Its proposed mechanism spans several parallel pathways. The human-relevant evidence is strongest for melatonin/circadian effects; the strongest laboratory evid… Half-Life Not well characterized in humans. As a small tetrapeptide, AEDG is expected to have a very short plasma half-life (on the order of minutes), while downstream gene-expression and circadian effects are thought to persist considerably longer. Any specific half-life figure should be treated as an unvalidated estimate. Dosing Once daily for 10–20 day cycles Dose Range 5000-10000 mcg (5-10 mg) subcutaneous daily for 10-20 day cycles; typically repeated 1-2 times per year in anti-aging protocols Routes Subcutaneous Common Vials 10mg 50mg Potential Benefits Telomerase activation and telomere elongation (human cell culture) Normalization of circadian melatonin rhythm (human data from epithalamin, the parent pineal preparation) Improved sleep consolidation and circadian regularity (subjective) Modest life-span effects in rodents (mainly maximum / late-survivor lifespan; no change in mean lifespan) Reduced incidence of specific tumors (e.g. ~6-fold fewer leukemias in SHR mice); no change in total tumor incidence Reduced chromosomal aberrations in aged rodent tissue Site-specific DNA / chromatin binding (proposed epigenetic modulation) Association with lower mortality in an elderly cardiovascular cohort (epithalamin RCT, Korkushko 2011) Safety Notes Common Injection site redness or mild irritation (subcutaneous administration) Mild drowsiness during evening administration (likely due to melatonin stimulation) Transient flushing reported anecdotally Serious No serious adverse events reported in published literature Long-term safety data limited to Russian bioregulation studies Theoretical concern about telomerase activation in pre-cancerous cells (though animal data shows tumor suppression, not promotion) No Western clinical trials conducted — all human data from Russian gerontological programs ### Mechanism of Action Epithalon (AEDG; Ala-Glu-Asp-Gly) is a synthetic tetrapeptide modeled on the pineal polypeptide preparation **epithalamin**. Its proposed mechanism spans several parallel pathways. The human-relevant evidence is strongest for melatonin/circadian effects; the strongest laboratory evidence is the telomerase work in human cell culture. **1. Telomerase activation and telomere elongation (human cell culture)** The most-cited finding is that Epithalon added to telomerase-negative human fetal fibroblasts induced expression of the telomerase catalytic subunit (hTERT), restored telomerase activity, and elongated telomeres ([PMID:12937682] - Khavinson, Bondarev & Butyugov, _Bull Exp Biol Med_, 2003). In a follow-up, fibroblasts that normally senesced at passage 34 underwent roughly 10 additional divisions (to passage ~44), overcoming the Hayflick limit, with telomeres re-lengthened toward early-passage size ([PMID:15455129] - Khavinson et al., _Bull Exp Biol Med_, 2004). These are in-vitro results in cultured cells; the peptide is not itself a telomerase enzyme and appears to de-repress the hTERT gene rather than encode it. (The figure often quoted online - a 33% telomere increase at 10 ng/mL over 10 days - is not stated in the primary papers and should not be treated as established.) **2. Melatonin restoration via pineal signalling** Epithalon derives from epithalamin, a pineal peptide preparation used in Soviet/Russian geriatric medicine since the 1970s. In a randomized controlled trial in elderly coronary patients, courses of **epithalamin** normalized the circadian rhythm of melatonin production and of carbohydrate/lipid metabolism ([PMID:22451889] - Korkushko, Khavinson et al., _Bull Exp Biol Med_, 2011). This melatonin/circadian normalization is the most plausible basis for the deeper, more consolidated sleep users report as the earliest subjective effect. Note that the human melatonin data derive chiefly from epithalamin (the parent preparation), not from the isolated AEDG tetrapeptide. **3. Site-specific DNA / chromatin binding (proposed epigenetic modulation)** Fluorescence and nuclear-penetration studies show AEDG enters the cell nucleus and binds single- and double-stranded DNA and deoxyribooligonucleotides in a sequence-specific manner, discriminating cytosine-methylation status and binding preferentially to CNG- and CAG-containing sequences ([PMID:22117547] - Fedoreyeva et al., _Biochemistry (Mosc)_, 2011). This site-specific binding is proposed as an epigenetic route by which short peptides could influence gene activity. (Earlier claims that AEDG