Full Hydroxytyrosol profile (https://www.bodyhackguide.co/compound/hydroxytyrosol) ## GHK-Cu GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a molecule Pickart and Thaler first pulled out of human plasma in 1973. The free peptide (GHK, C14H24N6O4) weighs about 340.4 Da; bind it 1:1… **Lowest listed price:** $34.99 across 7 listings Full GHK-Cu profile (https://www.bodyhackguide.co/compound/ghk-cu) ## Side-by-side comparison | Attribute | Hydroxytyrosol | GHK-Cu | | --- | --- | --- | | Category | Polyphenol | Skin, Hair & Aesthetics | | Research Stage | Preclinical | Approved/marketed as a topical cosmetic ingredient (Copper tripeptide-1) with supporting small human studies. Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. | | Mechanism of Action | Hydroxytyrosol's pharmacology organizes around six interlocking mechanisms that together explain the cardiovascular, metabolic, neuroprotective, and longevity signals attributed to olive polyphenol intake. (1) Direct antioxidant activity and LDL oxidation… | GHK-Cu works mostly as a copper shuttle and a signaling peptide.

Hydroxytyrosol is a polyphenol that hydroxytyrosol's pharmacology organizes around six interlocking mechanisms that together explain the cardiovascular, metabolic, neuroprotective, and longevity signals attributed to…. GHK-Cu is a skin, hair & aesthetics that ghk-cu works mostly as a copper shuttle and a signaling peptide. it binds cu(ii) with high affinity (log k around 16.4, close to albumin's 16.2) and can supply or regulate copper…. The two differ in mechanism, half-life (not reported vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range. ### Which has the longer half-life, Hydroxytyrosol or GHK-Cu? Hydroxytyrosol has a half-life of not reported. GHK-Cu has a half-life of ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Can you stack Hydroxytyrosol and GHK-Cu? Stacking depends on mechanism overlap, safety profile, and goals. Hydroxytyrosol and GHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
