Return & Refund Policy

Last updated: 20 August 2026

1. About This Policy

This Return & Refund Policy applies to purchases made through the Peptidera website.

Peptidera is operated by:

PKeps e-commerce
Loenermark 584
1025 TZ Amsterdam
The Netherlands

Dutch Chamber of Commerce (KVK): 98487841
VAT identification number: NL005333123B88

Telephone: +31 6 23619659
Website: https://www.peptidera.com

Nothing in this policy limits any mandatory consumer rights provided by applicable law.

2. Research Use Only

All research peptides and related laboratory products supplied by Peptidera are intended exclusively for legitimate scientific and laboratory research.

Products are not intended for:

Human consumption
Veterinary consumption
Personal use
Self-administration
Therapeutic or diagnostic use
Treatment, prevention or cure of disease

Products must be stored, handled and used in accordance with the information provided on the product page, label and accompanying documentation.

3. Consumer Right of Withdrawal

Consumers purchasing online generally have the right to withdraw from the purchase agreement within 14 days after receiving the order, without giving a reason.

For orders containing multiple products delivered separately, the withdrawal period begins on the day after the final product has been received.

To exercise this right, the consumer must notify Peptidera before the withdrawal period expires by sending an unambiguous statement to:

info@peptidera.com

The notification should include:

Customer name
Order number
Products being returned
Date the order was received
A clear statement that the customer wishes to withdraw from the purchase

The customer may use the withdrawal form included at the end of this policy, but use of that form is not mandatory.

Prior approval from Peptidera is not required to exercise a valid statutory right of withdrawal. Customers are nevertheless strongly advised to contact us before returning anything so that we can provide the correct return instructions.

4. Returning Products After Withdrawal

After notifying Peptidera of the withdrawal, the consumer must return the products within 14 days.

Unless otherwise agreed, returns must be sent to:

PKeps e-commerce / Peptidera
Loenermark 584
1025 TZ Amsterdam
The Netherlands

The customer is responsible for the direct return-shipping costs when exercising the ordinary right of withdrawal.

We strongly recommend using a tracked shipping service. The customer is responsible for proving that the return was sent.

Products must be:

Securely packaged
Returned with all supplied components
Protected against damage during transportation
Accompanied by the order number or sufficient identifying information

Do not send products cash on delivery. Such shipments may be refused.

5. Sealed Products and Exceptions

Certain products may be sealed for genuine health-protection, contamination-control or hygiene reasons.

The statutory right of withdrawal may not apply where:

The product is genuinely unsuitable for return for health-protection or hygiene reasons; and
The product’s protective seal has been broken after delivery.

This exception is only applied when all legal requirements are met. A product is not automatically excluded from return merely because it is a research product.

Customers may inspect the external packaging as reasonably necessary. Breaking a protective vial seal, stopper, cap, tamper-evident closure or sealed internal packaging may make the product unsuitable for resale.

The customer’s rights concerning damaged, defective, contaminated, incorrectly supplied or non-conforming products remain unaffected.

6. Reduction in Product Value

During the withdrawal period, the customer may handle a product only to the extent necessary to establish its nature and characteristics.

The customer may be responsible for a reduction in value caused by handling beyond what would reasonably be permitted when inspecting a product.

This may include:

Damaging the packaging unnecessarily
Breaking a seal where no legal return exception applies
Removing or damaging labels
Improper storage
Contamination
Using or altering the product

Any deduction will be reasonable, proportionate and permitted by applicable law.

7. Refunds After Withdrawal

Following a valid withdrawal, Peptidera will reimburse the payments required by law, including the cost of the least expensive standard delivery method offered for the original order.

Additional delivery costs caused by selecting a more expensive shipping option are not reimbursed.

The refund will be processed within 14 days after Peptidera receives the withdrawal notification. Peptidera may withhold reimbursement until:

The returned products have been received; or
The customer supplies sufficient proof that the products were returned,

whichever occurs first.

Refunds are normally made using the original payment method unless another method is expressly agreed.

The time required for the refund to appear may depend on the customer’s bank or payment provider.

8. Damaged, Incorrect or Incomplete Orders

Customers should inspect their order promptly after delivery.

If an order arrives damaged, incorrect or incomplete, please contact us preferably within 48 hours at:

info@peptidera.com

Please provide:

Customer name
Order number
Description of the problem
Photograph of the complete shipment
Photograph of the shipping package
Photograph of the shipping label
Photograph of the affected product and its label
Photograph of visible damage, where applicable

The 48-hour reporting request helps us investigate the issue quickly. It does not remove or shorten mandatory statutory rights.

Do not discard the product, packaging or shipping label while the investigation is ongoing.

9. Solutions for Damaged or Incorrect Orders

When Peptidera confirms that a product was damaged during transportation, supplied incorrectly, missing or otherwise non-conforming, we will provide an appropriate remedy in accordance with applicable law.

