Epithalon (Ala-Glu-Asp-Gly) is a tetrapeptide discovered by Dr. Vladimir Khavinson with 30+ years of human study data — the most research-backed longevity peptide in existence. It activates telomerase to rebuild telomere length, regulates melatonin, and delivers epigenetic anti-aging effects at the cellular level. Prescribed online from $185/cycle.
Start Your Epithalon Protocol →Epithalon (also spelled Epitalon) is a synthetic tetrapeptide consisting of four amino acids: Alanine-Glutamic acid-Aspartic acid-Glycine (Ala-Glu-Asp-Gly). It was discovered and extensively studied by Dr. Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology — one of the world's leading longevity research centers. With over 30 years of published research including human clinical trials, Epithalon has more real-world data behind it than virtually any other longevity peptide.
Epithalon's primary mechanism of action is the activation of telomerase — the enzyme responsible for maintaining and rebuilding telomeres. Telomeres are the protective caps at the ends of chromosomes, similar to the plastic tips on shoelaces. Each time a cell divides, telomeres shorten slightly. When they become too short, the cell can no longer divide and enters senescence (cellular "old age") or apoptosis (death). Telomere shortening is now recognized as one of the primary drivers of biological aging. By activating telomerase, Epithalon can slow — and in some cases reverse — telomere attrition, effectively extending cellular lifespan.
Beyond telomerase, Epithalon regulates the pineal gland's production of melatonin, normalizes circadian rhythms disrupted by aging, provides significant antioxidant protection, and has demonstrated anti-tumor activity in multiple studies. View all longevity protocols →
Directly activates telomerase — the cellular enzyme that rebuilds telomere length. This extends the replicative lifespan of cells and counters one of the primary molecular mechanisms of aging.
Modulates gene expression patterns associated with aging, restoring more youthful patterns of cellular behavior without altering underlying DNA sequence.
Regulates the epiphyseal (pineal) gland's production of melatonin. Restores circadian rhythm disruptions common in aging, improving sleep quality and hormonal regulation.
Reduces oxidative stress and lipid peroxidation — key drivers of cellular damage and accelerated aging. Protects DNA integrity and mitochondrial function.
Epithalon works at the deepest level of biology — the genome itself — to slow and reverse the cellular markers of aging.
Epithalon is ideal for anyone focused on longevity optimization, biological age reduction, and cellular health maintenance. It is particularly relevant for individuals over 40 who are proactively addressing aging, those with a family history of age-related diseases, executives and high-performers seeking cognitive and physical resilience, and anyone interested in measurable epigenetic age metrics.
Because Epithalon works at the cellular and genetic level rather than through a single symptom-based mechanism, its effects are comprehensive and systemic. Unlike treatments that address aging's symptoms (wrinkles, fatigue, low libido), Epithalon targets the underlying cellular processes that cause aging in the first place. It is the cornerstone of a serious longevity protocol and pairs powerfully with NAD+, Sermorelin, and MOTS-C for a comprehensive anti-aging stack.
Epithalon uses a cyclical protocol — short intensive cycles repeated 2–4 times per year for optimal telomerase activation.
| Protocol | Dose | Duration |
|---|---|---|
| Standard Cycle | 5 mg/day SubQ | 10–20 days, 2–4 times/year |
| Intensive Protocol | 5–10 mg/day SubQ | 20 days, 2x/year |
| Annual Protocol (4 cycles) | 5 mg/day SubQ | 10 days per cycle, quarterly |
* Epithalon is most effective used cyclically. Research protocols typically use 10mg total per 10-day cycle or 50mg total over a 20-day intensive cycle. Your licensed provider will establish your specific protocol.
Many patients notice improved sleep quality and circadian rhythm normalization within the first cycle. Reduced fatigue and improved mood are common early indicators.
Energy levels improve and cognitive clarity often sharpens. Antioxidant effects begin protecting cellular DNA. Early epigenetic changes begin at the cellular level.
Telomerase activation and telomere effects accumulate. Measurable improvements in biological aging markers. Physical resilience, recovery, and immune regulation improve.
Research shows significant anti-aging effects with annual cycling protocols. Long-term users report sustained energy, cognitive function, and measurable epigenetic age improvements.
Epithalon is priced per cycle. No hidden fees — provider consultation, prescription, and compounded medication included.
