Sleep and recoveryAnxiety and sleep peptides compared — Selank, DSIP, oxytocin, low-dose SermorelinYou don't fall asleep so much as lie there cataloguing. The ceiling, the ambient hum of whatever your brain decided is unresolved, the fact that you know you need to sleep and that knowledge is precisely what's making it harder. You wake at 3 a.m. for no external reason and then spend an hour not-quite-conscious, not-quite-asleep, circling. The next day arrives already thinned out and the anxiety that kept you up is worse for the sleep debt, and the sleep debt is worse for the anxiety. The loop has its own particular logic and it's immune to basic advice.9 min readSleep and recoveryThe chronic traveler — peptide and recovery considerations for life across time zonesYou boarded a flight on Tuesday morning and another one Thursday evening. The week before that you were in two time zones in four days. You have status on three airlines and you've stopped tracking which city you woke up in without checking your phone first. You function. You give the presentations, you run the meetings, you make the decisions. But something in the background of your physiology has been running at a deficit for so long that you've stopped noticing what normal feels like. The energy management is constant. The coffee is structural. The first night in a new time zone is always worse, and the recovery at home never quite completes before the next trip begins.9 min readCompounding and complianceCycling peptides — when to come off, when to stay onSomewhere in the online conversation about peptides, "cycle" became a universal instruction. Take it for twelve weeks, take four weeks off. Or five weeks on, two weeks off. The specific numbers vary, but the underlying assumption doesn't: everything needs to be cycled, and cycling is what keeps it working. If you believe that, you'll apply it uniformly, which means you'll cycle things that don't need cycling and fail to cycle things that do. The rule sounds responsible. It's actually a blunt instrument applied to a situation that requires precision.8 min readRecovery and inflammationFibromyalgia and the peptide conversation — beyond duloxetine and pregabalinThe pain doesn't have a location you can point to on an X-ray. It moves. It's in your shoulders in the morning, your hips by afternoon, your jaw and the base of your skull at night. You wake up feeling like you slept on concrete regardless of the mattress. Your body registers touch that shouldn't be painful as painful — a hug that hurts, a waistband that feels like a wire. And layered over all of it is a fog so consistent it starts to feel like your baseline, a cognitive slowness you've quietly stopped mentioning to people because the look you get in return isn't useful.9 min readSleep and recoveryGrowth hormone and the slow-wave window — why sleep depth matters more than durationYou're in your forties and you train hard. You used to recover in a day. Now it takes three, sometimes four. You haven't changed much about how you train, and nothing obvious in your life has gotten worse. The soreness just lingers longer. The energy that used to be there by Wednesday morning now shows up, if it shows up, on Thursday. You sleep seven hours. Sometimes eight. And yet something in the repair cycle has gone quiet.8 min readRecovery and inflammationThe masters athlete recovery wall — what changes after 40 that training won't fixYou're running the same mileage you ran at 38. The workouts are the same. The effort feels the same — if anything, more deliberate, more disciplined, more earned. But Tuesday's track session is still in your legs on Thursday, and the Thursday run leaves a tiredness that used to clear by Saturday morning and now sometimes doesn't clear at all. You add an extra rest day. You adjust the training plan. You read everything you can find about periodization and recovery windows, and you try most of it, and the plateau holds. The body that used to absorb training stress and convert it into adaptation is now absorbing training stress and accumulating it.9 min readGrowth hormone and recoveryMK-677 vs injectable GH secretagogues — the decision treeThe syringe sits on the bathroom counter at 9 PM. You've done the research. You've talked to a prescribing provider. You're starting a GH secretagogue protocol and the question that was easy to avoid in the abstract is now concrete: do you inject this, or is there a reason to consider the oral option instead? The mechanism overlaps. The goal is similar. The biology diverges in ways that matter, and the practical trade-offs are real enough that the choice deserves more than a convenience calculation.8 min readGrowth hormone and recoveryThe 'more GH = better' myth — why pulsatile vs sustained mattersThe logic feels airtight. GH declines with age. The things GH supports — lean mass, fast recovery, low body fat, good sleep, resilient skin — also decline with age. Therefore, more GH should produce more of the good things and slow the decline. The athlete who tells you GH changed everything and the longevity clinic that promises restored youthfulness are both operating from this logic. It's coherent. It's also wrong in the way that most oversimplifications of endocrine biology are wrong: not in the direction of the effect but in the assumption that more is better than the right amount in the right pattern.5 min readSleep and recoveryBuilding a peptide approach to sleep — the integrated frameworkYou've done the things. Consistent bedtime, no screens after nine, blackout curtains, cooler room, no alcohol during the week. You've tried melatonin — the large dose that didn't work, then the small dose that helped a little, then the deliberate timing that helped more. You've cut the late dinners. You've tracked the coffee. And sleep is still not the thing you want it to be. Not terribly broken, but not right either. You wake up in the night, or you sleep the hours and don't feel the recovery, or the depth is missing in ways your body knows even when the tracker doesn't catch it cleanly.8 min readSleep and recoveryPeptides for sleep — what research has explored, by what they actually doYou lie there with your eyes closed and your brain still running. The ceiling exists. You know every texture of it. The thoughts aren't loud — they're just present, a low hum that refuses to quit. Or the opposite: you fall asleep fine, and then at 3 a.m. you're wide awake with nothing particular to blame. You check your phone even though you know you shouldn't. The light stings. You're tired in a way that sleep keeps failing to fix.10 min readGrowth hormone and recoveryPicking your GH secretagogue — Sermorelin, Ipamorelin, CJC, MK-677, HexarelinYou've read enough to know that exogenous HGH isn't what you're looking for — too blunt, too much regulatory weight, too far outside physiological range for what you're trying to accomplish. You've landed in secretagogue territory, and now the confusion has moved one level deeper. Sermorelin. Ipamorelin. CJC-1295. MK-677. Hexarelin. People in serious clinical peptide practices and people on bodybuilding forums use these names interchangeably in ways that suggest they're all equivalent options, when in fact they operate through different mechanisms, have different half-lives, different side-effect profiles, and are appropriate for meaningfully different goals.10 min readGrowth hormone and recoveryWhat people are reporting about Sermorelin over monthsThis 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.8 min readSleep and recoverySermorelin in plain English — what growth-hormone-peptide actually doesYou've heard the phrase "growth hormone peptide" and you've probably pictured something adjacent to performance-enhancing drugs — the territory of professional athletes and extreme biohackers, syringe-and-vial culture, people who are trying to be something they're not. The reality of what sermorelin actually is and how it works is substantially less dramatic, and substantially more interesting, than that image.8 min readGrowth hormone and recoveryTesamorelin vs Sermorelin — when GHRH analogs aren't interchangeableThey're both GHRH analogs. They both work by binding to the growth hormone-releasing hormone receptor on pituitary somatotroph cells and prompting GH secretion. That shared mechanism makes them sound like two versions of the same thing — one perhaps newer, one perhaps stronger — and the choice between them a matter of price or availability or personal preference. That framing misses what actually distinguishes them, which matters enough to get right before a prescribing provider writes anything down.7 min read
