It's a quick way, but a very ineffective way. The Creatine that these drinks contain is absolutely useless. Creatine must be loaded 2-3 days in advance in order for it to metabolize into Creatinine. This is one of three validity checks they do to see if your diluted. The other two are color(vitamin B2 remedies this), and specific gravity(substitute Gatorade for water). The dilution process is not something that is completely effective at the last minute. Yes... It worked for you, but who is to say it will for someone else. That's why I'm so persistent about factual information in the drug testing forum. Your recommendation of Q-Carbo here could land someone in the unemployment or worse jail and I won't let that happen.