specifically targets "ACATAC/ATTTC" promoter motifs are not supported by this work.) **4. Rodent life-span and tumor data - what it actually shows** The Anisimov/Khavinson group tested Epitalon in several mouse strains, and the real effects are modest. In outbred Swiss-derived SHR mice, Epitalon did **not** change mean life span; it increased the life span of the last 10% of survivors by ~13% and maximum life span by ~12%, reduced bone-marrow chromosome aberrations by ~17%, and did **not** change total spontaneous tumor incidence, though it suppressed leukemia roughly 6-fold ([PMID:14501183] - Anisimov et al., _Biogerontology_, 2003). In CBA mice, chronic dosing modestly prolonged life span with a reduction in spontaneous tumor incidence ([PMID:11227856] - Anisimov et al., _Ross Fiziol Zh_, 2001). In senescence-accelerated (SAM) mice it lengthened survival among the longest-lived animals without changing overall tumor frequency ([PMID:15909815] - Anisimov et al., _Vopr Onkol_, 2005). These are genuine but modest, tail-of-survival effects - not the "~30% life-span extension" or "tumor incidence 44%23%" figures that circulate in vendor copy. **What epithalon does NOT do** - It is not a growth-hormone secretagogue and does not raise IGF-1 or drive muscle accretion (contrast CJC-1295/Ipamorelin). - It has no FDA- or EMA-approved indication, and Western human evidence is limited. - Its telomerase effect is promoter-level de-repression in cell culture, not a demonstrated systemic anti-aging effect in humans. ### Overview Epithalon (also spelled **Epitalon**, sequence **Ala-Glu-Asp-Gly / AEDG**) is a synthetic tetrapeptide designed by Prof. Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology in the 1980s as a short-chain analog of **epithalamin**, a peptide extract of bovine pineal gland. It is the most-studied "longevity peptide" in the Russian peer-reviewed literature, with over 30 years of published work on **telomerase activation, telomere lengthening, melatonin restoration, and life-span extension in rodents**. The core biology is three-fold: - **Telomerase activation in somatic cells** — Khavinson and Smirnova showed that 10 ng/mL AEDG increased hTERT expression and telomerase activity in human somatic fibroblasts, extending proliferative capacity by ~42% over the Hayflick limit ([Khavinson et al., 2003, _Bull Exp Biol Med_]). - **Restoration of pineal melatonin secretion** — In aged rats and in elderly humans, epithalon restored the nocturnal melatonin peak that declines with pineal calcification, improving circadian amplitude and sleep architecture ([Anisimov et al., 2003]). - **Direct chromatin binding (epigenetic)** — NMR and X-ray studies demonstrate that AEDG binds the major groove of DNA at specific sequences, modulating transcription of interferon-γ, hTERT, and cell-cycle regulators ([Fedoreyeva et al., 2011]). **Critical evidence-quality caveat:** Unlike BPC-157 or the GLP-1 agonists, the **human clinical evidence for Epithalon is almost entirely from Russian-language publications** from a single research consortium (Khavinson / Anisimov / Korkushko). Western replication is minimal. The rodent data are compelling — a **~30% median life-span extension** in female mice ([Anisimov et al., 2003]) — but translating this to human longevity remains hypothesis rather than demonstrated fact. Epithalon is used in biohacking communities for: - Sleep consolidation in adults over 40 (melatonin restoration) - Telomere preservation as part of a longevity stack - Circadian rhythm repair after shift-work or jet lag - Adjunct in age-related immunosenescence It is delivered by subcutaneous injection, typically **5-10 mg/day for 10-20 consecutive days**, followed by a **3-6 month washout**. This intermittent pulsing is intentional — Khavinson's protocols were always short-cycle, never continuous — and is a key safety feature in the absence of long-term continuous-dosing data. ### Potential Research Fields Longevity / anti-aging Telomere biology Chronobiology / sleep Pineal endocrinology Geroscience Epigenetics Cancer prevention (rodent) Immunosenescence ## Chemical Information IUPAC Name L-alanyl-L-alpha-glutamyl-L-alpha-aspartylglycine CAS Number 307297-39-8 Molecular Formula C14H22N4O9 Molecular Mass 390.35 g/mol Image: Epithalon molecular structure (https://pubchem.ncbi.nlm.nih.gov/rest/pug/compound/cid/219042/PNG?image_size=300x300) View on PubChem: https://pubchem.ncbi.nlm.nih.gov/compound/219042 Amino Acid Sequence Ala-Glu-Asp-Gly (AEDG) ## Dosing & Protocols ### Unlock the dosing protocols Enter your email to keep reading.

