22g whey isolate in dessert-style Funky Flavours
Applied Nutrition ISO-XP is the brand's whey protein isolate built for trainees who want maximum protein per calorie with minimal sugar and lactose. Each 25g serving delivers 22g of pure whey isolate at just 92 calories, with 0.4g of fat, 0.04g of carbohydrates and 0.02g of sugars. The tub provides 40 servings across the Funky Flavours range.
The protein source is 100% whey protein isolate processed through cross-flow microfiltration. Isolate is filtered further than whey concentrate to remove most of the fat, lactose and carbohydrate fractions, which is why the macro profile reads cleaner than a daily-driver concentrate. The result is 88% protein by weight - one of the higher purities in the catalogue. Low lactose content makes it tolerable for trainees who notice digestive issues with concentrate-based shakes.
What separates ISO-XP from a standard whey concentrate is the macro stripping. Cutting carbs to 0.04g and sugars to 0.02g per serving means the protein hit fits cleanly into a calorie-controlled cut without spending the protein budget on sugar. The Funky Flavours range targets dessert-tier flavour profiles (Choco Hazelnut, Bueno White Choc) without the carb overhead that flavoured concentrates carry.
ISO-XP suits competitive lifters in a cut phase, trainees with mild lactose sensitivity who can't run a standard concentrate, and anyone who tracks macros tightly enough that the 0.04g carb count matters. It is not the right pick if budget is the priority - isolate carries a price premium over concentrate for the additional processing. Contains milk.
