We Stand Behind Every Product

All products offered by Peak Peptides are research compounds intended strictly for in-vitro laboratory research. They are not intended for human or animal use, ingestion, or bodily introduction of any kind. By completing a purchase, you confirm that you have read and agreed to our Terms and Conditions and the Legal Notice included with your shipment.

Given the nature of research compounds and our inability to verify product integrity once a package leaves our facility, Peak Peptides does not accept returns on any shipped orders. This policy exists to preserve product integrity and uphold the standards of the research community.

Before Shipment:

You may cancel your order for a full refund at any time before it has been shipped.

After Shipment:

Once an order has been dispatched, cancellation is no longer available. If you need to cancel, please reach out to us as soon as possible.

To request a cancellation, email support@peakpeptides.shop with your order number.

No Guarantee:

Submitting a request does not guarantee approval. Most requests of this nature are not approved. This provision exists only to allow for flexibility in genuinely exceptional situations and should not be read as an extension of our standard policy. All decisions are final.

Peak Peptides does not provide guidance on reconstitution, dosing, administration, or any application of our products. We operate under the assumption that all customers are qualified researchers with working knowledge of the compounds they are purchasing.

We will not respond to inquiries regarding:

• Preparation, use, or administration of products
• Dosing or concentration guidance
• Expected effects, outcomes, or product comparisons
• Suitability for any specific application

Any communication suggesting use inconsistent with laboratory research will result in a Refusal of Service, and no further assistance will be provided.
