Metabolic healthWhy the scale stops moving on a GLP-1 — and what to do about the plateauThe first three months were real. The number moved every week — sometimes every few days. Clothes fit differently. People asked if you'd done something different. You had more energy in the afternoon. And then, somewhere around month four or five, the scale stopped. You're eating the same way. You haven't quit the medication. The number just sits there, stubborn and unmoved, and the quiet voice that says maybe this is it, maybe this is as far as it goes, gets a little louder every week.4 min readImmune modulationME/CFS — myalgic encephalomyelitis and the peptide conversationYou went for a thirty-minute walk on Tuesday — not a run, not a hike, a walk — and on Wednesday you couldn't get out of bed. Not tired. Not sore. Something different and worse: a systemic shutdown that feels like the body pulling the plug, a heaviness in your limbs that isn't muscle fatigue, a brain that won't sequence thoughts, a flu-like wrongness with no fever that nobody around you can see. This is what post-exertional malaise feels like. It's the defining feature of myalgic encephalomyelitis, and it's the reason that almost every intuition you have about how to recover from fatigue is exactly wrong.9 min readMitochondrial healthNAD+ vs MOTS-c vs SS-31 vs Humanin — the mitochondrial peptide stack, decodedYou got your labs back and your biological age came out higher than your chronological age. Or the fatigue is real — not the kind that coffee fixes, not the kind that a good night's sleep fully resolves — a deeper, structural tiredness that has started to feel like a baseline rather than a symptom. Or you've been researching longevity seriously and you've arrived at the mitochondria, because the research keeps pointing there: cellular energy, oxidative stress, the gradual degradation of the organelles that power everything else. You've encountered four names being discussed — NAD+, MOTS-c, SS-31, Humanin — and you want to understand what each actually does, why they're being discussed together, and whether the combination logic holds up.7 min readMetabolic healthMOTS-c for athletic performance and the exercise mimetic questionYou're thirty-eight, or forty-two, and the training hasn't changed that much. You're still putting in the hours. You're still doing the things that worked. But the baseline has shifted — the recovery takes longer than it used to, the metabolic flexibility that let you run hard and bounce back has grown sluggish, and the same effort that used to leave you feeling sharp now leaves you grinding through the back half of the week. Your body has changed the math on you without telling you what changed.8 min readMitochondrial healthWhat people are reporting about MOTS-cThis article summarizes experiences reported in public online communities including Reddit, longevity forums, and discussion boards. We are not advocating human use of any compound discussed here. Many of the peptides discussed are not FDA-approved for the uses described, and some are explicitly not approved for human or veterinary use. What follows is a synthesis of what people have reported, presented to give readers context on the public conversation — not as guidance, not as evidence of safety or efficacy, and not as a recommendation. Decisions about any compound should be made with a qualified prescribing provider after a full medical evaluation.7 min readMetabolic healthMOTS-c and insulin sensitivity — what animal research has exploredThe weight that arrives in your forties doesn't announce itself as a metabolic problem. It shows up as pants that fit differently, a number on the scale that moves stubbornly in one direction despite the same habits that kept it stable for years, an afternoon energy dip that coffee doesn't fix the way it used to. You eat more carefully and exercise more deliberately and the situation improves slowly if at all, or it cycles — better for a stretch, then quietly worse. Nobody says "insulin resistance" until something dramatic happens. Before that, the story is just: your body isn't responding to what worked before.6 min readMitochondrial healthMOTS-c in longevity stacks — what's being exploredThe longevity protocol world has a stacking problem. Not a problem in the sense that stacking is necessarily wrong — combining compounds that address different mechanisms is conceptually sound in medicine — but a problem in the sense that the reasoning often runs backward. The aspiration comes first. The compounds follow. The mechanism gets retrofitted to justify what was already going to happen. When you're dealing with compounds that have thin human evidence and strong preclinical data, this pattern matters enormously, because it's the difference between a rationally assembled protocol and an expensive bet dressed up in biological language.7 min readMitochondrial healthMOTS-c in plain English — mitochondrial-derived peptides explainedYour mitochondria are not quiet. They're not just burning fuel and staying out of the way. They're running a continuous metabolic read on the cell's energy