I finished up my first 7day run on T3 and I am off for the next 5 days. My question is...Should I lower my calories during my PCT days to accomodate for the reduced Thyroid production. Or is my thyroid still holding some of the synthetic T3 (I am not sure of the active-life of T3) and I don't have to worry about any rebound in the time between cycles?

I hadn't even though about this before I started. Things seem to be going great so far.
