FBR and BurntToast are correct and I stand to correct myself with what they said. I guess I knew what I meant to say, but I guess my fingers said something different. Labs do look for creatine AND specific gravity to determine dilution. I would still load up on creatine 2-3 days before any real test. Creatine Monohydrate is relatively cheap for a large bottle. The tums/rolaids/salt every hour will help with SPECIFIC GRAVITY.
