I have been reading threads from here and from various other sites in reference to my thread topic "CorePharma" vs "Barr" Generic Adderall, and I absolutely NEED to vent! I am so frustrated to read how some pharmacist, scientist, etc... have responded to this discussion. I have had the worst three weeks since I started on Adderall-- 8 years ago. I picked up my last prescription at a different pharmacy. I usually receive Barr brand but was given CorePharma brand this month. All I want to say is-- this "particular" generic brand "Amphetamine, Dextroamphetamine Mixed Salts", is absolutely NOT equal to BARR brand generic "Amphetamine, Dextroamphetamine Mixed Salts". This is NOT psychological, this is physical. I have been depressed, have had constant headaches, been unmotivated, unfocused and have had an overall feeling of unhealthiness. Unless my health "condition" happened to deteriorate the VERY day I took my first dose of CorePharma, than there is no other explanation other than the one I have concluded. The bottom line of this post is-- The MAJORITY rules, CorePharma Amphetamine Salts are substantially INFERIOR to Barr brand Amphetamine Salts.
