Refund policy

Peptido BioGenetic supplies lyophilized peptides: a biological material that is sensitive to temperature, light and humidity. To protect the integrity of every vial and the safety of all our customers, we do not accept returns or exchanges of products that have already been delivered. If your order arrives with an issue, we will replace it at no cost.

1. Why we do not accept returns

Our peptides are stored and shipped under controlled conditions, and every vial is delivered sealed and tamper-evident. Once the order leaves our warehouse we cannot verify how it has been stored, and a returned vial could not be resold or used with any guarantee. For reasons of hygiene, health protection and product preservation, returns of delivered items are not accepted.

2. Right of withdrawal

Article 103 of the consolidated text of the General Law for the Defense of Consumers and Users (Royal Legislative Decree 1/2007, of 16 November) excludes the right of withdrawal for:

Letter d): the supply of goods that are liable to deteriorate or expire rapidly.
Letter e): the supply of sealed goods that are not suitable for return due to health protection or hygiene reasons and that have been unsealed after delivery.

By their nature, our products fall under these exceptions, which are also set out in Article 16 of Directive 2011/83/EU. We inform you of this before purchase, as required by Article 97.1.n) of the same law.

3. Confirmed orders

We prepare and ship every order quickly so as not to break the storage chain. For this reason, once confirmed, an order cannot be modified or canceled. Please carefully review the products, quantities and delivery address before completing your purchase.

4. If your order arrives with an issue

If you receive the wrong product, a broken or damaged vial, a tampered seal, or an item is missing, we will send you the correct product at no cost:

Write to us at info@peptidobiogenetic.com within 48 hours of delivery, stating your order number.
Attach photos or a video of the package, the seal and the vials as they arrived: we need them to process the claim with the carrier.
Do not open, reconstitute or use the affected product, and keep it until we reply.

We review each case within a maximum of 48 business hours. You do not need to send us the damaged item unless we expressly ask you to.

5. Shipping

If the carrier loses your order or delivers it damaged, we open a claim with the carrier and send you the products again. Delivery times are estimates. If an order is returned to our warehouse because the address provided was incorrect, nobody collected it or it was refused, we can reship it once the new shipping cost has been paid; the returned product is not put back on sale.

6. What this policy does not cover

Products stored, handled or reconstituted in a way other than indicated on their product page.
Opened, reconstituted or used vials.
Expectations about the outcome of a research project. Our products are sold exclusively for research and laboratory use; they are not for human or veterinary consumption.

7. Your warranty rights

This policy does not limit the rights granted to you by law as a consumer. If a product does not conform to the contract, the legal guarantee under Articles 114 et seq. of the same consolidated text will apply. Since a vial cannot be repaired, the remedy will be its replacement with a conforming product; only if replacement is not possible will the other remedies provided by law apply.

8. Before filing a claim with your bank

If you have any problem with an order, write to us first: we resolve issues within 48 business hours, much sooner than any bank claim. We keep the confirmation of every order and the tracking of its delivery.
