- 21:00 melatonin
- 12 ± 3 → 25 ± 4 pg/mLSaline: 12 ± 3 → 11 ± 3 pg/mLp<0.05 versus baseline and post-treatment saline
- Preserved baseline pineal function
- No melatonin change in 3 Epitalon recipients
In older adults with low baseline melatonin, Epitalon increased 03:00 plasma melatonin from 20 ± 4 to 49 ± 7 pg/mL; saline changed from 27 ± 4 to 25 ± 4. Evening melatonin also rose, while daytime concentrations did not change significantly.
Study notes · methods, sources and limitations
Participants or model 40 older intervention participants: 15 Epitalon, 15 Epithalamin and 10 saline; 10 young references. Baseline survey separately included 49 older and 15 younger people.
Important limitations
- The Epitalon low-melatonin comparison contains 12 treated and 8 saline recipients; the three Epitalon recipients with preserved function showed no change. These are hormone measurements, not demonstrated sleep improvement or lifespan extension. Human and monkey results are separate.

Study notes · methods, sources and limitations
Participants or model 162 patients (324 eyes), ages 18–72, examined; the report identifies 46 control patients (92 eyes).
Important limitations
- Allocation and masking are not described sufficiently to establish a randomized trial. Percentages refer to different outcomes and sometimes eyes; they are not one common response measure. The methods state 162 patients examined and 46 controls; do not describe 162 as the treated-arm size. The paper reports 18 eyes as 7.6%, a denominator not fully reconciled in the text. Retinal-disease findings do not demonstrate healthy-person vision enhancement or longevity.

What is Epitalon (Epithalon)?
Names in this research collection
AEDG · Epithalon
A synthetic four-amino-acid peptide, also called AEDG, developed from pineal-gland peptide research. It is distinct from the tissue extract Epithalamin.
Identity / background source ↗
Research background
Synthetic AEDG has direct human hormone and retinal findings. Long-term Epithalamin mortality studies concern the extract and are kept separate.
Epitalon (Epithalon): what the evidence shows
Epitalon, also spelled Epithalon, is the synthetic AEDG tetrapeptide. Human hormone studies and cell-level telomere findings are relevant research leads, but they do not establish human lifespan extension.
Curated by Molekul / @PepMariner. This guide summarizes linked source records; it is not an independent clinical review. Each source states what was inspected.
Human melatonin: a small subgroup comparison
In the low-melatonin subgroup of a 2007 report, 03:00 melatonin rose from 20 ± 4 to 49 ± 7 pg/mL in 12 Epitalon recipients; eight saline recipients changed from 27 ± 4 to 25 ± 4. Three Epitalon recipients with preserved baseline function showed no change. Hormone changes are not measured sleep improvement.
Telomeres: cells, with a published correction
The 2025 cell-line study reported telomere extension through telomerase-related changes in normal cells and alternative lengthening of telomeres in cancer cell lines. Figures 1–3 were corrected. These results do not demonstrate longer life in people or establish clinical cancer safety.
Epithalamin and Epitalon need separate evidence
Epithalamin is a pineal-derived peptide mixture; Epitalon is a defined four-amino-acid molecule. Long-term extract studies cannot be treated as trials proving that synthetic Epitalon extends human lifespan.

- Consciousness and immune markers
- Faster recovery and altered immune measures describedOriginal allocation and longer-term functional outcomes remain unresolved.
In the severe-injury table, day-five neuron-specific enolase was 23.2 ng/mL with both agents and 58.9 ng/mL with standard care. No formal interaction analysis was reported.
Study notes · methods, sources and limitations
Participants or model Hospitalized cold-injury patients. Three adjunct arms had 25 patients each. The severity-specific outcome tables use smaller subgroups.
Design Standard care alone or with Epitalon, Cortexin or both. Serial neuron-specific enolase, immune measures and clinical observations.
- Reported study exposure
- The author abstract reports intramuscular Epitalon 10 µg and Cortexin 10 mg daily for ten days, separately or together depending on arm.
Important limitations
- A historical treatment comparison with substantial concurrent care, small subgroup sizes and an imperfect source transcription.
- This is a patient rehabilitation study. The biomarker changes do not establish cold tolerance in healthy people.

Age and baseline anxiety in Lysenko’s peptide stress models
Study of multiple preparations
- High-anxiety young rats
- Vilon and GVS-111 were highlighted in the author’s conclusionsOriginal group-level numerical estimates and doses still need retrieval.
- Stress-response direction
- Favorable and unfavorable responses describedThe author discusses this for GVS-111 and an experimental preparation called NKT. NKT identity remains unresolved.
The author reported that the direction of peptide-associated changes depended on age and baseline anxiety. Some shifts were unfavorable.
Study notes · methods, sources and limitations
Participants or model Rats grouped by age and baseline anxiety; series-specific denominators remain unverified.
Design Hypokinesia, hypoxia and exertion models, with behavioral, immune and oxidative endpoints. Twenty-four-hour hypokinesia was one stress protocol.
Important limitations
- Potential overlap with narrower author-network dissertations, including Morgul and Rudenko. Outcomes cannot be pooled or assigned to humans.
- A mechanistic program on stress response. The dissertation-level conclusion does not isolate all preparation-specific effects.

