5th dose - Syringe and needle supplier

So I’m wanting get insulin syringes with needles to take the 5th dose. I’ve tried twisting and it’s just not giving me an accurate enough tell on how much I’m actually getting and now I’m at 7.5 I really don’t want to be taking too much more than I should be. Twisting works but I find it’s hard to know how much is coming out. At this stage I don’t want to waste any if I can manage it.

Anyone link me to syringes they’ve used successfully? Amazon would be great but not necessary.
