BAC water, often referred to as antibacterial water, is specially treated water designed to be free of microbial contaminants, and it plays a critical role when handling lyophilized peptides. Lyophilized peptides, which are peptides in a freeze-dried form, are extremely sensitive to contamination. Even minor impurities in the water used for reconstitution—like bacteria, fungi, or other pathogens—can compromise the peptide’s integrity, stability, and safety. Thus, using antibacterial water is a foundational step in ensuring that the peptides remain pure, effective, and free from risk of infection.
