Nexagon (Gap Junction Peptide)
Overview
Nexagon is a synthetic peptide designed to transiently modulate gap junction intercellular communication by mimicking a segment of the connexin protein family. The mechanism involves temporary inhibition of connexin43-mediated channels during the early inflammatory phase of wound healing, which may reduce inflammatory cell infiltration and subsequent scar formation.
Mechanism of Action
This approach aims to shift the healing process toward regeneration rather than fibrosis.
Research Summary & Key Findings
Early clinical studies in venous leg ulcers demonstrated improved healing rates and reduced scar tissue formation. A phase II trial showed statistically significant reduction in scar size when applied topically to acute wounds, though larger confirmatory trials have not been widely published.
Clinical Status
Nexagon (Gap Junction Peptide) is currently undergoing clinical trials. It is not yet FDA-approved and is available only through clinical research settings or investigational protocols.

View detailsNo lawful pathway today
Nexagon (Gap Junction Peptide) is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so there is nothing for us to sell you here and no consultation to book. That can change: eight peptides moved back to a lawful pathway in February 2026.
