Using Friend's Clean Urine For drug test

Okay I have been perusing so many forums on this.
Background: I smoke regularly, fat, and went to a job interview on a whim because they were doing massive hires NOW.

I have a friend subbing for me. Wanted to run logistics behind things with you guys and see what you think:

I have an appointment with LabCorp, lets say at hypothetically at 6 p.m.
at 5:30 p.m. I am going to retrieve the urine.
My drive is exactly 5-7 minutes depending on traffic.


Should I just buy Thermacare pads, wrap them around the 3 oz twisted portable jar, and immediately go into the testing site with my appointment ?
Or should I, in that little span of time, use time to get to a microwave and heat for 10-15 seconds, and THEN head over at like 5:55 p.m. with little time to spare ?

I am leaning towards the first idea. Get the urine. Secure it. Keep it warm with pads. Put it in my gouch area, and then go in straight to my appointment.

Thoughts ?? Greatly appreciated !!

Its happening tomorrow so I would greatly appreciate the advice !

 

it all worked out. Posting a thread now so people can see it as a success story and add to the dialogue to make the process better for others. Thank you it was a crazy idea.
