SNAP-8, or acetyl octapeptide-3, is a synthetic peptide derived from the N-terminal sequence of SNAP-25 — a protein component of the SNARE complex involved in vesicle fusion and neurotransmitter release at neuromuscular junctions. Research interest in SNAP-8 centres on its apparent ability to compete with SNAP-25 during SNARE-complex assembly, which has made it a research tool in studies examining acetylcholine-release mechanisms and neuromuscular signalling.
Studies have investigated SNAP-8 in cell-culture and ex-vivo models examining how SNARE-protein competition influences vesicle-mediated neurotransmitter secretion. The peptide's mechanism of action — interfering with the SNARE complex at the pre-synaptic level — offers a distinct pharmacological probe compared with enzyme-based approaches, and has attracted interest in both basic neuroscience and applied skin-biology research.
In dermatological research models, SNAP-8 has been explored in the context of skin-cell signalling and muscle-contraction-related pathways in facial tissue, where SNARE-complex activity is studied in relation to dynamic lines and expression-related changes at the tissue level.
myPEPT supplies SNAP-8 at ≥99% verified purity with a Certificate of Analysis from independent lab testing. Shipped across the EU in research-grade packaging.
What researchers should know: SNAP-8 is a research peptide supplied for laboratory use only. In this format it is not a finished cosmetic ingredient or therapeutic product. Handle and store it according to your institution's protocols for synthetic peptide research compounds.

Frequently asked
7 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
What is SNAP-8 as a research peptide?
SNAP-8 (Acetyl Octapeptide-3, sequence: Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2) is a synthetic octapeptide with a molecular weight of approximately 1,075 Da. It is studied in laboratory and in-vitro research for its competitive interaction with the SNARE complex formation assay. SNAP-8 is available from my\PEPT.eu for in-vitro research use only and has not been approved by any regulatory authority.
How should SNAP-8 be stored?
Lyophilized SNAP-8 should be stored at −20 °C in a sealed, light-protected vial. After dissolution in sterile buffer for laboratory assay use, keep at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles. Not for human or veterinary consumption.
