Hi everyone At the moment I have tried 2 different glutamine brands, 1 of them showing positive results and the other brand giving side effects resulting in a lack of positive results. I have done this test twice now with same results. Pretty clear I will never ever buy the glutamine brand giving side effects. Question? My question is now, can any of you recommend a protein powder for someone that is sensitive and that is free of undeclared ingredients, artificial colors or dyes, gluten etc etc. Not sure if I should argument for brand that is used by the pros cause it's the best but rather a brand that is pure and of high quailty. By the way does all protein powders contain some sort of milk protein or are there brands based on on other sorts ? You know this might not work but I have to give it a shot. Plus the market is flooded with so many protein powder brands I rather start here and ask before buying another brand making me worse. Thanks for your time, hugs!
