Discover SNAP-8 dosage trends, reconstitution volumes, and vial size patterns from anonymized WPA peptide calculator sessions.
SNAP-8 (acetyl octapeptide-3) is an eight-amino acid analog of SNAP-25, a substrate of the SNARE complex involved in vesicle fusion and neurotransmitter release at the neuromuscular junction. By competitively inhibiting this complex, it is researched for its ability to reduce the appearance of expression lines and wrinkles. This data reveals the dose amounts, vial sizes, and diluent volumes researchers most commonly select when setting up their SNAP-8 reconstitution protocol.
SNAP-8 (also known as acetyl octapeptide-3, INCI name Acetyl Octapeptide-3) is an eight-amino acid synthetic peptide analog of SNAP-25 (synaptosomal-associated protein 25 kDa) — one of the three core proteins of the neuronal SNARE complex that mediates synaptic vesicle fusion and neurotransmitter release at the neuromuscular junction. The proposed mechanism is competitive inhibition of SNAP-25 within the SNARE complex: by occupying the SNAP-25 binding domain, SNAP-8 is proposed to reduce the rate of vesicle fusion and acetylcholine release at the junction of facial motor neurons and superficial facial muscles, attenuating the repetitive muscular contractions that drive dynamic wrinkle formation (expression lines).
SNAP-8 (acetyl octapeptide-3) is a topical cosmetic peptide used in anti-wrinkle skincare formulas, extending the better-known Argireline (acetyl hexapeptide-8) sequence by two residues. It is supplied as a solution or powder for topical formulation — not an injectable research peptide — so what matters is identity and the labeled peptide concentration.
SNAP-8 is marketed to interfere with SNARE-complex assembly at the neuromuscular junction, the same mechanistic premise as Argireline, aiming to reduce the muscle contractions behind expression lines. Evidence is limited to manufacturer and small cosmetic studies; it has not been characterized in peer-reviewed clinical trials to the standard of a drug.
Published evidence for SNAP-8 is limited to manufacturer data and small cosmetic-formulation studies rather than independent peer-reviewed trials. Treat anti-aging claims as cosmetic marketing, not established clinical results.
SNAP-8 has a reported half-life of n/a — used topically, and the dose intervals researchers model most often fall around applied topically (usually twice daily). SNAP-8 is a cosmetic peptide applied to the skin, not injected. Systemic absorption is minimal, so plasma half-life and buildup are not meaningful concepts for its use. It is catalogued under Skin Peptides on WPA.
13 SNAP-8 reconstitution calculations have been logged by the WPA community. The most common dose entered is 1mg (4 calculations). The most common bacteriostatic water volume is 3mL. The most popular vial size is 10mg (13 sessions).
