Peptides are short chains of amino acids that serve as building blocks of proteins. In research settings, peptides are studied for their roles in tissue healing, metabolic regulation, and cellular signaling.

Are your products for human consumption?

No. All BLL Peptides products are strictly for in-vitro research and laboratory use only. They are not intended for human or animal consumption.

What is a Certificate of Analysis (COA)?

A COA verifies purity and identity. Every BLL Peptides batch includes HPLC and mass spectrometry results confirming 98%+ purity.

Where are BLL Peptides products manufactured?

All products are 100% USA-manufactured in GMP-certified facilities with independent third-party testing on every batch.

Do you offer free shipping?

Yes — free shipping on all orders over $150 within the continental United States. Orders ship Monday through Friday.

How should peptides be stored?

Lyophilized peptides should be stored at -20°C for long-term stability. Once reconstituted, store at 4°C and use within a few weeks.

TB-500 is a synthetic version of Thymosin Beta-4 (Tb4), a 43-amino acid peptide found naturally in virtually all human cells. It plays a role in actin polymerization, cell migration, angiogenesis, and tissue repair. In research, TB-500 refers to the biologically active fragment of Tb4 that is responsible for most of its studied bioactivity in recovery and regeneration models.

What purity is BLL Peptides TB-500?

BLL Peptides TB-500 is produced at 98%+ purity, confirmed by independent third-party HPLC analysis. A Certificate of Analysis is available for every production batch and can be provided on request before purchase.

How should TB-500 be stored?

Lyophilized TB-500 should be stored at 2-8 degrees C for short-term use or -20 degrees C for long-term storage. Protect from direct light and moisture. Once reconstituted with bacteriostatic water, store at 4 degrees C and use within 30 days. Do not freeze reconstituted product.

How does TB-500 compare to BPC-157 in research?

TB-500 and BPC-157 are both studied for tissue repair and recovery, but via distinct mechanisms. TB-500 primarily influences actin regulation and cell migration, while BPC-157 operates through nitric oxide and growth factor signaling pathways. Researchers often study both compounds for comparative analysis or potential complementary effects in healing models.

What sizes of TB-500 does BLL Peptides offer?

BLL Peptides offers TB-500 in 5mg ($49.99) and 10mg ($64.99) vials. Both are lyophilized powder in pharmaceutical-grade glass vials with Certificate of Analysis included.

What Is TB-500 (Thymosin Beta-4)?

TB-500 is a synthetic version of Thymosin Beta-4 (Tb4), a naturally occurring 43-amino acid peptide found in virtually all human and animal cells. Thymosin Beta-4 is encoded by the TMSB4X gene and plays a critical role in actin polymerization, cell migration, angiogenesis, and wound healing. TB-500 represents the biologically active fragment of Tb4 — the segment responsible for most of its studied bioactivity. Over the past two decades, preclinical research has examined TB-500’s potential in models of tissue repair, inflammation modulation, cardiac recovery, and neurological regeneration.

Key Research Areas for TB-500

TB-500 has been studied across multiple recovery and regeneration domains:

Musculoskeletal Repair: Multiple preclinical studies have explored TB-500’s influence on muscle fiber regeneration, satellite cell activity, and tendon healing following injury models.
Cardiac Recovery: Research has examined Thymosin Beta-4’s role in cardiomyocyte survival, angiogenesis, and post-infarction repair in animal models.
Wound Healing: TB-500’s role in keratinocyte migration, angiogenesis, and extracellular matrix remodeling makes it a frequent subject in wound biology research.
Inflammation Modulation: Studies have investigated TB-500’s anti-inflammatory signaling, particularly its interaction with NF-kB pathways.
Neurological Recovery: Emerging research is exploring TB-500’s potential in models of traumatic brain injury and spinal cord damage.

TB-500 vs BPC-157: Research Comparison

TB-500 and BPC-157 are frequently compared in recovery research. While both influence healing pathways, their mechanisms differ significantly: TB-500 primarily operates through actin regulation and cell migration, while BPC-157 works largely through nitric oxide and growth factor signaling. Some researchers study them in combination for additive or synergistic effects in tissue repair models.
