The Longevity System

Mitochondrial & Longevity

The longevity and energy peptide category at Portal to Wellness covers the most researched compounds in cellular aging science. Compounds in this category are studied in telomere biology, mitochondrial function and NAD+ metabolism assays.

The core longevity compounds in this category:

Epithalon is a tetrapeptide (Ala-Glu-Asp-Gly) with a multi-decade research history originating in the work of Vladimir Khavinson at the St. Petersburg Institute of Bioregulation. Its primary studied mechanisms include telomerase activation — the enzyme responsible for elongating telomeres — and pineal gland regulation of melatonin.

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme in mitochondrial energy metabolism and the substrate for the sirtuin enzymes (SIRT1–7). PTW supplies direct NAD+ in 1,000 mg research vials.

MOTS-C is a mitochondrial-derived peptide that activates AMPK signaling and drives mitochondrial biogenesis. MOTS-c is a mitochondria-derived peptide studied for AMPK signalling in animal models.

SS-31 (Elamipretide) is studied for its interaction with the inner mitochondrial membrane, including cristae structure and electron transport chain function.

All PTW longevity compounds are independently third-party tested for purity and identity.

All compounds are supplied for scientific research purposes only and are not intended for human use.
