Is this amphetamine sulphate (speed paste) the exact same thing as like Adderall or Vyvanse? I'd assume so mg for mg since they are all just amphetamine (whether it be dex or coupled to a lysine in Vyvanse's case). So if this is the case, would it be reasonable to cap up 50 mg of the paste and sell it for $5-10 as essentially an Adderall? Is there anything dishonest about this? Will this 50 mg speed paste give the same subjective effects that about 30 mg Vyvanse/Adderall would?
Speed is usually a 50/50 mix of levoamphetamine and dexamphetamine.
