Which one should you choose?

Epitalon is better for deep cellular aging (telomeres and sleep), while MOTS-c is better for metabolic aging (energy and insulin). Epitalon works in the pineal gland to dramatically upregulate melatonin production and has been shown to lengthen telomeres, fundamentally extending cellular lifespan. MOTS-c works in the mitochondria to activate AMPK, restoring youthful energy metabolism and exercise capacity. Choose Epitalon (typically run twice a year) to improve circadian rhythms and target genetic aging. Choose MOTS-c to improve daily energy, insulin sensitivity, and athletic performance. They target completely different pillars of longevity.
