Terms of Service

Last updated: 23 October 2026

1. Introduction

These Terms of Service govern the use of the G11 Peptides website and the purchase of products supplied by G11 Peptides ("we", "us", "our").

By using our website, you agree to the applicable website-use provisions. By placing an order, you agree to the contractual terms applicable to your purchase.

Nothing in these Terms excludes or restricts any right or remedy that cannot lawfully be excluded.

2. Strictly for Laboratory Research Only

All products are supplied strictly for legitimate laboratory research, analytical testing and scientific evaluation.

Permitted applications may include in-vitro research, laboratory testing, analytical reference work and lawful non-clinical scientific evaluation.

Products are not intended, marketed or supplied for:

• Human consumption, injection or administration.

• Veterinary consumption, injection or administration.

• Medical, therapeutic or clinical use.

• Diagnosis, prevention or treatment of disease.

• Use as medicines or pharmaceutical preparations.

• Dietary supplement, cosmetic, household or recreational use.

• Any unlawful or otherwise prohibited application.

Products are intended to be handled by suitably trained and competent persons using appropriate laboratory facilities, equipment and safety procedures.

We make no representation that products are sterile, injectable, clinically approved or suitable for human or veterinary administration.

3. No Medical Advice

Website information, product descriptions, technical specifications and scientific references are provided for research information purposes.

We do not provide medical or veterinary advice, treatment recommendations, dosing instructions for human or animal use, or assurances of clinical safety or effectiveness.

Scientific information must not be interpreted as authorisation for an application outside the stated research purpose.

4. Purchaser Eligibility

Customers must be at least 18 years old.

By placing an order, you confirm that:

• You are at least 18 years old.

• You understand the products' research-only designation.

• You do not intend to use products for human or veterinary administration.

• You have suitable knowledge and arrangements for the intended lawful research activity.

• Your purchase and intended use comply with applicable laws.

• Your order information is accurate.

We may request reasonable verification of age, identity, professional status or research purpose.

We may decline orders before acceptance where there are reasonable grounds to suspect fraud, unlawful activity, prohibited use or failure to satisfy legitimate purchasing requirements.

A research-use declaration does not automatically determine whether a purchaser is legally a consumer or business customer.

5. Customer Responsibilities

Customers are responsible for lawful research activities and appropriate handling, storage, transport and disposal of products after delivery and the lawful transfer of risk.

Customers must comply with applicable safety, import, licensing and regulatory requirements.

We are not responsible for loss or deterioration to the extent established to have been caused by customer misuse, unsuitable storage, improper handling or another matter for which we are not legally responsible.

This does not exclude responsibility for products that were faulty, misdescribed or otherwise nonconforming when supplied.

6. Product Information

We take reasonable care to describe products accurately.

Research materials may exhibit variations in appearance or physical characteristics where consistent with the agreed description and applicable quality requirements.

Variations do not excuse defective, misdescribed or nonconforming goods.

Product photographs may be illustrative unless expressly stated otherwise.

We may correct website errors or change product listings, but changes do not retrospectively alter existing contracts without a lawful basis.

Products are subject to availability.

7. Orders and Acceptance

Placing an order constitutes an offer to purchase.

An automated acknowledgement confirms receipt but does not necessarily constitute acceptance.

A contract is formed when we expressly accept the order or dispatch the goods, whichever occurs first, unless an earlier acceptance is clearly communicated.

Before acceptance, we may decline an order for legitimate reasons, including unavailability, suspected fraud, prohibited use, regulatory restrictions, delivery limitations or an obvious listing error.

If payment has been taken for an order that is not accepted, we will refund it without undue delay.

Accepted orders will be fulfilled unless cancellation or another change is permitted by the contract or applicable law.

8. Prices and Payment

Prices, applicable taxes and delivery charges are displayed before an order is submitted.

Payment must be made using an accepted payment method.

We may undertake reasonable transaction verification and fraud-prevention checks.

No undisclosed additional charges will be imposed.

9. Delivery

Delivery services, charges and estimates are explained in our Shipping Policy and at checkout.

For consumer purchases, risk generally remains with us until the goods come into the physical possession of the customer or their identified recipient, subject to statutory exceptions.

We retain responsibility for delivery failures where the law places that responsibility on us.

Nothing in these Terms restricts statutory remedies for delayed, lost, damaged or undelivered goods.

10. International Orders

International orders may be accepted by request, subject to applicable legal, regulatory and courier requirements.

Customers are responsible for meeting applicable destination-country import requirements and paying properly disclosed import duties, taxes and clearance charges unless otherwise agreed.

We remain responsible for our own legal and contractual obligations.

Customs delays, rejection or seizure do not automatically eliminate refund rights. Responsibility depends on the circumstances and applicable law.

