It doesn't matter, it does not caused localized growth, but causes localized adipose tissue catabolization. Therefore inject where there is fat !! GH goes into the blood and the liver converts is to IGF-1 among other things, but the IGF-1 causes growth. It's no longer in the gut, it's in the blood stream so receptors can pick it up, point is, and should never be forgotten is that the intestines and other organs in that area are much denser in receptors than muscle tissue is. Therefore GH gut is always a risk NO MATTER where you inject it. I would never take it any other way than sub-q in the gut and started that over a year ago. Took pics every 2 weeks and could see a noticeable difference, and NO, no gh gut yet.