state and broadcasting updates — and those updates, it turns out, include peptides that circulate through the body and communicate with tissues that have nothing to do with where the mitochondria physically sit. MOTS-c is one of those peptides. Understanding what it actually does requires starting with what the cell does when energy runs low.8 min readOrigins and discoveryMOTS-c — the peptide your mitochondria write themselvesIn 2015, a research team at the University of Southern California published a paper in Cell Metabolism that quietly changed the way biologists had to think about the mitochondrion. The paper was not loudly announced outside specialist circles. It didn't generate the cultural noise that cancer immunotherapy or CRISPR news generated that same year. But what Pinchas Cohen, Changhan Lee, and their colleagues described was a genuine reclassification — a finding that required updating a story about cellular biology that had been told, largely without revision, since the 1960s.8 min readCompounding and compliancePeptide stacks for longevity vs performance — different goals, different combinationsYou're 48. You train four days a week, you sleep reasonably well, your labs are broadly fine, and you've been reading about peptides for six months. You have a list of compounds and no coherent framework for how they fit together. Someone told you BPC-157 was good. Someone else said Epitalon was what you actually needed. A forum thread convinced you that Ipamorelin plus CJC-1295 was the move, but then another thread contradicted it with an argument about IGF-1 and cancer risk that you haven't been able to shake. The problem isn't information. You have too much information. The problem is a framework for understanding what you're actually trying to do.10 min readMetabolic healthPeptides vs fasting and fasting mimetics — overlapping or distinct?You're trying to build a metabolic optimization approach and you've arrived at a crossroads that nobody's mapped very clearly. On one side: fasting, in its various forms, with decades of research and a straightforward mechanistic story. On the other side: a collection of compounds — some pharmaceutical, some peptide, some nutritional — that appear to produce some of the same effects without requiring you to stop eating. The question isn't really which one is better. The question is what they're each doing, where they overlap, and how to think about the whole category before you decide what belongs in your life.9 min readMetabolic healthThe cardio that feels harder — when the same effort registers as more workYou've been running this route for three years. You know it — the grade on the first half-mile, the way the second mile opens up, how long the hill takes when your legs are fresh. The pace that used to feel like an easy conversation now has you monitoring your breathing. Your heart rate at what you've always called an easy effort is running ten, sometimes fifteen beats higher than it used to. You finish and the recovery takes longer. You used to run on Tuesday and feel ready again by Thursday. Now Friday is more honest. The bike ride you've done weekly all summer requires a day more. Your body is technically doing the same thing. It doesn't feel the same at all.8 min readMetabolic healthThe energy crash after meals you didn't have beforeAn hour after lunch — sometimes forty-five minutes — a wall comes up. Not tiredness exactly, though it presents as tiredness: the eyelids that get heavy, the mind that loses its sharpness, the body that would like, very much, to be horizontal. It's the quality of energy that was there before lunch that is simply gone, and a certain glueyness has replaced it. It's not every meal. It's most meals with meaningful carbohydrates — the sandwich, the pasta, the grain bowl that seemed like a reasonable lunch. And it's not because you're sleeping badly or because you're working fourteen-hour days, though you might be doing both of those things. It's happening on the reasonable days too, at reasonable lunches, at the unremarkable midweek moments when you have no particular reason to be running low. Your doctor's response, when you mention it: everyone gets a bit sleepy after lunch, that's normal, maybe cut back on the coffee so the afternoon isn't a crash from caffeine. Which doesn't address what you're actually describing at all.8 min readAnti-aging and cellular healthFeeling like you're aging faster than your peersThere was a reunion — or a photo, or a run into someone from a former chapter of your life — and the comparison was unavoidable. They looked the same. Roughly the same as a decade ago, the same as your memory of them. You looked at yourself in the same context and recognized that you don't. The skin has changed more. The hair is thinner, or grayer, or both. The body composition has shifted in ways that feel less like normal variation and more like drift in a direction you didn't choose. It might have been a single photo. It might be a persistent, private sense that the gap between your chronological age and how you look and feel is not running in your favor.8 min read
