I was placed on that and didn't feel much different. In checking the #'s I only went up from 210 to the low 400's. My doc then placed me on Testim (the little tubes) and I got much better results, into the high 5's, low 6's. The dose is about the same as the pumps, but for some reason, the Testim boosted me up more.
As for effects, my lifts weren't really affected, but I definitely have more energy and, well, horniness, with either gel. In that respect, the stuff works great.
