Retatrutide vs MOTS-c
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Retatrutide
Retatrutide is an investigational triple agonist targeting GIP, GLP-1, and glucagon receptors. Phase 2 trials showed unprecedented weight loss of up to 24% at 48 weeks, making it potentially the most effective obesity treatment studied.

MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide that plays a key role in metabolic regulation and has emerged as a significant longevity research target.

| Aspect | Retatrutide | MOTS-c |
|---|---|---|
| Mechanism | Triple receptor activation provides complementary metabolic effects: GLP-1 and GIP reduce appetite and improve insulin sensitivity, while glucagon receptor activation increases energy expenditure and promotes hepatic fat oxidation. | 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 | Clinical trials used doses from 1mg to 12mg weekly. Optimal dosing still being determined in ongoing Phase 3 trials. | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. |
| Administration | Subcutaneous injection once weekly. Currently only available through clinical trials - not yet FDA approved. | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. |
| Side Effects | Similar GI effects to other incretin-based therapies: nausea, diarrhea, vomiting, constipation. Dose-dependent severity. | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. |
