TB-500

TB-500 is a synthetic peptide fragment derived from Thymosin Beta-4, a naturally occurring actin-binding protein involved in cell migration and structural remodeling. In preclinical research, it's been studied for its role in wound-healing models, tissue-repair pathways, and angiogenesis, often as a comparator or complement to BPC-157 in combined-injury research designs.

Because Thymosin Beta-4 is expressed across many tissue types, TB-500 shows up in a broad range of research contexts — from cardiac tissue studies to soft-tissue and mobility-related models — making it a frequently referenced compound in regenerative-research literature.

This product is intended strictly for laboratory research use. It is not a drug, dietary supplement, or food product, and is not evaluated or approved by the FDA for any use in humans or animals. It is not for human consumption.

Every lot is tested by an independent, accredited lab before it's listed — purity, heavy metals, endotoxins, and quantity — with the full Certificate of Analysis published and traceable to that specific lot.
