Dulaglutide vs GHRP-2

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Dulaglutide

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.

GHRP-2

Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.

Side-by-Side Comparison

Aspect	Dulaglutide	GHRP-2
Dose Range	750 mcg–4.5 mg	100 mcg–300 mcg
Frequency	Less than daily	3x daily
Cycle Length	12–52 weeks	8–12 weeks
Route	subcutaneous	subcutaneous
Mechanism	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.	Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6.
Typical Dosage	Start at 0.75mg once weekly, may increase to 1.5mg, 3mg, or maximum 4.5mg weekly based on glycemic response.	Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release.
Administration	Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens.	Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep.
Side Effects	Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration.	Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations.
