from what i've heard it is manufactured to calibrate drug test equipment, though i don't know if that's true.

so, yes it is good so long as you give it to the lab tech at the right temp and don't sign forms that allow genetic testing...it doesn't contain IgG, which is unique to human urine (afaik), but will not be tested for unless you consent.

i beleive the shelf life is around 2 years, unless exposed to sunlight. it can be heated daily without degradation.
