Bacteriostatic Water 30mL
0.9% benzyl alcohol bacteriostatic water — the required reconstitution solvent for all lyophilized research peptides in the Clavicular Stack. 10ml multi-use vial.
Bacteriostatic Preservation for Multi-Use Peptide Reconstitution
Bacteriostatic water (BAC water) is sterile water for injection containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth following needle puncture by disrupting bacterial cell membrane integrity and membrane-associated enzyme systems — allowing safe multiple draws from a single vial for up to 28 days when stored at 2–8°C. At 0.9% concentration, this bacteriostatic action occurs without causing peptide denaturation or precipitation — critical for preserving all GLP-1 analogs, BPC-157, TB-500, CJC-1295/Ipamorelin, NAD+, GHK-Cu, SNAP-8, and Epithalon across multi-day research protocols. Regular sterile water has no preservative and is considered single-use only after puncture. pH adjusted to 5.0–7.0, within the stability range of all research peptides.
Research Highlights
Required for Every Peptide in This Catalog
Every lyophilized research peptide in the Clavicular Stack — Retatrutide, Semaglutide, Tirzepatide, CagriSema, CJC-1295/Ipamorelin, BPC-157, NAD+, GHK-Cu, TB-500, SNAP-8, Epithalon, IGF-1 LR3 — requires reconstitution with bacteriostatic water before use. One 10mL vial typically covers 2–4 reconstitutions.
28-Day Multi-Draw Sterility
The 0.9% benzyl alcohol preservative inhibits bacterial growth following needle puncture, allowing multiple draws over 28 days when stored refrigerated. Without this preservative, each reconstituted vial would be single-use only — impractical for any multi-day or multi-week research protocol.
Peptide Compatibility
Benzyl alcohol at 0.9% is compatible with all standard research peptides including GLP-1 analogs, structural peptides, small tetrapeptides, and copper complexes. pH 5.0–7.0 is within the physiological stability range for all listed compounds.
