Yeah, with low dose T4 only, but once you add T3 to T4, they have a synergistic effect on dropping TSH.
Thing is, when you take T4 only, your Free T4 can go up but your Free T3 can go down. T4 only usually leads to higher T4 to T3 ratio unless you use HGH. We all have different genetics affecting our rate of conversion, our sensitivity to TSH dropping, and even lifestyle will affect T3 conversion (low cals/low carbs/lots of cardio/being leaner = lower T3)
Taking thyroid hormones to boost metabolism kind of sucks for physique/performance purposes; it can make you flatter, increase hunger, lower endurance/strength etc. Many pros just run HGH+extra T4 and they don't touch T3.

@Beef_Stu_97 has a recent Q & A thread and he runs 100-200 mcg T4 year round + HGH. Zero T3.
It's best to optimize the thyroid if you're hypothyroid, otherwise, year round HGH works much better for getting and staying lean and it keeps you full too.
