This product is awesome. I tried Naked Mass but it just wasn't giving me the results I wanted. I'm a hard gainer and Optimal Nutrition Pro Gainer provides me with the mix of calories and protein I need. Highly recommend.

I have never had a better tasting, better mixing protein that has so much protein in just one scoop! It only takes up 1/3 of my shaker bottle, leaving plenty of room to add extras! All the other proteins fill the shaker up so much there’s not even room to shake it. I will always buy this!
