Ipamorelin vs Epithalamin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.
Full details →Side-by-Side Comparison
| Aspect | Ipamorelin | Epithalamin |
|---|---|---|
| Mechanism | 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. | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. |
| Typical Dosage | Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. |
| Administration | Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides. | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. |
| Side Effects | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. |
