, with a five percent discount applied at checkout). Payment must be received in full before any order is dispatched. The seller does not retain card details; payment processing is handled by accredited payment service providers acting as data controllers in their own right for the data they process.

7. Delivery

Orders ship from a fulfilment partner located within the European Union to selected EU markets, by InPost, Packeta, or DPD locker pickup or address delivery. Estimated delivery time within the EU single market is two to five business days from dispatch. Cresten Labs is not liable for delays caused by carriers, customs authorities, or events outside its reasonable control (see Section 14, Force Majeure).

Cresten Labs ships to a defined list of EU member states in the current operating phase. The full served list with transit times is on the Shipping page. Where the checkout does not list a country, an order cannot currently be placed and no payment is taken. Markets outside the current operating phase are added as carrier integrations and operational requirements for each market are completed.

8. Quality and certificates

Every batch is tested by an accredited third-party analytical laboratory. The certificate of analysis for each batch is published on the compound’s record page before it lists for sale and is included with each shipment. Cresten Labs warrants that the compound supplied corresponds to the certificate published for the batch dispatched, within the analytical tolerance of the methods used.

9. Returns and statutory right of withdrawal

Because of the nature of research compounds, opened or partially used compounds cannot be returned for hygiene and integrity reasons (Article 16(e) of EU Directive 2011/83/EU on consumer rights, where applicable to the buyer). Unopened, sealed vials may be returned within fourteen days of receipt for a full refund of the product cost (return shipping is not refunded), where the seal and label are intact and the buyer can demonstrate that the storage conditions specified on the certificate were maintained. This fourteen-day window is the statutory right of withdrawal under Directive 2011/83/EU on consumer rights, where the directive applies. Where a compound is found to be non-conforming on accredited re-verification, Cresten Labs will replace the batch or refund the order in full at its discretion.

10. Restriction on resale and redistribution

The buyer agrees that the compound is supplied for the buyer’s own research use only. The buyer shall not resell, redistribute, transfer, or supply the compound to any third party, whether for consideration or otherwise, without the prior written consent of Cresten Labs. The buyer shall not repackage, relabel, or remove batch identification from the compound. The buyer shall maintain the compound in its original packaging with original certificate documentation until the compound is consumed in the buyer’s research workflow. Breach of this section voids the warranty in Section 8 and the right of withdrawal in Section 9, and may give rise to indemnification obligations under Section 13.

11. Restriction on therapeutic and consumer use

The buyer represents and warrants that the compound will not be administered to humans or animals for therapeutic, medicinal, cosmetic, performance-enhancement, or any other consumer purpose. The buyer represents and warrants that the compound will not be incorporated into any product offered to the public, prescribed, dispensed, or otherwise used outside an in-vitro or preclinical research context. The buyer assumes full responsibility for any consequences arising from any use of the compound outside these restrictions, including but not limited to physiological harm, regulatory consequences, and third-party claims. Cresten Labs accepts no liability for any such use.

12. Limitation of liability

To the fullest extent permitted by applicable law, the seller’s aggregate liability arising from or relating to any order, these Terms, the Research Use Only declaration, the Privacy Policy, the website, or any compound supplied, whether in contract, tort (including negligence), strict liability, or otherwise, is limited to the price actually paid by the buyer for the specific order giving rise to the claim.

The seller shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including without limitation damages for lost profits, lost revenue, lost data, lost research time, lost research opportunity, business interruption, reputational harm, regulatory consequences, or any other commercial or non-commercial loss, even if the seller has been advised of the possibility of such damages.

Nothing in these Terms limits liability for: (a) fraud or fraudulent misrepresentation; (b) gross negligence or wilful misconduct; (c) death or personal injury caused by the seller’s negligence; or (d) any liability that cannot be excluded or limited under the mandatory law applicable to the buyer.

