Your dose, on the dial.
The dial counts in units of 0.01 mL: 10 units is 0.10 mL, and 100 units, the most one press gives, is 1 mL. How much peptide a unit holds depends on the pen’s strength, so the same number of units gives a different dose on each pen. Enter the dose your doctor gave you to see how many units to set.

About MOTS-c
What MOTS-c is
MOTS-c is a short peptide coded in the DNA of your mitochondria, the parts of each cell that make energy, rather than in the DNA of the cell’s nucleus.
Every result so far comes from mice. No published study has given MOTS-c to people, and a first trial, in adults with prediabetes, is now recruiting.
What MOTS-c is studied for
- Weight: Studied in mice on a high-fat diet.
- Endurance: Studied in old mice, who were given injections for two weeks.
- Aging: Studied for lifespan in the same mice.
What the research shows.
MOTS-c is a short peptide coded in the DNA of your mitochondria, the parts of each cell that make energy. Every result so far comes from mice, and no published study has given MOTS-c to people. Each study used its own supply, dose and schedule, so its results describe that study rather than promise what this pen will do.
Weight
Animal studies, Mice
Mice on a high-fat diet given daily injections of MOTS-c stayed about 20% lighter than mice without it.
Endurance
Animal studies, Mice
After two weeks of injections, old mice ran about twice as far as untreated mice.
Aging
Animal studies, Mice
In the same study, treated mice did not live significantly longer than untreated mice.
How every lot is tested
Every lot of MOTS-c goes through three tests before it is sold.
-
Every lot is 99% pure or more, and your pen’s exact purity is printed on its tube.
-
Every lot we sell has passed the sterility test: no bacteria or other microbes were detected.
-
Every lot we sell has passed the test for endotoxins, traces of bacteria that can cause fever after an injection.
-
An independent laboratory in the USA runs every test.
Side effects and cautions
-
In human blood, MOTS-c is quickly cut into pieces.
-
A trial in adults with prediabetes is now recruiting.

The World Anti-Doping Agency bans MOTS-c in sport at all times, so an athlete who is tested for doping and uses this pen risks a violation.

Allergy warning
Don’t use MOTS-c if you have ever had an allergic reaction to it or to anything else in the pen. Get help straight away if you have swelling of the face, lips or throat, trouble breathing, or a rash that spreads after an injection.
Pregnancy and breastfeeding
MOTS-c has not been studied in pregnancy or breastfeeding. If you are pregnant, trying to become pregnant or breastfeeding, talk with your doctor before using it.
Medicines and health conditions
If you take any medicine or have a health condition, talk with your doctor before using MOTS-c, and tell them you use it.
Age
For adults 18 and over.
Frequent questions
Is MOTS-c right for me?
MOTS-c is for people interested in metabolism and healthy aging. Every result so far comes from mice, so no one can yet say what it does in people. Talk with your doctor before you start.
Has MOTS-c been tested in people?
Not yet. No published study has given MOTS-c to people. A trial in adults with prediabetes is now recruiting.
What side effects can MOTS-c cause?
No published study has given MOTS-c to people by injection under the skin, so how it acts that way in people, and its side effects, are not known. Tell your doctor about any reaction where you inject it, or anything else unusual.
What testing does Pure99 complete for MOTS-c?
Every lot of MOTS-c is tested by an independent laboratory in the USA before it is sold. The laboratory measures its purity by HPLC, tests it for bacteria and other microbes by PCR, and measures its endotoxins by LAL. Endotoxins are the toxins bacteria leave behind even in a sterile solution, and they can cause fever and aches after an injection.
How much MOTS-c should I take?
Take MOTS-c only as your doctor directs: Pure99 doesn’t recommend a dose. The pen’s dial counts in units of 0.01 mL, from 1 to 100 a press, and the same number of units gives a different dose on each pen. The dose guide on this page turns your dose into the number of units to set.
How many doses are in one MOTS-c pen?
Every pen holds 3 mL, which is 300 units on the dial. How many doses that makes depends on your dose: the dose guide on this page shows how many doses of your size a pen holds.
