Hrmmm. Interesting. I was under the impression that you had dexadrine, methamphetamine, and methamphetamine salts, and that was it. Dex was no bueno for me – it was an aggressive, over-caffeinated high and the downsides outweighed any benefits, for me. Pure meth (prescription form, of course) was okay, but meth salts were where it was at, for me. I’ve never had a name-brand version of any of them, but I’m not expecting that to be some magic wand.
If anything, I would want a stim that was fast-acting with a short-half life – take it in the morning, get a good, productive 4 or 5 hours in, and coast through the afternoon without turning my legs into stilts. This rules out the extended release versions of any stim, so I’m not sure what’s left for me.
