MOTS-c 20mg vials are sold for laboratory research only. Learn how this mitochondrial peptide is studied, reconstituted, stored, and compared.
MOTS-c 20mg is a 20-milligram vial of the synthetic mitochondrial-derived peptide MOTS-c, supplied as a lyophilized powder for laboratory research only. It is not FDA-approved for human use, and no U.S. pharmacy dispenses it as a medicine. Labs favor the 20 mg format because it delivers more material per vial than the 5 mg or 10 mg sizes, which cuts down on reordering and reconstitution steps.
What MOTS-c Is and Where It Comes From
MOTS-c is a short peptide encoded inside the mitochondrial 12S ribosomal RNA gene. That makes it unusual, because most signaling peptides in the body are coded by nuclear DNA, while MOTS-c is produced in the mitochondria and can then travel to the nucleus to influence gene expression.
In cell and animal research, MOTS-c has been linked to:
- Activation of AMPK, a central energy-sensing pathway
- Improved insulin sensitivity and glucose handling in rodents
- Exercise-like metabolic changes in skeletal muscle
- Shifts in lipid metabolism and fatty acid oxidation
Almost all of that evidence comes from mice, rats and cultured cells. Human trials are sparse, so researchers treat MOTS-c as an investigational compound rather than a proven therapy.
Why Labs Buy the 20 mg Size
Research peptides are typically sold in 2 mg, 5 mg, 10 mg and 20 mg vials. A larger vial means fewer reconstitution steps, less vial-to-vial variability, and lower shipping and cold-storage overhead.
The trade-off is shelf life. Once a vial is reconstituted, the solution degrades over time, so a MOTS-c 20 mg vial makes sense for a multi-week rodent study but not for a small pilot assay that will only consume a few milligrams.
A 20 mg vial of one peptide is not equivalent to a 20 mg vial of another. The milligram number describes the mass of powder in the vial, not the potency or the amount that would be used in any experiment.
Reconstituting and Storing a MOTS-c 20 mg Vial
MOTS-c ships as a freeze-dried powder and must be reconstituted before use in cell culture or animal work. Bacteriostatic water is the standard diluent because the benzyl alcohol it contains slows bacterial growth inside a multi-use vial.
If you have ever worked out how much bac water to reconstitute 20mg tirzepatide, the arithmetic here is identical: total milligrams divided by milliliters of diluent equals concentration.
| Bacteriostatic water added | Concentration of a 20 mg vial | Typical use |
|---|---|---|
| 2 mL | 10 mg/mL | Small-volume, high-concentration work |
| 5 mL | 4 mg/mL | General lab use with standard syringes |
| 10 mL | 2 mg/mL | Measuring small aliquots accurately |
| 20 mL | 1 mg/mL | Cell culture and dilution series |
Add the water slowly down the inside wall of the vial, swirl gently, and never shake it, since agitation can shear the peptide chain. Keep the powder frozen and protected from light, and refrigerate the reconstituted solution at 2-8 °C (36-46 °F). Repeated freeze-thaw cycles are the most common cause of degraded peptide in a research setting.
What MOTS-c Benefits Are Studied For
Most interest in mots-c benefits centers on metabolic health and aging. Researchers examine whether the peptide can improve insulin sensitivity, increase fatty acid oxidation, or partially reproduce the metabolic signature of exercise.
Because MOTS-c levels appear to decline with age in some human observational data, it is also studied in the context of age-related metabolic decline. That work is early, and no study has shown that raising MOTS-c levels changes human health outcomes.
There is no published human trial demonstrating that MOTS-c cures or prevents any disease.
How MOTS-c Compares With Other Research Peptides
MOTS-c is often evaluated alongside other mitochondrial and metabolic peptides. The aod 9604 vs mots-c question comes up frequently because both are marketed around fat metabolism, but they are entirely different molecules with different mechanisms.
AOD-9604 is a fragment of human growth hormone (hGH 176-191) studied for lipolysis, while MOTS-c is a mitochondrial peptide studied for cellular energy sensing.
| Peptide | Primary research focus | Mechanism studied | Common research vial sizes |
|---|---|---|---|
| MOTS-c | Metabolic regulation, insulin sensitivity, aging | AMPK signaling and nuclear gene regulation | 10 mg, 20 mg |
| AOD-9604 | Fat metabolism | hGH fragment 176-191 acting on fat cells | 2 mg, 5 mg |
| SS-31 (elamipretide) | Mitochondrial protection | Cardiolipin binding on the inner mitochondrial membrane | 10 mg, 50 mg |
| Tesamorelin | Visceral fat and growth hormone axis | GHRH analog activity | 5 mg, 10 mg |
Stacking: MOTS-c With AOD-9604, SS-31 and Tesamorelin
Combination work is common in preclinical research because peptides acting on different pathways can be tested for additive effects.
Some protocols study aod 9604 and mots-c together on the theory that one targets fat mobilization while the other targets cellular energy sensing. Others propose a ss-31 and mots-c protocol that pairs mitochondrial membrane protection with metabolic signaling.
Human data on any of these combinations is essentially absent. Stacking also multiplies variables, which makes a mixed result nearly impossible to attribute to a single compound, and animal doses are reported per kilogram of body weight rather than as fixed amounts.
Legal Status, Quality and Safety
MOTS-c is not FDA-approved for human use in the United States. Vials sold online carry "for research use only" labeling and are not held to the manufacturing standards that apply to prescription drugs.
Purity and actual peptide content can therefore vary widely between vendors. A third-party certificate of analysis, mass spectrometry data and HPLC results are the minimum documentation a lab should request before purchasing.
In animal studies, MOTS-c has affected glucose and insulin handling, which is a meaningful consideration for anyone with a metabolic condition. Because no human safety data exist, anyone weighing experimental use should speak with a licensed healthcare professional first.
Frequently Asked Questions
What is MOTS-c 20mg?
MOTS-c 20mg is a 20-milligram vial of a synthetic mitochondrial-derived peptide, sold as a lyophilized powder for laboratory research. It is not an FDA-approved drug and is not intended for human consumption. Researchers use it in cell and animal studies of metabolism and aging.
How much bacteriostatic water should I add to a 20 mg MOTS-c vial?
There is no single required volume; the amount depends on the concentration your experiment needs. Adding 10 mL produces a 2 mg/mL solution, while 20 mL produces 1 mg/mL. Add the water gently down the vial wall, swirl instead of shaking, and refrigerate the reconstituted solution.
Is MOTS-c the same as AOD-9604?
No. AOD-9604 is a fragment of human growth hormone studied for fat metabolism, while MOTS-c is a mitochondrial-derived peptide studied for energy sensing and insulin sensitivity. They are different molecules with different mechanisms and are not interchangeable in research.
