If FBR says its OK then you can pretty much bank on it. I've just never tried it before and was a little leary of recommending it. Its definitely an option for proplr that don't have access to synthetics.
I wonder if you could warm it by drinking it and then just pissing it out? lol:wtf:
killerweed420 Reviewed by killerweed420 on . Frozen Urine Question Hello all..... I doubt very few will know much about this but.....I have some of my own clean urine frozen in my freezer. It's dated 1/22/08...less then a month old. Ive been thinking about using it to sub with. Upon discussing about the frozen urine with another friend I was told that once the urine is thawed it will develope crystals or particles from the freezing which could cause it to fail a drug test after warming it back up. I thought frozen was good for up to a year to use later Rating: 5
