So I am really thinking about running HGH. But getting all my knowledge in place before doing so. That being said. I am on t4 already at 112 mcg a day because of thyoid issues. I have been on for 8 years. If running HGH should I up the t4? Or keep it the same? I will be getting baseline blood work for EVERYTHING before running any HGH. Because doing baseline bloods before running any Test was the best thing I could of done. Edit 112 mcg keeps me right in the middle of where the range is.
