Using T4 along with HGH as Anthony Roberts Suggests

I am now using T4 along with my HGH and am wondering how long you can safely run the T4. If I plan on running the HGH indefinitely, I surely could not do that with the T4 I would think. Ive seen dosing pyramids for using T3, something in the neighborhood of 60 days, but cant seem to find anything on T4. Looking for some help here.

I got T4 from AG-guys
