Selank vs Setmelanotide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Selank
Selank is a synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia for anxiety and cognitive enhancement.
Full details →Setmelanotide
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 | Selank | Setmelanotide |
|---|---|---|
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | 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 | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Adults: Start 2mg daily, titrate based on tolerability up to 3mg daily. Pediatrics (6+): Weight-based dosing starting at 1mg daily. |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | Subcutaneous injection once daily. Requires genetic testing to confirm eligible mutations before prescribing. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Injection site reactions, skin hyperpigmentation, spontaneous penile erections, depression, and suicidal ideation (boxed warning). GI effects less common than GLP-1s. |
