I did a left glute injection 1 ml of androphen last Wednesday. 8 days ago. I used a 1" 25g. I did the right glute on my first injection with no issues. This was the first injection into this left glute. I noticed that there is a lump inside now. Doesn't hurt but I'm not sure if this is normal. Should I go to a 1.5" needle for my Glutes? I rotate multiple injection sites.
