Gonadorelin vs Cagrilintide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Gonadorelin
Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural hormone production.

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 | Gonadorelin | Cagrilintide |
|---|---|---|
| Mechanism | Binds to GnRH receptors in the pituitary gland, triggering pulsatile release of LH and FSH. This stimulates testicular or ovarian function and natural sex hormone production. | 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 | Men: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies. | Clinical trials: 2.4mg weekly as monotherapy or in combination with semaglutide 2.4mg (CagriSema). Optimal dosing still being determined. |
| Administration | Subcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy. | Subcutaneous injection once weekly. Currently only available in clinical trials - not yet FDA approved. |
| Side Effects | Headache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated. | Nausea, vomiting, diarrhea, constipation similar to other incretin-based therapies. Combination with semaglutide may increase GI effects initially. |
