The only ON flavor that made it on their clean list was vanilla ice cream, out of the ones they tested. The study specifically called out chocolate flavors for testing higher for contaminants. If you go to the bottom and click on the protein powders used in the study, you'll see that no chocolate flavors got their "clean" label. Many of the powders with the clean label are either vanilla or unflavored. I saw one mango flavor that made the list.

I’m using ON, but Strawberry. Just a personal preference, Strawberry over Chocolate.

I thought it’s quite ok. Personally, I don’t feel it taste artificial. I mix my protein powder with Meiji milk.

I use the strawberry ON one and it's great. Tastes like Angel Delight!

ON strawberry, some of ON flavours are very overpowering and can leave you nauseous (chocolate, cookies and cream).

Our Costco almost always has the Kirkland, ON, and Orgain plant powders for a great deal. Look for the 'Aussie Bites' in the snack section, the ingredients / protein is pretty crazy for the small bites.

Hi. I have tried GNC and ON and didn't like both. How is MB in terms of quality ? Heard the taste is good.

Doesn't mix as well as ON, messes with my stomach, and doesn't taste as well either. I bought a bag of the Kirkland powder to try, boy it was tough to get through. The wife and kids didn't really like and were more than happy to go back to ON.
