Epithalamin vs Setmelanotide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.

Setmelanotide (Imcivree) is an FDA-approved MC4R agonist for chronic weight management in patients with obesity due to specific genetic conditions (POMC, PCSK1, or LEPR deficiency).
Full details →Side-by-Side Comparison
| Aspect | Epithalamin | Setmelanotide |
|---|---|---|
| Mechanism | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. | Selective agonist of melanocortin 4 receptors (MC4R) in the hypothalamus, restoring the satiety signaling pathway that is disrupted in certain genetic obesity syndromes. |
| Typical Dosage | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. | Adults: Start 2mg daily, titrate based on tolerability up to 3mg daily. Pediatrics (6+): Weight-based dosing starting at 1mg daily. |
| Administration | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. | Subcutaneous injection once daily. Requires genetic testing to confirm eligible mutations before prescribing. |
| Side Effects | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. | Injection site reactions, skin hyperpigmentation, spontaneous penile erections, depression, and suicidal ideation (boxed warning). GI effects less common than GLP-1s. |
