Reconstitution
10 mg TB-500 vial in 2 mL bacteriostatic water
Reconstituted at 10 mg / 2 mL, the vial holds 5 mg/mL. On a U-100 syringe, 50 units = 0.5 mL = 2.5 mg; 100 units = 1 mL = 5 mg. TB-500 uses larger, less frequent doses than the daily peptides.
The TB-500 dosage chart covers reconstitution of a 10 mg vial and the weekly loading and maintenance protocols below, with the exact unit math for each dose. TB-500 is a systemic repair peptide with a long half-life, so it is dosed weekly rather than daily.
Dosage protocols
Loading
2.5 mg twice weekly (≈5 mg/week) is the common loading dose. Because TB-500 has a ~14-day half-life, twice-weekly dosing maintains steady levels without daily injections.
Maintenance
After loading, 2.5 mg once weekly maintains levels. The long half-life means the compound accumulates — space doses and cycle rather than dosing daily.

From vial to injection
- Sanitize Wipe the TB-500 vial stopper and the bacteriostatic-water stopper with fresh alcohol swabs and let them dry.
- Draw the diluent Draw 2 mL of bacteriostatic water into a reconstitution syringe.
- Add water slowly Angle the needle so the water runs down the inside wall of the vial rather than onto the powder.
- Swirl, don't shake Gently swirl until fully dissolved. Never shake.
- Draw your dose With a U-100 insulin syringe, draw to 50 units (0.5 mL = 2.5 mg). A full 5 mg dose is 100 units (1 mL).
- Inject subcutaneously TB-500 is systemic — inject subcutaneously anywhere (abdomen or flank), not site-specific like BPC-157. Store reconstituted vial at 2–8 °C, use within 28 days.
Feeling something? Check here
- Mild, transient injection-site redness or a small welt that fades within an hour
- Brief head-rush or fatigue after a loading dose
- Persistent lethargy or headache during loading — extend the interval between doses
- Injection-site lumps or bruising lasting more than a day — rotate sites, check technique
- Facial/throat swelling, difficulty breathing, hives — stop and seek emergency care
- Signs of injection-site infection — spreading redness, heat, pus, fever
- Any new or growing lump elsewhere — growth/repair peptides are contraindicated with active or suspected cancer
Anchored to a phase-1 thymosin β4 trial (54 healthy volunteers, 0.05–25 mcg/kg IV) that reported mild-to-moderate adverse events with no dose-limiting toxicity.
