PER4M has built a massive reputation as the "Kings of Flavour" in the UK supplement scene, mostly known for their incredibly thick, milkshake-like standard whey blend. Isolate Zero is their premium, ultra-filtered option designed for those who want maximum protein purity with zero sugar, virtually no fat, and zero lactose. For a flavor as typically heavy as Chocolate Peanut Butter, delivering it in a stripped-back isolate formula is a tough balancing act. The Balance: The chocolate takes the lead—it's a clean, smooth milk chocolate base rather than a bitter dark cocoa. The peanut butter follows immediately on the back end, providing a distinct salty-sweet, nutty richness that rounds out the flavor. Sweetness: It is sweetened with sucralose. It manages to taste quite indulgent without leaving that sharp, metallic artificial aftertaste that ruins many other isolate powders. The Verdict: It satisfies a sweet tooth perfectly without feeling heavy on the stomach, making it an excellent post-workout treat or a sweet fix during the day.
