Bacteriostatic Water vs TB-500
A side-by-side research comparison of Bacteriostatic Water and TB-500 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Bacteriostatic Water | TB-500 |
|---|---|---|
| Full name | Bacteriostatic Water (0.9% Benzyl Alcohol) | Thymosin Beta-4 (Synthetic) |
| 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. | Upregulates actin production to promote cell migration and proliferation, enhances angiogenesis, and reduces pro-inflammatory cytokines. |
| Molecular weight | Water + benzyl alcohol preservative | 4921 Da |
| Half-life | N/A (solvent) | ~6 hours |
| Bioavailability | N/A (diluent) | ~95% via subcutaneous injection |
| Typical dose | Volume to reach target concentration | 2-5 mg per dose |
| Frequency | As needed to reconstitute | Loading: 2x/week · Maintenance: 1x/week |
| Route | Added to peptide vial for injection | Subcutaneous injection |
