I use 22gg @ 1' 1/2. I alterante from left to right glute during my 12 week cycle. For the first time in my short - time using steroids (about 1 year), i have a tiny bump/scar now. I think its a small build up of scar tissue, but how can i avoid more of these blemishes? Did i push in too fast? Should i find another place to rotate, ie thigh, shoulder? Any one who has an idea how I can avoid further blemishes would be much appreciated.
