What TB-500 Is

TB-500 is a lab-made piece of a natural repair protein your body already produces. Researchers use it to study recovery across many tissues at once, rather than in one fixed spot.

The body naturally makes a protein called Thymosin Beta-4 that helps cells move, organise and repair after damage. TB-500 is a synthetic version of the active part of that protein — small, stable and easy to work with in the lab.

The detail researchers care about most is that TB-500 is systemic. Once it’s circulating it travels throughout the body rather than staying where it started, which is why it’s studied for whole-body recovery rather than one specific area.

It works largely through actin, a building-block protein involved in cell movement and structure. By influencing how cells migrate and reorganise, TB-500 is studied for tissue repair, flexibility and the formation of new blood vessels.

TB-500 vs BPC-157 vs the Blend

TB-500 and BPC-157 are studied together so often that they’re frequently combined into one product. The simplest way to see why is side by side.

BPC-157 works locally, where it’s applied. TB-500 works system-wide, across the whole body. They cover different ground, which is exactly why researchers reach for the BPC-157/TB-500 blend — and why we stock all three.

What the Research Looks At

Recovery and repair. TB-500’s parent protein is central to how cells travel to damaged areas, so most research looks at soft-tissue, tendon and muscle recovery.

Blood-vessel formation. Like BPC-157, TB-500 is studied for angiogenesis — the growth of new blood vessels — which supports how tissue rebuilds itself.

Flexibility and inflammation. Because it acts across the whole body, researchers also look at how TB-500 affects flexibility and the inflammatory response in several tissues at once.

Why Source TB-500 Locally in Thailand

Buying TB-500 from overseas means customs delays, long transit and temperature swings that can quietly degrade a peptide before it arrives. Sourcing locally removes all three.

Bangkok Peptides keeps stock in Bangkok, ships from Bangkok, and delivers across Thailand on tracked services — so you get your order in days, not weeks, with a handling chain you can actually verify.

Delivery Across Thailand

We ship TB-500 nationwide by tracked courier. Most orders qualify for same-day or next-working-day dispatch from Bangkok, with arrival depending on where you are.

Reconstitution & Handling

TB-500 arrives as a freeze-dried (lyophilised) powder in a sealed sterile vial. Before any research use it needs mixing with bacteriostatic water. Standard lab handling applies.

Add the water slowly down the inside wall of the vial — not straight onto the powder — then swirl gently until it dissolves. Don’t shake. The solution should look clear.

Keep the sealed vial cool, dry and out of direct light before mixing. Once mixed, store it in the fridge at 2–8°C, which matters in Thailand’s heat. Avoid repeated freeze–thaw cycles. Sealed vials keep for up to 24 months when stored properly.
