PEScience Select Protein RTD is a ready-to-drink protein shake that tastes like dessert but reads like a macro-friendly meal: 25g protein, 130 calories, 4g carbs and 0g sugar per bottle. Grab one, shake, go — no powder, no scooping, no blender. It carries PEScience's flagship Select Protein flavour quality into a smooth, creamy pre-mixed bottle, built on a whey + casein (milk protein) blend for fast- and slow-digesting protein. Available as a single bottle or a money-saving 4-pack, in Chocolate Truffle and Vanilla Cupcake.
About PEScience
PEScience (Physique Enhancing Science) is a US sports-nutrition brand best known for its flagship Select Protein and its signature whey-and-casein blend, which earned a cult following for genuinely dessert-like flavours and clean, no-nonsense formulas. PEScience third-party tests both its raw materials and finished products (note: it is not Informed Choice / Informed Sport certified).
Why we carry it
We already stock PEScience Select Protein powder because the flavour quality is some of the best in the category. The Select RTD puts that same flavour into a grab-and-go bottle with 25g protein and 0g sugar — a rare combination among ready-to-drink shakes — for customers who want the protein hit without mixing. Diana taste-tested it before it earned a spot on the shelf.
