| Category | Longevity & Healthy Aging | Longevity & Healthy Aging |
| Best known for | Senolytic / senescent-cell clearance research | Telomerase activation research |
| Mechanism of action | Specialized senolytic. Targets and eliminates senescent ('zombie') cells causing inflammation. | Synthetic pineal peptide. Studied for telomerase activation, sleep regulation, endocrine normalization. |
| Human research | None | Limited |
| Animal research | Limited | Moderate |
| Mechanistic research | Preliminary | Emerging |
| Study cadence cited | Daily during the 5-day pulse | Daily during the cycle |
| In plain English | It blocks a 'don't die' signal in senescent cells so they undergo apoptosis instead of lingering. | Epitalon is the most-discussed 'longevity peptide.' Researchers study its effects on telomeres, the protective caps at the end of your chromosomes that shorten with age. |
| How it works | Disrupts the FOXO4-p53 interaction in senescent cells, freeing p53 to trigger apoptosis selectively in senescent (not healthy) cells. | Activates telomerase, increasing telomere length in research models. Also modulates melatonin production and circadian rhythm. |
| Researchers study | Aged mice, fibrosis, frailty, and chemotherapy-induced senescence. | Telomere biology, age-related decline, melatonin and sleep, and cancer-related markers. |
| Internet discussion | One of the most-hyped longevity peptides on biohacker forums. | Annual 'mini-cycles' are the popular protocol discussion. |
