Clinical Insights
Evidence-based writing on hormones, metabolic health, longevity, cardiovascular risk and body composition — from Dr. Luke Sorrell, MD FACP.
Semaglutide and tirzepatide lowered biological age by about two to three years in the drugmakers’ own data. What that means, what it does not, and who should care.
Read ArticleA cough after a cold can hang on for weeks. How long is normal, the eight-week line, the causes people miss (including a common blood pressure pill), and what a proper workup includes.
Read ArticleStairs are hard for everyone, and they are also a free fitness test. The signs that point to your heart or lungs, what a workup should include, and how to train so stairs get easier.
Read Article“Double the risk” of a 1-in-10,000 condition is still rare. What the semaglutide studies show, who is at risk, and what to ask your doctor.
Read ArticleHow to get TRT online with a real MD: state check, baseline labs, video visit, treatment only if indicated, follow-up labs. $250/mo + labs/meds.
Read Article“Peptide therapy near me” shouldn’t mean the closest spa. Learn MD-led telemedicine peptide care vs mills — then book a free Sorrell MD call.
Read ArticleSticker prices lie when labs and medication are missing. A cash-pay guide to midlife menopause HRT — not a transgender HRT encyclopedia.
Read ArticleCream sounds gentler than injections or pellets. Topical testosterone for women belongs after labs, history, and MD supervision — not a forum recipe.
Read ArticleMaps often returns IV lounges and med spas. A drip menu is not physician-owned longevity care with labs, indications, and follow-up.
Read ArticleWhat zone 2 means in plain cardio language, how people estimate it, and why longevity medicine treats it as habit infrastructure — not an aging cure.
Read ArticleA normal cholesterol panel is reassuring. It is not always the whole story — an ApoB test and a once-in-adulthood Lp(a) test answer questions LDL-C does not.
Read ArticleSearching for an online TRT clinic often starts with a simple worry: is this legitimate care, or a script mill?
Read ArticleA high TPO antibody result marks autoimmune thyroid risk. It is not an automatic prescription and not a diagnosis from one number.
Read ArticleMany women searching testosterone and menopause have already heard “no.” The refusal is common. The explanation is often thin.
Read ArticleAds sell inch losses. Tesamorelin expectations start with the FDA-labeled indication, then monitoring and separate cost buckets — not a photo gallery.
Read ArticleBorderline TSH with Free T4 still in range is a lab pattern. Persistent symptoms deserve a fuller workup — not self-started thyroid hormone.
Read ArticlePhoto galleries are marketing. Realistic sermorelin expectations are categories of change, candidacy, and monitoring — not guaranteed results.
Read ArticleSemaglutide is a GLP-1 agonist. Tirzepatide adds a GIP pathway. Which pen fits is a clinical decision, not a poll.
Read ArticleGLP-1 ads sell the scale. MASH is about inflammation, fibrosis risk, and metabolic health — not pounds alone.
Read ArticlePrenuvo and full-body MRI cost searches ask what elective imaging buys, and whether a scan is the same thing as longevity care.
Read ArticleA vial price is not the bill. Peptide therapy cost has three buckets: physician access, medication, and labs.
Read ArticleSearching for a peptide doctor usually means you want a named physician — not a storefront that ships vials without a monitoring plan.
Read Article“I don’t live in Texas” is the most common hesitation we hear from people shopping for telemedicine hormone care across state lines.
Read ArticleThe omega-3 index is EPA plus DHA in red blood cell membranes. A fish-oil bottle does not tell you the percentage.
Read ArticlePodcasts frame a diabetes drug as a lifespan shortcut. Longevity use is typically off-label and belongs in an MD conversation, not a gray-market cart.
Read ArticleLow energy, libido, mood, and muscle changes can overlap with androgens in women — and with thyroid, iron, sleep, and perimenopause.
Read ArticleMaps often returns med spas and IV lounges. The useful question is whether a board-certified MD is licensed in your state.
Read ArticleThere is no honest one-word answer. Safety depends on pharmacy quality, clinician oversight, what is in the vial, and whether anyone monitors you.
Read ArticleHow to reverse insulin resistance starts with labs interpreted by a physician, not another DIY checklist.
Read ArticleSticker prices lie when labs and monitoring are missing. A real TRT bill has three parts: physician access, labs, and medication.
Read ArticleA hormone optimization clinic should start with history, symptoms, and labs — not a brochure number and a same-day shot.
Read ArticleHOMA-IR estimates insulin resistance from fasting insulin and glucose drawn together. A normal label can still miss early metabolic strain.
Read ArticleFatigue, midsection weight, and wired-but-tired are not proof of broken adrenals. Sorting stress physiology from rare hypercortisolism is a clinician’s job.
Read ArticleMen on testosterone who still care about fertility or testicular support need a physician decision — not a forum schedule.
Read ArticleThe scale can move while lean mass falls. Composition — not pounds alone — is the endpoint that matters on a GLP-1.
Read ArticleGalleri and other multi-cancer early detection blood tests are adjunctive screens. They are not a diagnosis and not a replacement for guideline screening.
Read ArticleA Function Health review should separate what labs do well from the gap a dashboard cannot close: a treating physician and a plan.
Read ArticleFree testosterone vs total is the question most men ask after a normal total T result that does not match how they feel.
Read ArticleA FIB-4 score is a triage tool — not a diagnosis, not a biopsy, and not a reason to treat yourself.
Read ArticleEstrogen dominance is popular shorthand for a symptom pattern. It is not a diagnosis you can confirm from a checklist alone.
Read ArticleMen comparing enclomiphene and TRT usually want symptom relief without closing the door on biologic children. This is a decision framework — not a protocol.
Read ArticleThe DUTCH hormone test reports dried-urine metabolites. For many questions, morning or cycle-timed serum is still the right first step.
Read ArticleAisle bottles are easy to buy. Decisions about DHEA for women start with labs, history, and MD supervision.
Read ArticleA DEXA scan for body fat shows what the scale cannot: whether the change was fat, lean mass, or both.
Read ArticleA C-peptide test reflects endogenous insulin production. A single number without glucose, timing, and history is not a plan.
Read ArticleLDL cholesterol can look fine while ApoB and Lp(a) tell a different story. Here is what lab discordance means, in plain English.
Read ArticlePerimenopause is diagnosed by the story, not by a single lab value, which is exactly why it is one of the conditions best suited to care by video.
Read ArticleSixteen hours, twenty-four, seventy-two, five days: every number has a following. Only one of them has a human trial behind it.
Read ArticleTrouble falling asleep and waking in the middle of the night are two different problems with two different explanations. The second one is usually a signal being sent from somewhere else in the body.
Read ArticleTwo measurements outperform most of what appears on a standard panel at predicting all-cause mortality. Neither requires a blood draw, and almost no one is ever told their number.
Read ArticleIt can begin in your late thirties and run for the better part of a decade. Most women are told their labs are normal and sent home — because the test they were given cannot answer the question they came in with.
Read ArticleAbout one in five people carry an inherited particle that raises the risk of heart attack and aortic valve disease. It is not on the standard panel — and a normal cholesterol result does not rule it out.
Read ArticleMost people's supplement shelf is the accumulated residue of a decade of good intentions and podcast episodes. Almost none of it was ever chosen for them, specifically, on the basis of anything measured.
Read ArticleGLP-1 medications are the most effective weight-loss tools we have ever had. Used without a plan, they also take a meaningful share of the one tissue you can least afford to lose.
Read ArticleTwo people drink the same two cups a day. In one, it's protective. In the other, it tracks with a measurably higher risk of a heart attack. The difference is a single letter in one gene.
