Anti-Aging Genetics & Natural Compounds
A comprehensive guide to the six key genetic pathways that control human aging, and the peptides, supplements, and foods that interact with each one. From telomeres to Yamanaka factors — the science of staying young.
The Chromosome Clock
At the ends of every chromosome are protective caps called telomeres. Every time a cell divides, its telomeres get shorter. When they become too short, the cell stops dividing and enters senescence, driving tissue aging and degradation.
Genetic Mechanism
- 1Telomeres are repetitive DNA sequences (TTAGGG) that protect chromosome ends from degradation
- 2Each cell division shortens telomeres by 50-200 base pairs
- 3When critically short, cells enter senescence or apoptosis
- 4The TERT gene encodes telomerase, an enzyme that rebuilds and lengthens telomeres
- 5TERT also acts as a transcription factor affecting expression of many anti-aging genes (2024 MD Anderson study)
- 6Telomerase is naturally active in stem cells and reproductive cells but silenced in most adult cells
Connected Peptides
Epitalon
Mechanism: Tetrapeptide (Ala-Glu-Asp-Gly) that directly activates telomerase enzyme expression
Evidence: 2025 study confirmed Epitalon increases telomere length in human cell lines through telomerase upregulation
Dosing: 5-10mg daily, subcutaneous injection, 10-20 day cycles
GHK-Cu
Mechanism: Upregulates 32% of human genes including DNA repair pathways that protect telomeres from oxidative damage
Evidence: Pickart et al. (2018) showed GHK-Cu resets gene expression toward youthful patterns across 4,000+ genes
Dosing: 1-2mg daily, subcutaneous injection

Curcumin reduces inflammation that accelerates telomere shortening
The Longevity Genes
Often dubbed "longevity genes," this family of seven genes (especially SIRT1 and SIRT6) helps repair DNA damage, manage inflammation, and maintain cellular metabolism. They are NAD+ dependent enzymes that mimic the benefits of caloric restriction.
The Centenarian Gene
One of the few genes consistently linked to humans who live to be 100 or older. FOXO3 helps regulate the body's response to stress and clears out damaged cellular components through autophagy.
The Growth vs. Longevity Switch
mTOR (mechanistic Target of Rapamycin) is a master growth switch. When active, it promotes cell growth and protein synthesis. When inhibited, it activates autophagy — the cellular cleanup process that removes damaged components and extends lifespan.
The Anti-Aging Hormone
Named after the Greek goddess who spins the thread of life, the Klotho gene produces a hormone that declines with age. Higher Klotho levels are associated with longer lifespan, better cognitive function, and reduced age-related diseases.
Cellular Reprogramming
In 2006, Shinya Yamanaka discovered four genes (Oct4, Sox2, Klf4, c-Myc) that can reprogram adult cells back to a stem cell-like state. Partial reprogramming — activating these factors briefly — can reverse cellular aging without losing cell identity.
Latest Anti-Aging Research
Peer-reviewed findings, automatically curated and reviewed
Human lifespan gains ~3 months per year. Someone born today has a 50/50 chance of reaching 100. The first person to live to 150 may already be alive.
TERT, in addition to telomere synthesis, functions as a transcriptional co-regulator for genes involved in aging and age-related diseases, influencing cellular senescence and inflammation.
Telomere attrition is identified as a key molecular mechanism contributing to the complex process of aging and its associated diseases.
A new compound activates TERT, leading to increased telomere synthesis, reduced cellular senescence, decreased inflammation, and alleviated neuroinflammation in aged models.
All findings are sourced from peer-reviewed literature and reviewed before publication.
