Overview
Octreotide is primarily a hormonal peptide, while Semaglutide is used for weight management & metabolic.
This page compares Octreotide and Semaglutide across their primary use, typical dosing, reported benefits and side effects, and U.S. regulatory status. For the full monograph on either compound — mechanism of action, clinical research, and references — follow the article links.
Side-by-side comparison
| Octreotide | Semaglutide | |
|---|---|---|
| Category | Hormonal | Weight Management & Metabolic |
| Regulatory status (US) | FDA approved | FDA approved |
| Typical dosage | 20–30 mg (LAR formulation, IM every 4 weeks); 100–600 mcg/day in divided doses (immediate-release SC) | 0.25-2.4 mg |
| Frequency | Every 4 weeks (LAR); two to four times daily (immediate-release) | weekly |
| Reported benefits | Reduction of growth hormone and IGF-1 in acromegaly, suppression of carcinoid flushing and diarrhea, control of VIPoma-associated watery diarrhea, antiproliferative effect on low-grade neuroendocrine tumors, reduction of urinary 5-HIAA biomarkers | Significant weight loss, improved blood sugar control, reduced cardiovascular risk, appetite suppression |
| Reported side effects | Gallstones and biliary sludge, diarrhea, nausea, abdominal discomfort, sinus bradycardia, hyperglycemia, hypoglycemia, hypothyroidism, steatorrhea, injection-site pain | Nausea, vomiting, diarrhea, constipation, potential pancreatitis risk |
Key differences
Primary use. Octreotide is categorised under Hormonal, while Semaglutide falls under Weight Management & Metabolic. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.
Regulatory status. Octreotide: FDA-approved. Semaglutide: FDA-approved.
Dosing. Octreotide is typically dosed at 20–30 mg (LAR formulation, IM every 4 weeks); 100–600 mcg/day in divided doses (immediate-release SC) (Every 4 weeks (LAR); two to four times daily (immediate-release)). Semaglutide is typically dosed at 0.25-2.4 mg (weekly).
Can you stack them?
Some protocols combine peptides, but stacking Octreotide and Semaglutide has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
