HI I must warn you that my English is very bad... so forgive me,please!Is there any side effects of CREATINE. I heard something about kidney problems!? Any food & drinks that I should not take while on CREATINE? I also heard something about caffeine(that it should not be taken while on creatine?- I guess it has something to do with effectiveness)?
How creatine exactly works?
