Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. | | Mechanism of Action | FOXO4-DRI works by disrupting the protein-protein interaction between FOXO4 (Forkhead box O4) and p53 in senescent cells, which releases p53 from nuclear sequestration and allows it to translocate to the mitochondrial outer membrane where it triggers the… | 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 established in humans; no published human pharmacokinetic data. The D-retro-inverso construction confers resistance to human proteases, which in preclinical models extends the in vivo half-life from minutes (typical for comparable L-amino-acid peptides) to hours ([Baar et al., 2017](https://pubmed.ncbi.nlm.nih.gov/28340339/)). | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | | Typical Dose Range | No validated human dose. Self-report: 2-15 mg SC per dose (typically 5 mg), pulsed 3-7 days every 2-6 months; no human PK data. The 5 mg/kg figure seen in some sources is a mouse research dose (Baar 2017), not a human dose. | 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 | The side effect profile of FOXO4-DRI in humans is not documented because no clinical trials have been conducted. Rodent studies from the Baar et al. 2017 publication and subsequent work report generally acceptable tolerability at doses producing senolytic… | 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 | 5358.2 g/mol (Methods, PMID: 28340339) | Free peptide (GHK): 340.38 Da (C14H24N6O4).

FOXO4-DRI is a recovery that foxo4-dri works by disrupting the protein-protein interaction between foxo4 (forkhead box o4) and p53 in senescent cells, which releases p53 from nuclear sequestration and allows…. 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 established in humans; no published human pharmacokinetic data. The D-retro-inverso construction confers resistance to human proteases, which in preclinical models extends the in vivo half-life from minutes (typical for comparable L-amino-acid peptides) to hours ([Baar et al., 2017](https://pubmed.ncbi.nlm.nih.gov/28340339/)). vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range. ### Which has the longer half-life, FOXO4-DRI or GHK-Cu? FOXO4-DRI has a half-life of Not established in humans; no published human pharmacokinetic data. The D-retro-inverso construction confers resistance to human proteases, which in preclinical models extends the in vivo half-life from minutes (typical for comparable L-amino-acid peptides) to hours ([Baar et al., 2017](https://pubmed.ncbi.nlm.nih.gov/28340339/)).. 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. ### Which is cheaper, FOXO4-DRI or GHK-Cu? Lowest listed price on BodyHackGuide: FOXO4-DRI from $99.99, GHK-Cu from $34.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack FOXO4-DRI and GHK-Cu? Stacking depends on mechanism overlap, safety profile, and goals. FOXO4-DRI and GHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
