My doc has written me 90mcg's of t-4 a day for seven weeks. I am taking 2iu's of HGH 5/2 along with 200 mg's of test e and deca. I am not just taking the t-4 for fun. My thyroid is vey slow and could use a boost. I feel tired all the time and could not figure out why.... The doc at the Hrt called and said my thyroid was below normal....and thats why I was tired. I orginally thought it was due to low test@!! I've read that you should take at least 100mcg's aday because it converts to a 4/1 ratio to the t-3?? This will be my first time on thyroid meds and I am pretty scared that I will fu#k myself up. Even though all the research ive done here tells me no worries![]()