11. Storage, Handling and Product Integrity

Products must be stored and handled in accordance with relevant product information and appropriate laboratory practices.

We are not responsible for deterioration or contamination to the extent established to have resulted from customer-caused improper handling, storage, alteration or unauthorised use.

We may reasonably investigate product-quality complaints and request relevant information or inspection of affected goods.

Neither a customer allegation nor an assumption of improper handling conclusively determines whether goods were defective when supplied.

Statutory rights remain unaffected.

12. Complaints and Quality Investigations

Report product concerns to info@g11peptides.co.uk with your order number and a description of the issue.

We may request reasonable evidence, photographs, relevant factual information or an opportunity to inspect affected goods.

Customers should retain affected products and packaging where reasonably possible.

Claims will not automatically be rejected solely because particular evidence is unavailable.

Where goods fail to conform to the contract, we will provide the remedies required by law.

13. Returns and Cancellation

Our Refunds & Returns Policy explains cancellations, returns, refunds and defective-goods remedies.

We do not offer additional voluntary change-of-mind returns unless expressly agreed.

Eligible consumers may have statutory distance-selling cancellation rights, generally exercisable within 14 days after receipt, subject to applicable conditions and exemptions.

Opening or using goods may affect certain cancellation rights or diminished-value assessments, but does not automatically remove statutory remedies for goods that were faulty when supplied.

14. Prohibited Uses

Products must not be used for human or veterinary administration, unlawful manufacture or distribution, or any other prohibited application.

We do not authorise the preparation, marketing or use of our products for unauthorised clinical, therapeutic or cosmetic purposes.

We are not responsible for harm caused by prohibited or improper use to the extent that we are not legally liable for it.

Nothing excludes liability that cannot lawfully be excluded.

15. Liability

Nothing in these Terms excludes or restricts liability for:

• Death or personal injury caused by negligence.

• Fraud or fraudulent misrepresentation.

• Mandatory statutory consumer rights.

• Any other liability that cannot lawfully be excluded.

For consumers, we are responsible for foreseeable loss or damage caused by our breach of contract or failure to exercise reasonable care and skill, as required by law.

We are not responsible for losses for which we are not legally liable.

Any limitation applicable to genuine business transactions remains subject to applicable legal requirements, including reasonableness where relevant.

16. Business Purchases

A purchase made wholly or mainly for a trade, business, craft or profession may constitute a business-to-business transaction.

Consumer-specific rights do not automatically apply to genuine business transactions.

However, business purchasers retain applicable contractual and statutory rights.

Research-only labelling does not itself determine a purchaser's legal status.

17. Website Conduct

You must not use our website for fraud, unlawful activities, unauthorised access, malicious interference or intellectual property infringement.

We may restrict access or refuse future transactions where reasonably necessary to address genuine security risks, unlawful activity or material breaches.

Accrued rights under existing contracts remain unaffected.

18. Intellectual Property

Original website text, images, branding, graphics and other protected content belong to their respective owners.

Unauthorised reproduction or commercial exploitation is prohibited except where permitted by law or with appropriate permission.

19. Third-Party Services

Our online store uses Shopify and relevant third-party providers for ecommerce, payments, security and related services.

Additional third-party terms may apply to services provided directly by those organisations.

Those terms do not override our legal responsibilities as the seller.

Personal information is handled as described in our Privacy Policy.

20. Website Availability

We take reasonable steps to maintain website availability and security.

Temporary interruptions may occur due to maintenance, technical problems or circumstances outside our reasonable control.

This provision does not remove rights arising under existing contracts.

21. Circumstances Outside Our Control

Where events genuinely outside our reasonable control delay performance, we will take reasonable steps to minimise disruption.

Customers retain statutory delivery, cancellation and refund rights where applicable.

22. Changes to Terms

We may update these Terms for future use.

Changes do not automatically apply retrospectively to existing purchase contracts or remove accrued rights.

The terms applicable to a purchase are generally those in force when the contract was formed, subject to lawful subsequent changes.

23. Complaints and Disputes

Complaints should be sent to info@g11peptides.co.uk.

We will consider complaints fairly and may request information reasonably necessary to investigate.

Customers retain their rights to obtain independent advice and pursue available legal remedies.

Where legally required, information about applicable alternative dispute resolution arrangements will be provided.

24. Governing Law

These Terms are governed by the laws of England and Wales, subject to mandatory protections applicable to customers.

Consumers in Scotland and Northern Ireland retain applicable mandatory rights and jurisdictional protections.

25. Severability and Other Policies

If a provision is unenforceable, the remaining provisions continue to apply where legally possible.

These Terms should be read with our Shipping Policy, Refunds & Returns Policy, Privacy Policy and applicable pre-contract product information.

Mandatory legal rights take precedence over inconsistent contractual provisions.
