TB-500
Canada's Most Researched Recovery Peptide — Best Paired With BPC-157
TB-500 is a synthetic analogue of the naturally occurring peptide Thymosin Beta-4 (Tβ4). Research has extensively studied its role in cell migration, blood vessel formation, and cellular differentiation, primarily in the context of tissue repair and regeneration. It is consistently listed among Canada and the U.S.'s most-searched research peptides and is the #2 most-searched peptide stack in Canada when combined with BPC-157.
- Active fragment of naturally occurring Thymosin Beta-4
- Studied for cell migration, angiogenesis and tissue regeneration
- #2 most-searched recovery peptide in Canada; pairs with BPC-157

What researchers report
Aggregated, anonymized observations from laboratories ordering this compound. Anecdotal and non-clinical.
Most frequently ordered as a paired-arm study with BPC-157 rather than alone.
Researchers commonly cite its longer systemic distribution profile when designing weekly rather than daily models.
Reconstituted stability at 2–8°C is regularly reported as consistent across the 30-day window.

Research background
Thymosin Beta-4 is a naturally occurring 43-amino acid peptide; TB-500 represents the active fragment most commonly used in research to study its tissue-repair signaling pathways.
Research models have shown TB-500's role in actin sequestration, supporting cellular migration into damaged tissue regions.
TB-500 is most frequently studied in combination with BPC-157, forming the most researched recovery stack in Canada and the U.S.

TB-500 — frequently asked
Is TB-500 the same as Thymosin Beta-4?
Not identical — TB-500 is the synthetic active fragment (LKKTETQ region) of the full 43-amino-acid Tβ4 peptide.
Why is it stacked with BPC-157?
The two are studied for complementary pathways: BPC-157 for local repair signalling, TB-500 for cell migration and angiogenesis.
What purity do you guarantee?
≥98.5%, HPLC-verified per batch with a third-party COA.
How fast does it ship?
Orders placed before 2pm ET ship the same business day from Toronto with tracked Canada-wide delivery, typically arriving in 1–3 business days. Cold-pack packaging is used on every shipment.
What if the purity doesn't match the COA?
Every batch is HPLC and mass-spec verified by an ISO 17025 accredited third-party lab, and the batch-matched COA ships with your order. If an independent test comes back below the stated purity, we replace the order or refund it in full.
Is this legal to purchase in Canada?
Yes — these compounds are sold strictly as in-vitro research chemicals for laboratory use. They are not for human or veterinary use, and it is the purchaser's responsibility to comply with applicable federal and provincial regulations.
