I have injected hgh 18 times so far, 2 times per day, 5 days per week. But now, I found that there are some lumps underneath my belly where the place I injected. The lumps are a bit stiff, just like a little ball. I changed places every time I injected. Does anyone have the same experience? Please share your thoughts and experience. I am quite scared now. Thank you very much for answering.
