t4 really needed with t3?

[needmoney4mtren]

I started taking 20 mcg of t3 daily and was wondering if it was actually necessary to run t4 along side it.

I’m taking 20 IUs of HGH so i know my t4 -> t3 conversion is supified but why is supplementing t4 necessary?

I’m also on 200mg of tren so I’m assuming that it lowered my t3.

Can someone explain to me if its a no brainer to take t4 or if its not going to fuck anything up by not taking it.

T3 3 X 25mcg/day
T4 100mcg/day

T3 3 X 25mcg/day
T4 100mcg/day

i know about the 1:4 ratio i just dont get why i need t4. I also dont have a source for t4 only t3.
