seems like a good multi vit. would do better job of supplying those ingredients

As far as test boosting goes ZMA is crap. But the ingredients, zinc, magnesium, vit b-6, are all essential to lots of bodily processes and are very beneficial. Tough workouts deplete these nutrients so supplementing with ZMA is a big help. Its good for improved sleep, gastrointestinal health, overall daily energy, and can help with tense muscles. I take it too but its more of an addition to my multivitamin stack than anything. Good stuff, but don't spend more than 10-15 bucks on it. Supp companies will rip you every chance they get.
