PEScience Select Protein Powder is a 15-serving whey-and-casein protein blend designed to support daily protein intake, with 24g of protein per serving and milk protein isolate as its first ingredient.
For people building a protein shake into a fitness routine, choosing a powder can mean balancing protein content, flavor, and the ingredients in the blend. PEScience Select is made for varied fitness goals and for everyday use when you want a protein-focused option with a bakery-inspired cookie flavor. Its protein blend, mix-in choices, and 15-serving format make the product details easy to compare against your routine.
PEScience Select combines whey and casein, with milk protein isolate listed first in the blend. The formula is designed to support muscle recovery and provide sustained muscle support through the day, rather than relying on 100% whey alone. Casein also contributes to the product’s intended longer-lasting fullness, which can be useful when choosing a protein drink as part of a high-protein, low-calorie eating plan.
Island Cookie combines toasted coconut, warm oats, and buttery pecan flavor notes. PEScience developed the powder for a smooth texture and digestibility, and its award-winning flavor range is made to mix smoothly with either water or milk. Choose either liquid to prepare the shake; the product details do not give a mixing ratio, so this description does not assume one.
Independent laboratories third-party test Select Protein for purity and quality. The formula uses no proprietary blends, making its ingredients transparent rather than grouped under a proprietary blend name. The product is also presented as suitable for several dietary preferences, including Kosher, Halal, vegetarian, keto, low-carb, low-calorie, and gluten-free needs.
PEScience Select is suited to shoppers seeking a flavored protein powder for fitness routines, with a whey-and-casein blend, flexible mixing choices, and a flavor profile built around coconut, oats, and pecan. It is a protein powder rather than a complete meal specification, so its stated meal-replacement role is as a low-calorie, high-protein option. The 15-serving Island Cookie powder combines 24g of protein per serving with a blend led by milk protein isolate.
Select Protein Blend (Milk Protein Isolate [comprised of casein protein and whey protein], Whey Protein Concentrate 80%, Leucine Peptides), Natural and Artificial Flavors, Salt, Guar Gum, Sucralose, Acesulfame Potassium
