PE-22-28 vs Epitalon
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
PE-22-28
PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline.
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 | PE-22-28 | Epitalon |
|---|---|---|
| Mechanism | Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| Administration | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Very limited human data. Primarily studied in animal models for safety and efficacy. | Generally well-tolerated. May affect sleep patterns initially. |
