MOTS-c peptide dosage: what animal tests used
Every amount on this page came from an animal test. No safe dose or schedule has been found for people.
How should you read these animal dose numbers?
The first dose teams asked if MOTS-c changed fuel use or exercise in animals. They used shots and changed both the amount and timing for each test. Every amount on this page belongs to mice or other rodents, so none gives you a human plan. A safe human dose and its half-life are still unknown. Half-life means the time until half a dose remains in your blood. Keep that limit beside each number as you read. This page explains studies; it can’t plan a dose for you.
What MOTS-c dosage did mouse studies use?
All published dose studies used rodents. In 2015, the daily amount was 0.5 milligrams for each kilogram a mouse weighed, and shots continued for 8 weeks. For each kilogram, another group got 5 milligrams daily over 7 days [1]. The 2021 exercise team set the daily amount at 15 milligrams for each kilogram. A second group received 15 milligrams three times each week under the same weight rule [2]. A bone study used 5 milligrams daily for each kilogram over 12 weeks [4].
The smallest and largest amounts were far apart. The long fuel study used 0.5 milligrams for each kilogram; the exercise study used 15 milligrams [1][2]. Each team chose timing to fit its test. Some used daily shots for weeks, while the exercise team also tried three shots a week [1][2][4]. A heavier mouse received more, and a lighter mouse received less.
You need that weight rule to read the numbers. A weight-based mouse amount can’t become a human dose. No study has tested how your body responds as the amount changes [12]. You won’t find a human schedule here.
Where did scientists put the shots in animal tests?
In most mouse studies, the needle entered the space around the organs in the belly [1][2]. The shot didn’t go into the stomach, while other studies placed it beneath the skin. Cell studies put MOTS-c right onto cells in a dish [3][4]. Some teams changed the protein to help it cross a cell wall [4]. That changed form wasn’t the same as the MOTS-c used in every other test.
How often did mice receive MOTS-c?
Some mouse teams gave daily shots, while others gave them three times a week [1][2]. Those mouse plans don’t show how often you could take MOTS-c.
Where did the needle go in mice?
Scientists placed the needle inside the mouse’s abdomen [1][2]. That was a lab method, not a human shot site. No study in people tells you where a MOTS-c shot would go.
Can you take MOTS-c every day?
In 2015, some mice got 0.5 milligrams each day for every kilogram they weighed [1]. That mouse fact can’t set your daily timing [12].
How many weeks did the animal tests run?
One animal test lasted about a week, while another lasted twelve weeks [1][4]. Each team chose a length that fit its test. Researchers don’t know how long you could use MOTS-c safely [12].
Do scientists know how long MOTS-c stays in people?
Scientists haven’t measured the half-life of MOTS-c in people [12]. Half-life is the time until half a dose has left your blood. The unchanged protein may leave blood fast, but repeat shots in animals don’t reveal the human half-life [12]. Some teams changed MOTS-c so it could cross a cell wall more easily [4]. Results from that form may not fit the unchanged protein.
Human studies measured only the MOTS-c made by each person. Blood amounts differed with exercise and health. In 2024, one study found that certain amounts came with a higher chance of dying or having heart trouble while on dialysis [4][8][13]. Nobody in those studies received MOTS-c. Those checks of body-made MOTS-c can’t show what a shot would do in you.
Without a human half-life, no mouse amount can set your dose or the time between shots [12].
You can read the animal numbers, but you can’t use them as a schedule.
What don’t scientists know about harm and lab products?
People haven’t received added MOTS-c in a trial that checked side effects [12]. Animal studies didn’t find clear poisoning at the amounts used, but that doesn’t prove safety for you. You can’t assume that products sold only for lab tests contain the same thing each time. They don’t get the same checks for strength, purity, and germs as approved medicine [12].
You still lack three answers: human side effects, time in the blood, and the contents of each lab product. Sports bans are a different issue. MOTS-c legal status and pharmacy access explains the current rules.
What form does MOTS-c take for lab work?
MOTS-c may come as a powder with the water removed [4]. Mixing and storage depend on the seller and the study. There’s no approved form for treating people.
