I also love it. I use it on a daily basis for the visual enhancement. I also notice that it me build / maintain some strength throughout the season.
I just started a new approach. I take 3 caps morning, afternoon, and w/ ZMA at night.
It is very possible that people with bad experiences are simply not taking enough. I have heard / read that Methoxy-7 is best at or (although not recommended) above the maximum dose. At 9 caps p/ day (1 above the max) 2 bottles will last you 32 days.
