Epitalon vs MOTS-c
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.

MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide that plays a key role in metabolic regulation and has emerged as a significant longevity research target.

| Aspect | Epitalon | MOTS-c |
|---|---|---|
| Dose Range | 5 mg–10 mg | 5 mg–10 mg |
| Frequency | 1x daily | Less than daily |
| Cycle Length | 2–3 weeks | 8–12 weeks |
| Route | subcutaneous | subcutaneous |
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | Activates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. |
