Supbox is a box full of supplements to explore. Protein snacks, drinks, pre-workouts and samples from brands across the fitness world. Open it, try everything, and discover your new favourites.

What’s inside a Supbox?

Each box is packed with a mix of protein snacks, drinks, pre-workouts and whey samples. You’ll get anything from 12 to 20 items to try, depending on which box you choose. The description of the box will tell you how much is in each.

Are the products full-size or samples?

Our boxes are filled with single use items, such as bars, cookies, sample sachets, & drinks etc. We do not sell full sized supplement tubs. It’s all about trying new things without buying a full tub.

Are your products in date?

All Supbox products are carefully checked and tracked to ensure they are within their best before dates. We work closely with our suppliers and monitor stock to make sure everything included in your box is fresh and ready to enjoy.

Do you ever include products past their best before date?

In some cases, we may include an additional product that is past its best before date clearly labelled as an Expired Freebie. These are never part of the paid contents of your box and are included purely as a bonus. Best before dates relate to quality, not safety, and these items are still safe to consume.
