Hot Selling SNAP-8 Peptide CAS 868844-74-0 99% White Lyophilized Powder For Laboratory Research

SNAP‑8 (Acetyl Octapeptide‑3) is a synthetic N‑terminal acetylated octapeptide, an extended analog of Acetyl Hexapeptide‑8. It mimics the N‑terminal fragment of SNAP‑25 protein. It is applied in pre‑clinical lab studies for SNARE‑complex interaction research, neurotransmitter release mechanism, neuromuscular junction biology, cosmeceutical peptide screening and peptide‑protein interaction evaluation.

Our SNAP‑8 is white lyophilized powder. Each batch undergoes strict HPLC and mass spectrometry testing to ensure purity above 99%. Relevant test documents can be provided upon customer request.

Mainly Benefits：

1. Relieve dynamic expression wrinkles
It interferes with the assembly of SNARE‑complex, reduces acetylcholine release at neuromuscular junctions and eases excessive contraction of facial expression muscles. It improves expression‑related lines such as forehead lines, glabellar lines and crow’s feet, while showing limited effect on deep static wrinkles.

2. Refine skin texture
Long‑term application helps smooth skin texture, keeps skin in a relaxed condition and alleviates roughness caused by repeated facial movements.

3. Mild anti‑wrinkle and good compatibility
Compared with acetyl hexapeptide‑8, it has stronger binding affinity. It is mild for most skin types and can be compounded with other skincare peptides.

Notice❗: For laboratory research use only, not for human or animal therapeutic use.
