Return & Refund Policy

This policy applies to all orders placed on pepteria.com. Products are sold by Research STEM OÜ (reg. 17565752, VAT EE103017220, Tornimäe tn 5, 10145 Tallinn, Estonia) under the Pepteria Laboratories brand.

All products are supplied strictly for laboratory research use only to buyers who have registered and signed the researcher declaration in a professional, scientific or institutional capacity. They are not medicines, dietary supplements or consumer goods.

You may cancel an order free of charge at any time before it has been shipped. Write to us with your order reference (for example 2026-10101).

If you have already transferred the payment, we refund the full amount to the bank account it came from.

Research compounds are temperature- and contamination-sensitive. To protect the integrity of every batch, we cannot accept returns of products once they have left our control, including unopened vials, unless the delivery was damaged, incorrect or defective as described below.

Because buyers purchase in a professional research capacity, the statutory 14-day consumer withdrawal right does not apply. Where mandatory law in your country grants you additional rights, those rights are not affected by this policy.

Please inspect your parcel on arrival. If a vial is broken, the seal is compromised, you received the wrong product or strength, or an item is missing, contact us within 7 days of delivery.

Include your order reference, a description of the problem and clear photos of the parcel, packaging, labels and batch numbers. Do not use or discard the affected product until we reply.

Once confirmed, we will at our choice send a free replacement or refund the affected items, including the original shipping cost. If we ask you to send items back, we provide instructions and cover the return cost.

If you believe a product does not match its documented specifications, contact us with the batch number and any analytical data you have. We will review it against the batch documentation and, if the concern is confirmed, offer a replacement or refund.

If your tracking shows no progress for 10 business days, or the parcel is marked delivered but has not arrived, contact us. We will open an investigation with the carrier and, if the parcel is confirmed lost, reship or refund the order.

Parcels refused, unclaimed or returned because of an incorrect delivery address, or held or destroyed by customs because of import rules in the destination country, are not eligible for refund.

As stated in the researcher declaration, we may refuse or cancel an order if identity or compliance verification is unsuccessful. In that case any payment received is refunded in full to the originating bank account.

Refunds are paid by bank transfer to the account the payment came from, in the original currency (EUR), normally within 14 days of our approval. Bank charges applied by your own bank are not covered.

If an affiliate discount code was used, the refund equals the amount actually paid.
