Amphetamines dont "feel different to me now" - different preperations of the same drug feel markedly different. Name brand adderall and sandoz generic feel the same as they always have. Actavis feels like I am geeked the fuck out. Honestly feels quite similar to the effect of eating the cotton out of benzedrex inhalers (please, no judgement, I was very interested in drug experimentation as a youth) I did look into the stereoisomers of generics per your comment - you are correct, the fda does regulate the specific enantiomers present in a mediciation. So I am at a loss. I am certain Actavis specifically is chemically different. Perhaps there is an inactive ingredient that is modulating the effects? Or perhaps Actavis is just lying to the FDA. I would love to find some 3rd party which does evaluations of chemical makeup for generics. Was unable to find such a thing, if you know of something like that, id be very interested.
