TB-500 Calculator
Also known as: Thymosin Beta-4, Tβ4
What is TB-500?
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring 43-amino-acid actin-sequestering peptide. Veterinary use in racehorses is well documented; human research is limited. Common protocols use a loading phase of 2–5 mg twice weekly for 4–6 weeks followed by a 2 mg weekly maintenance phase. It is frequently stacked with BPC-157.
| 2 mg | lyophilized powder |
| 5 mg | lyophilized powder |
| 10 mg | lyophilized powder |
| 0.5 mg | ≈ 25 U-100 units (at 5mg / 2.5mL) |
| 1 mg | ≈ 50 U-100 units (at 5mg / 2.5mL) |
| 2 mg | ≈ 100 U-100 units (at 5mg / 2.5mL) |
| 2.5 mg | ≈ 125 U-100 units (at 5mg / 2.5mL) |
| 5 mg | ≈ 250 U-100 units (at 5mg / 2.5mL) |
How it's typically prepared
Reconstitute with bacteriostatic water and refrigerate. The peptide is generally stable for 4–8 weeks at 2–8 °C.
Frequently asked questions
- What is the 'Wolverine stack'?
- An informal name for combining BPC-157 with TB-500 for connective-tissue support. Both peptides are reconstituted separately and either drawn into a single syringe at the time of injection or alternated between sites.
- Is TB-500 the same as Thymosin Beta-4?
- TB-500 is an active fragment of Thymosin Beta-4 — closely related but not identical. Compounding pharmacies sometimes use the names interchangeably; check your specific product.
