Protocol
Storage & Handling
Long-Term Storage
Store lyophilized peptide at −20°C. Under these conditions the product remains stable for up to 24 months from the date of manufacture.
After Reconstitution
Once reconstituted, store at 4°C and use within 30 days. Avoid repeated freeze-thaw cycles as this may degrade compound integrity.
Shipping Conditions
All orders ship in insulated packaging with cooling packs to maintain the cold chain during transit. Free on every order, no minimum required.

Frequently Asked Questions
TB-500 is a synthetic 43-amino-acid peptide that replicates the active region of thymosin beta-4 (Tβ4), a naturally occurring protein found in nearly all human and animal cells involved in actin regulation and tissue repair. Its low molecular weight and water solubility enable efficient tissue penetration in laboratory settings.
BPC-157 targets vascular integrity, VEGFR2 angiogenic signaling, and matrix organization. TB-500 acts primarily through actin dynamics, cell migration, and satellite cell activation. Together they address complementary repair pathways — which is why they are frequently co-researched and available as our Wolverine Blend (5mg/5mg).
Add bacteriostatic water slowly along the vial wall and gently swirl until dissolved. TB-500 is a large 43-amino-acid peptide and may take slightly longer to fully dissolve — do not shake. Use our Reconstitution Calculator for volume guidance.
TB-500 (thymosin beta-4) is not approved by the FDA for any medical use and is prohibited by WADA under class S0 (Non-Approved Substances). Our product is strictly research-grade, for in vitro laboratory use only. Not for human or animal consumption.
Our TB-500 is verified at ≥98% purity via third-party HPLC analysis. The current batch is confirmed at 98.8% by Apex Analytics Lab. A full COA ships with every order.
