My name is Mike and I have ED. In April my total testosterone level was 502, but the amount "bioavailable" was only 104. So I need to explore that issue further. In June, after being on Axiron about 6 weeks, the T level dropped to 305, but they didn't run the bioavailable number for some reason. My doctor was trying me on Axiron with 30mg per day. Prior to that I tried Androgel 1% with no noticeable results. I'm 58 years old with no other medical conditions besides an enlarged prostate and ED. So on the Axiron after two months I started feeling daytime sleepiness, and general lack of energy, or fatigue. These are listed side effects for Axiron even if you hope for or expect the exact opposite. So I stopped taking the Axiron to confirm my suspicion it was, in fact, causing the fatigue. Over a month I started feeling my old self again and slowly got energy back. Then I restarted the Axiron and after a month started feeling weakness and fatigue again. So I stopped it again and I haven't seen the doctor yet, but that's my next course of action. I was wondering if others on this board have had this side effect from Axiron. The Androgel didn't seem to cause fatigue, but it wasn't really helping me either. I'm ready to go back to herbal supplements. I got the best result so far from yohimbe tea, but some articles speak to health risks from that too. I thank God my wife also has a low libido or I'd be in a real crappy place right now.
