OK so this is my 3rd cycle and have usually used glutes for the most part as the past cycles have just been test e every 3.5 days. Moved on to using quads and delts lately as I added tren this cycle but did a glute shot yesterday and notice today I have a small lump under the skin. It's not hot, swollen or red just iches a bit and thats what made me notice. Anything to be concerned about and what causes this?
