well like the other guys said it depends on Alot of other variables...
If you have the opportunity to get you TSH and T4 levels checked that would allow you a baseline for what you currenly have.
High TSH levels typically equate to a low level of endogenous thyroid hormone levels and vice versa...
It also depends on your caloric intake, any supplements your taking, cardio, ect...
There are so many variables..
I'm by no means an expert on T3 but I understand that low doses (12.5-25mg) day improves protein synthesis when on AAS and increasing doses tend to lean towards a more lipolytic effect.
Higher doses can ask for more problems such as endogenous downregulation as well as hypertension and tachycardia..
