It has also been shown in research to improve hormone levels and physical performance
Our approach emphasizes consistency, transparency, and attention to detail at every stage of production

Note: TB-500 is far less studied than full-length Thymosin -4, and the following effects are primarily supported for the parent compound: Actin Binding: Sequesters G-actin monomers, regulating cytoskeletal dynamics essential for cell movement (PMID: 22074294 - Thymosin -4) Cell Migration: Enables endothelial cells, keratinocytes, and other repair cells to migrate to injury sites (PMID: 22074294 - Thymosin -4) Anti-inflammatory: Reduces inflammatory cytokines and promotes resolution of inflammation (PMID: 30116499 - Thymosin -4) Matrix Metalloproteinase Regulation: Modulates tissue remodeling enzymes for proper scar formation (PMID: 16607611 - Thymosin -4) Stem Cell Recruitment: May enhance mobilization of stem cells to damaged areas (PMID: 22074294 - Thymosin -4) Complementary Action: BPC-157 establishes the blood supply (angiogenesis) needed for healing, while TB-500 facilitates the cellular migration and tissue remodeling that follows

The FDA's compounding-related classification of BPC-157 has been the subject of significant discussion in early 2026, and the regulatory landscape may continue to evolve
