    I‘ve been a big fan of ON for a long time. However, one would think and hope that the quintessential health powder option would drop the Red 40 and other artificial dyes that have no health benefit and ever more research is saying is bad for you. (Strawberry flavor)

    I really like the flavor of the double rich chocolate, so I decided to order another flavor to test it out. Unfortunately, I was given 2 of the chocolate instead of one chocolate and one cinnamon roll. I would give 2 stars for messing up the order, but at least I know I like the ones that I got.

    Though it tastes great, I still can’t believe this thing came being half filled. I’ve bought other products similar to this one but have always gotten the container filled. I would like to know why was this half filled. Dissatisfied and disappointed.

    Definitely a bit shady, you think you're getting a good deal until you open up the container and realize that it's only about 60% full. Flavor was okay and the scoop itself was all the way at the bottom of the container (I don't know who thought that was a good idea.) not a very sanitary way to get your scoop when you have to drive your entire hand into the container to fish it out. not worth the price or the hassle.

    I decided to try ON Whey Protein because I love their Casein Protein Chocolate Supreme. I have a high level of respect for the ON products but the taste on this Whey Protein is not right. So much so that I could only give it 3 stars. Something about the Extreme Chocolate Milk flavor tastes like "fake" flavoring. I don't need it to taste just like chocolate but I am used to a nice taste from their Casein mix and this is very unpleasant. There is a lingering flavor I can't take no matter if I mix it with water of milk. I cannot recommend this flavor.
    I'm unsure how to go from here since these tubs are an investment for me. I'd hate to be two tubs deep, out money, and unsatisfied with the outcome.

    Love the protein, hate the packaging. Purchased the 10lb bag. Has a zip lock at the top of the bag which is useless because it’s heat sealed so tight you have to cut it off to get the bag open. Ended up transferring the protein to zip lock bags. Would recommend buying the smaller size plastic containers.

    I purchase Optimum Nutrition Whey Protein because I’ve come to trust the brand to provide quality protein powder. I usually stick with chocolate or vanilla, but selected Chocolate Peanut Butter on the listing by accident. Instead of changing it I stuck by it thinking it would be decent, but ugh. Not looking forward to this month, glad I didn’t buy 5lb.

    I do mix it with flavorless collagen, but I don’t think it’s influencing the overall taste by much. It doesn’t with other ON flavors. The flavor just reminds me of a disgusting watermelon pre-workout with these disgusting beads that would pop in your mouth. Idk where the familiarity is coming from but it’s close to repulsive.
