What is the difference between MOTS-c and Retatrutide?

MOTS-c (Mitochondrial-derived peptide MOTS-c) is graded B and is Not FDA-approved — research peptide; multiple early-phase clinical trials. Retatrutide (Retatrutide (LY3437943)) is graded A and is Not FDA-approved — Phase 3 trials (TRIUMPH program) for obesity. They are commonly compared because they share the categories: metabolic.

Which has stronger clinical evidence — MOTS-c or Retatrutide?

On our internal evidence scale, MOTS-c is B and Retatrutide is A. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of MOTS-c vs Retatrutide?

MOTS-c: 5–10 mg, 2–3 times weekly (subcutaneous). Retatrutide: Trial range: 1–12 mg weekly (subcutaneous). Always work with a licensed clinician — peptide dosing should be individualized.

MOTS-c vs Retatrutide

Both MOTS-c and Retatrutide are used for metabolic. Here's how their evidence, dosing, and regulatory status actually compare.

MOTS-c

Evidence B

Mitochondrial-derived peptide MOTS-c

A 16-amino-acid mitochondrial-derived peptide that improves insulin sensitivity and exercise capacity in animal models. Among the most promising 'mitokines' for metabolic aging.

Retatrutide

Evidence A

Retatrutide (LY3437943)

Triple agonist at GLP-1, GIP, and glucagon receptors. Phase 2 produced 24.2% mean weight reduction at 48 weeks — the highest ever in a clinical obesity trial.
