UreaSample.com substitution for pee...any experience or tips???

Hey guys and girls, I just ordered some freeze-dried human urine from UreaSample.com

I was wondering if anyone has used this product before and if it worked...I read in another thread that it does, but I'd like more input. The test is done at a hospital lab, but I think they only test for metabolites and do a creatinine to make sure it isn't diluted.

Let me know! Much thanks!!!!!!!

no?
