People do ask questions about supplements whether they are healthy or do they harm the body?
I want to know how the human body responds after taking "fitness" supplements with creatine.
I know it's hard to generalize the effects, as our bodies differ from person to person. But again, I'm really interested in this subject and I want to study it more.
So instead of asking a book recommendation, I'm asking where to begin to study the subject. Keep in mind that I want to study the theoretical part of the substances before taking them.
