I have a question. My last 2 shots of hgh has left a lump one bigger then the other. Not sure if it's cause my toolbelt was rubbing against it that irritated it or was a bad shot . It feels itchy and a little swollen almost like pip . I do my shots in my stomach I've done many successful shot but the last 2 not so much . I always sterilize my area and very careful. Im wondering if this is normal? Have others had this issue? Did I go to much on a angle ? So its under my skin ? Should I go more of a 90 degree angle instead of a 40 . Hoping some vets can shine some light . Its almost like pip but more itchy.. I use 5/16ths by the way..
