Before you post here telling me what a mistake I'm making; I have experience with meth. I virtually only use amphetamines for studying. And speed paste is absolutely shit for my heart. When I studied on low-dose oral meth last January, it was the cleanest, most useful foray into the stimulant world and I haven't used since.
Any help ?
Why even say d-methamphetamine? I doubt any vendors sell l-methamphetamine let alone know the difference between the two.
