There are 50 scoops of the CarbMAX formula in every tub. 1 scoop is considered 1 serve. So that's 50 serves per tub.

Absolutely, in fact CarbMAX was formulated specifically with capacity for varying doses in mind.
Depending on your needs,it is expected that CarbMAX could be double or even triple scooped for particularly large persons, depending on the duration and intensity of the given activity. It is partially for this reason that the electrolyte, citrulline, and glycerol doses are kept on the lower end, thus ensuring when multiple servings are required or CarbMAX is used alongside a preworkout, no ingredient is being overdosed.

Yes - however you will also need to include an additional electrolyte source as with your higher sweat rates will also come higher demand. Depending on total duration of the activity, and intensity, use of multiple serves, up to 2.5 scoops per hour would be valuable to contribute a slow releasing carbohydrate source of both glucose and fructose. When seeking particularly high carbohydrate intake in the realm of 90g/hr, other food sources of glucose only should be incorporated due to it's higher saturation capacity than fructose. If you require a lightweight option on race day, CarbMAX can easily be made into a more viscous like gel by mixing with a very low quantity water or glycerol. This is a good solution where water is available at checkpoints and a minimalist carry is desired.

Both Palatinose™ and Cluster Dextrin™ are slow release, low GI carbohydrates. The differences lie in that Cluster Dextrin™ is a larger compound of 60-70 glucose units, with a complex cyclical branching that lends to a pipe like structure that slows rate of breakdown. Palatinose™ is a modified sucrose molecule of one glucose and one fructose, with bonding that is highly resistant to breakdown. They have very similar rates of glucose uptake, both having a Glucose Index score (GI) of 32. The reason Palatinose™ is our preference fuel source is that it also utilizes fructose as an additional fuel source - being more valuable for direct liver glycogen replenishment on a gram for gram basis. Due to it's larger molecular structure, Cluster Dextrin™ does have a lower contribution to osmolality. Hence when creating very low water volume isotonic or hypotonic beverages is a goal (for faster gastric emptying and hydration effeciency), then a combination of the two might have most value.However in the case of CarbMAX the expectation is that water volume is not a restricting component, such that any less than 275ml per scoop is required. Palatinose is isotonic (300±10 % mOsmol/kg) at approximately 9g per 100ml, hence an isotonic or hypotonic beverage is easily achievable.
