Gonadorelin vs Dulaglutide
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.

Dulaglutide (Trulicity) is a once-weekly GLP-1 receptor agonist for type 2 diabetes. Its larger molecular size from fusion with an Fc fragment extends half-life and may reduce some GI side effects.

| Aspect | Gonadorelin | Dulaglutide |
|---|---|---|
| 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. | GLP-1 analog fused to a modified human IgG4 Fc fragment, providing extended duration of action. Activates GLP-1 receptors for glucose-dependent insulin secretion and appetite suppression. |
| Typical Dosage | Men: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies. | Start at 0.75mg once weekly, may increase to 1.5mg, 3mg, or maximum 4.5mg weekly based on glycemic response. |
| Administration | Subcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy. | Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens. |
| Side Effects | Headache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated. | Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration. |
