GHRP-6 vs Cagrilintide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →Cagrilintide
Cagrilintide is a long-acting amylin analog in development, showing promising results when combined with semaglutide (CagriSema). Amylin is a hormone co-secreted with insulin that promotes satiety.

| Aspect | GHRP-6 | Cagrilintide |
|---|---|---|
| Mechanism | 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. | Activates amylin receptors (calcitonin receptor with RAMP proteins) to slow gastric emptying, suppress glucagon secretion, and reduce food intake through central satiety mechanisms distinct from GLP-1. |
| Typical Dosage | Typical dosing: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects. | Clinical trials: 2.4mg weekly as monotherapy or in combination with semaglutide 2.4mg (CagriSema). Optimal dosing still being determined. |
| Administration | 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. | Subcutaneous injection once weekly. Currently only available in clinical trials - not yet FDA approved. |
| Side Effects | Intense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes. | Nausea, vomiting, diarrhea, constipation similar to other incretin-based therapies. Combination with semaglutide may increase GI effects initially. |
