I have always used 25 gauge needles which took some time to inject since it was so thin, Usually about 30 seconds for 1.5 cc's. Well, tonight I decided to switch to 23 guage needles to make it easier for my wife.
Well, it was real easy for her to do. It only took like 15 seconds 1.5 cc's. I told her to go slow, but.... So what should I expect from it injecting so fast? More soreness? Any other drawbacks?
