That's a good question. I always ran 100 mcgs of t4 while running hgh which I believe converts to 25 mcgs of t3. I always did well just doing that along with a tes/tren cut cycle.
Well bb , I'm on hgh for anti aging purposes and on the same t4 dosage u are using , but I ve seen some different opinions about using t3 and t4 together.
I agree with you that t4 converts to t3 , so this means that using both is useless?
