I don't see how creatine would help w/ drug testing.
Apparently, you didnt read my post. If my post has no effect, then read the Dilution sticky thread or make use of the Search button, using terms creatinine, dilution, drug testing. And if that doesnt do you any good, then make use of your preferred search engine.

Creatine is an effective way of having energy available throughout "oxygen debt". Oxygen debt occurs in your muscles, 10 seconds after working out. During these 10 secs, all the available ATP is used up. After this period, the ATP to power your muscles is created anaerobically (inefficient). Creatine (or I think creatinase) is used by your muscles during Oxygen Debt instead of ATP, for energy. This means extra strength and endurance for whomever is active.
I dont see how any of this has anything to do with the topic of drug testing.
