I have Hashimotos and been on thyroid medication for several years now. I made the mistake of not checking reverse t3 from the beginning. After finding out I had very high RT3, (which actually counters free T3) and is caused by my body converting t4 into RT3, I now take compounded sustained release T3 only (no T4 at all). I take 25 mcg twice a day 12 hrs apart. RT3 is now low where it should be and it has made a world of difference. The brain has the most T3 receptors of any organ in the body and T3 is vital in controlling emotions. It helps to control depression and anxiety and mood. Also on trt sub q E3d plus HCG every other day. No Ai needed but do have problems getting my E2 up into range of 22 to 32. HCG plus DHEA will increase E2. Was on transdermel Test, but became hypersensitive after 2 yrs and both test levels and E2 went through the roof. The switch to sub q injections more frequently solved all of my issues. On the transdermel Test I had to take Anostrazol to control E2. Now I have to work at raising my E2 to get to normal levels. Proper E2 levels are absolutely necessary for good nocturnal erections. Which then indicate your body is in good hormonal balance.
Interesting . . . I was just prescribed compounded sustained release T3 (from Empower), however my doc told me to start at 10 mcg once in the morning for 2 weeks, then increase to 20 mcg depending on symptoms, up to a max of 30 mcg. Never said anything about splitting the dose in the am/pm. He actually made a point of telling me to take it with water first thing upon waking and then wait at least 30 min before eating/drinking anything else. I'm now wondering if I should question the doc further on splitting the dose. Or maybe when I get the delivery I will give it a try with just the am dose, and see how I feel in the evenings as my T3 levels will presumably drop?? This Thyroid stuff is very complicated . . .
