Epitalon vs Ipamorelin

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.

Ipamorelin

Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.

Side-by-Side Comparison

Aspect	Epitalon	Ipamorelin
Dose Range	5 mg–10 mg	100 mcg–300 mcg
Frequency	1x daily	2x 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.	Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones.
Typical Dosage	Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year.	Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295.
Administration	Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously.	Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides.
Side Effects	Generally well-tolerated. May affect sleep patterns initially.	Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially.
