Ipamorelin vs MOTS-c

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

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	Ipamorelin	MOTS-c
Dose Range	100 mcg–300 mcg	5 mg–10 mg
Frequency	2x daily	Less than daily
Cycle Length	8–12 weeks	8–12 weeks
Route	subcutaneous	subcutaneous
Mechanism	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.	Activates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis.
Typical Dosage	Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295.	Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established.
Administration	Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides.	Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation.
Side Effects	Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially.	Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance.
