Definitely gives you lucid dreams and boners in the morning as other people reported.

I stopped taking it because I get enough through my diet now. (Not boners, but Zinc & Magnesium for those that didn't know what I meant)

This pills are addictive. They make me have weird dreams like I am flying on a dinosaur. Just yesterday, I dreamed about being a merman and exploring sunken ships. Five stars for letting me escape this cruel daily living and letting me have psychedelic dreams.

I purchased this mainly for my poor sleep, although I do workout a fair amount. I have narcolepsy and don't sleep all that well. I've noticed that when I take 2-3 of these pills at night I stay asleep and wake up at night much less. The first night I took them I slept the entire night through! This coming from a guy who wakes up on average 15-30 times a night.

I hope this is something that my body can continue to use over time with the same results, because so far it's been near life changing to wake up feeling good!

Did all the dangerous things in life and developed a sleep issue. Tried these while I was in the desert and loved them. Didn't want to use prescription drugs or jam crap down my throat. As far as building mass and burning fat, don't look for miracles in pills... Make it happen in the weight room, outdoors, and eat properly.

I have had to take sleep medications before, but this stuff actually works better than those. Instead of simply knocking you out for a few hours, this blend helps induce naturally deep sleep cycles that can last all night. Because of the better sleep I have more energy during the day. This product really has made an impact on my life.

I did not notice any benefits using this product. However, I did experience UTTERLY INSANE dreams every night. They weren't necessarily good or bad, but rather extremely imaginative and just plane ridiculous. Sometimes I would wake up thinking "WTF why?!" Other than the crazy dreams, this stuff gave me intense cotton mouth and made me feel like a zombie in the morning. Sluggish start every morning and I would feel brain fog for the first half of the day rendering me pretty much useless.

I did not notice any improvement at all in terms of muscle gain or performance. I researched the so called "benefits" of ZMA and I quickly discovered that the ONLY scientific/scholarly article reporting benefits from ZMA was published by Western Washington University. Dr. Lorrie Brilla - The patent holder for his own formula of ZMA who funded the project himself. Several scientific studies have been conducted since then (without bias) which have found no benefit of using ZMA.

I can honestly say that this changed my life. I have never slept better. I bought it because of the reviews about sleep improvement and really ignored the comments about muscle growth.

I have been training hard and eating to gain muscle so I don't know how much to attribute to the ZMA, but I put on about 3 pounds of muscle and lost 2 percent body fat in the last 6 weeks that I have been using ZMA. Hardly what I expected as a 44 year old woman. So between the incredible sleep and possible "gainz" I am jazzed.
