Hey Rusty…just saw this. Regarding T3, there is a feedback loop between T4 and T3. So maybe looking at supplements that influence T4 production can bring you back into balance. Also, I have had read research that using large doses of gear, over 200 mg per day, impacts that loop. Since your body can only utilize, I’ve read only 125 mg of testosterone or it’s derivatives but I think that is extremely conservative, a certain amount of hormones the amount that can’t be utilized is stored in fat cells. This in turn directly impacts the T3/T4 conversions. Something to think about. I’ll look into T4 regulation and see if there is a supplement that can push you along.
