Bacteriostatic Water (BAC) • Ultra-Pure Reconstitution Solvent

Bacteriostatic Water for Injection is a sterile, non-pyrogenic (fever-inducing-free) preparation of ultra-pure water containing 0.9% benzyl alcohol ($C_7H_8O$) added as an antimicrobial preservative. It is the definitive industry standard for the reconstitution, stabilization, and long-term storage of lyophilized (freeze-dried) research peptides.

Mechanics of Action & Stabilization

Peptides in their lyophilized powder state are highly fragile and vulnerable to rapid degradation upon introduction to ambient moisture or micro-organisms. Bacteriostatic Water preserves sample integrity through two critical factors:

• Antimicrobial Invalidation: The addition of 0.9% benzyl alcohol acts as a bacteriostat, effectively suppressing, inhibiting, and halting the growth of any potential bacterial contamination introduced during multiple needle punctures.

• Extended Storage Window: Unlike standard Sterile Water (which must be discarded after a single use), a vial of Bacteriostatic Water allows reconstituted peptide solutions to remain stable, sterile, and viable for repeated aspirations over a 28-day window when properly refrigerated.

Key Reconstitution Properties

The Quality Foundation: High-end research depends entirely on the purity of your solvent. Using non-stabilized water can lead to rapid enzymatic breakdown of your peptides (like Retatrutide or MOTS-c), invalidating study metrics.

• Optimal pH Range: Buffered to a precise pH range of approximately 4.5–7.0, preventing acid- or alkaline-induced peptide cleavage during the critical mixing phase.

• Multi-Vial Compatibility: Specifically engineered to safely dissolve complex, heavy peptide molecular structures without disrupting delicate disulfide bonds or secondary peptide folds.

• Long Shelf Life: Unopened vials maintain absolute sterility and chemical stability for up to 18–24 months when stored under optimal conditions.
