Buy TB-500 (Thymosin Beta-4) 10mg in Australia
Thymosin Beta-4 derived tissue repair research peptide
Looking to buy TB-500 in Australia? Aussie Peptide Store supplies research-grade TB-500 10mg vials from local Australian stock, independently COA verified at 99%+ purity and dispatched same business day from Sydney with tracked delivery to every state and territory. Also searched as TB500, TB 500, thymosin beta 4 and Tβ4.
TB-500 is a synthetic peptide based on the active region of Thymosin Beta-4, a naturally occurring 43-amino-acid protein central to cell migration and tissue regeneration. It is one of the most studied systemic repair compounds, frequently researched alongside BPC-157.
Key Research Areas
Studied for sequestering G-actin and driving cell movement to injury sites
Studied for connective tissue healing and flexibility
Studied across muscle injury and overuse models
Studied for new blood vessel formation and improved perfusion
Studied for modulating inflammatory response during repair, including corneal and dermal wound models
Each TB-500 vial is supplied as a lyophilised powder at 10mg. Every batch is independently analysed by Janoshik Analytical, with purity, heavy metals and endotoxin results published in our COA library. Background reading: Goldstein et al., Expert Opinion on Biological Therapy 2012 (thymosin β4 in tissue repair) and Sosne et al., Annals of the New York Academy of Sciences 2010 (wound healing and anti-inflammatory activity).

TB-500 Australia FAQ
Where can I buy TB-500 in Australia?
You can buy TB-500 in Australia directly from Aussie Peptide Store. Vials are held in local Australian stock and shipped from Sydney with same business day dispatch on orders cleared before 12pm AEST. Every order is tracked, with no customs delays or international freight waits.
Is TB-500 available in Australia?
As a research compound, yes: held in Sydney, ships same day. As a medicine, no. As of September 2026 TB-500 is not TGA approved, not on the ARTG and not stocked by pharmacies or compounding chemists.
Can I buy TB-500 at Chemist Warehouse?
No. TB-500 is not a registered medicine and is not sold through any Australian pharmacy. It is available only as a research reagent.
How much does TB-500 cost in Australia?
Pricing for the 10mg vial is shown above. There are no card surcharges on Osko, PayID or bank transfer payments, and standard shipping is free over $100.
What is TB-500?
TB-500 is a synthetic fragment of Thymosin Beta-4, a protein found in almost all cells that plays a key role in tissue repair. The fragment retains the region responsible for actin binding and cell migration.
How does TB-500 work?
Research points to TB-500 binding G-actin, which lets cells move more efficiently to damaged tissue. It is also studied for promoting angiogenesis and reducing inflammation across systemic repair models.
Is TB-500 the same as Thymosin Beta-4?
TB-500 is a synthetic peptide based on the active portion (residues 17 to 23, the actin-binding LKKTETQ region) of the full 43-amino-acid Thymosin Beta-4 protein. It reproduces the key repair-related region, which is why the two are often described interchangeably in research.
Can TB-500 be combined with BPC-157?
TB-500 and BPC-157 are one of the most researched repair pairings. They are studied for complementary action, with BPC-157 focused on localised healing and TB-500 on systemic cell migration. The pre-mixed blend supplies both in one vial.
How do you reconstitute TB-500?
Add bacteriostatic water slowly, directing the stream down the inside wall of the vial rather than onto the powder directly. 2mL gives 5mg/mL, so 1mg is 20 units on a U-100 syringe. Swirl gently to dissolve, never shake. Refrigerate at 2 to 8°C afterwards and use within 8 to 12 weeks.
Is TB-500 legal in Australia?
TB-500 is supplied strictly for lawful in-vitro laboratory research. It is not TGA approved for human or veterinary use and is not sold as a medicine, supplement or therapeutic good. Purchasers are responsible for ensuring their use complies with applicable laws.
