The short version

Research peptides cannot be restocked once they leave our facility, so every sale is final after dispatch. The exceptions are set out in section 3.

  • Full refund if cancelled before dispatch
  • Transit damage reported within 48 hours
  • Returns only with written approval

Before dispatch

Cancel before your order enters fulfillment for a full refund.

Transit damage

Send clear photos within 48 hours of delivery for a review.

Lost parcels

Reviewed once the carrier’s investigation declares the parcel lost.

COA guarantee

Each lot’s HPLC-MS certificate confirms its integrity at dispatch.

1. Nature of our products

Every TLC Renew product is supplied strictly for in vitro laboratory and scientific research, and never for human or veterinary consumption.

Research-grade peptides need temperature-controlled handling, sterile reconstitution and controlled storage. Once an order leaves our facility we cannot confirm how it was kept, so it cannot be returned to inventory or redistributed. For that reason, every sale is final once an order has been dispatched, except in the cases set out in section 3.

2. Order cancellations

You can cancel an order before dispatch by emailing research@tlcrenew.com. If it has not yet entered fulfillment, we refund it in full.

In-stock orders placed before 11:00 AM are dispatched the same day, so please write as soon as possible. Once an order has been dispatched it cannot be cancelled for any reason, including refused delivery, failure to collect, or return to sender.

3. When a refund applies

We consider a refund or replacement only in these cases:

  • Confirmed manufacturing defect. Supported by documentation and assessed at our discretion.
  • Transit damage. Supported by clear photos sent within 48 hours of delivery.
  • Parcel declared lost by the carrier. Reviewed once the carrier’s investigation is complete, usually 10 to 15 business days after it opens.

No other circumstances qualify for a refund.

4. What is not refundable

We do not issue refunds for:

  • A change of mind or the wrong product chosen
  • Opened, used or tampered products
  • Improper reconstitution, handling or storage after delivery
  • Research outcomes, experimental results or views on product performance
  • Delivery delays while a parcel is still in transit
  • An incorrect shipping address given at checkout
  • Refused delivery or failure to collect
  • Delays or losses caused by the carrier or by events outside our control

5. Returns

We accept a return only when we have authorized it in writing in advance. Unauthorized returns are refused and may be disposed of without a refund.

An authorized return must be unopened, unused and in its original sealed packaging. Every returned item is inspected before any refund or replacement is approved.

6. Reconstitution and handling

Peptides are sensitive research compounds. They need proper handling, sterile reconstitution technique and the right storage conditions. We are not responsible for degradation or loss caused by improper reconstitution, the wrong storage temperature, contamination during handling, or any other mishandling after delivery.

Every lot is independently HPLC-MS tested, and its lot-matched Certificate of Analysis confirms identity and purity at the time of dispatch. That certificate is our quality guarantee.

7. Chargebacks

Please contact us at research@tlcrenew.com before opening any chargeback or payment dispute. Most problems are resolved quickly by email.

We contest every chargeback that rests on a misunderstanding of research-only status, an attempt to cancel after dispatch, a delivery delay, a refused or uncollected parcel, or a disagreement with this policy rather than a confirmed defect.

We keep full records for every order, including the order confirmation, the research-use acknowledgment accepted at checkout, shipping confirmation, tracking history and policy acceptance.

8. Abuse and fraud prevention

Repeated refund requests or chargeback abuse may lead to permanent account suspension and refusal of future orders. We may report abusive activity to payment processors and fraud prevention networks.

9. Refund processing

Approved refunds are returned to the original payment method within 3 to 5 business days. Your bank or card provider may take longer to show the funds in your account.

Our products are supplied for professional laboratory research, and they cannot be returned for safety, sterility and contamination-control reasons. This policy is written on that basis. Nothing in it limits any right you have under federal or state law that cannot be waived.

11. Policy acceptance

By placing an order, you confirm that you understand the research-only status of every product, accept the conditions in this policy, and agree not to seek a refund or chargeback outside the cases described above. This policy applies together with our Terms of Service and Research Use Only Policy.

12. Contact
