The research form of thymosin β-4 — wound healing, blood-vessel formation and tissue remodelling.
Accelerated soft-tissue healing (tendons, ligaments, muscles); reduced inflammation and joint pain; improved flexibility and range of motion; faster recovery between workouts.
The clearest case of trial data belonging to a different molecule. All human trials (RegeneRx) used FULL-LENGTH thymosin beta-4 by IV or eye drop. TB-500 is a synthetic fragment, injected subcutaneously, with zero human dose-ranging trials of its own.
An average dose looks like:
10 mg vial + 2 mL water = 5,000 mcg/mL
1 mg → 0.20 mL · 20 units
That figure is one person’s at that exact reconstitution — not a community average, not a clinical dose. A different vial size or water volume changes the draw entirely.
| TB-500 | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 10 mg vial | 10,000 mcg/mL | 5,000 mcg/mL | 3,333 mcg/mL | 2,000 mcg/mL |
| One unit (0.01 mL) | 100 mcg | 50 mcg | 33 mcg | 20 mcg |
Concentration = vial contents ÷ water added. It is the same compound at every volume — more water only means a weaker solution, larger syringe marks that are easier to read, and a larger injection volume. On a standard U-100 insulin syringe, one unit is 0.01 mL at any barrel size.
Education only. This page is educational. Most compounds referenced are not approved for human use, and a "research use only" label carries no legal status of its own.
Reported, not established. Any figure shown is a reported personal reference at the reconstitution stated — not a community average, not a clinical dose, and not necessarily right for anyone else's body, goals, or product.
Blank is deliberate. Where no figure appears, there is no personal reference to give. We would rather say nothing than imply confidence that isn't there.
Not medical advice. Nothing here constitutes medical advice, diagnosis, or treatment. Several of these are prescription medicines in Canada and the US, and several are approved nowhere at all. Consult a qualified healthcare professional before beginning any protocol.
