reconstituting peptides bacteriostatic Vs. sterile water

I know bacteriostatic water is better about destroying prions or impurity whilst sterile one doesn't, suppose.
But sterile water does contain no alcohol so it does not affect peptides chemical structure.
If I used bacteriostatic one I fear its own alcohol could damage or alter the peptide chemical strunctures.
On the other hand if I used sterile one I fear it cannot destroy prions or impurity, etc.
So which one is the best to reconstitude peptides?
 
I think best is going to be opinions, if that's what your looking for then so be it. It's like test e and test c which is better.... And the debate goes on
 
Yes it's right.
Let's talk about bac water only.
For example let me know between Hospira Bacteriostatic Water 30 mL plastic vial Vs. APP PHARMACEUTICALS Bacteriostatic Water 30 ML glass vial.
I had read that Hospira's one contains 0.9% (9 mg/mL) of benzyl alcohol added as a bacteriostatic preservative
Whilst the APP PHARMACEUTICALS Bacteriostatic Water contains 0.12% methylparaben, 0.012% propylparaben added as a bacteriostatic preservative. pH 4.5 to 7.0.
I wouldn't want get to damage peptide own chemical struncture by methylparaben or propylparaben ,so I get the feeling Hospira's one is more suitable, don't know.
Which one would be more suitable to reconstitute peptides and which one you all use? Thanks
 
Pretty much every How To video on You Tube shows bac water. The amount of preservative is very low and is also very likely present in an amount that won't damage meds since that is what it is made for.

Thank you so much guys.
BTW is it wise using sterile water? Is there no possibility to get prions or bacteria? I see the purity grade of peptides is never 199% but 97-8 or something like this. So maybe reconmstituting peps by sterile water is not very wise IMHO
Sterile water can not destroy prions or bacteria.
