I got a bottle of liquid cialis from
www.ag-guys.com and wanted to try it for training. So, I take 4 or 5 drops about 1/2 hr before I go to the gym. What I found was an amazing pump when I did Chest, so I tried it for delts and arms and the same thing happened. Theory being that if it drives blood into the area that you are using, you gorge it with blood and it pumps. It's not only just good for sex but any muscle that you are working.
Give it a try. I'm using it every workout for awhile.
