sure it would help.. ive been up to 150mcg and ddnt lose an ounce of muscle.. flat as hell tho on a daily basis.
this, high doses make you look like absolute shit and completely flat. youll look like a soccer player since you wont EVER feel full muscles or even any pump anymore. fat loss is not THAT faster with high doses though (unless you really abuse).
i love running t3 at 50mcg year round... you only get the positives at that dosages, puts you into a state of mild hyperthyroidism, if youre an endomorph naturally it really helps with staying lean. i also believe up to a certain dosage t3 can actually amplify gains when in a good dose of AAS (since it increases protein turnover, so both synthesis and breakdown).
