IV meth definitely potentiates the risk of addiction. Meth became incredibly more enjoyable than all other routes. That is if you experience the rush entirely.
Like I said before 60mg in 20 units of water? No wonder it isn't too enjoyable. I use about 15 units to dissolve about 200mg of the highest quality methamphetamine available. This dose puts me on my ass, disabling me to do just about anything but relax and enjoy. I experimented a lot with different concentrations and the constant rule is more water, even a little bit too much will make the rush noticeably weaker.
I usually add water sparingly in drop increments to the solution, letting each drop expand, then stirring and adding barely enough water for all the meth to dissolve. The solution should appear cloudy and white. Inject as quick as you feel comfortable with, pull back to clean, and push in again, and prepare yourself for a head-ringing rush of euphoria.
And yes, I'm quite aware that I'm addicted to meth. But at the moment I am relatively healthy. I run 20 miles a week, practice yoga, and eat well-balanced meals. I post-load with ALA, l-tyrosine, and take many other supplements.I try not to do meth more than once a week now, and will taper off the frequency as time goes on. Meth is no fun when all it does is prevent withdrawal symptoms.
Julia, come down my way again sometime and I'll make sure you enjoy the IV meth experience.
