Samples is a category in which you will find samples of popular products such as protein powders, nut butters, BCAAs, creatine or greens mix. The samples are used primarily to avoid situations when you buy a large package of a product that will not suit you. For example, you can easily order several protein samples and then purchase the one you like the most in a larger and more convenient package.
Moreover, many people also like the samples for their practical use. This way you can always have a serving of your favourite supplement at hand. If you want to indulge in a good dose of protein after training, there is nothing easier than having a protein sample in a sports bag. It's also great to always have a sample of nut butter to satisfy hunger and sweet tooth whenever needed.
