Why Buy TB-500 (Thymosin Beta-4) 10mg from Peptide Scientists
TB-500 is the systemic counterpart to BPC-157 — together they form the most studied recovery stack in peptide literature. Buying both unlocks complementary mechanisms for accelerated repair research.
Our TB-500 ships as ≥98% HPLC-verified lyophilized powder from Phiogen, our Iceland-based supplier with full QC documentation on every batch.
$59.99/vial with a long ~10-day half-life means each vial covers extended research protocols at low per-day cost.
About TB-500 (Thymosin Beta-4) 10mg
TB-500 is the synthetic Ac-LKKTETQ active fragment of Thymosin Beta-4 (Tβ4), a 43-amino-acid peptide present in virtually all nucleated cells.
Primary mechanism: G-actin sequestration via the Ac-LKKTETQ motif. This regulates actin polymerization, promoting cell migration, angiogenesis, and tissue repair. TB-500 also activates muscle satellite cells, upregulates ECM-remodeling metalloproteinases, and reduces TNF-α and IL-1β.
Distinct from BPC-157 (which works locally at injury sites), TB-500 distributes systemically with a ~10 day half-life. Together they cover both local angiogenic repair and systemic cell migration — the most studied combination in regenerative peptide research.
Key Features

- Synergistic with BPC-157 for tissue repair stacks
- ~10 day half-life — fewer injections per week
- Satellite cell activation for muscle regeneration
- ≥98% HPLC verified, free US shipping over $200
