So, I recently started GH for the first time. Using 6iu pre-bed.
I had my IGF-1 tested after being on it a few weeks, and my levels are lower than they were before...
Only thing I can think of is that I'm on a cut and have been using 50mg Winstrol/day which can lower IGF-1 via IGFBP.
Anyone seen something like this before? Would really hate for it to be bunk...

Results: While growth hormone increased the IGFBP-3 and IGF-I concentrations, anabolic steroids decreased the same. Concomitant use of growth hormone and anabolic steroids decreased the IGFBP-3 concentration in five out of six abuse periods in spite of the fact that the IGF-I concentration remained elevated in four of them. However, in two men who were on low calorie diet both the IGF-I and IGFBP-3 concentrations decreased during combined GH/anabolic steroid abuse. No proteolytic fragmentation of IGFBP-3 was observed.