Not intended as medical advice. Consult a healthcare professional before use. ## Frequently Asked Questions How strong is the human evidence for epithalon's longevity claims? The rodent data is real but modest: across SHR, CBA and SAM mouse strains, Epitalon mainly extended maximum and late-survivor lifespan (roughly 10-13% in the last 10% of survivors) rather than mean lifespan, reduced certain tumors (about 6-fold fewer leukemias in SHR mice) without lowering total tumor incidence, and cut chromosome aberrations - it did not produce the ~30% lifespan jumps sometimes claimed online. The human data are almost entirely from one Russian/Ukrainian group and largely use epithalamin (the parent pineal preparation), not the isolated AEDG tetrapeptide; the most-cited is a randomized controlled study in elderly coronary patients (Korkushko/Khavinson 2011) reporting decelerated cardiovascular aging, normalized melatonin rhythm and significantly lower mortality. No Western double-blind RCT exists. Treat epithalon as plausible-but-unproven for human longevity endpoints, and at best suggestive for sleep and melatonin support in older adults. Will I notice anything during my first cycle? The most reliable subjective effect is deeper, more consolidated sleep starting around night 3-5 of a cycle. Many users report more vivid dreams in the first week (consistent with restored REM pressure from melatonin rise). Energy and mood improvements in the day typically lag sleep changes by a week or so. If you are under 40 with already-good sleep, the effect may be subtle. If you are over 50 with age-related sleep fragmentation, the effect is usually obvious by the end of week 2. How often should I cycle epithalon? Standard Russian protocol: 10-20 consecutive days, then a minimum of 3 months off. Most biohackers run 1-2 cycles per year separated by ~6 months. The most-cited elderly trial (Korkushko/Khavinson) actually used the parent preparation epithalamin as 6 courses over 3 years with long-term follow-up, not continuous dosing. Continuous daily dosing is not evidenced and is contrary to every published protocol; the pulsed pattern is thought to matter, letting the pineal axis re-regulate rather than downregulate under sustained stimulation. Is epithalon safe for someone with a history of cancer? It is an absolute contraindication during active malignancy and a relative contraindication for at least 5 years after hormone-sensitive cancer (breast, prostate, endometrial). The mechanism - hTERT upregulation via promoter demethylation - is theoretically pro-tumorigenic, even though rodent data paradoxically show reduced incidence of certain tumors (possibly via immune rejuvenation). Without human data to stratify this risk, the conservative approach is to avoid. Survivors of long-remission non-hormone-sensitive cancers should discuss individually with an oncologist. Can I take epithalon orally instead of injection? Oral bioavailability is essentially zero. AEDG is a short peptide rapidly hydrolyzed by gastric and intestinal proteases. Sublingual formulations exist in some vendor catalogs but lack published bioavailability data and no human trial has used them. All published clinical and preclinical protocols use subcutaneous or intramuscular injection. If you cannot or will not inject, epithalon is not a practical option for you - this is a peptide where delivery matters. What is the difference between epithalon and epithalamin? Epithalamin is the crude bovine pineal extract used in Soviet/Russian geriatric medicine from the 1970s onward - a mixture of many pineal peptides. Epithalon (AEDG) is the synthetic four-amino-acid tetrapeptide that Khavinson identified as the active fragment. Epithalon is purer, more consistent, and easier to dose; epithalamin is rarely used today outside specific Russian clinical contexts. When biohackers say 'epithalon,' they almost always mean the synthetic tetrapeptide. Can I stack epithalon with other peptides like BPC-157 or CJC-1295? Yes, with two caveats. First, isolate variables in your first epithalon cycle - you want to know what epithalon does to your sleep before introducing another variable. Second, combining with a GH secretagogue (CJC-1295, ipamorelin) or healing peptide (BPC-157) has no documented pharmacologic interaction but lacks controlled safety data in combination. Most users run epithalon as a twice-yearly standalone cycle and use other peptides continuously in the intervening months. See our Peptide Stacking Guide (https://www.bodyhackguide.co/blog/peptide-stacking-protocols) for structured combinations. Do I need a telomere length test to benefit from epithalon? No. Telomere length assays (Life Length, Telomere Diagnostics, SpectraCell) have significant methodological variability - same-day duplicate samples can differ 10-20% - and no clinical guideline supports using them to make peptide decisions. If you want to track telomere length for curiosity or longitudinal self-quantification, do it consistently with the same lab and same assay; expect noisy data. The best proximate biomarker for whether epithalon is working for you is objective sleep data (deep sleep minutes, HRV, sleep efficiency) from an Oura or Whoop. Why is epithalon not FDA-approved if the data is so strong in Russia? Three reasons. First, the bulk of the human data is in Russian-language journals not indexed in Western regulatory databases, and translation quality and study methodology vary. Second, there has been no pharmaceutical sponsor willing to fund a registrational-quality Phase 3 program - the molecule is off-patent and commercial incentive is limited. Third, longevity endpoints are inherently long-duration and expensive to test. The result is a peptide with 30+ years of research use in Russia but research-only status in the US and EU. This is why vendor-grade material should always be sourced with a valid COA and handled as a research chemical. ## Research Tools ### Peptide Calculator Reconstitution & syringe units https://www.bodyhackguide.co/tools/reconstitution ### Reconstitution Guide How to mix, step by step https://www.bodyhackguide.co/guides/how-to-reconstitute-peptides ### Nasal Spray Calc mL per actuation https://www.bodyhackguide.co/tools/intranasal ### Half-Life Visualizer Decay curves https://www.bodyhackguide.co/tools/halflife ## Related Compounds ### MOTS-c Longevity & Cellular Health Preclinical ## Side-by-Side Comparisons Compare Epithalon head-to-head: mechanism, half-life, dosing, safety, and vendor prices.

