Availability & prices


Our entire stock is online. That means that we have no products in a hidden corner. Every day we walk through the stock to keep this up-to-date and yet it can happen that we miss out. We will always contact us and offer an alternative (or possibly afterwards as soon as it is inside).

The stock is not huge and we do that consciously. How so? By having a smaller stock, we ensure that our stock is always equipped with the most recent and a long shelf life date. This way we ensure a rapid change of our products.

Are you planning to place a large order, such as for your entire team that goes on a training internship or participates in a nice multi -day tour such as Giro di Kika, the Pyrene Challenge or the Tour for Life? Let us know. We are happy to offer you a special deal.

By having our own stock, we can therefore quickly respond to your wishes. Ordered today (on working days) is often delivered the next day.

Did you know that you can also see the minimum expiration date of the products. Is there nothing to it? Then the product can be kept for at least 4 months. A THT date does not say much in sports nutrition, because the effect, taste and composition of the product only changes very slowly. Often you can use it for months (and sometimes years) after the indicated THT date.


Our prices are very competitive and often something cheaper than with the competitors. The basic price that we use is the Sales Advice Prize as advised by the supplier.

In addition to the already competitive prices, you can gain even more advantage by looking at our scale discounts or special packages. With this you often save between 3% and 5% on the product. The scale discounts can be found on the product page.


The SIS Beta Fuel Chew Bar is a new energy bar in the range of SIS Sports nutrition. Thanks to the soft texture, the Chew bars are very easy to eat before and during the effort. You receive no less than 46 grams of carbohydrates per strip of 60 grams in order to improve optimum performance. This bar is particularly suitable for long -term efforts. The Beta Fuel Bar consists of 6 soft energy chews and is easily digestible. The Beta Fuel Chew Bar available in the flavors Orange and Lemon.

As an endurance athlete who makes an effort for more than two hours, you have to get between 80 and 120 grams of carbohydrates per hour. Our science in Sport Beta Fuel Dual Source Energy Gel Chews deliver 46g fast carbohydrates in a handy and tasty chewing tablet, which are optimized with a new ratio that increases the power yield and makes the carbohydrate utilization more efficient without stomach and intestinal complaints.

New 1: 0.8 ratio replaces 2: 1 ratio

The bar is therefore equipped with a 1: 0.8 ratio from maltodextrin to fructose. This new ratio from maltodextrin to fructose increases the percentage of carbohydrates taken that is oxidized from 62% to 74%, compared to the original ratio of 2: 1. This formula has therefore been extensively tested and also ensures the reduction of nausea and stomachity.
