A copper peptide in Skin & appearance
GHK-Cu is glycyl-L-histidyl-L-lysine bound to copper. Research catalogs treat it as a copper peptide discussed around collagen and skin-appearance models. The GHK-Cu 100mg listing is a lyophilized research vial in Skin & appearance.
On the product page you'll see the research angles people usually look up: collagen, skin firmness, hair appearance, and scar repair. That's why it shows up in skin catalogs. Those lines describe why it shows up in skin catalogs.
The 100mg listing
One size: 100mg. Third-party tested. We don't print a lot code or purity figure on the product page. Supply, testing, and COA framing covers what a COA usually is versus what we publish on the storefront.
KLOW and the rest of the skin group
KLOW includes GHK-Cu plus KPV, BPC-157, and TB-500 in an 80mg blend. That is a different listing, not a larger GHK-Cu size. See What is KLOW?. AHK-Cu is a different copper peptide — see What is AHK-Cu? and GHK-Cu vs AHK-Cu. GLOW is a three-peptide blend without KPV — see What is GLOW? and KLOW vs GLOW. The same group also has KPV (What is KPV?), Glutathione (What is glutathione?) and MT-1 (What is MT-1?) — separate compounds, each with its own page.
