Direct answer
Ginsenoside Rg3 can be sold in the United States as a supplement or cosmetic ingredient, classified as "Sold as a dietary supplement". That is not drug approval: FDA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What Ginsenoside Rg3 is
A ginseng saponin whose effect on senescence runs in both directions depending on the cell: it reversed replicative senescence in human fibroblasts in culture and is studied as a senescence inducer in tumour cells. The only human data are pharmacokinetic.
Ginsenoside Rg3 is a triterpenoid saponin from Panax ginseng, studied mainly in China and Korea. Its senescence literature is cell culture.
Mechanism: In cultured human fibroblasts, 20(S)-Rg3 restored ATP and the NAD+ to NADH ratio, downregulated PI3K and Akt through mTOR inhibition with p53 and p21 involvement, and activated sirtuin 3 and PGC1alpha to stimulate mitochondrial biogenesis; the 20(R) stereoisomer did not. In astrocyte culture, Rg3 suppressed interleukin 6 and interleukin 8 via NF-kappaB and p38 MAPK, a senomorphic action.
Regulatory history: Not approved for any indication in the United States. Sold as a ginseng-derived supplement ingredient. No senescence or ageing trial is registered.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
