TB-500 is a synthetic version of a fragment of Thymosin Beta-4, a naturally occurring protein involved in cell migration and wound healing. It is marketed for injury recovery and reducing inflammation, often alongside BPC-157.
Most evidence comes from animal and cell-based studies of the naturally occurring Thymosin Beta-4 protein, showing a role in wound healing and tissue repair processes. Direct human clinical evidence for the synthetic TB-500 product sold online is very limited.
As an unregulated research chemical, purity and dosing are unverified. Reported side effects in anecdotal use include headache, nausea and fatigue, though this is not from controlled clinical data. Long-term safety in humans is unknown.
Legal and research status: this peptide is typically sold as a research chemical, labelled not for human consumption, and is not an approved medicine or supplement in the UK, EU or US. Buying it for personal use sits in a legal grey area, and product purity and dosing are not independently verified or regulated. There is no approved medical indication for TB-500. Discuss injury recovery options with a doctor or physiotherapist rather than sourcing an unregulated peptide.
Sold online as a research chemical, priced per vial.
