30-Day Satisfaction Guarantee

We stand behind every product we sell. If you are not satisfied with the first purchase of a product, email us within 30 days of delivery and we refund the product price: no return shipment, no forms, no interrogation. The conditions are below and in our Refund Policy.

How it works

  1. Contact us at freemuscleuk@gmail.com within 30 days of delivery, with your order number.
  2. Tell us (in one sentence, honestly) why you were not satisfied. It helps us improve.
  3. We issue a full refund of the product price to your original payment method, typically within 3 to 5 working days. You do not need to send anything back.

Fair-use terms

  • The guarantee applies to the first purchase of each product, per customer.
  • It covers the product price; original shipping costs are refunded only if the order arrived damaged or incorrect.
  • Bundles are covered as one product.
  • We reserve the right to refuse the guarantee in cases of clear abuse (e.g. repeated claims across orders).

Every batch of a Free Muscle-brand product is independently assayed by Janoshik Analytical, with the Certificate of Analysis for a batch available on request. For other brands, a certificate is available only where the manufacturer supplies one for the batch we hold. See our How We Test page.
