I started HRT last July with Testim gel - 50mg. Unhappy with transfer risk, I asked to be switched to
Androderm patch . . . my skin said, "No! No!" It took weeks for the welts to disappear. Then we tried injections of t-cypionate - 100mg per week. It was great for about 4 days after the injection, and then the bottom fell out of my T-boat. Same drill with next two injections - I felt like I was on a roller coaster ride. The downs were nasty - erectile problems, lack of energy. When I did some research on cypionate, I discovered that the half life is about 4 to 5 days, which would explain the problem I was having. My doctor was not willing to give me more than one injection per week, so I returned to Testim, but at 100mg. To alleviate the transfer risk, I apply at night before bed and shower in the morning. It isn't perfect - I'm still trying to deal with over-aromatization, but on average, its a much smoother ride.
Some forum contributors suggest that injections be given every 4 to 5 days to avoid the roller coaster effect. I'm sure you can find some posts on this forum regarding more frequent injections.
Best of luck to you.
