Methylphenidate right?
last time i did that, and this is llama do amphetamines 2-3 times a week for a long time, i was having TERRIBLE chest pains, i wasn't freaking out (other than the crackhead high you get from it...the paranoia....) but i see how that can be freak-outey
methamphetamine>pharms IMO, feels cleaner too, honestly feels more noob friendly long as you dont do much, my friend didn't freak out from bumpin some meth and he's got no amph tolerance...but i made sure he only did a tiny bit so who knows.
