Nicholas TrigiliHuman performance specialist and coach; fitness YouTuber

Own use: current routine

Dose
“5 to 10 mg per week”
How often
“dose the same exact way”
How long
“first two to four weeks by itself”

“And SS-31, 5 to 10 mg per week, dose the same exact way. If I'm cycling together though, I start SS-31 by itself for the first two to four weeks to repair the machine. Then, you can layer MOTS-c on top of that.”

Start before MOTS-c

Dose
“2 mg”
How often
“five times per week”
How long
“four weeks … two to four weeks”

“So, here's how I would actually sequence this. I would start with SS-31 on its own. I would start with 2 mg five times per week for four weeks before I would start MOTS-c. Now, you can technically go two to four weeks.”

Pulse dosing alongside retatrutide

Dose
“5 to 10 milligrams … starting at 5 millig”
How often
“two to three times per week … three times a week”
How taken
“subq”

“The way I like to run MOTS-c is running it like this. I take 5 to 10 milligrams subq subcutaneously two to three times per week. Most people do well starting at 5 millig three times a week and adjusting it from there”

Context: This is a higher weekly total than the “5 to 10 mg per week” he gives in his July 2026 videos (above). Caption spelling of the compound name corrected: “Matzi” → MOTS-c. He says in his videos that he is not a doctor.

Dr William SeedsOrthopaedic surgeon; founder of the International Peptide Society

For a healthy person: once a week

Dose
“10 milligrams”
How often
“once a week”
How taken
“subcutaneous injection”

“They want to control, and moderate that metabolism, so everything is functioning at its highest, and they want to improve their exercise capacity of the cell. Then that’s basically something where you would use 10 milligrams, and you’d use it once a week if we have, and that’s a subcutaneous injection, and what you need to know about MOTS-c. It is very fragile. It needs to be kept in a dark space in a refrigerator. And once you reconstitute it, you’ve got four hours to use it or less or it’s no good anymore.”

How taken
“sub Q”

“I, I, I do it intermittently […] you can do the protocols 10 milligrams once a week or 5 milligrams sub Q twice a week, um, you could go a little further if you have an event, like you're, you're, you're trying to like, yeah, run faster, like you have a marathon coming up or something like that, but in general just, uh, once to two times a week”

Own use and advice: start low

Dose
“micro administrations”
How often
“daily”
How taken
“subcutaneous”

“So for those people and for most people I would suggest just to start low, start with subcutaneous administrations and build your ways up. If you go with 10 milligrams intramuscularly, it's probably not going to end well for you. […] So, um, I circumvent that by doing daily micro administrations of modsi subcutaneously.”

How long
“8 to 12 weeks maximum, then a month or two off”
How taken
“injection”
When
“Morning”

“The protocol that our medical team uses is 10 mg in a single injection once a week. Morning administration. This is what I see working. If you want to load in faster, you can hit a saturation point. Some patients will run it up to three times per week just for two weeks. Same 10 mg dose, but three times a week. After that, back to once a week. 8 weeks to 12 is a maximum cycle before you take a break, say a month or two off.”

Trial dose vs grey-market dose

Dose
“somewhere between 2 and 10”

“none of this is me writing you a prescription. […] Every pivotal human trial dosed this at 40 mg a day. The gray market crowd, mostly because this stuff is expensive, is mostly running at somewhere between 2 and 10. So, when you see all those I tried SS-31 and felt nothing reports, that isn't necessarily the drug failing you. It might be a quarter of the dose that also did nothing in the formal trial.”

What the research used

MOTS-c

The MOTS-c studies we could verify are in mice and cells. No published clinical trial of injected MOTS-c in people was found, so none of this establishes a human dose.

See the studies on the MOTS-c page

SS-31 (elamipretide)

These are the conditions used in clinical trials of elamipretide in specific diseases. Several trials missed their main goals. They are not a guide for other uses.

See the studies on the SS-31 (elamipretide) page

MOTS-c is stocked at Peptides EU.
