Refillable injector pen

[tweek]

Can you fill the cartridges up only part way, its optimal for my dosing to only have 1.8ml inside the cartridge, will this lead to injecting air or how do i prevent this/is this okay?

You'll be fine man.
Before injecting just bleed the air out until you get some of the fluid come out.

You'll see that little rubber stopper keep moving up the cartridge and pushing all the air out

It should. I probably won't use the 3ml carts that it comes with tho.

I personally don't like that style, but it should work with normal cartridges and needles.
