MOTS-c — Why I Started, What It Does, and 6 Months Later
A wall that training alone couldn't fix — and what changed.
I want to be upfront before anything else — this isn't a sales pitch and it isn't medical advice. What I'm sharing is my own personal experience: six months of running MOTS-c, what drove me to it, and what honestly changed. If you're researching this compound yourself, I hope this gives you something real to work with rather than the surface-level content you usually find online.
Why I Started
About eight months ago, I hit a wall that training alone couldn't fix.
I've been in and around fitness for 28 years. I train hard. I eat well. I take my recovery seriously. But no matter what I did, my energy levels were consistently flat. Not slightly tired — genuinely struggling. I was waking up already depleted, dragging myself through the day, and by the time I had any hours left for my family, I had nothing to give.
The worst part wasn't the training. I could still find the energy to train — I've always been able to dig for that. The problem was that training was taking the last of what I had. My girls would want to play and I'd be sitting there with absolutely nothing left in the tank. That hit me harder than any fatigue ever could.
I wasn't sleeping badly. I wasn't eating badly. There was no obvious reason. But I couldn't focus, I couldn't sustain attention, and the brain fog was real. I started looking deeper — not at stimulants or quick fixes, but at what was actually happening at a cellular level.
That's when I found MOTS-c.
What Is MOTS-c?
MOTS-c is a peptide encoded within the mitochondrial genome — specifically within the 12S rRNA gene. What makes it unusual is that it's one of the very few peptides the body produces that originates from mitochondrial DNA rather than nuclear DNA.
In plain terms: your mitochondria are your cells' energy-producing units. MOTS-c is a signalling peptide that those mitochondria produce — and it plays a direct role in how your body regulates energy metabolism, insulin sensitivity, and cellular stress responses.
Research has identified MOTS-c as an exercise-responsive peptide — levels naturally rise during physical activity. It works through the AMPK pathway (a key regulator of energy balance), and studies have shown it can improve glucose metabolism, increase fat utilisation, and support mitochondrial function, particularly under conditions of metabolic stress.
Crucially — this isn't a stimulant. It doesn't force your adrenals. It works with your mitochondria, not against your nervous system.
My Protocol
I've been running MOTS-c for just over six months. Here's exactly how I do it:
The weekends off and the 4-on-2-off cycle are both intentional. I don't want my body to become reliant on exogenous MOTS-c or to downregulate its own natural production. The goal is to support and optimise — not to create dependency.
I also listen to my body on any given morning. There are days where I wake up already sharp — clear head, energy present, focused before I've done anything. On those days I don't administer. If my body is already operating at that level naturally, introducing an additional dose can tip things the wrong way and actually leave me feeling fatigued or flat. Learning to read those signals took a few weeks but it's become intuitive.
What I Actually Noticed
I'll be straight — I was cautious about drawing conclusions too early. I'm a coach. I know placebo is real and I don't want to oversell anything based on early enthusiasm.
But six months in, I'm confident in what I'm experiencing.
Weeks 1–2
A quality of alertness in the mornings I hadn't felt in a long time. Not a stimulant buzz, not a caffeine hit — something steadier. Within 20 minutes of waking I was actually present. Clear. Able to think.
Weeks 3–4
Sustained energy through the day was undeniable. Even on nights where sleep wasn't great, I was still functional the next day in a way I hadn't been before. The gap between a bad night and a good day had narrowed significantly.
6 Months In
Training didn't change dramatically — I was already training hard. What changed was what was left afterwards. I'd finish a session and still have something in reserve. Enough to be present with my daughters. Enough to think about the business. Enough to actually live the rest of my day rather than just survive it.
There are also particular mornings — maybe once or twice a week — where I wake up and something just feels different. Completely clear. Ready. Positive before anything has even happened. Those are the mornings I believe the compound has done its work and my mitochondria are running at a higher baseline. On those mornings I don't inject. I just run with it.
What I Don't Claim
I'm not saying MOTS-c cured anything. I'm not saying it will work the same way for you. My lifestyle, my training, my supplement stack, my sleep — all of those are factors. I can't isolate MOTS-c as the single variable.
What I can say is that in the context of everything I was already doing — which hadn't shifted the fatigue — adding MOTS-c was when things changed.
This is a research peptide. It is not a licensed medication. If you are considering it, that decision should involve your own research, your own health context, and a conversation with a medical professional. I am a personal trainer and wellness coach — not a doctor.
The Bigger Picture
I'll be writing about each compound I run — SS-31, SLU-PP-332, and others — with the same level of honesty. Not hype, not sales, just what I'm doing and what I'm experiencing.
If you're a client and want to discuss any of this in the context of your own protocol, you know where I am.
