Well I have hypothyroidism confirmed by blood tests right now I'm on 50mcg t4 and 150mgs of test a week(prescribed) since I have hypo I'm going to implement 25mcgs of t3 in before a workout and dose the t4 in the morning before a meal- I'm not concerned with catabolism as my thyroid needs it- does this make sense? Catabolism should not occur if I'm hypo correct?
