TB-500 10-vial kit
from €289
Synthetic piece of thymosin β4 · kits of 10 or 30 vials
Thymosin β4 fragment, synthetic
TB-500 is a short synthetic piece of thymosin β4, a natural peptide that controls actin and cell movement. Recovery and tissue-repair studies use it widely.
Research use only: laboratory and in-vitro work. Not for use in people or animals, and not for diagnostics.

On requestTB-500 copies the active region of thymosin β4. That natural peptide helps regulate actin and the way cells migrate. Tissue-repair studies often run it alongside BPC-157.
TB-500 comes in sealed kits of 10 or 30 freeze-dried vials. Certificates from an independent third-party laboratory are published per batch on /certificates as they become available. For laboratory and in-vitro research only.
TB-500 reproduces the part of thymosin β4 that binds actin. Thymosin β4 itself is a small natural peptide. In most cells, thymosin β4 is the main protein that holds G-actin. It keeps single actin units in reserve and decides how many are free to build filaments.
Cells need actin filaments to move. So papers test this fragment in models of wound closure, new vessel growth and cell motility. It acts through the cytoskeleton, not through a classic receptor.
A short summary of published work, given as research context. It makes no therapeutic claim.
Cardioprotection work is reviewed in a 2016 chapter in Vitamins and Hormones. Actin regulation is covered directly by a 2018 article (Expert Opinion on Biological Therapy).
Mind the names. TB-500 and full thymosin β4 are different molecules. TB-500 is the short synthetic fragment. Many papers study the whole 43-residue protein. The registry data below refers to the fragment.
Written for education from published papers. It promises no result to anyone who buys, and NordPeps sells TB-500 for laboratory research only.
Unopened vials. Store at 2–8 °C. For long periods, −20 °C or colder. Room temperature is fine in transit, but it is not a way to store a peptide.
After reconstitution. Refrigerate at 2–8 °C. Do not freeze: ice crystals break the peptide down for good. In bacteriostatic water (0.9% benzyl alcohol), labs usually work through a vial within about 30 days. With plain sterile water, the window is 24–48 hours.
Keep vials closed and out of the light. If you hold frozen stock, thaw it as few times as you can; each cycle loses some activity.

A 10-vial kit costs €289 (5 mg) or €419 (10 mg). A 30-vial kit costs three times as much (€867 or €1,257). Delivery is free on every kit, to all 27 EU countries.

No. TB-500 corresponds to one active piece of thymosin β4. It is not the full protein. Laboratory research use only.
We sell this compound only in sealed kits of 10 identical vials, or 30. A 10-vial kit is the smallest order.
Unopened: 2–8 °C; for long stretches, −20 °C. Reconstituted: in the fridge, never frozen. Details are under storage and handling.
By the volume of bacteriostatic water you add, not by the vial size alone. Enter the vial size and the diluent volume in the reconstitution calculator and it gives you the concentration.
Kits leave us 24–48 hours after payment, in a plain box with tracking. Delivery stays within the EU. Laboratory research use only.
