TB-500 is a synthetic version of a peptide fragment derived from Thymosin Beta-4, a naturally occurring protein involved in actin regulation and cell migration. It is frequently studied alongside BPC-157 in tissue-repair and regenerative-research literature.
Research-grade TB-500 is typically supplied as a lyophilized powder in sealed vials at strengths commonly ranging from 2mg to 10mg, intended for laboratory reconstitution and research use only.
TB-500 is a fragment of the actin-binding protein Thymosin Beta-4. Research suggests it may influence cell migration, angiogenesis, and the formation of new blood vessels and muscle fibers, which are the mechanisms most commonly cited in wound-healing and cardiac-repair studies.
Preclinical studies have investigated Thymosin Beta-4 fragments for their potential role in accelerating dermal wound closure and skeletal-muscle repair through effects on cell migration and angiogenesis.
A portion of the Thymosin Beta-4 literature has examined its effects in animal models of cardiac injury, where researchers have investigated its role in supporting vascular formation and reducing scar tissue after ischemic injury.
Human safety data for TB-500 is limited, as it is not FDA-approved and has not completed large-scale human trials. Reported concerns in available reports include injection-site reactions and transient fatigue; long-term human safety remains uncharacterized.
Doses reported in animal studies vary widely by model and body weight and do not translate to an established human dose. No clinically approved human dosage exists for TB-500.
Compound X does not sell TB-500 (Thymosin Beta-4) directly. We provide independent research, comparisons and vendor links — see the vendor comparison table above for current US, UK, Canada and Australia options.
Peer-reviewed Thymosin Beta-4 research is indexed on PubMed under search terms such as "Thymosin Beta-4 wound healing" and "TB-500 tissue repair."
