I use 23 to draw the b12 from the ampoules then change to 21 to do the injection x

in reply to

I recommend you buy the ampoules snapper from amazon it’s just over three quid ,makes it so much easier to snap then leave container in it to draw up with your syringe good luck x

I have just started IM injections and had spot of blood on thigh after injection. Using blue needle 23G 1 1/4 inch, is this too big?
