TB-500 is a research synthetic peptide based on an active region of beta-4 thymosin, a protein naturally present in the body and related to tissue repair processes.

It is used as a reference compound in experimental models of recovery, cell mobility, and regeneration.

At KaiLab, peptides are supplied as a freeze-dried powder intended exclusively for scientific research. It is not approved for human or veterinary use.

These recommendations apply to all KaiLab freeze-dried peptides.

Freeze-dried powder (not reconstituted):
– Store at −20 °C for long-term storage.
– Protect from light and keep in a dry environment.
– Under these conditions it maintains its stability for extended periods.

Reconstituted (in solution):
– Reconstitute routinely with bacteriostatic water, under laboratory conditions.
– Store refrigerated (2°C to 8°C).
– Avoid repeated freezing and thawing cycles.
– Handle with aseptic technique and appropriate laboratory equipment.

These instructions pertain solely to the handling of research materials.

TB-500 is primarily being studied in areas related to tissue repair:
– Tissue repair and recovery
– Muscle recovery and flexibility
– Wound healing
– Formation of new blood vessels (angiogenesis)
– Inflammatory processes associated with recovery
