What Epitalon is
Epitalon (also spelled Epithalon) is a synthetic peptide of four amino acids: alanine, glutamic acid, aspartic acid, and glycine. It was developed in Russia based on a pineal gland extract.
It is marketed mainly for anti-aging, with claims that it lengthens telomeres, the protective caps on chromosomes.
Regulatory status in 2026
Epitalon is not approved and is not on the compounding list. It was part of the July 2026 FDA review.
Epitalon is removed from FDA's Category 2 list. Removal does not make it legal to compound.
FDA's advisory committee narrowly votes to recommend adding Epitalon to the compounding list for insomnia. FDA staff had objected, noting no published studies of its effect on insomnia in patients.
FDA has not added Epitalon to the compounding list.

Claims vs. what the research shows
Most Epitalon research comes from one research group, and much of it is in cells and animals.
Lengthens telomeres and slows aging.
Reported in cell and animal studies. Not shown in quality human trials.
Animal or limited evidenceImproves sleep.
FDA staff found no published efficacy studies in patients with insomnia.
Insufficient dataExtends lifespan.
Reported in some animal studies. No human evidence.
Animal or limited evidenceStorage and stability
Peptides break down with heat, light, moisture, and repeated freezing and thawing. Degraded product is one common reason two vials of the "same" peptide behave differently. These are general peptide handling practices. Your supplier's certificate of analysis or label takes priority.
Sealed powder (lyophilized)
- Refrigerate at 36 to 46°F (2 to 8°C) for routine storage.
- Freezer is generally used for long-term storage.
- Keep in its original sealed vial, away from light.
- Let a cold vial reach room temperature before opening to limit condensation.
After reconstitution
- Keep refrigerated. Do not freeze.
- Protect from light. Clear glass lets it through.
- Opened multi-dose bacteriostatic water is typically discarded 28 days after first puncture.
- Log the mix date so you know the vial's age at a glance.
Light exposure is easy to overlook in a fridge door that opens dozens of times a day. VIALTIGHT is building stackable cases that block light from every side. See vialtight.com for updates.
Reconstitution math
Concentration is just the amount of peptide divided by the volume of water added. On a U-100 insulin syringe, 100 units equals 1 mL, so each unit is 0.01 mL. Enter what is on your vial label and what you added to see the concentration.
This shows concentration only. It is not a dosing recommendation. VialTracker runs this math for every vial you log and keeps it with the vial's history.
Safety flags
Product quality is unverified. Gray-market vials have been found underdosed, mislabeled, or contaminated. A certificate of analysis from the seller is not the same as independent testing.
Immune reaction risk. FDA flagged possible immune reactions, potentially worsened by aggregation, and peptide-related impurities.
Human safety is unknown. There is no long-term human safety data.
FAQ
Is Epitalon legal?
It is not FDA-approved and not on the compounding list, so it cannot be legally marketed for human use.
Does Epitalon lengthen telomeres in people?
That has not been shown in quality human trials.
Does VialTracker tell me what to take?
No. VialTracker organizes the information you enter and runs the math. It does not recommend doses, products, or protocols.
