The avg 16 year old isn't as developed physiologically. If you had said someone in their mid twenties, then I would agree.
I see your point and it's fun to take supplements. I don't really take many supplements that have to do with lifting other than protein & WMS, and occasionally creatine....I stopped taking everything for a while when I was working on getting my nutrition down, because that's what dictates gains for the most part. You would have better results doing the same. Keep a positive attitude; all of this is
constructive criticism.
Because creatine is so cheap, I am going to go officially on the record as saying that I disagree with AC.
Dave, what you're talking about is very, very insignificant. Diarrhea only occurs when people OD on creatine. The dehydration is an important issue, but drinking too much soda or eating too much salty food can dehydrate you also. In fact, a high protein diet is dehydrating. Consuming a little extra water is not too difficult. Besides, this affects very, very, very few people and it's been mild in almost all cases.
