Shared Similarities
- Both are included in the Relay research library, but their current records answer substantially different questions.
⇄ Different
Biggest Difference
MOTS-c is distinguished by mOTS-c is a 16-amino-acid peptide encoded within mitochondrial DNA. Human studies mostly measure the body's own MOTS-c; administered treatment evidence remains preclinical while a Phase 2a trial is enrolling; Semaglutide is distinguished by single GLP-1 receptor agonist with multiple approved injection and tablet products and mature outcomes evidence.
? Unknown
Biggest Unknown
No direct head-to-head study establishes how these compounds compare under the same population, dose, duration, and endpoints.
Key Takeaways
MOTS-c is distinguished in the current record by mOTS-c is a 16-amino-acid peptide encoded within mitochondrial DNA. Human studies mostly measure the body's own MOTS-c; administered treatment evidence remains preclinical while a Phase 2a trial is enrolling. Semaglutide is distinguished by single GLP-1 receptor agonist with multiple approved injection and tablet products and mature outcomes evidence. Neither is objectively “better”; the useful question is which evidence record addresses the research question being asked.

Question by question
What each evidence base can actually answer
Regulatory statusEvidence, not a winner
MOTS-cInvestigational
Investigational
SemaglutideFDA-labeled indications
FDA approved in product-specific formulations for defined weight-management, type 2 diabetes, cardiovascular, kidney, and MASH indications.
Evidence depthEvidence, not a winner
MOTS-cProfile in progress
Endogenous MOTS-c changes with exercise and is associated with some human metabolic phenotypes, but no completed controlled efficacy results for administered native MOTS-c were available.
SemaglutideMature Phase 3 + outcomes
Multiple large Phase 3 programs and outcomes trials, including SELECT, FLOW, ESSENCE, STEP TEENS, and the higher-dose STEP UP program.
Weight outcomesEvidence, not a winner
MOTS-cRecord incomplete
No dedicated weight-outcome summary has been editorially approved.
SemaglutidePeer-reviewed Phase 3
STEP 1 reported −14.9% mean change at 68 weeks with 2.4 mg versus −2.4% placebo. STEP UP later reported −18.7% with 7.2 mg, −15.6% with 2.4 mg, and −3.9% with placebo at 72 weeks.
Type 2 diabetesEvidence, not a winner
MOTS-cRecord incomplete
No dedicated diabetes-outcome summary has been editorially approved.
SemaglutideApproved + extensive trials
Approved injection and oral products have extensive type 2 diabetes evidence. Product names, routes, strengths, and label instructions are not automatically interchangeable.
Obstructive sleep apnoeaEvidence, not a winner
MOTS-cRecord incomplete
No dedicated obstructive-sleep-apnoea outcome summary has been editorially approved.
SemaglutideNo approved indication
No FDA-approved semaglutide indication for obstructive sleep apnoea was identified in the current U.S. labels.
Cardiovascular outcomesEvidence, not a winner
MOTS-cRecord incomplete
No dedicated cardiovascular-outcome summary has been editorially approved.
SemaglutideSELECT + labeled uses
SELECT demonstrated fewer major cardiovascular events in adults with established cardiovascular disease and overweight or obesity without diabetes. Other approved product labels cover defined diabetes populations.
Administration and handlingEvidence, not a winner

Current FDA labels include weekly subcutaneous injections and daily oral tablets with product-specific administration, switching, and storage instructions. Approved products require no reconstitution.
Comparison limitationsUnderstand what this comparison cannot establish before interpreting separate studies.
Very limited comparison
- No direct head-to-head trial is represented for this pair.
- Separate studies may use different populations, endpoints, durations, doses, routes, and estimands.
- Results should not be interpreted as comparative superiority or individual guidance.
Current unknowns
Questions the evidence cannot answer yet
- Whether administered native MOTS-c improves meaningful human outcomes and whether repeated exposure is safe.
- Long-term comparative outcomes across newer products and doses, rare events at population scale, and evidence outside studied populations or approved products.
