Androgel is the best transdermal, hand down. Problem is you need a prescription from your doctor and it's really expensive. If you look around online you can find some generic versions of it. Also your doctor won't give it to you if you have semi-normal test levels. Anyways, I started using it and my testosterone levels were great. It's hard to find though, androrxshop is where I've got mine in the past. Pretty inexpensive. Good luck.
