Research-backed articles for biohacker-curious readers. No PhD required.
Most articles about PT-141 are about the drug. This one is about how to actually succeed using it. The medication does part of the work — the right form, the right expectations, and the right psychology do the rest. A field guide for the first three months.
Both peptides target the same growth hormone pulse. They do it differently, they're available differently, and only one of them you can actually get prescribed right now. Here's what the research describes, sorted by what your specific sleep problem looks like.
If your sermorelin instructions read like a math problem, you're not alone — the units-and-vials part trips up almost everyone. Here's how to read a typical sermorelin instruction in plain English. Your exact dose, schedule, and form live in your patient portal.
If your NAD+ instructions have you starting at one dose and increasing it week by week, that's normal — and there's a reason. Plain-English read of a typical NAD+ instruction, including the titration and the flush most people feel.
PT-141 is used as needed — taken before intimacy. Here's how to read a typical PT-141 instruction in plain English, whether you were prescribed the injection or the nasal spray. Your exact dose, form, and frequency live in your patient portal.

Hot flashes, broken sleep, brain fog, mood swings, a changing body — they're not random, and they're not in your head. Here's what's driving the symptoms of perimenopause and menopause, and the options that actually help.
Methylene blue has been around for over a century — what's new is the low-dose cognitive research. Here's what it actually does, who it tends to fit, the one interaction that matters, and how it's prescribed.
Methylene blue showed up in your podcast feed via Huberman or Bryan Johnson, and you tried to look up whether it's safe alongside your Lexapro. The internet handed you a mess of conflicting takes. Here's the honest version, including the part most articles bury about a real, documented drug interaction.

If your Oura ring keeps showing you 12 minutes of deep sleep and you've started reading about growth hormone peptides at midnight, you're in the right rabbit hole. Here's what the research actually shows about CJC-1295/Ipamorelin and sleep architecture in adults over 40.
If you've spent any time on Tressless, you've seen the combo — copper peptide solution, dermaroller, daily minoxidil. The biohacker hair-loss crowd swears by the stack. Here's what each component actually does in the research, why people pair them, and where the evidence stops.
AOD-9604 gets sold as a clever fat-burning peptide — a fragment of growth hormone that targets fat without the side effects. The truth is more boring and more useful. Here's what the actual research describes, why one cycle disappointed you, and where it might fit honestly.
If you've been a year into shockwave, orthotics, eccentric loading, and you're still feeling that first-step morning pain, you're not imagining the plateau. Here's what the TB-500 research actually shows for the kind of stuck soft-tissue problem your foot has become.
Compounded medications are not generics. Generics are not brand drugs. All three are legitimate pharmaceutical categories, but they are regulated through different FDA pathways with different standards and different implications for the patient. A clear, non-technical guide.
Selank shows up in biohacker conversations as a 'calm without the brain fog' alternative to benzodiazepines for situational anxiety — board presentations, on-camera appearances, the high-stakes conversation. A careful read of what the Russian clinical research actually describes.
If you fall asleep fine but wake at 3 AM with a racing heart and a wide-awake brain, you have company. The pattern is specific enough that it deserves a specific explanation — and the answer isn't anxiety, it's a cortisol rhythm that's quietly shifted.
If you've been a year into PT for inside-elbow pain and you've started reading peptide forums at midnight, you're not alone. An honest read of what BPC-157 research actually shows for the kind of stuck tendon problem your elbow has become.

Compounded semaglutide and tirzepatide fueled an enormous telehealth weight-loss category during the GLP-1 shortage years. That regulatory window has been closing. Here's the current state of FDA enforcement, the 503A vs 503B distinction, and the shortage framework that enabled the boom.
Senolytics — compounds that selectively kill senescent cells — are one of the most interesting emerging categories in aging biology. The research is genuinely exciting, the consumer marketing has gotten ahead of the science, and the line between promising biology and evidence-based intervention is especially blurry here.
Sermorelin is commonly prescribed off-label for body composition support, but the research timeline for what changes at 6 weeks, 12 weeks, and 6 months is more specific than most marketing copy suggests. Here's a review of what published trials have actually measured.
Off-label testosterone prescribing for women uses three primary delivery methods — compounded cream, implanted pellets, and injection. Each has real tradeoffs around dose adjustability, convenience, and the specific physiology of what's being delivered.
NAD+ precursors come in several forms — injectable NAD+, oral NMN, oral NR, and IV — and the bioavailability debate between them is one of the more technical arguments in the longevity space. Here's what the published research on tissue-level NAD+ actually shows.
Should you swallow BPC-157 or inject it? It's the most-debated dosing question in the peptide space, and the honest answer is more interesting than 'injection is always better.' Here's what the published bioavailability research actually shows about the two routes.

