Mate, me calling you a smart ass had nothing to do with your original question, it had to do with your smart ass Balco remarks. I never said your question was stupid. I was genuinely curious as to what you thought ZMA (basically a multivitamin) was going to do for your production and recovery.
Most questions to do with supplements and roids are based around M for estrogen blocking and Alpha Male for the reasons listed above. The only thing I've ever heard ZMA being used for is aiding sleep. Every Waterbury says in his last two articles "If sleep is a problem, you need ZMA", or words to that effect.
So, if they are your reasons for wanting to take it, take the damn thing. The magnesium will be good for CNS recovery at the very least. The roids should be all you need for muscle recovery.
Anyway, take some and get a good night's sleep. You'll be less crabby in the morning.
