I was on Androgel for like 3 years, at the beginning I felt good results cause my natural test was at 197. After a while that feeling I had when I first started using Androgel went away, I started feeling sluggish, loss of libido, moody all the time, that's when I started doing my own homework and found out that my estrogen was trough the roof, I contacted Chip and will be working with him in the near future. I would never use any type of gel in my life.
