This case is made to hold a full weeks worth of your powdered supplements in one easy place. While there are only four of each bottle, they typically are large enough to handle most mainstream powders. Two of each small bottle will hold up to 3 scoops of pre and post-workout. The bottles are easily mark-able with a permanent marker. The larger protein bottles have a 100ml line built in, which corresponds to a 35 gram scoop. If filled completely all four hold the additional scoop above that line. This way in the smallest package possible we can provide room for a full 5 day week of your supplements . While built around a pre-post-protein regimen, this case can be utilized in many ways. BCAAs and even pill form supplements all fit nicely in one easy to manage case. The included fold-able, BPA-free, food grade funnel makes for a no-mess convenient way to fill at home. After filling if the funnel is removed it creates a perfect spot for energy gels or pre-packed vitamins.
