Epithalon is one of the older ideas in longevity research and one of the least settled. It is a synthetic peptide of four amino acids, derived from a pineal-gland extract, and it is studied for its effect on telomerase and on the pineal signaling that governs circadian rhythm. It is also sold differently from everything else in the catalog: as a single month, without a subscription or 3-month option.
Promise offers injectable and nasal spray formats, both sold as a single month. A licensed provider reviews your health history and prescribes only when treatment is appropriate for you.
