As I understand it, you have cut out 50 mcg of T3 and you replaced it with one grain of Armour. The net change is minus 41 mcg of T3 plus 39 mcg of T4. The half life of T3 is less than a day so you will feel the full effect in less than a week; however, the half life of T4 is about one week, so you will not get the full effect of the T4 for 4-5 weeks. So be aware that one week will not be indicative of the overall effect of the change.
An update: I realized I was having mild hyper symptoms so I cut out 25 mcg T3. Then my dr called and said I could go to 5 grains but to cut out the cytomel. I’ve been living on T3 and obviously this is less but the added T 4 may make all the difference. He wants me to call him next week to see how I’m doing on 5 grains.
Decided to write to my doc since he’ll probably get my letter the day he gets the results.
In spite of your doctor being reluctant to increase your NDT dosage, it seems to me that you FT4 and FT3 are out of balance. You are not taking enough NDT to get your FT4 to mid-range, and the additional T3 med is pushing your FT3 to top of range and slightly above. There is adequate T3 in NDT to do both, if you raise your dosage to 5 grains. That should not be a problem. I recall reading somewhere that the normal dosage of NDT ranges from 3-5 grains. Five grains should not alarm your doctor if he realizes that your FT4 will increase but your FT3 will decrease slightly. Before considering doing this I do think you need to know your Free T3 to RT3 ratio to see if you are converting too much T4 to RT3.
In addition I am not very knowledgeable about ferritin and iron problems beyond its effect on thyroid. I do wonder about your ferritin level being 226, without even taking any iron for a week. How much iron were you taking?
Also will be interested to see the results of your saliva cortisol panel.
Before going in depth, a couple of questions. What time of day did you take your thyroid med and what time was the blood draw for those tests? Do you take any iron supplements that might cause the ferritin result? I know Kaiser is reluctant to do more than absolute minimum testing, but have you had a cortisol test? It would also be good to test for Reverse T3 and a Free T3 from the same blood draw.
It has been 3 months 2 weeks since my last post when we added cytomel back in. Here are my current labs. I have been taking four grains NDT and 50 mcg cytomel. My Ft4 is finally in level but just barely. My Dr used a math formula which he said is proving reliable about about whether or not I'm getting enough. After I left his office it occurred to me it was the reverse T3 formula. I don't have reverse T3. Can I get an opinion on the iron. I think this all looks good but if anything is off please let me know.

All labs in normal range, except for one liver that was high.
I am 53 years old and still having regular periods until last month. This month is the second one that is late. I have been having warm flashes throughout day and night that last about a minute, but not sweating. I sleep terribly and wake early.
My resting heart rate is in the 90s sometimes. I've been tired and lacking focus. I think my hair loss is improving but not sure. Craving sugar, lacking motivation and joy, living on caffeine and not feeling interested in the things I normally love. I would like to get the Ft4 up in the range before treating for depression.
Any thoughts?
The first thing is that I don't expect the herbal supplement to help with your symptoms.
When you were taking 3 grains of NDT and 55 mcg of T3 that was equivalent of 365 mcg of T4. When you switched to 4 grains of NDT that was equivalent of only 264 mcg of T4, which was quite a drop. Seems to me that what should have been done when you were still taking 3 grains of NDT, plus 55 of T3, was to go to 4 grains of NDT, and keep 25 mcg of T3 also.
After finally finding out about the importance of Free T3 on symptoms, I got my doctor at that time to switch me to desiccated thyroid med and gradually increased dosage until I felt better than I could even remember. I was taking three grains at that time. Now after a number of years I have developed resistance to thyroid med and in order to relieve symptoms I am currently taking two grains of NDT and 87.5 mcg of T3. If I convert that to equivalent T4 it would be almost 400 mcg. Your 4 grains of NDT would be the equivalent of 264 mcg of T4. So quite a bit less than my dosage. My doctor is the one who stated that, "dosage is irrelevant, only the physiological effect matters."
I think you should emphasize to your doctor that your FT4 and FT3 levels should both be in the upper half of their ranges in order to relieve hypo symptoms. And that as long as those are within their ranges, dosage should not matter.
My doc asked me to try an herbalm tonic which he thinks may help with symptoms. I didn’t think to ask about the T3 when we spoke on the phone. None of the increases of T4 show on labs. Now FT3 is low normal and certainly not
optimum. I think I’ve been living on T3.
He is usually open to trying anything and is a proponent of NDT and doesn’t go by labs so much as how I’m doing. However, he is not comfortable going up higher because my T4 hasn’t moved.
I wondered if anyone here saw improvement only at a higher dose. He may be interested in that.
The doctor is fearful of 4 grains of Armour not based on bad experience, but lack of experience, I expect. With your symptoms and your very low FT4 and FT3 at only 38% of range, you could stand a dose increase, not a decrease. An excellent thyroid doctor once told me that dosage was irrelevant, only the physiological effect matters.
Are you waiting to hear from the doctor?
I have not stopped having these symptoms for years. I haven’t been normal for so long, I’m not sure what it looks like any more. My FT4 has been below range for a year or more. My FT3 has been at the top for at least that long or longer,
Also meant to ask if the symptoms you mentioned have changed with the dose change?
When you changed your med/dosages, what was the new dose of T3?
Before trying to answer those questions, please post the actual FT4 and FT3 results and reference ranges shown on the lab report. Also, do you split your dose and take half in the a.m. and the other half in the p.m.? Did you defer your morning dose until after the blood draw for those tests? Same question for your prior test results? Do you take your med an hour before eating? What are your Vitamin D B12 and ferritin levels? Even more important than tests, what symptoms do you have?
