Description
TB500 10mg: Research-Grade Peptide for Laboratory Studies
TB500 10mg, also known as Thymosin Beta-4, is a high-purity, research-grade peptide designed for controlled laboratory studies in cellular and tissue models. This peptide is intended exclusively for scientific research and experimentation and is not approved for human consumption, clinical use, or veterinary applications.
Other sizes. The same compound is also supplied as a 5mg vial, and blended with BPC-157 in a two-peptide vial.
What is TB500?
TB500 is a synthetic peptide derived from Thymosin Beta-4, a naturally occurring peptide fragment. It is commonly used in research to investigate:
Cellular pathways and tissue models
Cell migration and extracellular matrix dynamics
Vascular signalling in laboratory tissue models
Muscle, tendon, ligament, and connective tissue experimental models
Multi-phase laboratory protocols for in vitro or ex vivo research
The 10mg vial size provides sufficient quantity for repeated, multi-dose, or extended experimental designs.
Key Research Applications of TB500 10mg
Tissue and Muscle Studies – Suitable for experiments involving muscle fibers, tendons, ligaments, and connective tissue models.
Cellular Pathway Exploration – Research focused on peptide-mediated cellular signaling and extracellular matrix interactions.
Vascular Signalling Models – Laboratory investigation of new blood vessel formation in controlled experimental systems.
Repeat-Exposure Experimental Designs – Compatible with short-term, long-term, or repeated experimental applications.
Experimental Tissue Models – Research in controlled in vitro or ex vivo studies involving soft tissue, cartilage, or skeletal muscle.

Compound identity and specification
Identity data for TB-500, published so the material can be checked against an independent record rather than taken on trust. The formula, mass and registry number below are verified against PubChem and can be looked up directly.

Analytical note — TB-500. TB-500 is the short acetylated fragment, not full-length thymosin beta-4, which is a 43-residue protein of about 4,963 g/mol. The two are routinely conflated. A mass near 889 confirms the fragment; a mass near 4,963 would be a different product entirely.
Identity references The molecular formula, molecular mass and CAS registry number above are taken from the PubChem record linked in the table, not from a supplier datasheet, so every figure can be checked against an independent source in one click. Sequences are given as reported in the peptide literature, in the one-letter or three-letter convention as appropriate, with any non-standard residue named in full. Where a compound exists in more than one form — a free peptide and a metal complex, a fragment and its parent protein, a modified and an unmodified analog — the form supplied is the one identified here, and the mass on the certificate of analysis is what distinguishes it.
