Epitalon vs MOTS-c
Epitalon is mainly studied for longevity, sleep, circadian rhythm. while MOTS-c is studied for metabolic efficiency, energy, body composition. The difference is in the mechanism and the evidence, not in which is "better": it depends on the goal.

How they differ
Although sometimes mentioned together, Epitalon and MOTS-c do not target the same thing. Epitalon: A peptide studied for its relationship with telomerase regulation and rhythms associated with cellular aging. MOTS-c: A mitochondrial-derived peptide studied for its relationship with metabolic efficiency, glucose homeostasis and cellular-energy signaling.

What is the main difference between Epitalon and MOTS-c?
Epitalon targets longevity, sleep, circadian rhythm. and MOTS-c targets metabolic efficiency, energy, body composition. They act through different pathways, so the choice depends on your goal, not on which is "stronger".
Can they be studied together?
Combinations are studied by goal in the literature, but combining is not just adding: it changes the safety profile. What to combine and how is decided with a professional; here we only explain what each is studied for.
Which has more human evidence?
Based on the references we verified, Epitalon has more human studies of this pair. Each one's evidence level is in the table above, and the references with their PMID are at the end.
