Dulaglutide vs Ipamorelin

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.

Ipamorelin

Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.

Side-by-Side Comparison

Aspect	Dulaglutide	Ipamorelin
Dose Range	750 mcg–4.5 mg	100 mcg–300 mcg
Frequency	Less than daily	2x 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.	Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones.
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 ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295.
Administration	Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens.	Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides.
Side Effects	Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration.	Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially.
