Would it be possible to create your own injection ampoules? Well I know it would be possible but I suppose my real question is about what the risks and dangers would be. If you kept everything sterile and made sure you used very clean substances what exactly would the risks be, if you filtered the solution with a micron filter would that make a difference? I've tried searching everywhere but can't find any information anywhere. Having a fridge full of ampoules of various substances would be pretty sweet.
