Really happy with my T3 level now,but,would I benefit from more levothyroxine,as my T4 might still be low?
Only you can say. When on combination thyroid hormone replacement it's very individual where we need each hormone level to feel well. What's right for me may not be right for you or anyone else. So all we can do is experiment, gradually tweak doses if we feel it's necessary, keep a note of how we feel on each dose, whether any improvement or not, then you will be able to find your own sweet spot.
Don't forget that increasing your dose of Levo will increase your FT4 level but, depending on how much natural conversion you have then it can increase your FT3 level as well.
