Longevity
Longevity covers 3 compounds on WikiPep: Glutathione, NAD+ and SS-31. Across them, 6 of the 18 uses listed here have been studied in human trials of that compound.
SS-31 (elamipretide) is FDA-approved as Forzinity, for one rare condition, Barth syndrome, at a dose far above the figures research sites describe. Glutathione and NAD+ are not approved drugs. Most of the human studies here used a different route from the injections in the dosage guidelines: oral glutathione and intravenous NAD+.

Each one, in plain words
- Glutathione: Glutathione is a small molecule every cell makes, and the most common antioxidant inside cells. It is not an FDA-approved drug.
- NAD+: NAD+ is a helper molecule in every cell, needed to turn food into energy. It is not a peptide.
- SS-31: SS-31 (elamipretide) is a small peptide that goes straight to the mitochondria, the parts of cells that make energy. In 2025 the FDA approved it as Forzinity for Barth syndrome, a rare inherited condition.
