I would never take any T3 on your own if I were you, because of your issue. If something is wrong and your natural levels are low then see an endo and have them help you out. Sounds like you haven't taken much and its been awhile so it probably didn't do much harm but I wouldn't go there again.
As far as taking the HRT dose of 80-100 mg/wk causing an issue I don't think it should. If it were a danger then my cardiologists would have all said no. Only danger is your hemoglobin/hematocrit getting high but you can correct that with a phlebotomy every 3 months or as needed. Right now, and for the last 8 years since my big heart attack, ive been taking 100 mg/wk test and getting a phlebotomy once every 2 or 3 months. He keeps my hemoglobin around 15 which is safe. Keep an eye on yours.
Now for a reason for your EF going down, that I doubt even your doctor can pinpoint. I would wonder about possible compromised blood flow in a coronary artery maybe? Really hard to say, but if you see a cardiologist on a regular basis then I am sure they have that all under watch. With me, I have been able to maintain if not slightly increase my heart function. Eventually though it is inevitable that my EF is going to start going down as I age.
I was able to raise my EF before I had my heart attack by going off steroids to the point that my heart functioned normally. At the time I was taking the usual big cycle of like 800 test/750 EQ/ 500 Tren. Going off all that shit got me back to normal. That's what happened with me. I had idiopathic cardiomyopathy. After that experience Im almost certain it was the steroids that did it to me based on what happened when I got off.
Have you changed any of your meds? Meds like beta blockers will increase your EF by increasing the filling time of your left ventricle. This is because they lower your heart rate. Did you get off something of this sort? I would think your doctor would be on top of that though. Has your BP gone up? Having a higher BP would increase the workload of the heart and could weaken it if its already compromised, maybe lower the EF. Just some guesses.
For supplements I take Humanofort (3 caps a day) and 200mg Ubquinol 2x per day.
Yea, definitely never touching thyroid meds again unless my endo requires it.
I agree, it seems like it should be no problem...I just can't figure out why mine didn't go up and actually got worse. You took way more than I ever did (longer periods at least) as well as growth hormone and yet you got back up to 60%. Yet I go off and go from 50% to 40%.
My CBC results have always been good, if not on the low side.
The only prescription meds I'm on now are Asacol HD for crohns, Vitamin D 50,000 iu EOW, and 80mg TRT (prescription is actually for 100mg but I brought it down to 4x20mg per week).
I am not on beta blockers or ACE inhibitors...but that may be the next step in the near future depending on what my MRI on 3/1/16 shows. I have no noticeable exercise intolerance in the gym, though I do seem to get a little more tired during some sex sessions honestly....but can sprint and do whatever at the gym with it feeling mostly like it always has. Stairs definitely leave me breathing hard...but they always have as long as I can remember.
I also already have a pretty low RHR (~50-60) and BP (105-115/65-75 most of the time).
I also added cardio in addition to all the supplements I was taking, and cut back on heavy lifting for lower body. I still push very hard on upper body lifts but it was always the heavy squats and deads that made my head feel like it was going to explode and get me near passing out. So my leg training is pretty lackluster nowadays but again that clearly didn't help.
Current regiment:
-500mg CoQ10 as Qsorb (experiment as I just got blood levels checked after taking no CoQ10 for a few months and levels were 0.73)
-1400mg Arjuna
-2-3g Taurine
-3-6g Citrulline
I also take fish oil and curcumin as always. Magnesium here and there. Used to take Ribose, ALCAR, and a few others. Didn't seem to help.
