One study had "evidence" that it increased testosterone, but that study was done by ZMA creator, Victor Conte of BALCO infamy. The study has been discredited and has never been duplicated.
But the placebo effect is often just as real for those who feel it. If you believe it's giving you better sleep, then enjoy. Only thing getting hurt is your wallet.
I get asked all the time why I don't post in the fitness and supp threads anymore and it is because of posts like this. The calming effects of magnesium and calcium were well known way back when I was a just a kid which was a long time ago. I am sure you could come up with all kids of examples right here at the planet. About 6 months back Iherb sent me a few complimentary packs to try. A deeper undisturbed sleep is immediately noticeable as well as the ability to sleep longer. I usually can only sleep 7 hours but I can sleep up to 10 hours after taking the product and yes because of that you definately have more dreams you remember. I bought a couple bottles and have turned friends and family onto it and have recieved the same feedback with one even dumping his sleep meds. You certainly will not be bringing a tranquilizer to the party but the effects are very noticeable.
On a supp note I have to say I love using nitric oxide. I got a bottle of vitrix the other day as I was told the product was amazing. It's like walking around at 16 again with a boner. YOu want to **** until you draw back a bloody stub and have unfriggen believably strong orgasms you gotta roll with that combo. I like their t-up product as well with a little reversitrol when cycling down.
