Hey guys, I've been on HGH for about 7 weeks now, at 4iu/day for the last 5 weeks. The last month I've been pretty lethargic. I started T4's about a week ago at 100mcgs./day. What I was wondering is how long will this lethargy last? It's really hard to get up in the morning. Also, other than fat loss, what differences do you notice with theT4 and in what sort of time frame? Thanks.
