TB-500 Dosage: Research Protocol and Chart
TB-500 is a synthetic peptide based on a region of thymosin beta-4, studied for cell migration and repair. This guide collects the dosing ranges that appear in research protocols into a clear chart. Figures are research-reported and are not dosing advice.
How TB-500 dosing is structured
TB-500 protocols usually run in two phases. A loading phase uses higher weekly amounts split across doses, followed by a maintenance phase at a lower frequency. Doses are given in milligrams, which is larger than the microgram doses used for peptides like BPC-157.
| Phase | Reported weekly range | Frequency |
|---|---|---|
| Loading (first weeks) | 4 to 10 mg | Split into 2 doses per week |
| Maintenance | 2 to 6 mg | Once weekly or every 2 weeks |
A typical research block runs 4 to 6 weeks of loading, then maintenance. To convert a milligram dose into a syringe volume, use the dosage calculator with your vial size and water amount.
Why the loading phase exists
TB-500 is often described as slower acting than some peptides, so protocols front-load the first weeks to build up presence, then taper to maintenance. The method notes are on the TB-500 protocol page.
Pairing and accuracy
TB-500 is sometimes researched alongside BPC-157 in recovery protocols. Whatever the setup, measure consistently and review the side effect overview before adjusting.
