Noopept vs Epitalon
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Noopept
Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a peptide-derived nootropic developed in Russia. While technically a dipeptide prodrug rather than a true peptide, it's often discussed alongside peptide nootropics.
Full details →Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
Full details →Side-by-Side Comparison
| Aspect | Noopept | Epitalon |
|---|---|---|
| Mechanism | Metabolized to cycloprolylglycine which modulates AMPA and NMDA receptors, increases NGF and BDNF expression, and provides neuroprotective effects through antioxidant mechanisms. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Oral: 10-30mg daily, typically divided into 2-3 doses. Sublingual use may enhance absorption. Some users go higher but effects may plateau. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| Administration | Oral or sublingual administration. Unlike most peptides, it's orally bioavailable. Can be taken with or without food. | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Headache (often from choline depletion), irritability, insomnia if taken late, and occasional brain fog during initial use. | Generally well-tolerated. May affect sleep patterns initially. |
