Written by Peptide Association Editorial TeamMedically reviewed by Ian Justl Ellis, MD, CPTLast reviewed Editorial policy

Overview

Pentadeca Arginate is a synthetic 15-arginine polypeptide designed to enhance cellular uptake and delivery of therapeutic molecules. The polyarginine structure confers cell-penetrating properties by interacting with negatively charged cell membrane components.

Mechanism of Action

It has been explored as a carrier for facilitating intracellular delivery of bioactive compounds and as a potential modulator of tissue repair processes.

Research Summary & Key Findings

Preclinical in vitro studies have demonstrated efficient cellular internalization and low cytotoxicity in various cell lines. Animal studies investigating wound healing and tissue repair applications have shown preliminary evidence of enhanced regeneration, though mechanisms remain incompletely characterized. No clinical trial data in humans are currently available.

Clinical Status

Research Phase

Pentadeca Arginate (PDA) is in the research phase with limited clinical data in humans. Current evidence is primarily derived from preclinical (animal or in vitro) studies.

No lawful pathway today

Pentadeca Arginate (PDA) 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.
