Yah thats some crap. I would say its the cream at this time since the other guys all had issues with defy/empower cream. I would call empower and tell them their cream is not working like the other batches and you want them to fix it.
If your t3 is this low on thyroid meds I would first suspect you took labs at a different time after dose. T3 half life is short and this shows you probably should be taking it more often if t3 drops that much a few hours after dose. Perfect example why I always tell guys to dose it 3 times a day. I take my 2 grain tablet of armor thyroid twice a day.
