    "problem_addressed": "Aging, age-related diseases, telomere shortening, loss of fertility and endocrine dysregulation",
    "concept_summary": "Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) that, when administered by injection, nasal spray or transdermal route, stimulates telomerase activity, elongates telomeres, restores melatonin and circadian rhythms, and exerts broad endocrine, antioxidant and anti-inflammatory effects. Reported outcomes include restored fertility in aged mice, increased lifespan in rats, reduced mortality in elderly humans, and improved organ function.",
