Returns & Refunds Policy

Why returns are limited

Zaesty Peptides supplies research-grade compounds for laboratory use only. These materials are batch-tested, often supplied as lyophilized powder, and sensitive to heat, moisture and handling. Once a vial leaves our facility we cannot confirm how it was stored, so we cannot return it to inventory or safely resell it. This is standard practice for research reagents, and it protects the integrity of every batch we ship.

What we cover

Although we do not accept change-of-mind returns, we stand behind what we ship. The following are always eligible for a replacement or refund once verified:

How to report a problem

1. Do not discard anything. Keep the vial, outer box, packing material and shipping label until your claim is resolved.
2. Take clear photos of the shipping label, the outer packaging, and the affected product, including the batch number on the vial.
3. Email us at [SUPPORT EMAIL] with your name, order number and a short description of the issue.
4. We respond within 2 business days to confirm your claim or ask for anything missing.

Please contact us before sending anything back. Parcels returned without prior authorization cannot be accepted or credited.

Replacements and refunds

For verified claims, you choose between two outcomes where stock allows:

• Free replacement: we ship a replacement at no cost, with tracking.
• Refund: we refund the affected item. Where the problem was our error or carrier damage, we also refund the original shipping charge.

Approved refunds go back to the original payment method within 5 to 10 business days of approval. Your bank or card issuer may take additional time to post the credit. We do not issue refunds to a different card or account than the one used for the order.

If a return of the item is needed for investigation, we will email you written instructions and, where appropriate, a prepaid label. Do not return product unless we ask you to.

Lost or delayed packages

Tracking details are emailed once your order ships. Please allow the full delivery window shown at checkout before reporting a delay.

• If tracking has shown no movement for 5 business days, or the carrier confirms the parcel is lost, contact us and we will open a trace with the carrier.
• Once a parcel is confirmed lost, we will send a replacement or issue a refund, at your choice.
• If tracking shows a parcel as delivered, please check with neighbors, building reception and any safe location first, then contact us within 7 days. We will help you file a carrier claim, but we cannot guarantee a replacement for parcels confirmed delivered to the address on the order.

Cancelling an order

You can cancel for a full refund at any time before your order ships. Email [SUPPORT EMAIL] with your order number as soon as possible. Orders are usually processed within 1 to 2 business days, and once a shipping label is created we cannot guarantee that a cancellation can be accepted.

What is not covered

• Change of mind, ordering the wrong item, or no longer needing the product.
• Opened, used, reconstituted or partially used products without a verified defect.
• Damage or degradation caused after delivery, including improper storage, temperature exposure or handling.
• Claims reported more than 7 calendar days after delivery, or without the required photos and order details.
• Original shipping charges on approved cancellations after shipment, unless required by law or the issue was our error.
• Customs duties, import taxes, and any delays or seizures by customs authorities, which are the responsibility of the recipient.
• Experimental outcomes. Our compounds are supplied for research and we make no representation about results.

Payment disputes

Please contact us before opening a dispute or chargeback with your bank or card issuer. Most issues are resolved faster by email, typically within a few business days. We reserve the right to contest chargebacks that conflict with this policy, using the order confirmation, tracking, delivery confirmation, your acceptance of our terms and your research-use acknowledgment as evidence.

Your legal rights

This policy does not limit any rights you have under the laws of your country or state that cannot be waived by agreement. All products are sold for laboratory research use only and not for human or veterinary consumption. We may update this policy from time to time, and the version in effect on the date of your order applies to that order.
