Regardless what you or I believe, people have great effects with ZMA. You hear it all over the forum. Only complaint I have heard is “too vivid of dreams” as told to me by Ian King. He liked it but gave him freaky nightmares. How do you know B6 alone has the same effect for everyone? I believe there is a certain synergy involved. I like it so I take it. I promote it to my athletes as well. They all seem to have superior results. To each his own, but I think there is more than enough “positive personal experience” to support the use of ZMA. Most people on this forum are in tune with their bodies, so I take them at their word when they say it works. As far as liscensing, I just know that you need to have SNAC approval to use ZMA TM. I have spoken to Victor on the phone before about it.
