Bacteriostatic Water vs LL-37
A side-by-side research comparison of Bacteriostatic Water and LL-37 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Bacteriostatic Water | LL-37 |
|---|---|---|
| Full name | Bacteriostatic Water (0.9% Benzyl Alcohol) | Cathelicidin Antimicrobial Peptide LL-37 |
| Category | Healing & Recovery | Healing & Recovery |
| Status | Reconstitution solvent | Research compound |
| Mechanism | The benzyl alcohol acts as a bacteriostatic preservative, inhibiting bacterial growth so the vial can be entered multiple times over about 28 days. It dissolves lyophilized peptide powder into an injectable solution. | Disrupts microbial membranes, neutralizes endotoxins, recruits immune cells via chemotaxis, and promotes angiogenesis and re-epithelialization. |
| Molecular weight | Water + benzyl alcohol preservative | 4493.33 Da |
| Half-life | N/A (solvent) | ~4-6 hours |
| Bioavailability | N/A (diluent) | Variable by route; topical and injectable |
| Typical dose | Volume to reach target concentration | 50-100 mcg |
| Frequency | As needed to reconstitute | Daily |
| Route | Added to peptide vial for injection | Topical or subcutaneous injection |
