Low estradiol is something to avoid, just high estradiol is to be avoided. Frequently men at the commencement of TRT find themselves with low E2. As therapy progresses levels will typically rise. I would NEVER use testosterone undecanoate. It enters the body and levels jump, as can estradiol. Despite what you seem to believe, you will never get a steady-state level of testosterone with it because you are on a modified roller-coaster ride. Dr. Saya's response that I posted earlier states that in order to achieve true, steady-state serum levels it is necessary to inject very small amounts of testosterone on a daily basis. Most men do not need to do this, they achieve excellent results on every 3.5 day injections, or every other day injections. I went for a radical solution, so to speak, and am glad I did.
