My Thyroid numbers

I'm doing great just sharing for the larger discussion that can be had, for others to learn.

I've been supplementing with T3 in the 5-10-20mcg once or twice per day the goal being to push my RT3 down a little bit for fatigue.
Have tit-rated the dose over the last month. I've lost a few pounds without directly trying to, down to 213 now. Have been sweating more in the gym which is a noticeable difference. Also less yawning or tiredness thru the day. The most I have taken is 20mcg twice per day about 10hrs apart, no jittery feeling or anything like that, just feel better.

I didn't run antibodies because that has been run before and is not a problem. Low FT4 doesn't seem to be a problem per se.

May 2019
TSH 1.47
FT3 3.9
FT4 0.8
RT3 14

TSH (0.40-4.50)
Nov 2017 = 2.37
Jan 2018 = 3.15 (I believe this time I was hitting Iodine and Selenium that inflated TSH)
Jan 2019 = 1.97
May 2019 = 1.47

FT3 (max 4.2)
I ran 3.6 - 3.9 from Oct 2014 - May 2019

FT4 (0.8-1.8)
I ran 1.1. - .08 from Aug 2015 - May 2019

Reverse T3 (8-25)
16-14 from Aug 2015 - May 2019
 
I am surprised your RT3 is at 14 given the 40mcg of T3. If you are feeling good I would just stay there for a period of time. I am up to 75mcg per day split 3 times myself and think it is a bit much getting labs tomorrow.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
