robdog, round steak is a cut and a cheap cut at that. That kindof meat needs to be used in the pressure cooker or maybe the crock pot. I dont like those cheap cuts but zinc is in all beef. I eat alot of meat so I dont think I can be deficient in that one. But at night before bed might boost test levels and with me going post cycle in less than a month, dont think I have not thought of that.

I have read somewhere that a mans climax makes him lose some zinc so if you are having alot of orgasms then supplementing zinc might be a good thing.
