Fill one 100-unit U-100 syringe to about 80 units (0.800 mL).
Weekly research phases
Units and volumes recompute from your Step 1 concentration (2 mL BAC → 2.50 mg/mL · 25.0 mcg/unit).
Standard titration
Secondary educational tables commonly load roughly ~2–5 mg per injection, 2× weekly for several weeks (≈4–10 mg/week), then reduce to lower weekly or less-frequent maintenance. Not an FDA-approved drug.

TB-500 5 mg vials
8 vials
~38 mg mg total peptide over this 12-week schedule at 2 mg → 2.5 mg → 5 mg weekly (phase ladder). Each vial holds 5 mg.
Bacteriostatic water
6 × 3 mL or 2 × 10 mL
2 mL BAC per vial × 8 vials = 16.0 mL total. Buy as 6× 3 mL bottles or 2× 10 mL bottles (whichever you stock).
U-100 insulin syringes (100-unit)
16+ syringes
Some doses need more than one 100-unit syringe at your concentration — plan extras and split draws when the math exceeds the barrel.
Alcohol swabs & sharps
~48 swabs · 1 sharps container
Wipe vial stopper and injection site each time. Dispose needles in a proper sharps container.
Reconstitution steps
- Allow the lyophilized 5 mg TB-500 vial and bacteriostatic water to reach room temperature.
- Draw 2.0 mL bacteriostatic water (default for this guide).
- Inject BAC slowly down the inner wall of the vial — avoid blasting the powder cake.
- Gently swirl or roll until the solution is clear. Do not shake hard (foaming).
- Label with recon date and concentration (e.g. "2.5 mg/mL").
- Refrigerate at 2–8 °C (35–46 °F), protected from light. Prefer using a reconstituted multi-dose vial within ~28 days with sterile technique.
Storage
Lyophilized
Keep dry powder cold and dark when possible (−20 °C / −4 °F preferred for long-term research stock).
Reconstituted
Refrigerate at 2–8 °C (35–46 °F). Avoid freeze–thaw of the working solution. Prefer finishing within ~28 days.
- ·Write recon date and BAC volume on the label.
- ·Protect from light during storage.
- ·Discard if cloudy, particulates, or odd odor appear after reconstitution.
Protocol notes
- ·Often discussed with BPC-157 (see blend guides).
- ·Research use only.
Research context & considerations
TB-500 is a synthetic fragment related to thymosin β4 research on cell migration and tissue repair. Evidence is largely preclinical/anecdotal relative to approved medicines.
- ·Theoretical angiogenesis/cancer-growth caution discussions exist for the class.
- ·Not FDA-approved.
- ·Pregnancy out of scope.
