hmm, marks arnt an issue for me. my needs are usually SUPER tiny, like to the point where the test is too thick to be drawn up unless i hold it at the right angle and then its a very slow process lol. i switched to them after having needle marks all over my ass from the larger needles, but these i dont even feel at all, which is nice.
just curious, when injecting into the glutes, theres nothing u can hit, correct? i cant remember which side it is, but when i use my left hand (im right handed) it usually bleeds a little bit and when i use my right hand to inject into my left side it doesnt usually bleed. i used to always freak out i was gona hit something, but can u?
