Highest concentration of protein per serving of any protein.
Great value! Tastes fine, texture is like any other casein which is naturally a little gritty and gelatinous all in one. Packaging was higher end, usually a good sign in the supplement world. I had the vanilla, at 30 bucks for 5 pounds is a steal!
Gritty texture when drinking, slightly bitter taste. Got the vanilla flavor. Great price. I recommend mixing it with some other flavored beverage like milk to better mask the flavor.

Ultimate Nutrition. PROSTAR CASEIN: Prostar Casein protein powder is the ideal combination of moderate-tempo hydrolyzed casein (2–4 hours digestion time) and gradual-release micellar casein (4–7 hours digestion time) to steadily shuttle amino acids to fatigued muscles over long stretches of inactivity MICRO-FILTERED: Prostar Whey utilizes a proprietary micro and ultra-filtration process to remove the larger particles and may remove some viruses to ensure the highest quality whey protein powder. Micro-filtered whey protein isolates offer fast-release amino acids that are rapidly absorbed. FOR ATHLETES AND BEGINNERS: Our protein powder fits the needs of men and women who are seasoned athletes or beginners embarking on their fitness journey and improving athletic performance and increasing strength. Regularly consuming whey protein increases muscle strength and athletic performance. DIFFERENT TASTE: Protein powder comes in 14 delicious flavors including, unflavored.
