There's no way that the variance allowed is +/- 20%. That's insane.

Does that also imply that a 30mg Adderall could come out as either a 24mg or a 36mg? In reality that is likely easier for the manufacturer to detect than the individual weights of the active ingredients in a random mixture, but still.

They measure maximum blood concentration and other parameters. Not just how much of the primary ingredient. But the variance allowed for those parameters is 80% to 125%.

I see, that makes much more sense
