Setmelanotide vs SHLP2
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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 →SHLP2
SHLP2 (Small Humanin-Like Peptide 2) is a mitochondrial-derived peptide similar to humanin. It has shown insulin-sensitizing and cytoprotective effects in research, with potential metabolic benefits.
Full details →Side-by-Side Comparison
| Aspect | Setmelanotide | SHLP2 |
|---|---|---|
| Mechanism | Selective agonist of melanocortin 4 receptors (MC4R) in the hypothalamus, restoring the satiety signaling pathway that is disrupted in certain genetic obesity syndromes. | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. |
| Typical Dosage | Adults: Start 2mg daily, titrate based on tolerability up to 3mg daily. Pediatrics (6+): Weight-based dosing starting at 1mg daily. | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. |
| Administration | Subcutaneous injection once daily. Requires genetic testing to confirm eligible mutations before prescribing. | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. |
| Side Effects | Injection site reactions, skin hyperpigmentation, spontaneous penile erections, depression, and suicidal ideation (boxed warning). GI effects less common than GLP-1s. | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. |
