TB-500 (10mg)

TB-500 is a recovery peptide derived from Thymosin Beta-4, a protein your body naturally uses to repair damaged tissue. It's studied for its ability to speed up healing in muscles, tendons, and ligaments — faster than the body can manage on its own. Researchers use it for injuries that are healing slowly, chronic soft tissue problems, and as part of recovery protocols for high-volume training. It's one of the most referenced repair compounds in peptide research, and is frequently combined with BPC-157 for a more complete healing protocol.

TB-500 is sometimes referred to as TB4, the Thymosin Beta-4 fragment, or the 'healing peptide'. It's closely related to Thymosin Beta-4 (Tβ4) but isn't the same thing — TB-500 is a targeted synthetic fragment that isolates the key repair activity of the full protein. If you've been searching for 'TB-4 peptide Australia' or 'Thymosin Beta-4 Australia', TB-500 is what you're looking for.

TB-500 works by sending repair cells to the site of injury, stimulating the growth of new blood vessels to bring oxygen and healing nutrients to damaged tissue, and reducing the inflammation that slows recovery down. In plain terms: it helps your body's repair process happen faster, more completely, and in the right order. It's especially effective for injuries involving connective tissue — tendons and ligaments — which have poor blood supply and typically heal much more slowly than muscle.

TB-500 is most commonly researched for muscle tears and strains, tendon injuries (including tendinopathy and partial tears), ligament damage, and chronic soft tissue injuries that seem to plateau rather than fully heal. It's also used as a general recovery aid by athletes and people with high training loads who want to reduce downtime between sessions. Stacking TB-500 with BPC-157 is a common approach for more comprehensive injury repair — TB-500 handles the vascular and cell migration response, BPC-157 handles tissue protection and inflammation.

They work through different mechanisms and complement each other well. BPC-157 is derived from gastric juice and is especially effective for gut lining, nerve repair, and reducing inflammation directly at injury sites. TB-500 is stronger on the vascular side — it's better at triggering new blood vessel growth into damaged tissue and driving the movement of repair cells to where they're needed. Many researchers run both together because they cover different parts of the healing process. Aussie Peptides also carries BPC-157 separately, or you can find both combined in our GLOW repair blend.

Studies have documented significantly accelerated healing in muscle, tendon, and ligament injury models. TB-500 has also shown strong results in promoting new blood vessel growth in damaged and ischaemic tissue, reducing inflammation, and supporting cardiac tissue repair. It's one of the most extensively referenced repair peptides in the literature — and consistently shows up in studies examining how to speed up connective tissue healing, which is notoriously slow even under normal conditions.

TB-500 is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 28 days. For a full step-by-step walkthrough, see our complete peptide reconstitution guide.

Store lyophilized TB-500 vials at -20°C, away from light and moisture. After reconstitution with BAC water, refrigerate at 2–8°C and use within 28 days. Do not freeze the reconstituted solution.
