22g pure whey isolate per 25g scoop, 72 servings
Applied Nutrition ISO-XP Whey Isolate 1.8kg is the value-pack format of the brand's whey isolate, built for trainees who run isolate as a daily-driver protein and want a lower cost per serving than the 1kg format. Each 25g serving delivers 22g of whey protein isolate at just 92 calories, with 0.4g of fat, 0.04g of carbohydrates and 0.02g of sugars. The 1.8kg tub provides 72 servings.
The protein source is 100% whey protein isolate processed via cross-flow microfiltration to 88% protein by weight. Isolate is filtered further than concentrate to remove most of the fat, lactose and carbohydrate fractions - the reason the macro profile reads cleaner than a daily-driver WPC. The low lactose content suits trainees who experience bloating from concentrate-based shakes. Each serving contributes a meaningful share of the EFSA-authorised protein claim for the growth and maintenance of muscle mass.
What separates the 1.8kg format from the 1kg is purely the cost-per-serving math. At 72 servings versus 40, the per-shake cost drops noticeably for trainees who run two or three isolate shakes a day across a cut or maintenance phase. Same panel, same Funky Flavours range, lower running cost.
ISO-XP 1.8kg suits competitive lifters running isolate daily through cut phases, dedicated trainees who go through protein quickly, and anyone who has tested the 1kg and wants to commit to the format at lower per-serving cost. It is not the right pick for occasional users - the 1kg suits intermittent demand better. Contains milk.
