SNAP-8 (Acetyl Octapeptide-3)

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

Overview

SNAP-8 is an elongated derivative of Argireline, consisting of eight amino acids (Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2) designed to further inhibit SNARE complex formation and catecholamine-mediated neurotransmitter release. By extending the peptide sequence, the molecule is hypothesized to achieve enhanced binding and greater reduction in muscle contraction intensity in facial expression zones.

Mechanism of Action

Like its hexapeptide predecessor, it is positioned as a non-invasive topical anti-wrinkle agent.

Research Summary & Key Findings

In vitro assays have demonstrated that acetyl octapeptide-3 can reduce neurotransmitter release in cell-free models at higher potency than acetyl hexapeptide-8. Manufacturer-sponsored clinical studies have reported wrinkle depth reductions of approximately 60 percent in some participants after 28 days, though independent peer-reviewed replication is absent. Standardized efficacy benchmarks and head-to-head comparisons with established treatments have not been published.

Clinical Status

Investigational

SNAP-8 (Acetyl Octapeptide-3) is in the investigational stage. While preclinical and early-phase data exist, it has not received regulatory approval for clinical use in the United States.
