So you weigh about 123 lbs.? It will have to be the abdominal area. That is all I know. I would guess 1 ml or re-read the article from the inject site concerning the patient.
I do not know about the needles..look for sub q and testimonials/reviews of the best and sterile pkged ones. Don't get any that are not sterile. and do not touch the needle at all with a cotton ball and even with alcohol too.
I just remember reading that.
