Orders, delivery and returns
How do I know if an item is in stock?
Clothing sizes and Muscle Market products from other brands show as out of stock when none are left. Free Muscle-brand products do not show a live stock count. If something you order has run out, we email you, cancel that item and refund everything you paid for it.
How long does UK delivery take and how much does it cost?
UK delivery is free on every order, with no minimum spend. Orders placed before 2pm UK time, Monday to Friday, are dispatched the same working day. Orders placed later, at weekends or on UK public holidays are dispatched the next working day. Delivery usually takes 2 to 3 working days after dispatch. Please allow up to 5 working days. If you need it sooner, choose Faster tracked UK delivery at checkout for £6.00, a priority tracked service that usually arrives 1 to 2 working days after dispatch.
Do you deliver to the EU and other countries, and will I pay customs charges?
Yes. Checkout shows whether we deliver to your address, and the flat delivery rate, before you pay. EU delivery usually takes 3 to 7 working days after dispatch, and the rest of the world 5 to 14. Your country may charge import VAT, customs duties or a clearance fee, which you pay on top of our prices. Please check that you may lawfully import the products before you order.
How do I track my order, and is the packaging discreet?
Every order is tracked. When your parcel is dispatched, we email you a tracking number. If you cannot find the email, check your spam folder, then contact us. We send orders with Royal Mail or Parcelforce, and outside the UK a local carrier may make the final delivery. Every order is sent in plain, discreet packaging.
My order has not arrived. What should I do?
If your order has not arrived within our delivery times, email us with your order number and we will look into it with the carrier. If your parcel is lost in transit, we send a replacement or give you a full refund, whichever you prefer. We deal with the carrier, so you do not need to claim from them yourself.
I received the wrong item or it arrived damaged. What do I do?
Email us with your order number and tell us what is wrong. Photos help us sort it out quickly. We put it right and pay the reasonable cost of returning a faulty, damaged or incorrect item. In the UK you can reject a faulty item within 30 days of delivery for a full refund. These rights also apply to opened products.
How do I return an item?
You can return unopened products in their original condition within 30 days of delivery, and clothing that is unworn with its tags. Email us before you send anything and we reply with our UK returns address. You pay the return postage unless the item is faulty, damaged or incorrect. We refund the price within 14 days of receiving it back.
Can I cancel my order or change the delivery address?
To cancel, email us a clear statement. You do not need our permission. Consumers in the UK, the EU or the EEA can cancel before delivery and within 14 days after receiving the goods. Sealed supplements and research compounds cannot be cancelled once the seal is broken after delivery. If your address is wrong, email us straight away and we will try to correct it or stop the parcel.
What payment methods do you accept?
We accept debit and credit cards. Cash on delivery is available only for deliveries to Romania. If checkout offers you cash on delivery for an address outside Romania, please choose card payment instead.
How do I contact Free Muscle customer service?
Email us at freemuscleuk@gmail.com and include your order number if your question is about an order. We answer emails Monday to Friday, 9:00 to 18:00 UK time, and aim to reply within one working day. For returns, email us first and we send you the UK returns address.
