The purpose of the thread is to basically share experiences with protein powders. I have tried quite a few different ones at this point, never delved into anything really cheap, have always tried to stay "middle of the road." My absolute favorite and probably more of a higher end one that I have used is Beverly International UMP, followed closely by Gold Standard Whey. I think UMP is better because it has Casein blended in and overall is just great. Now the courtesy part, is the not so favorites, and that being the ones that have caused, we will say, gastrointestinal distress. Now I know consuming too many BCAA's in a short amount of time can cause this problem but there are two particular proteins I have tried that cause this after one shake, at least for me. That being Muscletech Phase8, this was earlier on when I was more of a protein newb, and didn't realize Muscletech had basically turned into a volume over quality company. The second one that occurred recently and sort of surprised me was Total Protein by Culter Nutrition. It has all sort of fancy certifications but still causes this problem for me. Any others have a similar experience or other brands they care to talk about?
