I just did the same 3iu I did every morning before test. I pinned about an 1hour before test. I had been doing about 3iu’s per day for about a month. I chose to do it that way so I can see what my igf1, t3, and t4 would be on my normal routine. I had already taken bloods to check Genoxon hgh performance before but this time I wanted to know what my thyroid was doing will on hgh because I was contemplating adding T4 to my regimen. My thyroid was able to handle 3ius daily. So I’m going to step it up to 4iu and see after retest again.
