I ended uo getting used to the Biotest ZMA, that first week though was very sleepless. My only guess was that my body was able to notice a difference between the types of Zinc being used? (A lame guess to be sure but everything else was pretty much the same, well the same as much as having 3 kids can be).
I hate to say it but I do like the Biotest ZMA much better than the GNC stuff, not to mention the fact that the Biotest stuff doesn't STINK like I have no idea what!
