I know this question and answers are some years back but having the same issue. With a new manufacturing company called "ANI" that Walgreens is going through now for my D-AMPHETAMINE ER 20MG SALT COMBO CP. I've taken this particular dose and medicine all my life since teenage years and I am in my 40's now. My adhd symptoms taking this one from this pharma company have became worse and feels like nothing in this pill is even close to the generic version of Adderall at all. I am more in my head and fatigued. My research shows this pharma just purchased another company and my concerns are how is the potency in their product checked before distribution? Is it checked by FDA every sell and shipment they make or annually? How easy is it for Pharma Companies to cut corners making medicines to save money at the expense to human mental and emotional well-being, so they can make these big purchases other companies then immediately go back to the FDA approved formulas when they know they will be checked and inspected?
