I have been told that bacteriostatic water is better to use than the solution my HCG came with. But how long does the solution last in the fridge once mixed. Do I still need the fridge using bacteriostatic water?
Also I was told to us 19 guage slin pins but every website that sells slins describes them as 29 guage. Was 19 a typo? I think that's a thick pin?
