Where can you buy home test kits?...I have been practicing all weekend with a two ounce bottle. I have been filing it with room temp water and seeing how long it takes to heat up to 95 degrees. The way i've been practicing is by wearing two pairs of boxer briefs and placing the bottle just behind the balls and between 1 hour and 1 and half hours it warms up to 95 degrees. I wont be picking up the specimen till one hour before my test just to make sure its fresh and already warm. Before i go into the test I will of course take the temp of the substitution and make sure its correct.
