1. Change-of-Mind Returns

RS Bio Labs supplies lyophilised research peptides that require controlled cold-chain handling at all times. For that reason we cannot accept change-of-mind returns once a correctly-supplied product has left our facility, because we cannot:

• Verify that the cold-chain has been maintained throughout transit or at the customer's premises.
• Confirm the product has not been partially used, tampered with, or exposed to conditions that compromise its integrity.
• Safely redistribute a returned peptide product without posing risk to other customers.

This applies to correctly-supplied products only. It does not affect your right to return an item that is damaged, faulty, or not as described — those are always accepted (see sections 3 and 5).

2. What Is Not Accepted

• Returns of a correctly-supplied product due to a change of mind or an ordering error.
• Returns due to a misunderstanding of the product's intended research use.
• Returns of opened vials where the product was supplied correctly and as described.
• Returns citing failure to review product listings or this Returns Policy prior to purchase.

3. Faulty or Not-as-Described Items — Returns Accepted

We stand fully behind the quality and purity of every product. If you receive an item that is faulty, does not meet our stated purity, or is not as described (for example the wrong compound, wrong strength, or a product that differs from its listing), we will accept a return and provide a replacement or a full refund.

To raise it, please:

• Contact us within 48 hours of receiving the order.
• Provide your order reference, a full description of the issue, and photographic evidence where applicable.
• Retain the product and its packaging — we may ask you to return it (at our cost) or provide it for independent testing.

Once we've confirmed the issue we'll arrange the return and issue your replacement or refund — your choice. Verified faulty or not-as-described returns are always at our cost to you.

4. Lost or Undelivered Orders

If your order has not arrived within the expected delivery window, contact us by email within 7 days of the expected delivery date. We will raise an investigation with the courier. If the shipment is confirmed lost, we will dispatch a replacement at no charge.

RS Bio Labs cannot be held responsible for non-delivery due to an incorrect address provided at checkout. Please verify your delivery details before placing your order.

5. Damaged in Transit — Returns Accepted

If your order arrives visibly damaged — for example a broken vial or compromised packaging — photograph the damage immediately upon receipt and contact us within 24 hours. We will accept the return and arrange a replacement or full refund at no cost to you. Do not use any product from a damaged shipment.

6. Cancellations

Orders may only be cancelled before dispatch. Once processed and dispatched from our facility, an order cannot be cancelled and this policy applies in full. To request a pre-dispatch cancellation, contact us immediately via.

7. Statutory Rights

Research peptides supplied by RS Bio Labs are sold as research compounds for laboratory use only and are not sold as consumer goods for personal use. As such, standard consumer return rights under the Consumer Rights Act 2015 and Consumer Contracts Regulations 2013 may not apply. By placing an order, you confirm you are purchasing as a researcher or institution, not as a consumer for personal use.

8. Our Quality Commitment

Every product we supply is third-party tested to ≥99% purity. We take quality seriously and stand behind every batch. If something is genuinely wrong with a product — damaged, faulty or not as described — we want to know, and we will put it right with a replacement or refund through the process above.
