Well, when I was using Nor-Andro Spray, I was spraying it all in one area. I'd do 5-6 sprays, then blow some air on the area, then do another 5-6 sprays. I got great results from just doing that. I was spraying it on my chest and stomach area. If you chose to split it up to different areas, it should only makes that much better for you I assume. I mean, the only problem is that you'll have more areas of your body to worry about having the spray rub off on to your clothes
