Do you use the autoinject or just do the shot manually?
I am on Beta and found that the autoinject left the worst marks. I inject manually now and hardly have any site reactions. The key (for me) is to go s-l-o-w. I use my tummy and saddlebag area almost exclusively since they are not seen by anyone and even if there was a site reaction it wouldn't be noticeable to anyone but me.
I can't inject into my arms very well because my right hand is numb and I can't control the syringe well with my left hand.
Good luck with your shots. Ain't it fun!
