Semaglutide vs HGH Fragment 176-191
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.

HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

| Aspect | Semaglutide | HGH Fragment 176-191 |
|---|---|---|
| Mechanism | 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. | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. |
| Typical Dosage | 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. | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. |
| Administration | 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. | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. |
| Side Effects | Common: nausea, vomiting, diarrhea, constipation, abdominal pain. These typically decrease over time. May cause injection site reactions. | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. |
