Epithalon vs N-Acetyl Epitalon

Side-by-side comparison: effects, dosing ranges, side effects, regulatory status, and reconstitution.

Peptide A

Epithalon

Longevity

Synthetic pineal tetrapeptide that activates telomerase and modulates melatonin production.

Peptide B

N-Acetyl Epitalon

Longevity

Acetylated Epitalon variant — more stable, longer-acting form of the telomerase-activating tetrapeptide.

Typical vial

10 mg

Typical dose

5000-10000 mcg

Half-life

~30 minutes (short half-life but biological effects persist due to gene expression changes)

FDA status

Typical vial

5 mg

Typical dose

5,000-10,000 mcg

Half-life

Extended vs. parent Epitalon (acetylation effect)

FDA status

Not FDA approved.

Epithalon effects

  • Activates telomerase enzyme to elongate telomeres
  • Restores melatonin production in the pineal gland
  • Regulates neuroendocrine function and circadian rhythms
  • Reduces incidence of spontaneous tumors in animal models
  • Modulates gene expression patterns associated with aging

N-Acetyl Epitalon effects

  • Telomerase activation in dividing cells (extrapolated from Epitalon)
  • Telomere lengthening reported in long-term Russian studies
  • Modulation of pineal melatonin secretion
  • Reported reduction in age-related mortality in elderly study cohorts
  • Potential immune-modulating effects

Epithalon side effects

  • Mild injection site irritation
  • Occasional drowsiness (related to melatonin effects)
  • Rare mild headache
  • Transient changes in sleep patterns

N-Acetyl Epitalon side effects

  • Generally well-tolerated in Russian studies (parent Epitalon)
  • Mild injection-site reactions
  • Theoretical: telomerase activation in pre-cancerous cells
  • Limited Western safety data

Epithalon dosing ranges

Anti-aging and telomere support

5-10 mg · Once daily (SubQ) · 10-20 days, repeated 1-2 times per year

N-Acetyl Epitalon dosing ranges

Longevity research

5-10 mg · Once daily · 10-20 day cycles, repeated 2-3 times per year

Epithalon vs N-Acetyl Epitalon — common questions

What is the difference between Epithalon and N-Acetyl Epitalon?

Epithalon: Synthetic pineal tetrapeptide that activates telomerase and modulates melatonin production. Typical dose 5000-10000 mcg. N-Acetyl Epitalon: Acetylated Epitalon variant — more stable, longer-acting form of the telomerase-activating tetrapeptide. Typical dose 5,000-10,000 mcg. Both fall under the Longevity category.

Can you stack Epithalon and N-Acetyl Epitalon?

Stacking Epithalon with N-Acetyl Epitalon is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.

Which is dosed more frequently, Epithalon or N-Acetyl Epitalon?

Epithalon is typically dosed: Once daily (SubQ) for Anti-aging and telomere support. N-Acetyl Epitalon is typically dosed: Once daily for Longevity research.

Are Epithalon and N-Acetyl Epitalon FDA approved?

Epithalon: Not FDA approved for human use. No clinical trials submitted to the FDA. N-Acetyl Epitalon: Not FDA approved.
