Returns & Refunds

Last updated: May 25, 2026

Due to the nature of research peptides and the strict handling requirements they demand, Kinetic Compounds does not accept returns. Refunds are issued only in limited circumstances outlined below, and all refund requests are evaluated on a case-by-case basis.
No Returns Policy Once a research peptide leaves our facility, we cannot verify how it has been stored, handled, or transported by third parties. To protect the integrity of our supply chain and the safety of all customers, all sales are final. We do not accept returned product for resale, refund, or exchange.

When Refunds Are Issued

We will consider refunds, replacements, or store credit in the following situations:

  • Damaged on arrival: The vial arrives broken, cracked, or compromised due to shipping damage.
  • Visual defect upon reconstitution: The peptide, once reconstituted with bacteriostatic water within the recommended time window, does not appear as expected — for example, persistent cloudiness, visible particulates, or unusual coloration that indicates a quality issue.
  • Wrong product shipped: You received a product different from what you ordered (incorrect peptide, incorrect dose, or incorrect quantity).
  • Missing items: Your shipment is missing items listed on the packing slip.

How to Request a Refund

All refund requests must be submitted with photographic evidence and supporting details. Without documentation, we cannot process a request.

Reporting Damaged Shipments

Damaged shipments must be reported within 48 hours of delivery.

  • Photograph the damaged vial(s) in their original packaging before disposing of anything
  • Photograph the outer shipping box, particularly any visible damage
  • Retain all packaging materials until we confirm the resolution
  • Email research@kineticcompounds.com with photos, your order number, and a brief description

Reporting Reconstitution Defects

If a peptide does not appear as expected after reconstitution, you must submit a request within 12 hours of reconstitution.

  • Photograph the reconstituted vial clearly, showing the visible defect (cloudiness, particulates, discoloration, etc.)
  • Include details on the reconstitution process: type of bacteriostatic water used, volume added, storage conditions before reconstitution
  • Provide your order number and the batch number visible on the vial label
  • Email the documentation to research@kineticcompounds.com
Why The 12-Hour Window? Reconstituted peptides should be evaluated immediately. Improper storage of a reconstituted peptide can introduce defects that are unrelated to product quality. The 12-hour window ensures we're evaluating the product as delivered, not the result of subsequent handling.

What Is Not Covered

The following situations are not eligible for refunds, replacements, or store credit:

  • Lost or stolen packages: Once a package is marked delivered by the carrier, we are no longer responsible for it. We strongly recommend shipping to secure addresses and tracking deliveries closely.
  • Carrier delays: Shipping delays caused by carriers, weather, or customs processing are outside our control and do not qualify for refund.
  • Buyer's remorse: Changed your mind, ordered the wrong product, or no longer need the peptide. All sales are final.
  • Improper storage after delivery: Damage caused by improper storage (extreme temperatures, repeated freeze-thaw, exposure to light) after the package was delivered.
  • Improper reconstitution: Defects caused by using the wrong solvent, incorrect volume, contamination during reconstitution, or storing reconstituted product improperly.
  • Reports submitted outside the time windows: Damage reports submitted more than 48 hours after delivery, or reconstitution issues reported more than 12 hours after reconstitution.
  • Products that have been used: Partially used, opened, or sampled vials are not eligible for any form of refund.

Case-by-Case Evaluation

Every refund request is evaluated individually by our research support team. We weigh the available evidence, the timing of the report, the specifics of the issue, and the customer's order history.

Approved refunds are processed back to the original payment method within 5–7 business days of approval. In some cases, we may offer store credit or a replacement shipment as an alternative to a cash refund — the choice is yours.

Order Cancellations

If you need to cancel an order, contact us immediately. We can cancel orders that have not yet been processed for shipment. Once a tracking number has been generated, the order cannot be cancelled — at that point, it must be handled under the normal damage or defect reporting process if there is an issue with what was shipped.

Need to Report an Issue?

Our research support team responds within 12 hours during business days. Include your order number, photos, and a description of the issue.
