Well I am prescribed dextro-amphetmine since I have an EXTREMLY high tolerance to stimulants, no adderall, concerta, caffience effects me at all. So I need this shit that is just about as strong as coke from experience and pretty much legal crystal meth. I have 10mg capsules that are time release but you can break them up. Easily can keep someone up 24-36 hours if you take 2+. Anyone ever bought these before? or gave them away? if so for how much?
