Description
Acetyl Hexapeptide-8 (often marketed as Argireline®) is a synthetic hexapeptide (sequence: Ac-Glu-Glu-Met-Gln-Arg-Arg-NH₂) designed to mimic a fragment of SNAP-25 and modulate neurotransmitter release. By competing for SNARE-complex binding, it can help inhibit muscle micro-contractions—resulting in reduced appearance of dynamic wrinkles and fine lines. Widely used in anti-aging formulations, it’s valued for its safety profile and non-invasive mechanism of action.

Research & Clinical Studies
Anti-Wrinkle Efficacy
-
Blanes-Mira et al. (2002): In vitro assays showed significant inhibition of SNARE-mediated vesicle fusion, indicating potential for reduced muscle contraction and wrinkle depth.<sup>1</sup>
-
Randomized Placebo-Controlled Trial (2013): Topical application in human subjects over 8 weeks reduced forehead wrinkle depth by up to 30% with no reported adverse effects.<sup>2</sup>
Mechanistic Insights
-
Autophagy & Collagen Synthesis: Emerging studies suggest that Argireline may also upregulate collagen III expression, improving skin elasticity over prolonged use.<sup>3</sup>

FAQ
1. What are research peptides?
Research peptides are short chains of amino acids used in scientific and medical research. They are not approved for human consumption or therapeutic use but are studied for their potential biological effects.
2. Is Reverse Peptides a trusted source for buying peptides online?
Yes. Reverse Peptides offers 99% purity, third-party tested, and USA-made peptides. Our products are backed by quality assurance and a loyal base of researchers
3. How do I store research peptides after receiving them?
Most peptides should be stored in a cool, dry place. Lyophilized powders are typically stable at room temperature but should be refrigerated for long-term storage. Always refer to the product label.
4. What payment methods do you accept?
We accept major credit/debit cards and secure online payment options. All transactions are encrypted and secure.
5. Is a prescription required to purchase peptides from Reverse Peptides?
No. Since our peptides are sold strictly for laboratory research purposes, no prescription is required. However, buyers must be qualified researchers or institutions.
