Cagrilintide vs Semaglutide.
Quick Verdict
Cagrilintide is a metabolic primarily researched for weight loss, appetite reduction, glycemic control, while Semaglutide is a glp-1 agonist studied for fat loss, appetite control, cardiovascular benefits. A key distinction: Semaglutide has FDA approval status.
Side-by-Side Analysis
| Dimension | Cagrilintide | Semaglutide |
|---|---|---|
| Category | Metabolic | GLP-1 Agonist |
| Mechanism | Long-acting amylin analog that activates amylin receptors in the area postrema and hypothalamus to reduce appetite, slow gastric emptying, and suppress post-meal glucagon secretion. | GLP-1 receptor agonism mimics the incretin hormone to reduce appetite, slow gastric emptying, improve insulin sensitivity, and provide cardiovascular protection. |
| Half-Life | ~7 days | ~7 days |
| Route | SubQ | SubQ |
| Typical Dose | 500–4500 mcg | 250–250 mcg |
| Frequency | Weekly | 1x/wk |
| Evidence Level | Strong | Very Strong |
| Indexed Studies | 20+ indexed | 20+ indexed |

| Lowest Price | $69.99 / 10mg via Amino Club | $47.99 / 5mg via Amino Club |
| Per-mg Cost | $7.00/mg | $9.60/mg |
Mechanism of Action Comparison
How Cagrilintide Works
Cagrilintide Cagrilintide is a long-acting amylin analog investigated for weight loss, studied in Phase 2 trials for achieving over 10% body weight reduction when combined with semaglutide.
Long-acting amylin analog that activates amylin receptors in the area postrema and hypothalamus to reduce appetite, slow gastric emptying, and suppress post-meal glucagon secretion. Works on a distinct pathway from GLP-1 agonists, making it ideal for combination therapy.
How Semaglutide Works
Semaglutide Semaglutide is an FDA-approved GLP-1 receptor agonist used to treat type 2 diabetes (Ozempic) and obesity (Wegovy), reducing appetite and improving blood sugar control.
GLP-1 receptor agonism mimics the incretin hormone to reduce appetite, slow gastric emptying, improve insulin sensitivity, and provide cardiovascular protection.
Key Mechanistic Difference
Cagrilintide operates as a metabolic, while Semaglutide functions as a glp-1 agonist — these are fundamentally different pharmacological approaches.
