Bacteriostatic Water vs BPC-157 (Oral)
A side-by-side research comparison of Bacteriostatic Water and BPC-157 (Oral) across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Bacteriostatic Water | BPC-157 (Oral) |
|---|---|---|
| Full name | Bacteriostatic Water (0.9% Benzyl Alcohol) | BPC-157 Oral Formulation (Arginate Salt) |
| 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. | Same mechanism as injectable BPC-157 but delivered orally. Upregulates VEGF, modulates NO system, and promotes gut mucosal healing through direct contact and systemic absorption. |
| Molecular weight | Water + benzyl alcohol preservative | 1419.53 Da |
| Half-life | N/A (solvent) | ~4 hours (oral bioavailability lower but sustained) |
| Bioavailability | N/A (diluent) | ~40-60% oral (arginate salt form) |
| Typical dose | Volume to reach target concentration | 500 mcg - 1 mg |
| Frequency | As needed to reconstitute | 1-2x daily |
| Route | Added to peptide vial for injection | Oral capsule (arginate salt) |
