- 0:00Framing and disclaimersDeLauer calls MOTS-c a standout for physical performance, says he has used it, and says he is not endorsing it and viewers should see a knowledgeable physician.
- 0:45Sponsor segmentHe promotes a discount on a daily probiotic and says gut health is the lowest hanging fruit. This part is not about peptides.
- 1:35Treadmill performance studyHe describes a Nature Communications paper in which treated animals showed no change at 7 days but a large gain by 10 days, with all of them reaching maximum effort versus 16.6% of controls.
- 2:36Human arm and exercise mimeticDeLauer says the same paper found MOTS-c rose 12-fold four hours after exercise in people, and that it is made by the mitochondria to drive adaptation.
- 3:38Diet and exercise interactionHe says preclinical work showed benefits even with a poor diet, and larger benefits when diet and exercise were already good.
- 4:09Myostatin as a ceilingDeLauer explains myostatin as a limit on muscle growth and compares MOTS-c's effect to follistatin gene therapy. He adds that more cellular energy output should also support training.
- 5:4040% myostatin reductionHe cites a preclinical study reporting a 40% reduction in myostatin, which he links to more mitochondria, better insulin sensitivity and weight loss.
- 6:10Atrophy and fat oxidationHe says preclinical work suggests MOTS-c protects against obesity-related muscle loss while increasing fat oxidation, through raised AMPK activity.
- 7:12Limits of the evidenceHe closes by noting the research is largely preclinical with limited human data, and that clinical trials are needed for safety and efficacy.
What the video says
Thomas DeLauer presents MOTS-c, a peptide produced by the mitochondria, as what he calls possibly the strongest peptide for physical performance in the literature he has read. He says he has used it himself and had good results, but he states repeatedly that he is not endorsing it and that viewers should talk to a physician experienced with peptides. The video is a solo explainer, and about a minute of it is a sponsor message for a probiotic product.
On performance, DeLauer describes a Nature Communications paper. In the preclinical part, treadmill performance did not change after 7 days of MOTS-c but changed sharply after 10 days. As the treadmill intensity rose, he says every treated animal reached maximum effort, against 16.6% of the untreated group. He adds that the human arm of the same paper found MOTS-c levels rose 12-fold four hours after exercise, which he takes as evidence the body makes it naturally and that it works as an exercise mimetic. He also says that with a poor diet it improved insulin resistance and limited weight gain in preclinical work, and that it worked better when diet and exercise were already good.
The muscle section centers on myostatin, which DeLauer compares to a ceiling on how much muscle a person can build. He says MOTS-c lowers myostatin in a way that resembles follistatin gene therapy, citing a study in the American Journal of Physiology Endocrinology and Metabolism that reported a 40% reduction. He also claims, based on preclinical work, that it protects against obesity-related muscle loss while supporting fat oxidation through AMPK activation.
DeLauer closes by acknowledging that the evidence is mostly preclinical, with limited human data, and says clinical trials are needed to establish safety and efficacy. Readers should treat the video as one creator's reading of selected studies, not as dosing or treatment guidance.
On each compound
MOTS-c0:00
DeLauer says MOTS-c is made by the mitochondria and acts like an exercise mimetic. He cites preclinical treadmill results, a 12-fold post-exercise rise in people, and a reported 40% myostatin reduction, while stressing the human evidence is limited and that he is not endorsing its use.
See how your DNA reads MOTS-cWhat this video doesn’t settle
- Most of the results DeLauer cites come from preclinical studies, and he acknowledges the human data is limited.
- The video gives no dose, route, duration or safety information for MOTS-c in people.
- His own good results are a single person's experience with no control group, and he does not describe them in detail.
Questions this video answers
What does Thomas DeLauer say MOTS-c does for exercise performance?
He cites a Nature Communications paper in which treated animals reached maximum treadmill effort every time, compared with 16.6% of untreated ones, after 10 days. He says the human arm of that paper found natural MOTS-c levels rose 12-fold four hours after exercise.
How does MOTS-c relate to myostatin and muscle growth?
DeLauer describes myostatin as a ceiling on muscle growth and says MOTS-c lowers it, citing a preclinical study that reported a 40% reduction. He compares the mechanism to follistatin gene therapy and says it appeared to protect against obesity-related muscle loss.
Is MOTS-c made naturally by the body?
DeLauer says it is produced by the mitochondria and partly encoded by mitochondrial DNA. He says its levels rise after exercise, which is why he calls it an exercise mimetic.
Does DeLauer recommend taking MOTS-c?
No. He says he has used it and had good results, but that he is not endorsing it. He tells viewers to talk to a physician who knows peptides and to do their own research.