Depending on the circumstances, this may include:

Sending the missing product
Replacing the product
Redelivering the order
Providing a partial refund
Providing a full refund
Another appropriate legal remedy

Peptidera will pay reasonable return costs where a return is required because the product was damaged, incorrect or non-conforming.

We may provide a prepaid return label or reimburse reasonable return-shipping expenses.

10. Suspected Product-Quality Problems

If you believe that a product has a quality, seal, contamination, labelling or batch problem:

Stop handling the product.
Keep the product in the recommended storage conditions.
Preserve the vial, packaging, label and batch information.
Contact info@peptidera.com.
Provide photographs and a detailed description.

Do not return a suspected quality-defective product until Peptidera provides instructions.

Certificates of Analysis relate only to the batches and samples identified in the relevant laboratory report.

11. Lost Shipments

If tracking information indicates that a shipment has not progressed or may have been lost, contact us with your order number.

Peptidera will open an investigation with the delivery carrier where appropriate.

A carrier investigation may take time and Peptidera must be allowed a reasonable opportunity to determine what happened.

If the shipment is confirmed as lost before delivery to the customer, Peptidera will provide an appropriate solution, such as:

Replacement of the order
Redelivery
Refund of the affected products

Mandatory consumer rights remain unaffected.

12. Shipments Marked as Delivered

If tracking shows that a shipment was delivered but the customer cannot locate it, the customer should first:

Check the delivery address
Check the mailbox or designated safe place
Ask household members
Ask neighbours
Check any carrier notification
Contact the carrier where appropriate

The customer must then contact Peptidera promptly.

We may request a written non-receipt declaration or additional information for the carrier investigation.

A delivered tracking status does not automatically end the investigation or remove statutory consumer rights. Each claim is assessed using the available delivery evidence.

13. Incorrect Address or Uncollected Shipment

The customer is responsible for entering a complete and correct delivery address.

If a shipment is returned because the customer:

Provided an incorrect or incomplete address
Failed to collect the shipment
Refused delivery without valid legal grounds
Failed to cooperate with reasonable delivery instructions

Peptidera may deduct reasonable return or reshipping costs where permitted by law.

If the customer requests reshipment, additional shipping charges may have to be paid before the order is sent again.

This does not apply where the failed delivery was caused by Peptidera or the carrier and cannot reasonably be attributed to the customer.

14. Customs and International Returns

International customers are responsible for checking local import laws before ordering.

A customer should not refuse a shipment solely to avoid:

Import duties
Local taxes
Customs fees
Carrier clearance charges

If an international shipment is returned due to unpaid charges, prohibited importation, refusal or failure to provide required information, Peptidera may deduct reasonable direct costs from any refund where permitted by law.

No refund can be guaranteed for products lawfully seized or destroyed by authorities due to circumstances attributable to the customer.

This provision does not limit Peptidera’s obligations where Peptidera knowingly shipped a prohibited product or otherwise failed to comply with applicable law.

15. Order Cancellations

Customers may request cancellation before the order has been dispatched by contacting:

info@peptidera.com

We will attempt to process the cancellation, but it cannot be guaranteed once fulfilment or shipment has begun.

If an order has already been dispatched, a consumer may still have a statutory right of withdrawal after receiving the order.

Refusing delivery is not the recommended method of withdrawal. Contact Peptidera first to receive proper return instructions.

16. Exchanges

Peptidera does not normally offer direct product exchanges.

Where appropriate, the original product will be returned and refunded, after which the customer may place a new order.

If Peptidera supplied the wrong product, we may arrange a replacement directly.

17. Return Shipping Responsibility

For an ordinary withdrawal:

The customer pays the direct return costs.
The customer is responsible for secure packaging.
Tracked shipping is strongly recommended.

For damaged, incorrect or non-conforming products:

Peptidera will provide or reimburse reasonable return shipping where a return is required.
The customer should follow the provided return instructions.

Peptidera is not responsible for damage caused by inadequate return packaging.

18. Refund Method

Approved refunds are normally issued to the original payment method.

If that is technically impossible, Peptidera may request verified information for an alternative refund method.

For security reasons, refunds will not normally be sent to:

An unrelated third party
An unverified account
A different crypto address without additional verification
A payment method unrelated to the original transaction

Peptidera never requires a customer to pay an additional fee merely to receive a legitimate refund.

19. Fraudulent or Abusive Claims

Peptidera may investigate return or refund requests where there is reasonable evidence of:

Fraud
Product substitution
Manipulated photographs
False non-delivery claims
Chargeback abuse
Intentional product damage
Repeated misuse of the return process

We may refuse a claim where reliable evidence demonstrates that it is fraudulent or not legally valid.

This does not limit the rights of customers submitting legitimate claims.

20. Chargebacks and Payment Disputes

Customers are encouraged to contact Peptidera before initiating a chargeback so that we have an opportunity to resolve the issue.

Nothing in this policy prevents a customer from lawfully disputing:

An unauthorized transaction
An incorrect charge
A transaction where legally required remedies were not provided

Peptidera may submit order, delivery and communication records to the payment provider when responding to a payment dispute.
