What it does

TB-500 (Thymosin Beta-4 fragment) promotes cell migration by upregulating actin, a key protein in cell structure and movement. It enhances angiogenesis, reduces inflammation, and promotes stem cell differentiation. Unlike BPC-157 which works locally, TB-500 has systemic effects throughout the body.

The loading + maintenance protocol ensures saturation before transitioning to a lower maintenance dose for continued healing support.

Dosage & Protocol

Subcutaneous injection (systemic — injection site doesn't need to be near injury). Loading: 2-2.5mg twice weekly (weeks 1-4). Maintenance: 2-2.5mg once weekly (weeks 5-12). 10 vials provides a complete 12-week cycle.

The research

📄

Wound Healing: 11%+ increased wound contraction, increased collagen deposition, 2-3 fold keratinocyte migration(10469335)

📄

Corneal Wound Healing: Human-relevant eye healing data(IOVS-2423767)

📄

Clinical Trial: Human trial of thymosin beta 4 for chronic wound healing(NCT00832091)

Safety notes

⚠️Generally well-tolerated. Mild injection site reactions. Temporary lethargy or headache during loading phase.

⚠️Theoretical concern about use with active cancers — same as BPC-157. No evidence of tumor promotion.

⚠️Thymosin Beta-4 IS on the WADA prohibited list. Athletes subject to drug testing should avoid.
