| Attribute | FOXO4-DRI | NAC |
|---|---|---|
| Category | Recovery | Antioxidants |
| Research Stage | Preclinical | Preclinical |
| 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… | NAC's mechanism of action operates through at least four distinct but overlapping pathways, and understanding which pathway dominates in a given clinical context is essential for predicting whether supplementation will actually help. The four pathways are (1)… |
| 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/)). | — |
| 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. | — |

| 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… | NAC has one of the most favorable safety profiles in medicine when dosed appropriately and used for appropriate indications. Side effects are almost entirely gastrointestinal at oral therapeutic doses and anaphylactoid at high IV infusion rates; true allergic… |

Frequently asked
What's the difference between FOXO4-DRI and NAC?
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…. NAC is a antioxidants that nac's mechanism of action operates through at least four distinct but overlapping pathways, and understanding which pathway dominates in a given clinical context is essential for…. 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 not reported), and typical dose range.
Which has the longer half-life, FOXO4-DRI or NAC?
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/)).. NAC has a half-life of not reported. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Which is cheaper, FOXO4-DRI or NAC?
Lowest listed price on BodyHackGuide: FOXO4-DRI from $119.00, NAC from $49.99. 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 NAC?
Stacking depends on mechanism overlap, safety profile, and goals. FOXO4-DRI and NAC should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
