You should consume at least one liter of water (about 2 pints) within 45 minutes of consuming any creatine monohydrate powder. At no point should you take more than the recommended amount, which is 5g of 100% creatine monohydrate.
Also, you can take the 'loading dose' over a period of time. You should also drink lots of water. Creatine binds with water, pulling it into the cell and pushing out acidic waste products of metabolism.
To take it all at once is like eating your total dietary intake at one meal. Possible, but generally a stupid idea. If you are using supplements, know what you are doing before you stick it in your mouth.
Powdered creatine is over 20x more dense than creatine in natural sources (e.g. meat). Use with caution. Drink lots of water.
Did you notice that you should drink lots of WATER?
Yes, not juice, not power drink, not beer, but water.
If this seems unclear, read the post again. Twice. Out loud.
