Product Overview

We use only the finest patent-pending ZMA that has been scientifically surmised to be 2 1/2 times stronger than a placebo!* ZMA is an all natural dietary supplement that is suggested to support natural testosterone levels and strength in athletes.* Increased muscle tissue growth and recovery can only be accomplished if your body is kept in an anabolic state for a considerable length of time. ZMA will help your body to stay in this anabolic state thereby increasing your body´s overall lean muscle mass.*

In an eight week double blind, placebo controlled study with college football players, ZMA was found to increase total plasma testosterone levels by 32.4%, increase free testosterone levels by 33.5%, and increase muscle strength by 11.6%.* This study showed testosterone levels levels actually dropped in the placebo group overnight, whereas with the ZMA group, it jumped considerably.*

By far the best zma product ive ever used, I get incredible sleep every night

Verified Buyer

It is exactly what it says it is. Honest dosing on the label. None of that "proprietary blend" nonsense. Tells you the form of the vitamins and minerals, which is a must. Really interested to know which one of these minerals/vitamins is known by the State of California to cause birth defects. Seems fishy to me. I'll update this review when I have more information.

Verified Buyer

Amazing product, especially when stacked with 5-HTP (Natrol Brand). I sleep so good that I can sleep for 4 hours and it'll feel like 8. Now, I'm not sure which product exactly gives me that " Recharged " feel but, I will say the combination of them both are great. Also, I only use this brand, I tried using a top brand; didn't really feel the " magic ".

Verified Buyer

I can't say this product has had ANY positive effects for me. NONE of the advertised benefits have been felt. It hasn't done jack for my sleep either. Everyone seems to think this makes them sleep better but I call BS on that. I've slept the same or worse every single night since starting ZMA. I think ZMA is a hoax supplement, propagated by the one and only Jim Stoppani to further line his pockets.


Perfect effect on sleep time.
