SS-31 is a mitochondrial peptides that ss-31's mechanism of action is distinctive among mitochondrial interventions because it exploits a fundamental physical property of the inner mitochondrial membrane - the high…. NAD+ is a longevity that redox cofactor function nad+ serves as the primary electron acceptor in catabolic reactions (glycolysis, tca cycle, fatty acid oxidation), cycling between its oxidized (nad+) and…. The two differ in mechanism, half-life (~2-4 hours (plasma, after subcutaneous injection); tissue residence is longer due to cardiolipin binding vs Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent), and typical dose range. ### Which has the longer half-life, SS-31 or NAD+? SS-31 has a half-life of ~2-4 hours (plasma, after subcutaneous injection); tissue residence is longer due to cardiolipin binding. NAD+ has a half-life of Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, SS-31 or NAD+? Lowest listed price on BodyHackGuide: SS-31 from $72.00, NAD+ from $25.00. 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 SS-31 and NAD+? Stacking depends on mechanism overlap, safety profile, and goals. SS-31 and NAD+ 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. ## See current vendor prices Listings from the vendors we track.
