So basically I added 5mcg t3 to my 25mcg t4 and had no response after 4 weeks, I’ve upped the t3 to mcg now and lowered t4 to 12.5mcg
Any thoughts I may have rt3 issues?
Thanks

You shouldn't change both things at once because if you notice a difference you wont know what is responsible for it, the lower Levo or the increased T3. You should only change one thing at a time.
For raised rT3 to be a thyroid issue it is caused by a build up of unconverted T4. If you only take 25mcg Levo I think it's impossible for you to have a thyroid related rT3 issue.
When you posted a month ago you said you were having tests done. I can't see that you've posted the results.
Hi: Are you saying the amount of the Levo isn’t enough to cause a rt3 problem? What if a person doesn’t convert t4 at all?

High rT3 can be caused by many things, not just the thyroid. If it is connected to the thyroid then it's due to a build up of unconverted T4. But rT3 doesn't stay in the body long anyway.
It could be caused by low ferritin, or high cortisol, by an infection, by low-calorie diets, etc
Other conditions that contribute to increased Reverse T3 levels include:
· Chronic fatigue
· Acute illness and injury
· Chronic disease
· Increased cortisol (stress)
· Low cortisol (adrenal fatigue)
· Low iron
· Lyme disease
· Chronic inflammation
Also selenium deficiency, excess physical, mental and environmental stresses. Also Beta-blocker long-term use such as propranolol, metoprolol, etc. Physical injury is a common cause of increased RT3, also illnesses like the flu. Starvation/severe calorie restriction is known to raise RT3. Diabetes when poorly treated is known to increase RT3. Cirrhosis of the liver. Fatty liver disease. Any other liver stress Renal Failure. A fever of unknown cause. Detoxing of high heavy metals.
There are many articles about it if you want to read them, here are a few:

I wouldn't bother trying to understand it. Reverse T3 is a bit of a red herring, there are so many reasons for it and only one of them to do with thyroid. It doesn't really need testing, if you want to know if you convert T4 to T3 then when on Levo only you look at FT4 and FT3 levels, that tells you what you want to know. And as I said, rT3 doesn't stay in the body long so you could have high rT3 today but it could measure very differently in a couple of days time.
