MOTS-c
Mitochondrial-derived peptide encoded in the 12S rRNA. Preclinical data on insulin sensitivity, exercise capacity, and metabolic health. No FDA approval. Human data limited to small studies.
Educational only — not medical advice. SmartPeptide does not prescribe, diagnose, or treat. Always consult a licensed healthcare provider before using any peptide, supplement, medication, or protocol.
What the research shows
Rodent and in-vitro work suggests MOTS-c improves insulin sensitivity and modulates metabolic pathways via AMPK. Lee et al. (Cell Metab 2015) is the foundational paper.
What's still experimental
Virtually all human use is experimental. Dose-finding, route of administration, and durability of effect are unestablished.
Anecdotal / community reports
Heavy community interest for 'longevity stacks'. Self-reported energy/recovery improvements are common but uncontrolled.
Anecdotal reports are NOT scientific evidence. They reflect personal experience and may not generalize.
FDA approval status
Source: openFDA + DailyMed (NIH/NLM)Doses studied in research
Source: Published clinical trialWhat published trials tested or FDA-approved labels specify. Reporting research facts — not a SmartPeptide recommendation.
The doses below are aggregated from research-peptide community forums (Reddit, biohacker discussions). They are NOT supported by clinical trials, NOT FDA-approved, and NOT a SmartPeptide recommendation. Source purity, dose accuracy, and user-reported outcomes are unverifiable. We display this only because the information is publicly available elsewhere — visitors should absolutely consult a licensed clinician familiar with experimental peptides before any use.
Notes from the source: Only preclinical (rodent) data exists. The FDA has issued enforcement actions against companies marketing MOTS-c as injectable for human use.
How clinicians typically protocol this
Third-party reference · not our recommendationDosing phases, cycle lengths, and administration timing as listed in a compounding-pharmacy clinician reference guide. Shown so you can see what a real protocol looks like — and bring informed questions to a licensed clinician.
Dose numbers, frequencies, and cycle lengths in this panel are extracted from a clinician-facing reference protocol distributed by a US-based compounding pharmacy in November 2025. SmartPeptide has paraphrased all descriptive text and adds no endorsement. Always consult a licensed clinician.
16-amino-acid mitochondrial-encoded peptide; studied for metabolic and mitochondrial signaling.
Protocol phases
4 weeks on, then a break.
Protocol notes: Reference flags reduced stability post-reconstitution (some literature suggests as little as ~10 minutes at room temp — data still emerging).

- Mitochondrial-derived peptide MOTS-cA0A0C5B5G6gene: MT-RNR1Homo sapiens· 16 aaReviewed
Regulates insulin sensitivity and metabolic homeostasis (PubMed:25738459, PubMed:33468709). Inhibits the folate cycle, thereby reducing de novo purine biosynthesis which leads to the accumulation of the de novo purine synthesis intermediate 5-aminoimidazole-4-carboxamide (AICAR) and the activation of the metabolic regulator 5'-AMP-activated protein kinase (AMPK) (PubMed:25738459). Protects against age-dependent and diet-induced insulin resistance as well as diet-induced obesity (PubMed:25738459)…
- Cyclic AMP-dependent transcription factor ATF-1P18846gene: ATF1Homo sapiens· 271 aaReviewed
This protein binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Binds to the Tax-responsive element (TRE) of HTLV-I. Mediates PKA-induced stimulation of CRE-reporter genes. Represses the expression of FTH1 and other antioxidant detoxification genes. Triggers cell proliferation and transformation
- Nuclear factor erythroid 2-related factor 2Q16236gene: NFE2L2Homo sapiens· 605 aaReviewed
Transcription factor that plays a key role in the response to oxidative stress: binds to antioxidant response (ARE) elements present in the promoter region of many cytoprotective genes, such as phase 2 detoxifying enzymes, and promotes their expression, thereby neutralizing reactive electrophiles (PubMed:11035812, PubMed:19489739, PubMed:29018201, PubMed:31398338). In normal conditions, ubiquitinated and degraded in the cytoplasm by the BCR(KEAP1) complex (PubMed:11035812, PubMed:15601839, PubMe…

Funder diversity is a credibility signal. Research concentrated in a single drug company's funding warrants more scrutiny than research funded across NIH, charities, and academic grants.
