CagriSema vs HGH Fragment 176-191
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
CagriSema
CagriSema is a fixed-ratio combination of cagrilintide (a long-acting amylin analog) and semaglutide, developed by Novo Nordisk. By combining two distinct appetite-regulating peptide hormones, CagriSema aims to achieve greater weight loss than semaglutide alone. Phase 3 data showed 22.7% body weight reduction, and an FDA response is expected in 2026.
Full details →HGH Fragment 176-191
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 | CagriSema | HGH Fragment 176-191 |
|---|---|---|
| Mechanism | CagriSema combines two complementary peptide mechanisms: (1) Semaglutide — GLP-1 receptor agonist providing glucose-dependent insulin secretion, glucagon suppression, delayed gastric emptying, and hypothalamic appetite suppression. (2) Cagrilintide — a long-acting analog of amylin, a peptide hormone co-secreted with insulin from pancreatic beta cells. Amylin activates amylin receptors (calcitonin receptor + RAMP complexes) in the area postrema and hypothalamus, providing additional appetite suppression via a distinct neuronal pathway from GLP-1. The combination produces additive weight loss by engaging two independent satiety signaling systems. | 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 | Phase 3 trial doses: cagrilintide 2.4 mg + semaglutide 2.4 mg weekly (fixed combination in a single injection). Dose escalation: start at cagrilintide 0.15 mg / semaglutide 0.25 mg weekly and escalate over 16 weeks to the maintenance dose. Administered as a single injection combining both peptides. | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. |
| Administration | Single subcutaneous injection once weekly, combining both peptides. Pre-filled pen device. Not yet commercially available. FDA response expected 2026. | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. |
| Side Effects | Phase 3 data: nausea, vomiting, diarrhea, constipation (similar profile to semaglutide alone, but some reports suggest modestly higher GI rates). Decreased appetite. Injection site reactions. | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. |
