4/5
I was skeptical about such a simple product as Recover ZMA. After 30 days use I'm a believer!
Sleep:
Sleep rebuilds muscle and this stuff works well in that department. Had consistently good nights of sound sleep during the entire log. Woke up refreshed and not a bit groggy.
Workout Quality
If you sleep well you rebuild muscle and are able to have quality workouts. I had 16 new PRs while on this supplement. I couldn't believe it myself as I thought I would become immune to its effects! Well you can't argue with science!
Thanks again for looking and "get some great sleep so you can lift something heavy"!!!!
