Actually, labs can detect a "non-human" urine sample without breaking the bank and staying within the letter of the law at the same time.

A "non-human" sample is ruled when the creatinine level is 0 - 2 mg/dL (creatinine readings over 20 mg are acceptable). But as long as the synthetic batch is not expired, and been stored properly (ie no exposure to direct sunlight), there'll be nothing to worry there.
