Back in my on/off low dose days I did pills. This time I started on pill which is a PITA with all the other supplements I take. I make a meal out of pill taking. So I went on the patch but with my flabby body what ever the cause, they always fell off and not so good. Injectable was next up and it was fantastic. Like you said once a week or so is all that is needed. Not letting that week slip for too long sometimes is a challenge with my schedule in general because....
Sometimes giving yourself a shot takes a bit of time. It is basically easy and not too painfull for this girl. I've never been bothered at all be needles and such. I'm one of those weirdos that thinks it's cool getting blood drawn. Maybe I spent too much time in hospital as a kid dealing with the early morning vampires?
All it takes for me is one shot that nicks a nerve, doesn't land squarely in a muscle, going way too tense, or whatever that hurts like heck and.... You don't want to ever give yourself a shot again, but you must. There have been times I spent 10 minutes or more working up the nerve.
All of my shots are in my thigh. The problematic ones have been when I ventured too low down in an attempt to avoid the same general area as I alternate legs each week also. I have varicose veins so I also try to choose wisely, which limits my target zones even more. Every now and then I get a squirter upon removal. I can only see what is on the surface. Pretty cool to shoot blood a foot or so away, but no big deal. Usually I don't bruise afterwards, thankfully. I bruise enough as it is without knowing why or when.
