Overview
A 30 mL research serum combining GHK-Cu (copper tripeptide) with Snap-8 (acetyl octapeptide-3), an eight-amino-acid peptide derived from the N-terminal of the SNAP-25 protein. Supplied for in-vitro skin-model and formulation research where the two peptides are studied together.
Research background
GHK-Cu has a substantial in-vitro literature in fibroblast and extracellular-matrix research. Snap-8 (acetyl octapeptide-3) is studied as a SNARE-complex mimetic peptide: in cell-based assays it competes with SNAP-25 for a position in the complex that mediates vesicle release. The two are frequently combined in formulation research because they are examined for different endpoints in the same reconstructed-skin models. Data for both are predominantly in-vitro.
