A recovery-focused peptide used in healing protocols. Calculate your dose and see the difference between loading and maintenance phases.
Pre-filled with typical tb-500 values. Adjust to match your vial and protocol.
TB-500 is a synthetic version of Thymosin Beta-4 (TB4), a naturally occurring 43-amino-acid peptide found in virtually all human and animal cells. Thymosin Beta-4 plays a critical role in cell differentiation, migration, and tissue repair throughout the body.
TB-500 specifically reproduces the active region of TB4 responsible for actin binding, cell migration, blood vessel formation, and reduction of inflammation. It has been studied extensively in veterinary medicine (particularly in racehorses) and has gained popularity in human performance and recovery applications for its ability to promote systemic healing of muscles, tendons, ligaments, skin, and even cardiac tissue.
Below are common dosing protocols for tb-500 based on available research and community experience:
| Protocol | Dose | Notes |
|---|---|---|
| Loading Phase (Weeks 1-4) | 5-10 mg/week | Split into 2-3 injections; accelerates initial healing |
| Maintenance Phase | 2-5 mg/week | 1-2 injections per week |
| Injury Protocol | 2.5 mg 2x/week | Common moderate dosing for active injuries |
| Typical Duration | 6-12 weeks | Loading 4-6 weeks, then maintenance |

TB-500 comes as a lyophilized (freeze-dried) powder that must be reconstituted with bacteriostatic water before use. The process is standard for all peptides:
For a detailed step-by-step guide with visuals, see our complete peptide reconstitution guide.
Understanding potential side effects helps you use tb-500 more safely. Most side effects are dose-dependent and may improve over time.
Before reconstitution: Store lyophilized (powder) tb-500 in a cool, dry place away from direct sunlight. Refrigeration is ideal for long-term storage of unreconstituted peptides.
After reconstitution: Store the reconstituted vial upright in a refrigerator at 36-46°F (2-8°C). Do not freeze. The solution typically remains stable for 4-6 weeks. Always swab the vial stopper with an alcohol pad before each use.
TB-500 protocols typically follow a two-phase approach. The loading phase (weeks 1-4 or 1-6) uses higher doses (5-10 mg per week, split across 2-3 injections) to rapidly build systemic levels. The maintenance phase then drops to a lower dose (2-5 mg per week, 1-2 injections) to sustain healing.
For example, a common 8-week protocol might look like: Weeks 1-4: 2.5 mg injected Monday and Thursday (5 mg/week total). Weeks 5-8: 2.5 mg injected once per week. Use the calculator above and adjust the dose field for each phase.
