adderall + mast + winny = shredded.
i'm sure i'll get flamed for suggesting this, but adderall is a lot safer than clenbuterol and t3 which are used WAY too often to cut...
adderall is mostly dextroamphetamine, which is just about the most powerful appetite suppressant known to man, plus amphetamines will strip water off like mad, the big issue i think here is going to be BP and hydration.
watch BP closely (daily or EOD monitoring) and stay very well hydrated (and not just water, need a lot of electrolytes, something like a high quality sports drink/pedialyte should be consumed during workouts to especially cardio, adderall can crush electrolyte levels)
adderall is a stimulant therefore a dopaminergic agent, it will cause a seesaw prolactin effect, it should initially reduce prolactin levels, but at night the levels will rise... shouldn't be any cause for concern with winny/mast in the mix however, i also take adderall for ADHD and have used it on and off cycle, it's not the best for a bulker, but it makes cutting a BREEZE, seriously paper thin skin on winny/mast/amphetamine... inside out time. There are also a few studies suggesting that amphetamine can be anabolic, you just have to get around the anorectic effect.
amphetamine is much safer than people think if used in therapeutic dosages, it does substantially raise BP however... also AAS will enhance the effects of adderall (he may want to take less to avoid insomnia) because it increases tyrosine hydroxylase expression in the striatum and pfc, allowing the body to convert more tyrosine into dopamine, which will result in a stronger response to adderall and should actually mitigate some of the neurotoxicity of adderall. just make sure he doesn't abuse it...
