If you can't get the creatine supplement then this weekend load up on red meat. Roast beef, hamburgers, steak if you can get it. You can get creatine natutally from red meat and chicken. If you haven't done so already drink your omni drink on sat so the creatine in it can be processed by your body. Based on your smoking history you might make it with dillution. Follow the dillutio sticky excpet skip the aspirin and sub gatorade for water the day of the test. Do not use you morning void and urinate at least 2-3 times before taking your test. Good Luck.
