Is T3 needed with tren a?

[one8nine]

I've planned to use it at 25-50mcg ed to help with a little weight loss, but worry about messing with my thyroid. IYO, is it something to worry about. My cycle is:

Wk 1-12 Test p 50mg ed
Wk 1-10 Tren a 50-75mg ed
Wk 1-12 letro .25mg M,W,F
(Wk 1-10 T3 50mcg ed)

i like it
25mcg or 50mcg is nothing to sweat
if you use 50mcg id taper just a little
week 1- 25cg
week 2-9 50mcg
week 10- 25mcg
