TMA-6 is a dud compared to many other RCs.. Crack sucks, and heroin is HIGHLY over rated. You probably wont even really like heroin your first time, or even first few times. It's SO fucking addictive because of how good it is sneaks up on you and grabs you, never letting go. Have fun finding out for yourself...it's just another opiate.
....i love opiates.
EDIT - i think most people that posted on here are so interested in heroin because of all the stigmatism surrounding its use. It's really not that interesting or euphoric...hardly euphoric in my opinion...from shooting the initial rush is heavenly, then for the remaining time, your standard opiate high, but a little different, cause all opiates are SLIGHLY different.
