I started on Humatrope 72 IU cartridge at 2.5 IU a day five weeks ago. During that week I had a pre-arranged Blood test for my TRT, so I asked them to do an IGF-1 test as well just to make sure I was getting something close to real HGH. I got the results back today and it came back at 421 vs. 160 when I did it a couple months ago. Should it have been that high after only 5 days on? I pinned it and had my blood drawn a couple hours later. Another interesting note was my blood glucose that was very high my previous 3 tests and considered pre diabetic came back perfect. Not sure what to think.
