First, let me say it takes ballz for a company to actually START a thread like this. Second, my number 1 favorite supplement of ALL time is USP's CissusRx -- I honestly value it more than creatine, protein powder, or my multi-vitamin, because I just can't workout effectively anymore without the joint support that Cissus provides.
But the fact is, PowerFULL does nothing for me -- it might as well be a sugar pill. I ordered the original "buy 4, get 1 free" red cap Muira Puama stuff -- Lot #039467. I've always taken it on an empty stomach, usually stacked with my Cissus. I've tried 2 caps, 3 times a day; and 3 caps, twice a day. I've even tried mega-dosing (something like 9-12 caps -- I forget) right before working out and right before bed. And I've never felt anything at all. No pumps, no deep sleep, no vivid dreams, no libido increase, and certainly no strength or mass benefits. I'm definitely a TOTAL non-responder, but I've decided to just keep stacking it with my Cissus, simply to get rid of it.
So...
I won't be ordering anymore PowerFULL, but I'll never stop using Cissus. And my mind is still very open to other USP products. This thread only reassures me that USP is a good company that cares about its customers.
