epitalon or epithalon mechanism of action telomerase Can 4 amino acids influence how we age? (Epithalon) is a synthetic tetrapeptide that has been studied for decades for its potential effects on activity, telomere biology, circadian rhythm regulation Epithalon Capsules | What Researchers

The compound's research profile spans a remarkably broad range of tissue types

Immune effects are restorative, not overstimulating: It rebalances T-cell ratios, upregulates IL-2 in aged tissues, and improves neuroimmune integration, suggesting a targeted recalibration of immune tone rather than indiscriminate boosting. It restores circadian and hormonal rhythms: By stimulating melatonin synthesis, protecting pineal structure, and re-entraining clock genes, Epitalon may counter the widespread circadian drift of aging, with implications far beyond sleep, touching immunity, metabolism, and neuroprotection
