About this product
TB-500 Canada — Thymosin Beta-4 Fragment for Research TB-500 (Thymosin Beta-4 fragment) is one of the more biologically interesting peptides in tissue repair research. The parent protein, Thymosin Beta-4, is ubiquitous in mammalian cells — it's the primary actin-sequestering molecule, present in virtually every cell type and responsible for regulating the pool of monomeric actin available for cytoskeletal remodelling. TB-500 isolates the active region of that larger protein. The fragment retains the actin-binding capacity and the downstream effects on cell migration, making it a useful tool for research into tissue repair mechanisms without requiring the full 43-amino acid parent compound. Where the research gets interesting is the range of tissue types studied. The actin regulation mechanism is relevant wherever cell migration matters — which is to say, in most wound healing processes. Published studies have examined TB-500 in corneal healing, cardiac tissue following ischemia, hair follicle stem cell activation, and connective tissue repair. The half-life (~2 weeks) makes it practical for longer-duration research protocols compared to shorter-lived peptides. If you're buying...

Frequently asked
questions
What is TB-500 used for?
TB-500 is a thymosin beta-4 fragment studied for tissue regeneration research. Regulates actin for cell migration and wound healing. Published research has examined its role in injury recovery, inflammation, tissue repair.
Can I buy TB-500 in Canada?
Yes. Kirei Clinic ships TB-500 to all Canadian provinces — Ontario, British Columbia, Alberta, Quebec, Manitoba, Saskatchewan, and all territories. It's available strictly for non-clinical laboratory research purposes.
What purity is Kirei Clinic's TB-500?
Every batch is independently tested to 99%+ purity by third-party HPLC. Mass spectrometry confirms peptide identity. A Certificate of Analysis documenting purity, molecular weight, and batch data is included with every order.
How should I store TB-500?
Store lyophilized TB-500 at -20°C in the original sealed vial. After reconstitution with bacteriostatic water, refrigerate at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles — aliquot if multiple uses are planned.
How do I reconstitute TB-500?
Draw bacteriostatic water into a syringe and inject slowly against the vial wall — not directly onto the powder. Swirl gently to dissolve; never shake. Common volumes are 1 mL, 2 mL, or 2.5 mL depending on the concentration needed. Let sit for a minute if not fully dissolved.
Is TB-500 legal in Canada?
TB-500 is legal to purchase in Canada for non-clinical laboratory research. It is not approved by Health Canada for therapeutic use and is not intended for human consumption. Kirei Clinic sells it strictly for research applications.
How does TB-500 differ from bpc-157?
Both TB-500 and bpc-157 are used in tissue regeneration research research but work through different mechanisms. TB-500 is a thymosin beta-4 fragment. Researchers often study them in parallel to compare mechanism-specific effects.
What documentation comes with TB-500?
Every order includes a Certificate of Analysis (COA) with: HPLC purity results (99%+), mass spectrometry data, batch number, manufacturing date, and expiry date. This provides full traceability for research records.
