TB 500 by British Dragon
TB 500 from British Dragon Pharmaceuticals is a research peptide supplied as a 2 ml vial at 5 mg per ml. The active substance is Thymosin beta 4, and the pack arrives as lyophilized powder.
Peptide labels use a language of their own, and the TB 500 label carries two numbers that get read the wrong way more often than any other. Knowing what they mean changes how you plan a study and how you mix the vial.
Reading The TB 500 Label
- 2 ml - the volume of the vial once the powder is dissolved.
- 5 mg per ml - the concentration at that volume, which means the vial holds 10 mg of peptide in total.
- Lyophilized - the powder is freeze dried, which is why it keeps far longer than a mixed solution.
Those two numbers decide how much bacteriostatic water you add and how you note the concentration afterwards. A study that records the wrong concentration can be impossible to compare against another, which is the practical reason this matters more than it sounds. Always add water slowly down the inside wall of the vial and roll it gently, never shake, then note on the vial what you mixed.
Research Areas For TB 500
- Tendon and ligament repair - studied in connective tissue healing models.
- Wound closure - tested for how quickly tissue rebuilds.
- Muscle repair - examined after heavy mechanical stress.
- Inflammation - looked at for swelling markers after injury.
- Cell migration - studied for how repair cells reach a site.
All of this is laboratory research. TB 500 is not a medicine and is not sold for human use.
Vial Details
- Manufacturer: British Dragon Pharmaceuticals
- Pharmaceutical name: Thymosin beta 4
- Pack: 2 ml vial, 5 mg per ml
- Form: lyophilized powder for stability
Storing TB 500
Keep the sealed vial cool, dark and dry. Once mixed, store it in a fridge between 2 and 8 degrees Celsius and use it within a few weeks. Do not shake it. Roll it between your hands to mix, and work with clean tools.
Stacks Other Labs Use
TB 500 is normally run with a partner. BPC 157 by Peptide Hubs covers the repair signal, and the TB 500 and BPC 157 Peptide Stack by Peptide Hubs combines them. Order Bacteriostatic Water at the same time so you can mix as soon as the parcel lands. For other makers of the same peptide, see TB 500 by Peptide Hubs or TB 500 by Kalpa Pharmaceuticals.
Common Questions About TB 500
How much peptide is in the vial?
10 mg in total. The label shows 5 mg per ml across a 2 ml vial.
Do I need a prescription?
No. You can buy TB 500 without prescription from our shop.
Why does the label matter for a study?
Because concentration has to be recorded correctly for one batch to be comparable with the next.

| How the math works | |
| 1. Find the concentration | Divide the peptide in the vial by the water added. For example, 5 mg ÷ 2 mL = 2.5 mg/mL, which is 2,500 mcg/mL |
| 2. Work out the volume | Divide the dose by the concentration. For example, 100 mcg ÷ 2,500 mcg/mL = 0.04 mL |
| 3. Convert to units | On a U-100 syringe, multiply the mL by 100. For example, 0.04 mL = 4 units |
| 4. Check the syringe | Make sure the amount fits the syringe you are using |
| Worked example | |
| Vial | 5 mg TB-500 |
| Water | 2 mL bacteriostatic water |
| Dose | 100 mcg |
| Syringe | 100 units (1 mL) |
| Concentration | 5 mg ÷ 2 mL = 2,500 mcg/mL |
| Amount to draw | 100 mcg ÷ 2,500 mcg/mL = 0.04 mL, which is 4 units on a U-100 syringe |

Reconstitution & Storage
Mixing a peptide takes about a minute. What people usually get wrong is what happens afterwards. Work through the steps in the guide above, then store the vial the way we lay out further down.
How to Reconstitute
The five steps above cover it. Let the vial and the bacteriostatic water sit out until they reach room temperature. Then run the bacteriostatic water down the inside wall of the vial, slowly, so it does not foam up. Swirl it gently until the powder is gone. Do not shake the vial, and do not squirt the bacteriostatic water straight onto the powder.
How to Store the Mixed Peptide
As soon as it is mixed, put the vial back in the fridge. 2 to 8°C (35.6°F to 46.4°F) is what you want, and it stays there until you have used it up. Write the mixing date on the label. Do not rely on memory for that.
- Temperature: an ordinary fridge, 2 to 8°C (35.6°F to 46.4°F). Not the freezer, not a kitchen cupboard.
- How long it lasts: around 4 weeks. Anything past 28 days goes in the bin.
- Light: keep it in the box or in a dark drawer. Light breaks peptides down.
- Handling: wipe the stopper with an alcohol swab before each draw, use a new needle and do not shake it. Swirl if it needs a mix.
- Freezing: never freeze a mixed solution. Ice crystals form, and a freeze and thaw cycle costs you potency.
- Throw it out if: the liquid goes cloudy, changes colour, or you can see particles in it.
The dry powder is much easier to keep. Store it dry and away from light, at room temperature if it is only for a short while, or at -20°C for the long term. Only mix what you are going to use.
