Bacteriostatic Water (Bac Water) is an essential solution for all researchers. It's sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth, making it perfect for reconstitution.
 
Hospira brand bacteriostatic was is considered the "Gold Standard" for Bac water among the research community. 
 
Most peptides come as a lyophilized powder (puck) and will require Bacteriostatic Water for reconstitution.  Please refer to our Peptide Calculator to help with your reconstitution research needs.
