Full Cardiogen profile (https://www.bodyhackguide.co/compound/cardiogen) ## 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 | Cardiogen | GHK-Cu | | --- | --- | --- | | Category | Recovery | 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 | Mechanism of Action Cardiogen's proposed mechanism is the Khavinson short-peptide bioregulator framework applied to cardiac tissue. The three-stage model - absorption and distribution, nuclear import, sequence-selective chromatin modulation - has been detailed… | 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 for copper-dependent enzymes like SOD1, lysyl oxidase, cytochrome c oxidase, and… | | Half-Life | Not characterized in humans. As a short linear tetrapeptide (Ala-Glu-Asp-Arg), Cardiogen is expected to undergo rapid enzymatic hydrolysis to its constituent amino acids; no validated modern pharmacokinetic half-life has been published. | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | | Typical Dose Range | 20 mg oral once daily x10 days, or 2-5 mg SC daily x10 days; 60-90 day washout | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) | | Dosing Frequency | — | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. | | Administration | — | Subcutaneous, Topical | | Side Effects | Side Effects and Safety Cardiogen has been used in Russian clinical settings and post-Soviet supplement channels for roughly 20 years without a substantial adverse-event literature. That absence is reassuring in direction but must be contextualised against the… | Topical GHK-Cu is generally well tolerated; higher-concentration formulations (4-5%) raise the odds of irritation, redness, or stinging. Injectable use has no safety data from controlled trials; the main theoretical concern is copper accumulation with repeated… | | Molecular Weight | 489.5 g/mol (C18H31N7O9, tetrapeptide Ala-Glu-Asp-Arg) | Free peptide (GHK): 340.38 Da (C14H24N6O4).

Cardiogen is a recovery that mechanism of action cardiogen's proposed mechanism is the khavinson short-peptide bioregulator framework applied to cardiac tissue. the three-stage model - absorption and…. 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 characterized in humans. As a short linear tetrapeptide (Ala-Glu-Asp-Arg), Cardiogen is expected to undergo rapid enzymatic hydrolysis to its constituent amino acids; no validated modern pharmacokinetic half-life has been published. vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range. ### Which has the longer half-life, Cardiogen or GHK-Cu? Cardiogen has a half-life of Not characterized in humans. As a short linear tetrapeptide (Ala-Glu-Asp-Arg), Cardiogen is expected to undergo rapid enzymatic hydrolysis to its constituent amino acids; no validated modern pharmacokinetic half-life has been published.. 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 Cardiogen and GHK-Cu? Stacking depends on mechanism overlap, safety profile, and goals. Cardiogen and GHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
