Salted Caramel strikes the perfect balance between sweet and savoury, blending buttery caramel flavour with a subtle hint of sea salt for a shake that’s as satisfying as it is indulgent. It’s smooth, bold, and brings dessert-like flavour to your daily protein—without compromising your nutrition.
Sourced from EU grass-fed dairy, each scoop of Isolate Zero contains only the highest quality whey protein isolate, rich in peptide fractions like Lactoferrin, Glycomacropeptides, and essential BCAAs. You get 26g of highly bioavailable protein in every serving to fuel recovery and support lean muscle development.
As the Kings of Flavour, PER4M is dedicated to creating shakes that taste every bit as good as they perform. Salted Caramel is a perfect example—deep, rich flavour in a clean, high-quality protein you’ll actually enjoy drinking.
