Heating your gear to prevent injection pain is the biggest crock of sh it....most of the pain is several hours later from the gear itself...not the actual injection...

Whoever thinks that makeing the temperature equal to that of their body in effort to lesson the injection pain shouldn't use aas in the first place...

I have used prop that was smooth as butter going in and crippleing the next day...o no...if i only warmed it...lol

On the contrary i've used prop that hurt like a bitch going in and nothing the next days...I guess those were the days that i warmed it...
