BZP probably, but im lucky, every alcohol store etc sells pills containing bzp/tfmpp. piperazines are shit, but its legal here and are better than anything other legal stimulant ive tried
Haha, yeah, I'd say caffeine, too. Order some Guarana powder (not the pills, the actual powder) and mix a big spoonful into something to drink. You'll definately have some extra energy. Oh, and try some Kratom, too, although it's a little bit more pricey.
