Unfortunately, I have been doing the occasional negative reviews as for me less relevant outliers considered (success stories finally to read much better than critical voices ;-)), but this is where you should start and be very careful. I really wanted to make a creatine treatment and how many "experts" recommend for a week a "loading phase" perform, but it remained at a one-off cautions. An hour after the first dose (5 g) I got severe diarrhea, which lasted several hours. In the evenings, also came a flu infection symptoms to - where I can have my course suffered otherwise. I can however say that the creatine intake has done my body not good or even totally charged him safely say.
I can pull for me as a conclusion that I will continue to do in the future only on a balanced diet and protein shakes and will refrain from such experiments. Even the people who were there tolerated better ask yourself if necessary if it slightly faster muscle growth is worth burdening his body so (yes I know it's been no scientifically proven side effects are - apart from kidney damage if you drink while taking too little - but in my case it is sufficient simply to your body to hear ...).
