I bought this during nutraplanet sale and tried both flavors this week.
1- no joke about clumps. It mixes with ease. I keep a funnel in my car since I tend to mix on the run in a bottle of spring water a lot. (such as deer park) With other protein, it usually clumps somewhere. Bottom of bottle, top of bottle near the mouth or floaters in between. With about 10 seconds of vigorous shaking, it mixes smoothly with absolutely no clumps.
2- The powder is not as fluffy as most protein and slides down smoothly into the bottle in a small funnel. It usually stops on the way down with most protein and I always have to find something to jam it down with. (Pen, straw, tire gauge,.....)
3- I mix 2 scoops with about 12 oz of water and the taste is unreal. It is not as thick as most protein and not overly sweet. The vanilla tastes like a vanilla shake. Best vanilla flavor I have tried bar none. Being a chocolate fan, I was anxious to try the chocolate flavor. The whiff of scent as I unsealed the bottle gave me a preview of amazing things to come. Kind of like hot chocolate mix like the solution said. It tastes like chocolate milk. An awesome chocolate milk. Best whey protein flavor I have ever tasted.
4- No whey breath or aftertaste at all.
I am an now a huge fan of Pronom 23. I can't imagine using anything else. I rushed to Nutraplanet site to get 4 more tubs - 2 vanilla and 2 chocolate. Amazing job with this protein powder Controlled Labs !!!
