TB-500 5 mg — Research Consultation

TB-500 is a 17-amino-acid synthetic fragment based on the active region of thymosin β4, a naturally-occurring polypeptide central to cellular actin sequestration. The published animal-research literature spans cardiac-tissue, dermal-wound, and corneal-repair models. This page summarises the mechanism and links you into a research consultation with Nour.

What TB-500 is

TB-500 is a synthetic peptide derived from the actin-binding domain of thymosin β4, a 43-amino-acid endogenous polypeptide. The synthetic fragment retains the actin-sequestering region of the parent molecule, which is the mechanism most often cited in the published research. TB-500 is not identical to thymosin β4 — researchers reading the literature should distinguish the full-length protein research from the synthetic fragment research.

What the published literature covers

Animal-research literature on thymosin β4 and TB-500 spans cardiac-tissue regeneration models (post-infarction remodelling studies), dermal wound-healing research (full-thickness skin models, diabetic ulcer models), corneal repair (epithelial migration studies), and inflammatory pathway interactions. As with most research peptides, human clinical evidence is limited — researchers should distinguish preclinical findings from extrapolated claims.

Quality verification

Lyophilised TB-500 5 mg manufactured under ICH Q7 GMP standards, with independent HPLC verification at a US-based third-party laboratory. Peak-area purity ≥98% at λ=214 nm against pharmacopoeia reference standards. Each released batch carries a Certificate of Analysis available through the in-chat consultation.

Talk to Nour before you commit

Nour walks through the protocol options published in the TB-500 research literature, including the distinction between TB-500 alone and the BPC-157 + TB-500 blend, and helps you decide which fits your research question. English or Arabic.

Common research questions

Is TB-500 legal in the UAE?
TB-500 is classified as a research compound in the UAE and is sold through standard wellness-supply channels. Wellness Labs operates under standard UAE commercial trading rules with VAT compliance applied to every dispatch.
What dose ranges does the published research use?
Animal-research protocols vary from 0.1 to 5 mg/kg. In the grey-research community, human protocols commonly described range from 2-10 mg per week, often divided into 2-3 doses, in cycles of 4-6 weeks followed by a maintenance period. No consensus optimal protocol exists in the human research literature.
TB-500 vs. thymosin β4 — are they the same molecule?
No. Thymosin β4 is a 43-amino-acid endogenous polypeptide. TB-500 is a 17-amino-acid synthetic fragment containing the actin-binding region. They share the core mechanism cited in the literature but are not identical compounds. Most published research uses the full-length molecule; the synthetic fragment is more commonly used in grey-research contexts.
TB-500 alone or BPC + TB-500 blend?
TB-500 and BPC-157 act through largely independent pathways — TB-500 via actin sequestration and cell migration, BPC-157 via growth-factor expression and angiogenesis signalling. Researchers studying single-pathway questions use TB-500 alone. Researchers studying combined tissue-recovery pathways sometimes use the blend.
How is purity verified?
Every released batch carries a Certificate of Analysis showing HPLC peak-area purity at a US-based third-party laboratory. Method specifications are published on our quality page. Customers can request the chromatogram through the chat.
Shelf life and storage?
Lyophilised TB-500 is ambient-temperature stable in transit. Long-term storage at -20°C protected from light. After reconstitution, refrigerated storage with appropriate handling per the supplied protocol.
How fast is delivery in the UAE?
Same-day delivery within Dubai, next-business-day across the rest of the UAE.
