Epithalon vs MOTS-c

Overview

Epithalon and MOTS-c represent two different approaches to longevity research. Epithalon is a synthetic tetrapeptide proposed to activate telomerase, while MOTS-c is a mitochondrial-derived peptide involved in metabolic regulation. Neither is approved for clinical use, and both have limited human data.

This comparison is relevant because both peptides are discussed in longevity and anti-aging research contexts, but they work through fundamentally different biological pathways.
