Testosterone
"Following a radical prostatectomy in 2006, I started using Axiron in April 2013. Within 3 days, immediate improvement in sexual performance to like prior to surgery condition.  Sex went from once every 1-2 months to 2-3 times a week. My wife said "what's gotten into you"? Even on some occasions Erectile Dysfunction pills where not even needed. Lately it seems the effects have diminished for unknown reasons. I'm healthy, eat a good diet, I do a power walk 5 days a week (4 miles) and lift weights 3 days a week. I use 30 mg under each arm once a day. No irritation issues. I'm just hoping the feelings of when I first started the medication returns."
