Substitution Question

Hello, I just took my first drug test using substituted urine. Everything seemed to go fine, but there is something that still nags at me. On the way to the clinic I decided to heat my sample with my car's defroster. I didn't realize that it would be so effective. I heated it quite a bit higher than I planned to, somewhere around 111 and 112 degrees. I let it cool back down before going in. I was just wondering if heating it too much would in some way be damaging to the urine, and if so is the temperature I got it to too much. I'm probably just freaking myself out. Can anybody help put my mind at ease?

it will not damage it, it happens to people all the time when they microwave it a little to long..

Thanks. That's exactly what I wanted to hear. I figured I was being a little to paranoid, but mary jane will do that to you.
