Research & reference information

This profile compiles research and community-sourced reference information for educational purposes. Information may evolve as research and community knowledge develop. It is not individualized medical advice.

Overview

Epithalon (Epithalamin / AEDG) is a synthetic tetrapeptide modeled after a naturally occurring peptide produced by the human pineal gland.

What problem it targets: It targets cellular aging, telomere attrition, pineal gland calcification, disrupted melatonin cycles, and age-related functional decline.

What It Does

• Induces telomerase expression: Research shows it upregulates telomerase activity in human somatic cells, helping maintain and elongate telomere caps during cell division.

• Restores pineal gland secretory function: Reactivates the pineal gland, normalizing natural melatonin production, restoring youthful circadian sleep-wake cycles, and improving immune function.

• Modulates gene expression and chromatin: Promotes chromatin decondensation in aging cells, enabling cells to access repair genes and synthesize protective proteins.

• Realistic expectations: Epithalon is not an acute stimulant or immediate bodybuilder. It is run in short 10- to 20-day longevity cycles 1 to 2 times per year to support cellular longevity and biological age maintenance.

Reconstitution

Vial sizeBAC water / SolventConcentration
10 mg+ 0.50 mL20 mg/mL
50 mg+ 2.5 mL20 mg/mL Won’t dissolve? Epithalon is a small water-loving peptide and should clear readily in BAC water. If a vial clouds or clumps, let the powder reach room temperature and roll gently (never shake). Still cloudy, community practice is a few drops of 0.6% acetic acid first, then top up with BAC water. Needing acid is a lot-quality signal (request a COA), not the normal method; unlike IGF-1 LR3, where acetic acid is genuinely required.

Protocol

PhaseFrequencyDoseNotes
Days 1–10Daily or twice daily5–10 mg10 mg/day × 10 days standard.
Days 1–20Daily5 mgExtended course.
RepeatSeasonal2–3×/year4–6 months apart. Cycle: 10–20 day courses, 2–3× per year. Timing: 10-day course, daily SubQ pre-bed; repeat 2×/year. Evidence: telomerase effect shown in human cell lines + animals; clinical data is Russian/CIS, no Western RCT. By sex: Unisex bioregulator (pineal / telomerase), short courses, same dose in both sexes. Avoid in pregnancy.

Handling & Stacking

Injection site
SubQ abdomen or outer thigh.
Storage
  • Freeze-dried: -4°F.
  • Reconstituted: 36–46°F.
  • Best used within 28 days, otherwise potency gradually fades over ~4–6 weeks (structure-based estimate, no published data).
  • Protect from light.
Side effects
Generally very well tolerated. Rare: injection-site irritation.
What to expect
  • Improved sleep and circadian normalisation first (1–2 weeks).
  • Gradual energy and immune improvement over 2–3 annual courses.
  • Benefits compound over years.
  • Supply math 10mg → 10 vials | 50mg → 2 vials (10-day course @ 10 mg/day = 100 mg)
Pairs well with
Thymosin Alpha-1 (immune amplification); DSIP (sleep architecture, complementary circadian effect)
Avoid
Active malignancy. Pregnancy / nursing

Safety & Patient Education

Contraindications
Pregnancy and lactation (no safety data) Active malignancy (theoretical concerns; no human RCT data on cancer risk) Children and adolescents (no pediatric data outside Russian clinical use)
Warnings
Most clinical evidence is Russian/CIS, much doesn’t meet ICH-GCP standards No FDA approval; not regulated as drugs in the US Limited human safety data outside the Khavinson research group Long-term safety beyond 5 years of cyclic use not established Most-studied of the Khavinson peptides but still no Western RCTs PCAC RECOMMENDED it (as “epitalon”) for the 503A bulks list, 7–5 (Jul 2026; advisory, non-binding)
Labs
Compound-specific: Salivary melatonin at 9 PM (baseline + after 20-day course) No specific markers. Baseline CBC + CMP; target-tissue labs (salivary melatonin for Epithalon)
Patient education
Bioregulators, research use only in most jurisdictions Russian use approved; US/EU off-label or unapproved Quality varies, request COA for each lot 10-day courses, 2–3×/year; continuous dosing isn’t supported
