Ships from IrelandTB-500 (TB4)
TB-500 is a peptide related to a small part of a natural body substance called thymosin beta-4, which plays a role in how the body repairs tissue. It's studied for how it affects cell movement and blood vessel growth, and its possible relevance to muscle and joint research.

Storage & Preparation
Keep sealed, cool, dry and away from direct light.
Refrigerate or freeze for longer-term storage. Brief periods at room temperature, including during delivery, are generally not a concern.
Refrigerate at 2–8°C and protect from light.
Avoid repeated freeze/thaw cycles. Stability varies by compound, so follow any product-specific guidance.
Preparation solution is not included and must be purchased separately. Add the appropriate solution slowly against the inside wall of the vial, then gently swirl until dissolved. Do not shake.

Research Information
What Is TB-500?
TB-500 is an investigational peptide currently being studied for tissue repair in laboratory research. It is supplied as a freeze-dried powder.
Why Is It Being Researched?
Thymosin beta-4, the natural substance TB-500 is related to, comes up again and again in tissue-repair studies, which is why peptides related to it get so much research attention — often alongside BPC-157.
Preclinical research on thymosin beta-4 has looked at cell migration, new blood vessel formation and inflammation. One honest note: the name "TB-500" isn't used consistently — some published research covers the full-length natural substance, while "TB-500" as sold commercially is often a shorter, related fragment. It's worth checking exactly what a batch contains via its results certificate rather than assuming. Human trials specific to TB-500 remain limited.
