yeah, i did not hold off and was kinda worried that it may come back diluted, as i drank a little over a gallon that morning. But, i took the omni near test time and it does contain creatine. Its only like 250 mg of it but i think it worked as i was pissing just water, and maybe some coffee reminaints. So yes i passed, i think they might have hit it with gc/ms because it took a little while to get my results.
