Well in any case I might consider to keep taking creating once to twice a week...
It wont really do anything for you unless you do proper creatine cycles. Usually it's 2 table spoons twice a day with grape juice the first week, 1 table spoon once a day for 2 weeks, then 2 table spoons twice a day for the final week with 2 weeks off after this cycle.
Rinse and Repeat.
I concur, I had REALLY negative effects because I didnt keep properly hydrated the year I was on it. I frequently woke up with the most painful calf cramps in all of existance. And during football games my calves would completely lock up and I'd fall over. Which I saw as a negative. I would recommend Phosphegen, I gained more mass on it with less crampage.
