Phosphate Buffered Saline vs TB-500
A side-by-side research comparison of Phosphate Buffered Saline and TB-500 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Phosphate Buffered Saline | TB-500 |
|---|---|---|
| Full name | Phosphate Buffered Saline (PBS) | Thymosin Beta-4 (Synthetic) |
| Category | Healing & Recovery | Healing & Recovery |
| Status | Buffer solvent | Research compound |
| Mechanism | The phosphate buffer maintains a stable, near-physiological pH (~7.4) while the saline provides isotonic conditions, protecting peptides and proteins from pH-driven degradation during dissolution and handling. | Upregulates actin production to promote cell migration and proliferation, enhances angiogenesis, and reduces pro-inflammatory cytokines. |
| Molecular weight | Buffered salt solution | 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/protein vial | Subcutaneous injection |
