T3 can help the whole HPTA?

I don't know where to ask so I will ask in some places and when I get answered I will delete

I'd like to know if fixing thyroid issues the pituitary will release more hormones like LH, FSH, ACTH. Because I saw many guys saying once they fixed their cortisol deficiency the RT3 decreased, the TSH decreased too (without thyroid meds), LH and FSH increased so their testosterone, E2 and thyroid became better.

So my question is when free t3 really reach the body cells does it increase the pituitary function? Can it increase also the ACTH? Because I want to go to HC treatment due to low cortisol but I don't want to stay on it for life.

TSH:3.5
T4 1.2 (range 0.8 - 1.7)
T3 3.3 sometimes 3.6 (range 2.4 - 3.7)
Cortisol Am - 95 (range 100 - 640)
ACTH - I have two tests one is 14 and the other 32 (range until 46 pg/mL)

To be clear. I'd like to know if T3 can help the HPTA function better like sending more hormones when necessary etc. Tweet
