Return and Refund Policy

At Revion Research Lab, we maintain stringent quality control and safety standards across our entire catalog of research-grade compounds and analytical reference materials. Because our products include temperature-sensitive biological and chemical research compounds such as Revion Retatrutide and Revion Tirzepatide we must enforce strict compliance policies regarding physical returns.

Due to strict laboratory safety standards, cold-chain storage requirements, and the integrity of chemical research materials, all research compounds, liquid formulations, and pre-measured pen delivery devices (including the Revion Retatrutide Pen 40mg) are non-returnable and non-refundable once dispatched.

Once a product leaves our cold-chain storage and delivery facility, we cannot re-verify its chain of custody, storage temperature compliance, or chemical purity. Therefore, returned chemical goods cannot be accepted or re-entered into inventory.

  • Before Dispatch: You may request an order cancellation and receive a full refund if your order has not yet entered the fulfillment or dispatch process. Contact customer support immediately at support@revionresearchlab.co.uk with your order number.

  • After Dispatch: Once a shipping confirmation and tracking code have been generated, the order cannot be canceled or recalled.

We take extreme care in packaging all research materials. If your order arrives damaged, compromised, or containing incorrect items, we will issue a replacement or refund under the following conditions:
