\*\*Mitochondrial Open Reading Frame of the 12S rRNA-c\*\* · Longevity & Anti-Aging · Preliminary Evidence · Research Only A mitochondria-encoded peptide that regulates metabolic homeostasis and has demonstrated remarkable longevity effects. ### Description MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid peptide encoded within the mitochondrial genome — specifically within the 12S rRNA gene. Discovered in 2015, it is the first mitochondria-derived peptide (MDP) shown to translocate to the nucleus and directly regulate nuclear gene expression, establishing a new class of mitochondria-to-nucleus communication. MOTS-c is considered a “mitokine” — a hormone-like signal released from mitochondria in response to metabolic stress. Circulating MOTS-c levels decline with age and correlate with metabolic health, and MOTS-c polymorphisms in humans are associated with longevity in Japanese centenarian studies. It has demonstrated remarkable effects on insulin sensitivity, exercise performance, metabolic homeostasis, and lifespan in multiple model organisms. ### Key Characteristics - \*\*Molecular Formula:\*\* C95H163N29O27S2 - \*\*Molecular Weight:\*\* 2174.6 Da - \*\*Half-Life:\*\* ~30 minutes to 2 hours - \*\*Administration Routes:\*\* Subcutaneous injection - \*\*Typical Dose:\*\* 5–10 mg - \*\*Frequency:\*\* 3–5x per week ### Investigated Benefits - Improved insulin sensitivity - Enhanced exercise performance - Metabolic homeostasis regulation - Potential lifespan extension - Anti-inflammatory effects \\\* Benefits based on preclinical/animal research unless otherwise noted. ### Mechanism of Action MOTS-c’s primary mechanism involves activation of AMPK (AMP-activated protein kinase) — the master cellular energy sensor — through inhibition of the folate cycle and de novo purine synthesis. When MOTS-c inhibits AICAR transformylase, AICAR accumulates and activates AMPK. AMPK activation then drives metabolic adaptations: increased fatty acid oxidation, enhanced glucose uptake via GLUT4 translocation, improved mitochondrial biogenesis via PGC-1α, and inhibition of mTOR. Under metabolic stress, MOTS-c translocates to the nucleus where it binds to the ARE (antioxidant response element) and activates Nrf2 target genes, providing cytoprotection. MOTS-c also modulates the gut microbiome and has direct anti-inflammatory effects through NF-κB inhibition. ### Dosing Protocol - \*\*Typical Dose:\*\* 5–10 mg - \*\*Frequency:\*\* 3–5x per week - \*\*Cycle Length:\*\* 4–8 weeks - \*\*Administration:\*\* Subcutaneous injection \*\*Protocol Notes:\*\* Some practitioners use it pre-exercise for metabolic benefits. Start with lower doses. Limited human data — use with caution. ### Reconstitution Guide Add 2 mL bacteriostatic water to 10 mg vial → 5 mg/mL ### Storage Information Lyophilized: refrigerate. Reconstituted: refrigerate and use within 14 days. ### Quality & Sourcing Standards When sourcing MOTS-c for research purposes, the following quality benchmarks should be verified before use. - \*\*Purity:\*\* \>98% (verified by HPLC) - \*\*Certificate of Analysis (COA):\*\* Must be provided by supplier - \*\*Endotoxin Testing:\*\* \<0.1 EU/mg (prevents bacterial contamination) - \*\*GMP Compliance:\*\* Manufactured in cGMP-certified facility - \*\*Third-Party Testing:\*\* Independent lab verification preferred ### Research Highlights 1. Demonstrated lifespan extension in C. elegans 2. Improved insulin sensitivity in obese mice 3. Enhanced exercise performance in aging mice ### Evidence Level \*\*Preliminary Evidence\*\* — Early-stage research only. Significant uncertainty about efficacy and safety in humans. ### FDA Disclaimer The statements made within this website have not been evaluated by the US Food and Drug Administration.
