I wonder if I need to supplement T4 when I am using AAS cycle with HGH. HGH is suppressive to TSH and this causes a low level of thyroid hormones. Fat burning effect from HGH is attributed to thyroid hormones but HGH is suppressive to T3? addition of T3 is not advisable when using HGH? Should I use T4 instead? how much of T4 to use?