13. Buyer indemnification

The buyer shall indemnify, defend, and hold harmless the seller, Meridian Land Ventures LLC, and its members, managers, employees, contractors, and agents from and against any and all claims, demands, actions, proceedings, liabilities, losses, damages, costs, and expenses (including reasonable attorneys’ fees) arising from or relating to: (a) the buyer’s breach of these Terms or the Research Use Only declaration; (b) the buyer’s use, misuse, modification, redistribution, resale, or disposal of any compound supplied; (c) any administration of any compound to humans or animals by the buyer or by any party to whom the buyer transferred the compound; (d) any third-party claim arising from any of the foregoing; and (e) any breach of the buyer’s representations and warranties under these Terms.

14. Force majeure

The seller shall not be liable for any failure or delay in performance under these Terms caused by circumstances outside the seller’s reasonable control, including without limitation: acts of God, natural disasters, pandemic or epidemic, war, civil unrest, terrorism, government action, regulatory change, customs delays or seizures, carrier failures, payment processor terminations, supplier failures, supply chain disruption, labour disputes, fire, flood, power failures, telecommunications or internet outages, and cyber-attacks. Where such circumstances affect performance for more than thirty consecutive days, either party may terminate the affected order and the seller will refund any payment received for items not yet dispatched.

15. Individual dispute resolution and class-action waiver

Each dispute, claim, or controversy arising out of or relating to these Terms or any order shall be resolved on an individual basis only. The buyer agrees that no claim shall be brought, prosecuted, or maintained as a class action, collective action, mass action, consolidated proceeding, representative action, or in any other form of aggregate proceeding. No arbitrator or court shall have authority to consolidate the claims of multiple buyers or to preside over any form of class or collective proceeding. This Section 15 does not apply to the extent that mandatory consumer protection law in the buyer’s jurisdiction prohibits the waiver of class actions; in such jurisdictions, this Section 15 applies only to the extent permitted.

16. Governing law and disputes

These Terms are governed by the laws of the State of Delaware, United States of America, without regard to conflict of law principles. The seller, Meridian Land Ventures LLC, is a Delaware limited liability company. Any dispute arising from or in connection with these Terms or any order placed with Cresten Labs that cannot be resolved by the parties through good-faith negotiation will be referred to binding arbitration under the rules of the American Arbitration Association, seated in Wilmington, Delaware. The language of arbitration is English.

Where the buyer is a consumer resident in the European Union, the foregoing choice of law and forum does not deprive the buyer of the protection afforded by mandatory provisions of the law of the buyer’s habitual residence (per Article 6 of EU Regulation 593/2008, Rome I). EU consumer buyers retain the right to bring disputes before the courts of their habitual residence under EU Regulation 1215/2012 (Brussels I recast), and may use the European Online Dispute Resolution platform at ec.europa.eu/consumers/odr.

17. Severability and entire agreement

If any provision of these Terms is held by a court or arbitrator of competent jurisdiction to be invalid, illegal, or unenforceable, that provision shall be enforced to the maximum extent permitted, and the remaining provisions shall remain in full force and effect. The invalidity of any single provision does not invalidate any other provision or these Terms as a whole.

These Terms, the Research Use Only declaration, the Privacy Policy, the Imprint, the Cookie Policy, and the affirmative acknowledgements recorded at order placement constitute the entire agreement between the buyer and the seller in respect of any order, and supersede any prior representations, understandings, or agreements, whether oral or written, on the subject matter.

18. Notice of changes

Cresten Labs may update these Terms from time to time. The version effective at the time an order is placed governs that order. Material changes will be notified through a banner on the website with a thirty-day notice period before taking effect, and through the Cresten Labs newsletter where the buyer has subscribed. Continuing to place orders after notice of material changes constitutes acceptance of the updated Terms.

19. Authoritative language

The authoritative version of these Terms is the English-language version. Translations are provided for the buyer’s convenience. In the event of any conflict, ambiguity, or inconsistency between the English version and a translation, the English version controls.

20. No assignment by buyer

The buyer may not assign, transfer, or sub-license its rights or obligations under these Terms without the seller’s prior written consent. The seller may assign its rights and obligations under these Terms in connection with a merger, acquisition, sale of substantially all of its assets, or by operation of law, without the buyer’s consent.
