Humanin vs Semaglutide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Humanin
Humanin is a mitochondrial-derived peptide with potent cytoprotective effects. Discovered in 2001, it has shown promise in protecting against age-related diseases including Alzheimer's, cardiovascular disease, and diabetes.
Full details →Semaglutide
Semaglutide is a GLP-1 receptor agonist that has revolutionized weight management and diabetes treatment. FDA-approved as Ozempic (diabetes), Wegovy (weight loss), and Rybelsus (oral form), it has become one of the most prescribed peptides worldwide.
Full details →Side-by-Side Comparison
| Aspect | Humanin | Semaglutide |
|---|---|---|
| Mechanism | Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress. | Mimics glucagon-like peptide-1 (GLP-1) to stimulate insulin secretion, suppress glucagon release, slow gastric emptying, and reduce appetite through hypothalamic signaling. The result is significant reduction in food intake and improved glycemic control. |
| Typical Dosage | Research protocols vary widely. Studies have used doses from micrograms to milligrams depending on the analog and route. HNG (S14G-Humanin) is a more potent analog. | Wegovy (weight loss): Start at 0.25mg weekly, titrate up to 2.4mg weekly over 16-20 weeks. Ozempic (diabetes): 0.25mg to 1mg weekly. Research protocols vary. |
| Administration | Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities. | Subcutaneous injection once weekly, typically in abdomen, thigh, or upper arm. Rybelsus is taken orally on empty stomach. Dose titration is essential to minimize GI side effects. |
| Side Effects | Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism. | Common: nausea, vomiting, diarrhea, constipation, abdominal pain. These typically decrease over time. May cause injection site reactions. |
