    About TB-500 as a research compound

    TB-500 is a research-grade synthetic peptide based on the bioactive central region of Thymosin Beta-4, a 43-amino-acid actin-sequestering protein found throughout mammalian tissues. The TB-500 fragment retains the LKKTETQ actin-binding motif that drives much of Thymosin Beta-4's documented activity in tissue-repair, angiogenesis, and cell-migration models.

    Research applications span tendon and ligament repair studies, cardiac infarct recovery models, corneal wound healing, hair follicle growth research, and inflammation-modulation work. TB-500 is frequently used alongside BPC-157 in synergistic-pathway studies, and Peptx stocks a pre-formulated BPC + TB blend for laboratories running combined studies.

    All TB-500 ships as lyophilised powder under inert atmosphere with desiccant. HPLC and Mass Spectrometry tested at the manufacturer (documentation not shipped with orders); certificates published in the COA Library where available.

    Why research labs buy TB-500 (Thymosin B4) from Peptx

    Factory-direct sourcing

    Peptx sources directly from manufacturers cross-referenced against independent ISO 17025 lab testing. No middlemen and no compounding-pharmacy markups; just the factory price plus a small fixed margin.

    Manufacturer HPLC data

    Manufacturer HPLC and Mass Spectrometry data sits behind Peptx material at typically 99%+ purity (HPLC). Documentation is not shipped with orders. Independent ISO 17025 lab retesting is encouraged; a 14-day refund window applies to any independently verified result below the product's stated guaranteed minimum purity.

    TB-500 (Thymosin B4) buying FAQ

    What vial sizes of TB-500 do you stock?▼
    Peptx stocks TB-500 in 2mg, 5mg and 10mg lyophilised vials. The 5mg size is the most commonly ordered for standard research studies.
    What is the difference between TB-500 and Thymosin Beta-4?▼
    Thymosin Beta-4 is the full 43-amino-acid native protein. TB-500 is a synthetic 17-amino-acid fragment built around the central actin-binding LKKTETQ motif, which is responsible for most of the published bioactivity in tissue-repair models. The fragment is more cost-effective to synthesise and is the standard form used in research literature.
    Can TB-500 be combined with BPC-157?▼
    Combined BPC-157 and TB-500 studies are common in tissue-repair research. Peptx stocks both as separate vials and as a pre-formulated BPC + TB blend in 4mg, 10mg and 20mg sizes for synergistic studies.
    How should TB-500 be stored?▼
    Lyophilised TB-500 is stable at room temperature for shipping and short-term storage but should be transferred to -20 Celsius freezer storage for long-term use. Once reconstituted with bacteriostatic water, refrigerate at 2 to 8 Celsius and use within 4 to 6 weeks.
    Is TB-500 legal to buy for research?▼
    TB-500 is not a controlled substance in any major Western jurisdiction and can legally be purchased for in-vitro research. It is not approved by any major regulator for human therapeutic use. All Peptx products are sold strictly for in-vitro laboratory research and are NOT for human or animal consumption.
