What is GHK-Cu and what is SNAP-8?
GHK-Cu is classified as Copper-binding tripeptide · dermal & remodeling research; SNAP-8 as Synthetic acetylated octapeptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
GHK-Cu
Copper-binding tripeptide · dermal & remodeling research
GHK-Cu is a copper-binding tripeptide, glycyl-L-histidyl-L-lysine complexed with copper(II), that occurs naturally in human plasma. Verve supplies it as a high-purity research compound for dermal and tissue-remodeling research.
full GHK-Cu profile →SNAP-8
Synthetic acetylated octapeptide
SNAP-8 is a synthetic acetylated octapeptide, an elongated analog of acetyl hexapeptide-3 (Argireline) extended by two additional residues. Its sequence is modeled on the N-terminal region of SNAP-25, one of the proteins that assembles the SNARE complex, which makes it a convenient synthetic tool for studying that assembly in vitro.
