I am thinking about using creatine and i need to know more about it?

i am thinking about using creatin but i dont really know much about it.
I need to know more about what it does to you. good and bad
i need to know when i should take it.
i need to know how it does what it does.
and i need to know about how much it costs.

Take twenty grams per day for one week.This is referred to as the loading phase. Then take 6 grams per day for 3 months. This is the maintainance phase Followed by one month of none at all. Then repeat this cycle.

You take it before and after exercise.

The main benefit of taking creatine is that it increases muscle development. Some studies suggest by as much as 17% There are no known side-effects. (Creatine is a naturally occuring substance within the muscles)

As for the cost I recently bought a weeks supply for the loading phase for £10. And 120 capsules for £14.99, for the maintainance phase.
