“I decided to try a protein supplement as I was simply not able to get the protein I needed from regular food. I purchased this from Costco a month ago and wow my body is already responding incredibly. I take 1 scoop every morning with breakfast, 1 before bed and the days I lift 1 scoop after my workouts as well (full body workout 3x per week). Not tired or sore at all the next day and I feel like I could lift every day. Made huge gains in size and strength after just 1 month with not much body fat increase at all. Two thumbs up!”

“We drink shakes or smoothies twice a day so I'm pretty picky about what we buy. This protein powder has a great taste and creamy texture that mixes well with fruit or yogurt. I like both the chocolate and vanilla. This is the one that is currently being carried at Costco, which makes it a good buy as well. I would definitely recommend this protein powder!”

“This is great whey protein - tastes great in skim milk and even water and no chalky taste either. Great value for 6 lbs of protein! Will last me a while!!”
- KM B. (Amazon.com user review)

“I would definitely recommend for anyone trying to build muscle it has helped me very much and has helped with weight gain.”
