sure, anecdotal evidence. lots of guys have been known to lose muscle mass when taking large doses of T3 prepping and dieting for a show,, but these same fools are also taking a shit ton of AIs and trying to crash their estrogen.. thats why they lose muscle. its not the T3 itself.
females generally do very well with T3 and don't lose muscle or become catabolic because they have naturally higher estrogen levels.
estrogen is the key to muscle preservation
