CagriSema vs GHRP-6

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.

GHRP-6

Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.

Side-by-Side Comparison

AspectCagriSemaGHRP-6
MechanismCagriSema 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.Acts as a ghrelin mimetic, binding to the GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects.
Typical DosagePhase 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: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects.
AdministrationSingle subcutaneous injection once weekly, combining both peptides. Pre-filled pen device. Not yet commercially available. FDA response expected 2026.Subcutaneous injection. Best administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting.
Side EffectsPhase 3 data: nausea, vomiting, diarrhea, constipation (similar profile to semaglutide alone, but some reports suggest modestly higher GI rates). Decreased appetite. Injection site reactions.Intense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes.
