Epitalon is a synthetic tetrapeptide with anti-aging properties.1,2,3,4 Dietary administration of epitalon (0.00001% w/w) reduces levels of lipid peroxidation products in aged D. melanogaster tissue homogenates.

Epitalon (1 μg/animal) delays age-related estrous shutdown and decreases the frequency of bone marrow cell chromosomal aberrations in female mice.2 It decreases spontaneous mammary gland and ovarian tumor development and metastasis in aged female mice.3 Epitalon also stimulates melatonin synthesis and normalizes the circadian rhythm of cortisol secretion in senescent female M. mulatta monkeys.4
