So - I found it on AR-R.com.. I am looking to order it but had a few questions. I am sure I could google this, but I will likely end up more confused than I am already! It looks like there are multiple buying options - some with "Bacteriostatic Water 30mL" and others "NaCl - Sodium Chloride 0.9% 30mL".. What does that mean?

From what I have read, its an inject-able, so is that to dilute it? Or perhaps make it enter the blood stream?

Back to google I guess - but if anyone wants to break it down for me, I sure would appreciate it!
