At PeptidLab, research peptides are prepared and shipped from France. If a product is not suitable or arrives damaged, this page explains how to request a return or a refund.
Right of withdrawal
You have 14 days from receipt to withdraw, without giving a reason, under article L221-18 of the French Consumer Code.
The period starts on the day you, or a third party named by you, take possession of the parcel.
Conditions for accepting a return
A return is accepted only when all of these conditions are met.
- Products in their original packaging, sealed and unused
- Vials intact, protective cap in place
- No sign of opening or handling
- Request sent within 14 days of receipt
Exceptions
Under article L221-28 of the French Consumer Code, the right of withdrawal does not apply to goods unsealed after delivery that cannot be returned for hygiene or health-protection reasons.
This includes the following cases.
- Products whose cold chain has been broken
- Prefilled pens removed from their sterile packaging
- Opened vials or bottles
How to request a return
- Email contact@peptidlab.li with your order number and the reason for the return.
- We reply within 24 business hours with the steps to follow. The return address is given in the reply.
- Send the product back in its original packaging. Do not ship anything before you receive our instructions.
- Once the product has been received and checked, the refund is sent to the payment method used for the order.
Return costs
Return costs are paid by the customer, except for a product that is defective, damaged in transit or not as ordered. If you ship from another country, international shipping costs to France remain your responsibility in the same cases.
In those cases, replacement or refund is free and we pay the return shipping.
Faulty, damaged or incorrect product
Contact us within 7 days of receipt at contact@peptidlab.li.
Give your order number and attach photos of the product, the packaging and the parcel.
If the request is accepted, you receive a replacement or a refund.
Lost parcel
If tracking shows the parcel as lost, or it does not arrive within the stated time, email us with your order number.
We open an investigation with Mondial Relay. An accepted claim can lead to a reshipment or a refund.
Refund times
The refund is issued within 14 days of receiving and checking the return.
For a card payment, the amount usually appears within 3 to 5 working days after the refund is issued, depending on your bank.
If you withdraw from the whole order, the delivery fee you paid is refunded as well. The cost of sending the parcel back stays with you, except for a faulty or incorrect product.
