I actually have. I also tested mine before using any GH use (baseline). If I have time I can dig up the actual numbers but the IGF basically was around 130 baseline, around 240 with the 10IU GH serum test and at 6 weeks it was around 350. My GH baseline was <.02 (I think) and with the GH serum test it was in the 40s.
This was the first time I ever tested at the six week mark because I heard S2H on the PED podcast mention that it takes that long to peak. Also, this was the only time I was over 300. I was using Hyges for this test and still use them.
