Vanilla Ice-Cream is delicious

Review by Jackie on Jul. 6, 2022
Have been taking this post workout for a couple of weeks or as I snack if I need extra protein. By far the best I have tried. Will definitely be repurchasing.

Great Flavor

Review by Jeff on Jul. 5, 2022
I have tried many protein powders. This one by far for me is the best tasting. The banana cream is so good. I mix it the night before for my lunch at work. It does not thicken up like others have on me and are just nasty. Mixes well for me in a shaker cup, using a spoon and cup does not mix so well. Does not leave my stomach upset. Best hands down for me. This flavor anyway.

BPA free?

Whey protein BPA free?

Is that whey protein BPA free?

Classic, because it's the best

Review by Jenn B on Jul. 2, 2022
I used to buy chocolate protein powder from Idealfit but they've been having supplier problems so I went elsewhere to search for another amazing chocolate protein powder. I tried over 10 powders and multiple chocolate flavors from other companies and they were all awful. Then I decided to try Optimum Nutrition's milk chocolate and I am in LOVE! I don't know why I didn't come here first, silly mistake. I won't even consider another protein powder company after this. Excellent, thank you!

Tasty and pure
