HCG- Best to mix with?

[Flaming Dragon]

Hi guys,

The more I search the more confusing it gets! So here it goes: best solution to mix with HCG for injection: Hospira brand USP

1. Bacteriostatic Water
2. Bacteriostatic Water NaCl .9%
3. Sterile Water
4. Sodium Chloride .09%

Which one would you use to mix with HCG?

Thanks
