Snap-8 10mg (10 Vials / Kit)

Snap-8 at a glance

Known by its cosmetic ingredient name acetyl octapeptide-3, Snap-8 was built by lengthening the Argireline hexapeptide with two more amino acids at the C-terminal end. Both sequences are modeled on the N-terminal portion of SNAP-25, a protein that nerve endings use to release neurotransmitters. Snap-8 belongs to the cosmetic-peptide category, studied in skin-care formulation science rather than in hormone or metabolic research, and it is offered as freeze-dried powder.

Price and availability

Sold by Uther Peptide and sent from China, this listing is a kit of 10 vials at 10mg each (100 mg in total). At $40.00 for the kit, that works out to $0.40 per mg. Across 5 brands listing Snap-8 here, the middle half of prices falls between $0.40 and $0.40 per mg; this kit is inside that range. As with every order here, the brand is paid only after you confirm delivery.

What it is studied for

Muscle contraction depends on nerve endings releasing acetylcholine, and that release requires the SNARE complex, a set of proteins including SNAP-25 that fuse vesicles with the cell membrane. Snap-8 is designed to resemble part of SNAP-25 and is proposed to compete for its place in the complex, making the assembly less efficient. In cell assays and cosmetic studies, this has been linked to reduced neurotransmitter release and to measurements of expression-line depth in topical formulations. The size of these effects, and how much peptide penetrates skin, remain debated.

Research and regulatory status

Research sits in dermatology and cosmetic science. Published and manufacturer studies use in vitro assays and topical formulations applied to the forehead or around the eyes, and many are small or industry-sponsored. Snap-8 is used as a cosmetic ingredient rather than regulated as a drug, and it has no approved medical use. It is often evaluated alongside Argireline and other SNARE-targeting peptides as comparators.

Checking the lab data

A credible report shows a mass spectrometry result matching the acetylated, amidated eight-residue sequence, which distinguishes Snap-8 from Argireline, the shorter hexapeptide with a lower mass. HPLC purity with the chromatogram and measured content are standard. For raw-powder listings intended for formulation work, a description of appearance and moisture content is useful, and the report should state whether the material is the free peptide or an acetate salt.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 10 mg vial dissolved in 2 mL gives 5 mg/mL, or 10 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
