Evidence-based articles on peptides, hormones, and longevity - written by the providers and clinicians who prescribe them.
People use the words interchangeably, but they are not the same thing. One is a years-long transition of wild hormone swings. The other is technically a single day. The difference matters for how you're treated.
Both block the hormone that shrinks your follicles. Dutasteride just blocks more of it. Whether that extra suppression is worth the tradeoffs depends on where you are and what finasteride has already done for you.
The sticker prices are eye-watering and the coverage is a maze. Here's an honest breakdown of what semaglutide and tirzepatide cost, brand versus compounded, and where the real tradeoffs are.
Compounded semaglutide and tirzepatide are how many people afford GLP-1 therapy. They can be a legitimate, safe option, or a sketchy one, depending entirely on who is making them. Here's the difference.
There's no single test that says 'you need HRT.' It's a pattern of symptoms plus the right labs plus your goals. Here are the signs that make the conversation worth having, and what to rule out first.
Hot flashes are the one everyone knows. The other 33 are why so many women spend years being told their labs are 'normal' while they feel anything but. Here's the full list and the biology underneath it.
One blocks the hormone that shrinks your follicles. The other wakes the follicles back up. They are not competitors, they are a pair, and understanding why is the difference between keeping your hair and watching it go.
Transdermal GLP-1 patches are marketed as a needle-free shortcut. The molecular reality is less convenient, and the FDA has approved none of them.
The semaglutide dose escalates over months, not weeks, and that pace is the point. Here is the standard titration schedule and the reasoning behind each step.
Topical finasteride applies the same active ingredient directly to the scalp, lowering DHT where hair loss happens while reducing systemic absorption. Here is what the trials actually show.
Finasteride is approved for men only, but clinicians do use it off-label for female hair loss. The evidence is mixed and the safety rules are strict. Here is what actually matters.
The scale shifts in your forties even when your habits do not. Here is the physiology behind perimenopause weight gain and the interventions with the strongest evidence.
Supplement aisles promise menopause relief, but the evidence is uneven. Here is an honest, graded walk-through of what helps, what is mixed, and what to skip.
Testosterone is technically an anabolic-androgenic steroid, so the short answer is yes. But TRT and steroid abuse are not the same thing, and the difference matters clinically.
Women produce and need testosterone too. When levels fall, the result can be low libido, fatigue, and low mood, though diagnosis is genuinely harder than it is in men.
One drug hits a single receptor. The other hits two. That difference shows up in the trial data, the side-effect profile, and the price. Here's the honest comparison your provider should be walking you through.
If your TRT clinic runs Total T, Free T, estradiol, hematocrit, PSA, and lipid panel - that's six markers. Here's the 40+ they're skipping and what those missing numbers actually tell your provider.
$499/yr for 100+ markers and no prescriber, vs $149/mo for a thin panel and a faceless prescription. Most patients need the missing third option - and don't realize it exists.
GLP-1 medications work. They work better when paired with the metabolic workup most online clinics skip - fasting insulin, full thyroid, HOMA-IR, and a muscle-preservation strategy. Here's the framework KAYU uses.
Two minutes to the assessment. One week to your first consult. A protocol built on your bloodwork from a provider who knows your name.
