I would say Desoxyn is the cleanest ADHD med there is, it's like all the benefits of the other amphetamines minus the gross side effects.
Dexedrine is much better than Adderall though, and dexedrine is prescribed a lot more than desoxyn so doctors are more comfortable prescribing it.
Desoxyn, made by Lundbeck/Ovation only comes in 5mg instant release pills, they say OV on one side and 12 in the other about the same size as Morphine Sulphate Instant Release.
You usually take it twice a day, I'm prescribed 4x5mg per day so 20mg per day, but I rarely take stimulants, as generally my extremely mild ADD is under control. I like it, I couldn't handle any of the nasty side effects that all the other amphetamines gave me, like adderall and dexedrine make me feel like shit. Ritalin and all the Methylphenidate products don't work for me and feel like a huge dose of caffeine.
Desoxyn is usually only prescribed after everything else has failed, I struggled for years with side effects until I finally found the one that worked.
