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.

Research on TB-500

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.

How the TB-500 nasal spray works

The TB-500 nasal spray comes as a liquid in a metered spray bottle, so it’s already in solution and there’s no powder to mix. A metered pump gives roughly the same volume with every press, which makes it easy to keep amounts consistent.

Prime the pump with a few presses before the first use, until you get a fine, even mist. Keep the nozzle clean and capped between uses, and note the number of sprays you use in your records.

Choosing a TB-500 spray size

The spray comes in 10mg in 15mL, 5mg in 15mL and 2mg in 15mL. Pick the size that matches how fast you’ll use it, since an opened bottle is best used within a few weeks.

How we test 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. Keep the bottle upright with the cap on, and wipe the nozzle after use. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