Its proposed mechanism spans several parallel pathways. The human-relevant evidence is strongest for melatonin/circadian effects; the strongest laboratory evidence is the telomerase work in human cell culture. Telomerase activation and telomere elongation (human cell culture) The most-cited finding is that Epithalon added to telomerase-negative human fetal fibroblasts induced expression of the telomerase catalytic subunit (hTERT), restored telomerase activity, and elongated telomeres ([PMID:12937682] - Khavinson, Bondarev & Butyugov, Bull Exp Biol Med, 2003). In a follow-up, fibroblasts that normally senesced at passage 34 underwent roughly 10 additional divisions (to passage ~44), overcoming the Hayflick limit, with telomeres re-lengthened toward early-passage size ([PMID:15455129] - Khavinson et al., Bull Exp Biol Med, 2004). These are in-vitro results in cultured cells; the peptide is not itself a telomerase enzyme and appears to de-repress the hTERT gene rather than encode it. (The figure often quoted online - a 33% telomere increase at 10 ng/mL over 10 days - is not stated in the primary papers and should not be treated as established.) Melatonin restoration via pineal signalling Epithalon derives from epithalamin, a pineal peptide preparation used in Soviet/Russian geriatric medicine since the 1970s. In a randomized controlled trial in elderly coronary patients, courses of epithalamin normalized the circadian rhythm of melatonin production and of carbohydrate/lipid metabolism ([PMID:22451889] - Korkushko, Khavinson et al., Bull Exp Biol Med, 2011). This melatonin/circadian normalization is the most plausible basis for the deeper, more consolidated sleep users report as the earliest subjective effect. Note that the human melatonin data derive chiefly from epithalamin (the parent preparation), not from the isolated AEDG tetrapeptide. Site-specific DNA / chromatin binding (proposed epigenetic modulation) Fluorescence and nuclear-penetration studies show AEDG enters the cell nucleus and binds single- and double-stranded DNA and deoxyribooligonucleotides in a sequence-specific manner, discriminating cytosine-methylation status and binding preferentially to CNG- and CAG-containing sequences ([PMID:22117547] - Fedoreyeva et al., Biochemistry (Mosc), 2011). This site-specific binding is proposed as an epigenetic route by which short peptides could influence gene activity. (Earlier claims that AEDG specifically targets \"ACATAC/ATTTC\" promoter motifs are not supported by this work.) Rodent life-span and tumor data - what it actually shows The Anisimov/Khavinson group tested Epitalon in several mouse strains, and the real effects are modest. In outbred Swiss-derived SHR mice, Epitalon did not change mean life span; it increased the life span of the last 10% of survivors by ~13% and maximum life span by ~12%, reduced bone-marrow chromosome aberrations by ~17%, and did not change total spontaneous tumor incidence, though it suppressed leukemia roughly 6-fold ([PMID:14501183] - Anisimov et al., Biogerontology, 2003). In CBA mice, chronic dosing modestly prolonged life span with a reduction in spontaneous tumor incidence ([PMID:11227856] - Anisimov et al., Ross Fiziol Zh, 2001). In senescence-accelerated (SAM) mice it lengthened survival among the longest-lived animals without changing overall tumor frequency ([PMID:15909815] - Anisimov et al., Vopr Onkol, 2005). These are genuine but modest, tail-of-survival effects - not the \"~30% life-span extension\" or \"tumor incidence 44%23%\" figures that circulate in vendor copy. What epithalon does NOT do It is not a growth-hormone secretagogue and does not raise IGF-1 or drive muscle accretion (contrast CJC-1295/Ipamorelin). It has no FDA- or EMA-approved indication, and Western human evidence is limited. Its telomerase effect is promoter-level de-repression in cell culture, not a demonstrated systemic anti-aging effect in humans.", "dosageForm": "vial, capsule", "legalStatus": "Not approved for human use (research chemical)", "warning": "For research purposes only.