Copper peptides have been showing up in hair-growth marketing for years, often with claims that don't match the actual research. Here's an honest read on what GHK-Cu does for hair, why it's typically used as an adjunct rather than a standalone treatment.
Selank is one of the few peptides studied specifically as an anxiolytic without the benzodiazepine side-effect profile — no sedation, no dependence, no cognitive cost. Russian researchers have looked specifically at whether it can support patients tapering off benzodiazepines.
Search for BPC-157 dosing online and you'll find a hundred different numbers, almost all of them lifted from rodent studies and rounded for humans. Here's what the actual published literature describes — the protocols researchers have used, what the few human studies looked like, and the dosing questions still genuinely open.
TB-500 is a fragment of thymosin beta-4, a naturally occurring protein your body already uses for tissue repair. Strip away the marketing and what's left is a real, genuinely interesting biology story — actin binding, cell migration, and angiogenesis. Here's the mechanism in plain English.
GHK-Cu has been on dermatologists' radar since the 1990s. There's a real, decades-deep research literature on copper peptides for skin repair, wound healing, and hair growth — most of it solid, some of it overhyped. Here's the read on what the published evidence supports.
Selank and Semax both came out of Russian neuropeptide research in the 1990s and have parallel-but-different profiles — Selank for anxiety and immune modulation, Semax for cognitive enhancement and neuroprotection. Here's how they actually differ at the mechanism level.
TB-500 and BPC-157 get talked about as if they're interchangeable. They're not. Different molecules, different mechanisms, different injury types they actually fit. Here's the honest comparison.
Sleep disruption is one of the most common complaints in perimenopause, and the mechanism is more specific than 'hormones.' Progesterone decline removes GABA-ergic calm. Estrogen fluctuation disrupts temperature regulation. Cortisol shifts change the architecture of early-morning waking.
Metformin was the default longevity drug in the 2010s. Then Peter Attia publicly reversed on it, citing research showing it blunts the mitochondrial adaptations to exercise. An honest look at why the informed-biohacker consensus has cooled.
BPC-157 is the peptide most associated with gut healing in biohacker circles. The rodent research is genuinely impressive. The human evidence is much thinner. Here's an honest read of what the published research actually supports — and what it doesn't.
PT-141 (bremelanotide) is the only FDA-approved peptide for female desire — a central-acting melanocortin receptor agonist approved in 2019 for generalized hypoactive sexual desire disorder. Here's how it works, what the trial data actually shows, and where it fits in a thoughtful women's sexual health protocol.

Most peptides marketed for sleep miss the actual mechanism. Here's what the research says about how growth hormone secretagogues like CJC-1295/Ipamorelin actually affect sleep — and why deep sleep matters more than total sleep.
Selank is a synthetic peptide originally developed in Russia for anxiety disorders. Unlike benzodiazepines, it doesn't sedate, doesn't cause dependence, and may even improve cognition. Here's what the research says.
Peptide therapy is having a moment, and the marketing claims have gotten ahead of the science. Here's an honest assessment of what peptides actually do — and what they don't — based on the available evidence.
Peptide therapy is generally well-tolerated, but the long-term safety data is more limited than for FDA-approved drugs. Here's what we know — and what we don't — about long-term peptide use.
Patient question we hear constantly: when will I notice results? The honest answer varies by peptide, condition, and individual — but here's a realistic timeline based on what the research and clinical experience actually show.
Peptides interact with biological pathways that overlap with many common medications. Here's what to know about combining peptide therapy with prescription drugs, supplements, and over-the-counter medications.
