Reconstitution Water Peptides

Reconstitution Water for Peptide Research

Reconstitution water is essential for dissolving lyophilized peptides before use. We offer two options: Bacteriostatic Water (BAC), the standard for multi-use peptide reconstitution, and GAC Water (Glycerin-Acetic Acid), a specialized solvent for peptides that require acidic pH or enhanced solubility. Choosing the right water type is critical for maintaining peptide stability and bioactivity.

Key Points

BAC Water contains 0.9% benzyl alcohol as a preservative - safe for multi-dose vials over 28 days
GAC Water is recommended for GH-releasing peptides and peptides requiring acidic pH for stability
Both available in 3ml and 10ml vials to match your peptide vial sizes

BAC Water vs GAC Water

Property	BAC Water	GAC Water
Composition	Sterile water + 0.9% benzyl alcohol	Sterile water + glycerin + acetic acid
pH	Neutral (~7.0)	Acidic (~3.5-4.5)
Best For	Most peptides (BPC-157, TB-500, Semaglutide, etc.)	GH secretagogues, peptides requiring acidic pH
Multi-Dose	Yes - benzyl alcohol prevents contamination	Yes - acidic pH inhibits bacterial growth
Sizes	3ml vials, 10ml vials	3ml vials, 10ml vials
