Your T3 levels are elevated because you are on growth and have a high igf1 level. Your T4 levels will be low unless you are taking T4. The objective is to keep NORMAL NOT HIGH T4 levels while running growth and the dose will depend on your own body… NO ONE CAN GIVE YOU ACCURATE DOSING OF T4 for your body. That will take multiple bloodwork
the main reason you need T4 while you are on growth. You want to get the full effect while on growth and take T4 to keep your T3 levels elevated…. Reason why is while on growth your liver converts t4 to T3 at a very high rate. T3 is a very busy hormone in your body controlling everything from metabolism to heart rate sex drive and a whole bunch of other things.
This is why t3 pills are not needed while on growth if you have a properly working thyroid. Your thyroid will be working in overtime trying to keep up with the T4 production your body is needing because it is sensing the high conversion rate that’s going on in the body.
So taking T4 will help your thyroid out and cause less stress. As your thyroid creates very little T3. Most of your T3 is made through the conversion of T4 to T3 in your liver and some in your kidneys. Another reason you need to take supplements for those while on growth.

@mands suggested I stop taking T4 while I was running my hgh weekly tests a while back to see if my T4 level leveled out to normal again…. It did but after 3 weeks dropped low again. So your body of working correctly will try its hardest to level out your hormones but in my body it did drop low again. So I’m concluding that I always run T4 while on growth and my dose changes depending on how many iu’s of growth I am doing.
your body is a machine and if you have EVERY organ working in range that need to be in range minimal gear is needed to achieve a great result with less stress on the human body.
