What is TB-500?
Thymosin beta-4 is a 43-amino-acid protein found in nearly every cell, where it binds actin and helps control cell movement. TB-500 is the name used for synthetic thymosin beta-4 and for a short fragment of its active region.
It’s on the WADA prohibited list and isn’t an approved medicine.

TB-500 in published research
Goldstein and colleagues reviewed thymosin beta-4’s role in wound repair in 2012, covering faster closure of skin wounds and new blood vessel growth in animal models.
Bock-Marquette and colleagues reported in Nature (2004) that thymosin beta-4 improved heart cell survival after injury in mice.

Reconstituting TB-500 for research
TB-500 arrives as a freeze-dried (lyophilized) powder in a sealed glass vial. It has to be dissolved before use, and for most peptides that means bacteriostatic water. Let the water run slowly down the inside wall of the vial, then swirl gently until the solution is clear. Don’t shake it.
The amount of water you add sets the concentration. For example, adding 2mL of bacteriostatic water to a 2mg vial gives 1mg per mL. Write the volume and the date on the label so anyone picking up the vial later knows what’s in it.
We sell bacteriostatic water in 30mL vials, and acetic acid solution for the few peptides that don’t dissolve well in water.
Choosing a TB-500 vial size
The vial comes in 10mg vial with spray solution, 5mg vial with spray solution, 2mg vial with spray solution, 2mg, 5mg and 10mg. The contents are the same apart from the amount, so the choice comes down to how much your study needs and how quickly you’ll use a mixed vial.
Mixed peptides don’t last as long as dry ones, so several smaller vials can work out better than one large one if you’re running a slow study.
Purity testing for TB-500
We test each batch of TB-500 by LC-MS, which pairs liquid chromatography with mass spectrometry. The chromatography splits the sample into its components and the mass spectrometer identifies them, which tells you both identity and purity. This batch came in at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storing your TB-500
Keep it in the fridge at 2 to 8°C and don’t freeze it. Once mixed, keep the vial in the fridge and use it within a few weeks. Unmixed vials keep much longer, so only reconstitute what you need. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the TB-500 peptide vial
Does TB-500 come with water to mix it?
No. The vial holds only the freeze-dried powder. Add bacteriostatic water to your order if you don’t already have some.
How long does mixed TB-500 last?
Kept in the fridge, most reconstituted peptides are good for a few weeks. Unmixed vials last much longer, especially in the fridge or freezer.
Is the TB-500 peptide vial in stock?
Yes. Every option on this page is in stock and ready to ship.
