Overview

Thymosin Beta-4 (Tβ4) is a 43-amino acid peptide naturally present in most tissues and cell types. It plays a critical role in tissue repair, cell migration, and anti-inflammatory processes.

Mechanism of Action

Actin regulation — Sequesters G-actin, promoting cell migration and wound healing
Anti-inflammatory — Reduces pro-inflammatory cytokines at injury sites
Angiogenesis — Promotes new blood vessel formation
Stem cell mobilization — Encourages cardiac progenitor cell migration
Anti-fibrotic — Reduces scar tissue formation

Dosing Protocols

| Phase | Dose | Frequency | Duration | |-------|------|-----------|----------| | Loading | 5-10mg | Twice weekly | 4-6 weeks | | Maintenance | 2-5mg | Once weekly | Ongoing |

Safety Profile

Tβ4 is naturally occurring in the body, contributing to a generally favorable safety profile. Human data is limited; most evidence comes from preclinical studies and clinical case reports.
