An actual clinical trial of hGH (human growth hormone) was conducted and published here. The trial shows that patients with low IGF-I (the blood factor that we follow for growth hormone) and fibromyalgia saw improvement in their fibromyalgia pain with regular dosing of hGH. This shouldn’t come as a surprise since hGH and IGF-I both are involved in various enzyme cascades including those associated with inflammation. Also, for someone with low levels of hGH to do better when supplemented isn’t a surprise either.
