I bought the creatine because it's German production / bottling. It is recommended by experts of famous athletes. I could already after two days of taking daily 5g x three complete pull-ups make (as a woman), bisber I could not even ten cm pull me, so not nearly pull up to the bar! I feel the huge power boost right now and am fully satisfied! Side effects: THIRST !!! A recommendation for those who begin to take: Never without water bottle out of the house !!! The body requires water without end! Especially at night, I had a dry mouth regularly and had to drink a lot! But this is nothing negative, because it is the effect that creatine causes: It pumps the water during training in the muscle, so you have to always drink plenty of water! Otherwise I can only talk so far of increased bloating that I would still perform as a side effect! Incidentally, I would like to mention that I'm not Auffüllkur at the beginning, as said many times, because the body can only store 5g daily anyway and excretes the rest. So that's unnecessary! Also, the creatine must not be taken exactly in front of the training because the body creatine stores as we have said, and releases only when needed! I can confirm also that I creatine morning engaging because the extreme thirst and also in the evening still can bring more power! What else is there to say? The price. I think that is a very fair price for pure creatine. Everything about it is paid for the brand. Top Product !!!
