What is TB-500?
TB-500 is a synthetic peptide fragment corresponding to the active region of thymosin beta-4, a naturally occurring protein involved in tissue repair, cell migration and regeneration pathways.
In research discussions, TB-500 is most commonly associated with tissue repair, wound healing, angiogenesis, collagen deposition, inflammation pathways and recovery-related animal studies.
TB-500 Reconstitution Example
The example below is based on a common 10mg TB-500 vial mixed with 3.0mL bacteriostatic water.
Reconstitution Maths
10mg ÷ 3.0mL = 3.33mg/mL
3.33mg/mL = 3,333mcg/mL
1 unit on a U-100 syringe = 0.01mL
3,333mcg/mL × 0.01mL = approximately 33.3mcg per unit

Standard Gradual Research Example
This example uses a 10mg vial reconstituted with 3.0mL bacteriostatic water, giving a concentration of approximately 3.33mg/mL.
Frequency and Timing Notes
TB-500 is commonly discussed as a once-daily subcutaneous compound in the source protocol. The example gradually increases from 500mcg daily toward 1,000mcg daily.
Timing is usually flexible. The key practical point is consistency, site rotation and careful tracking of the amount used, injection site and observations.
Reconstitution Steps
- Confirm the vial size before calculating concentration.
- Draw 3.0mL bacteriostatic water using sterile technique.
- Inject the bacteriostatic water slowly down the inside wall of the vial.
- Avoid blasting the powder directly and avoid creating foam.
- Gently swirl or roll the vial until dissolved.
- Do not shake.
- Label the vial with the reconstitution date and concentration.
- Store refrigerated at 2-8°C, protected from light.

- Frequency: once daily in the source protocol.
- Timing: any consistent time of day is commonly discussed.
How TB-500 Works
TB-500 represents the active N-terminal fragment of thymosin beta-4. The source protocol identifies the heptapeptide sequence as Ac-LKKTETQ.
This region is discussed for actin-binding and cell-migration properties. Preclinical research commonly links TB-500 and thymosin beta-4 fragments with angiogenesis, wound healing, cell motility and tissue regeneration pathways.
The source also notes research suggesting TB-500 may act as a prodrug, cleaving to an active pentapeptide metabolite that may drive biological activity.

- Prohibited in competitive sports under WADA rules
- Not a guaranteed treatment for injury, inflammation, wound healing or tissue repair
Storage Instructions
- Lyophilised powder: store frozen at around -20°C in dry, dark conditions.
- After reconstitution: refrigerate at 2-8°C.
- Use window: commonly discussed as within 28 days when mixed with bacteriostatic water.
- Do not freeze after mixing: freezing reconstituted solution may damage peptide integrity.
- Protect from light: keep the vial away from unnecessary light exposure.
- Avoid: heat, sunlight, moisture, contamination and repeated freeze-thaw cycles.
- Practical note: allow vials to reach room temperature before opening to reduce condensation uptake.
Injection Technique Notes
This section is general educational information only. It is not personal injection instruction.
- Use a new sterile insulin syringe for each administration.
- Clean the vial stopper and injection site with alcohol and allow both to dry completely.
- Common subcutaneous sites discussed include abdomen, thighs and upper arms.
- Rotate injection sites systematically to reduce local irritation and lipohypertrophy risk.
- Pinch a skinfold and insert into subcutaneous tissue at an appropriate angle.
- Do not aspirate for subcutaneous injections.
- Inject slowly and steadily.
- Wait 5-10 seconds before withdrawing the needle to help reduce leakage.
- Withdraw the needle at the same angle and apply gentle pressure if needed.
- Do not rub the site vigorously.
- Dispose of used sharps safely in a sharps container.
Lifestyle Factors That May Matter
- Protein intake: adequate protein supports normal tissue repair and recovery processes.
- Training load: avoid overtraining during injury recovery research contexts.
- Physical activity: appropriate movement and rehab-style activity may support recovery goals.
- Sleep: 7-9 hours of quality sleep supports natural repair mechanisms.
- Stress management: chronic stress may interfere with recovery and inflammation balance.
- Tracking: documenting amount, date, site and observations can make tolerance patterns easier to review.
