T2 while Bulking?

Okay, I’m not even going to ask if you can gain muscle and lose fat at the same time…alright? However, I do have a question. I remember Bill Roberts posting that he used a small amount of T3 while in a gaining phase to minimize fat gain. I was wondering if it would be beneficial to use T2 during a such a phase to minimize fat gain and maximize lean mass gains. What are your thoughts? (I thought maybe 1 cap per day would be sufficient)
