Shake and bake isn't worth the effort. It's very dirty with all yur chemicals trapped inside the crystal or paste you end up with. So it gets you high but also burns your stomache or lungs. It's ok for junkies who are going to die soon anyway. :-)Meth is cheap here. $120 /g. Goes very far. Think about it , the work and effort you will go through for small dirty batches ? It's hrs of work. Don't let me discourage you though. It's a fun process. Go with a bitch reduction method. Search for that here on the forums. It's been posted. I stopped buying meth myself. It burns my mouth and lungs smoking it after a day. Even the best stuff. Shooting it up is much better though my pee turns dark brown when using it. It's definitely toxic and other chemicals still in the crystals for sure. It can't be all washed out. It's also why Molly is funny colors. It's too hard to wash it out totally. Speed from p2np is easy too. The speed paste is great. Tolerance builds fast like in a week.
