So I've been on hgh for about a year and a half. I've been on 5i.u. for about 9 months with no problems. I've recently been diagnosed with carpel tunnel in both hands. I'm only 30 years old. Anyone experience something similar? Do you think the hgh is the cause? Should I come off and if so will it subside? I read that my t3 my be depleted? Any help or suggestions would be appreciated.
