Epitalon
Epithalon — synthetic tetrapeptide (Ala-Glu-Asp-Gly)
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed at the St. Petersburg Institute of Bioregulation and Gerontology. The most-studied peptide for telomerase activation and pineal regulation, with multi-decade Russian gerontology research showing extended lifespan in animal models and improved aging biomarkers in humans. Cycled 2× yearly in standard longevity protocols.
Quick reference
How Epitalon works
Epitalon was developed as a synthetic analog of epithalamin — a peptide complex isolated from bovine pineal gland in the 1970s by Russian gerontologist Vladimir Khavinson. The 4-amino-acid tetrapeptide (Ala-Glu-Asp-Gly) preserves the bioactivity with simpler pharmacology.
Primary documented mechanisms: telomerase activation (extending telomere length in cell-culture and animal studies), pineal gland regulation (restoring age-related decline in melatonin synthesis), and antioxidant gene expression modulation. The Russian research literature includes multi-decade studies showing extended lifespan in mice and rats, plus improved aging biomarkers (sleep quality, immune function, glucose metabolism) in elderly human cohorts.
Western research is limited — most published trials are Russian-language and Russian-conducted. This limits both regulatory approval (Epitalon is not FDA-approved or EMA-approved) and Western clinical adoption. Practitioner use in the West is research-chemical based with the standard caveats.
In the DoseCraft framework, Epitalon targets all three Root Causes indirectly via systemic anti-aging effects: Inflammation (improved circadian rhythm reduces inflammatory load), Insulin Resistance (improved sleep + hormonal regulation), and ATP Shortage (improved mitochondrial function via melatonin pathway).
Reconstitution math
- Remove the flip-off cap from the 10-50 mg vial.
- Draw 1-2 mL of bacteriostatic water into a sterile syringe.
- Inject slowly down the vial wall.
- Swirl gently. Do not shake.
- Refrigerate. Stable approximately 30 days at 2–8°C.
Dose math
50 mg vial + 5 mL bac water → 10 mg per mL.
On a 100-unit insulin syringe (1 IU = 0.01 mL):
- • 50 IU = 5 mg (5,000 mcg)
- • 100 IU = 10 mg (10,000 mcg)
- • Canonical daily dose: 500 mcg–1 mg per day (5–10 mg cumulative per 10–20 day cycle, NOT 5–10 mg per day)
Safety + side-effect profile
One of the safest peptides in clinical and research literature. No serious adverse effects reported in 30+ years of Russian usage data.
Not documented at standard doses: hepatotoxicity, hormonal disruption, cardiovascular effects, immune disruption. Contraindications: active malignancy (telomerase activation is theoretically concerning in oncology contexts — mainstream caveat), pregnancy, lactation.
Interaction notes: stacks well with most peptides. The cycled, infrequent dosing pattern means stack interactions are minimal. Avoid concurrent use with telomerase-inhibiting medications (rare, but exist in some experimental cancer protocols).
- • Improved sleep quality (intended effect, often immediate)
- • Mild fatigue first 3-5 days of cycle (common)
- • Rare injection-site soreness
- • Vivid dreams during cycles (melatonin regulation)
Frequently asked
What is Epitalon?
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed at the St. Petersburg Institute of Bioregulation and Gerontology. The most-studied peptide for telomerase activation and pineal regulation, with multi-decade Russian gerontology research showing extended lifespan in animals and improved aging biomarkers in humans.
What is the typical Epitalon dose?
Canonical foundational protocol: 500 mcg–1 mg subcutaneous DAILY for 10–20 days (5–10 mg total per cycle), then off 3–6 months. Run 2–3 cycles per year. PM only (bedtime — Epitalon disrupts circadian rhythm if dosed AM). Older community descriptions of "5–10 mg per day" reflect the per-cycle total being misread as a per-day dose — that would be a ~10× overdose. The canonical chapter (08-Epitalon, Khavinson protocol) is clear: 500 mcg–1 mg DAILY, 5–10 mg TOTAL per cycle.
Does Epitalon really activate telomerase?
Russian cell-culture and animal studies show measurable telomerase activation and telomere length extension. Western replication is limited. Real-world human telomere data is mostly observational. Practitioner expectation: Epitalon may modestly slow telomere attrition; it doesn't dramatically extend telomeres in healthy adults. Treat the longevity claim as plausible but not slam-dunk.
Is Epitalon FDA-approved?
No. Epitalon is not FDA-approved or EMA-approved. It's available in Russia and some Eastern European pharmacies. Western practitioner use is research-chemical based. Quality verification (HPLC + mass spec) is critical — lyophilized peptides without proper QC are common in the gray market.
How do I reconstitute Epitalon?
50 mg vial + 5 mL bacteriostatic water → 10 mg/mL. On a 100-unit insulin syringe, 50 IU = 5 mg, 100 IU = 10 mg. Refrigerate after reconstitution; stable approximately 30 days.
Will Epitalon help me sleep better?
Yes — this is the most consistently-reported benefit. Epitalon's effect on the pineal gland and melatonin synthesis improves sleep quality and circadian regulation. Most users notice improvement within 3-5 days of starting a cycle, which often persists for several months after the cycle ends.
Are there safety concerns with telomerase activation?
Theoretical concern: telomerase activation could promote cancer cell proliferation in users with undetected malignancies. Real-world evidence in 30+ years of Russian use does not show increased cancer rates, but the theoretical caveat applies. Avoid in active cancer therapy or recent cancer history.
Should I cycle Epitalon or use it continuously?
Cycle. Continuous Epitalon dosing is not better-supported in the literature than cycled use, and pulsatile dosing is closer to natural pineal pulse patterns. Standard protocol: 10-20 day cycles, 2× per year (every 6 months). Some longevity practitioners run shorter 5-day mini-cycles more frequently — also supportable.
