250mg a week isn't TRT....100mg a week does a LOT for health, and WILL make a difference if you were low and need it.
To op, you don't need "liver support" as TRT does not use methylated or other liver stressing compounds. Trt is supposed to be to return or maintain health, and in an otherwise healthy person should not need other stuff. As a point about liver, my brother is on trt and has hepatitis c....no "liver support" needed.
