Introduction

Peptides are gaining attention in wound care as a potential tool to support healing. While interest is growing among clinicians and patients alike, it is important to evaluate where peptides fit within evidence-based practice.

What Are Peptides?

Peptides are short chains of amino acids that function as signaling molecules. In wound healing, they influence processes such as cellular migration, angiogenesis, collagen synthesis, and inflammation.

Why the Interest?

Chronic wounds often stall in the inflammatory phase. Peptides may help re-signal the wound environment and support progression through the healing cascade.

Common Peptides

BPC-157: Associated with angiogenesis and fibroblast activity (primarily animal data).
Thymosin Beta-4: Supports cell migration and tissue remodeling (limited human data).
LL-37: Antimicrobial peptide with potential healing support.

Evidence Overview

Most data is preclinical. Human trials are limited, and there are no standardized dosing protocols. Many peptides are not FDA-approved for wound healing indications.

Clinical Considerations

Standard wound care principles must be optimized first, including perfusion, offloading, infection control, debridement, and moisture balance. Patient expectations should be managed carefully.

Future Role

Peptides may serve as adjunct therapies in non-healing wounds or in research settings as more evidence becomes available.

Conclusion

Peptides are promising but not yet part of standard care. Providers should remain grounded in evidence-based practice while monitoring emerging research.
