i've done about 10 injections so far of sus and deca. the deca doesnt phase me, but the sus is a real killer at times. i've tried different areas and different guages (delts 23 & 25 1 inch and glutes 23 & 25 1 1/2 inches). majority of time it will be a bit sore for a couple of days and other times it feels like i've been hit with a bat. is this the deal with sus or did i hit a muscle or something?