Epitalon in the separate adult-hypoxia arm
Study of multiple preparations
- Respiration arrest
- 150 ± 38 secondsSaline 72 ± 10 seconds; n=10/groupp<0.08; not a demonstrated p<0.05 difference
- Adult mortality
- 20%Saline 10%; very small groups, no verified mortality difference test
In adult male rats, Epitalon was associated with 150 ± 38 seconds to respiration arrest versus 72±10 with saline. This arm did not expose pregnant animals to Epitalon.
Study notes · methods, sources and limitations
Participants or model Pregnant rats exposed to hypoxia on gestation day 10; separate adult-male experiment, n=10/group; offspring open-field strata n=6, 11, 9 and 12
Design Two distinct experiments: five-day pretreatment in adult males, and maternal Pinealon after gestation-day-10 hypoxia. Offspring cerebellar cells tested at day 12; open-field behavior at four weeks, stratified by maternal hypoxia sensitivity.
Important limitations
- Only Pinealon was studied in the maternal arm of this publication. Adult hypoxia findings are adjacent context, not pregnancy-safety evidence.
- Animal injury experiments do not establish human pregnancy safety. Epitalon, Vilon and Vesugen were tested only in the adult-male arm of this paper. Number of pregnant dams, randomization, masking and litter-adjusted statistics are not established. Offspring are not independent maternal exposures. Table 1 mortality conflicts with the prose; do not convert the latter into a verified excess risk. Vilon and Epitalon respiration findings marked p<0.08 are not demonstrated p<0.05 results. The paper prints an Epitalon sequence ending in Arg; established Epitalon identity is Ala-Glu-Asp-Gly. That apparent source error is retained as an identity warning.

Melatonin and pineal gland peptides are able to correct the impairment of reproductive cycles in rats
Study of multiple preparations
- Epithalamin
- Recovery of norepinephrine diurnal dynamics in medial preoptic areaNorepinephrine decreased between 09:30 and 11:00 circadian time
- Epitalon
- Dopamine remained low at 05:00 and increased by 11:00 circadian timeMedian eminence/arcuate region; no numerical concentrations supplied
- Pregnancy and fertility outcomes
- No pregnant cohort, congenital-anomaly rate or verified live-birth benefit in the abstract
Epithalamin reportedly restored hypothalamic norepinephrine rhythms, while Epitalon had a stronger dopamine-rhythm effect in another hypothalamic region. The experiment used 1,2-dimethylhydrazine, not a pregnancy model or a methionine-only intervention.

Participants or model Nonpregnant female rats in a xenobiotic-induced reproductive-aging model; n absent from abstract
Design Single 1,2-dimethylhydrazine exposure in female rats; region- and circadian-time-specific catecholamine measurements after melatonin or pineal-peptide interventions.
Important limitations
- Reproductive-cycle neurochemistry is not pregnancy-safety evidence or proof of improved human fertility.
- Reproductive-cycle neurochemistry is not pregnancy-safety evidence or proof of improved human fertility. Epitalon is a defined tetrapeptide; Epithalamin is a bovine pineal peptide extract. Their findings are not interchangeable. Doses, n, allocation, quantitative effect sizes and adverse-event surveillance unavailable in the abstract.

Questions about Epitalon (Epithalon)
What is Epitalon, and is Epithalon the same peptide?
Epitalon and Epithalon are spellings used for the synthetic tetrapeptide Ala–Glu–Asp–Gly (AEDG). Epithalamin is a pineal-derived mixture, while Pinealon is the different tripeptide EDR. Similar names do not establish equivalent effects.
Does Epitalon lengthen telomeres?
Telomere lengthening has been reported in cell experiments. The 2025 paper describes different telomere-maintenance responses in normal and cancer cell lines and has an accompanying correction to Figures 1–3. A cultured-cell finding does not establish a useful treatment effect or longevity benefit in humans.
Are there human studies proving Epitalon extends lifespan?
The direct synthetic-Epitalon studies linked here do not establish human lifespan extension. There are human melatonin, circadian-marker and retinal reports, but these outcomes are different from survival. Long-term findings for the Epithalamin extract cannot be transferred to AEDG.

Does Epitalon improve sleep?
Small human studies report changes in melatonin or circadian-related markers. The 2007 low-melatonin subgroup had a higher nighttime melatonin concentration after treatment, while participants with preserved function showed no change. These measurements do not by themselves demonstrate better sleep, more REM sleep or an insomnia treatment effect.

What is known about Epitalon side effects and cancer safety?
The collection does not establish long-term clinical safety. Telomere findings in cancer cell lines are mechanistic observations; they prove neither that Epitalon causes cancer in people nor that it is safe in people with cancer. Laboratory and short clinical reports cannot settle that question.

- 2025: Correction: Epitalon increases telomere length in human cell lines through telomerase upregulation or ALT activity. ↗
- 2025: Overview of Epitalon—Highly Bioactive Pineal Tetrapeptide with Promising Properties ↗
What is known about Epitalon during pregnancy?
A small 2007 rat study gave Epitalon to five dams late in gestation. Exposed offspring had larger selected brain measurements, lower weight at day 40 and more anxiety-related behavior at day 30. These mixed developmental findings do not establish safety or benefit in human pregnancy. Epithalamin cycle-regulation research is a different preparation and model.
