Keep us posted on your progress. I believe others have said in took over two weeks for m4ohn to kick in. I'm considering a similar cycle in about a month, so I'm interested in your progress/results. If you have the stuff, it may be a wise desciaion to keep the cycle going for more than 4 weeks. Six sounds about right based on some other posts I've seen. Are you seeing any of the focus/strength improvements from the m5aa? What brands are you using? Hopefully you'll start seeing results by the end of this (3rd) week.
