are there slin pins with removable needles?

[vestax]

I have to stick my slin pin in a bottle of B12, then a bottle of IGF and so the needle gets pretty dull and is uncomfortable going into the skin. what can i do to stop this?

i loaded it in a different pin yesterday and shot it and it was like a joke i didnt even know i stuck myself- but that mixes the igf + b12 together

Where abouts are you location wise? Here in the UK we have 1ml slin pins that you can change the pin on.

get 31gauge, doesnt matter how dull it is goes in easy. If you can't handle that then I don't know what to say.
