So obviously this is a controversial one to some degree. It is an amphetamine, and a halogen substituted one at that. Not to mention the rather "scary" name, which contains the word methamphetamine.
Regardless, I figured I'd throw in my two cents.
I've had a chance to try some small quantities, and I can say it behaves the most like a nootropic out of any amphetamine I've tried. It is much less euphoric than regular dextro-amphetamine. Also seems to largely lack the "tweak" factor, aside from mild bruxism (at 30mg), and have fairly minimal effect on heart rate. It does on the other hand have "focus inducing" properties to a similar or greater degree than d-amp, and is very good at wakefulness promoting, especially synergisitically with Adrafinil and Caffeine in very low doses. The half life is also relatively long, I usually notice effects for a good 10 hours before they seriously decline.
The big question, and a reason I'm hesitant to use it too much, is how toxic is it?
I've been stacking with Aspirin, Vitamin C, CoQ10, Methylene Blue, Sodium Butyrate and PQQ to help combat possible neurotoxicity, and using only occasionally.
Any input?
Edit: Also worth pointing out that I think this would be a rather difficult chemical to prosecute under the federal analogs act, as I think it differs enough in effects to not be considered "substantially similar" to a Schedule II substance, think USA v. Damon S. Forbes et al.
