A Modern Pharmacist

lee

Most of what gets called healthy is just normal. Normal is not the same as optimal.
I am Lee, a prescribing pharmacist working in the NHS. I also live with diabetes, so this is not theory for me. Every week I break down the tests, numbers and decisions that actually move the needle on long term health. The biomarkers I run on myself. The tests I cannot order on the NHS but wish I could. What it is really like navigating the health system as both the person prescribing and the person managing a condition every day.
No fluff. Just evidence, from a clinician who holds himself to the same standard

Sleep Explained: Stages, Efficiency and How to Sleep Better
Sleep takes up a third of our lives, and despite leaving us vulnerable for all those hours, it’s something we’ve never evolved our way out of. In this episode I explain why sleep matters and how to improve it. I start with what happens in each stage of sleep: N2 for skills and learning, deep sleep (N3) for long-term memory and physical recovery, and REM for dreaming, emotional processing and connecting ideas. I explain why sleeping 6 hours instead of 8 costs you far more than a quarter of your REM sleep. Then chronotype: whether you’re a morning lark or a night owl, how much is genetic, and how it changes with age. The second half is practical. I cover the difference between time in bed and actual sleep, what sleep efficiency means, and why falling asleep instantly can signal sleep debt. Then how to improve your sleep, from consistent wake times and morning daylight to a cool room and a warm bath, and what to avoid: alcohol, late caffeine, and relying on sleeping tablets instead of CBT-I.

AMA: Statins, Creatine, Cholesterol and Protecting Your Heart
In this Ask Me Anything episode I answer seven questions on heart health, metabolic health, medication and training: the ones I get asked most often, plus two sent in on Instagram. I start with the vitamin stack question and why testing beats guessing, with one UK exception: vitamin D in autumn and winter. Then why being young and fit doesn't mean you can skip a cholesterol check, including ApoB and Lp(a), a genetic risk factor you only need to test once. I go through the evidence on statin side effects, including the SAMSON trial, where 90% of symptoms also appeared on placebo, and a meta-analysis of over 150,000 people showing only about 1 in 15 muscle complaints in the first year were caused by the statin. I also cover whether creatine is safe and why it can make your kidney blood tests look worse than they are, whether to prioritise cardio or weights if you only have three hours a week, and how to check your blood pressure properly at home. Finally, the big one: what you can do now to protect your heart for the future.

Iron Explained: Why It Matters, Testing and Treatment
Iron is one of the most important minerals in your body, yet most people only find out they're low once they're anaemic, and that's one of the last signs to appear. In this episode I give a general overview of iron, from why it matters to how to test and treat it. I start with what iron does: 6.5% of the body's enzymes depend on it, it sits at the centre of haem in haemoglobin, and the body uses zinc instead when iron runs short. Then how much you need: we lose 1–2 mg a day and absorb only about 10% of what we eat, and needs differ for men, menstruating women and pregnancy. I cover the best food sources and the symptoms of low iron, including restless legs and craving ice. Next, testing: why a full blood count isn't enough, what ferritin, transferrin saturation and TIBC tell you, and why inflammation can make ferritin look normal. Finally, treatment: finding the cause first, why once-daily or alternate-day dosing works better because of hepcidin, why a 65 mg tablet is repaying a debt rather than overshooting, and when IV iron is needed.

Is Microdosing GLP-1s Backed by Any Evidence?
Around 1 in 7 people on GLP-1s say they've tried microdosing, so in this episode I look at whether any of it is backed by evidence. I start with what microdosing actually means. There's no official definition, and I cover why it took off, from cost to side effects to claims about inflammation, longevity and the brain. Then how people do it: using the "golden dose" left in the pen, and stretching out the gap between injections. Next, the evidence. The lowest-dose trial we have used daily semaglutide, adding up to 0.35 mg a week, which gave 6% weight loss at 52 weeks vs 2.3% on placebo. That's still above the licensed starting dose. SURMOUNT-1 shows weight loss rising with dose, and SURMOUNT-MAINTAIN compares staying on the top dose, dropping to 5 mg, and stopping, along with what happened to side effects. I also cover EVOKE, where full-dose semaglutide didn't slow Alzheimer's. Finally, the MHRA warnings on fake pens, and why you can't know what's in an unlicensed vial. My verdict: below licensed doses, microdosing remains unstudied.

Is VO2 Max More Important Than Strength?
I come from lifting, so I wanted the answer to be strength. In this episode, I go through the biggest studies on fitness, strength and mortality to answer one question: if you could only train one, which matters more for living longer? I start with what VO2 max really measures, and why a MET is based on the resting oxygen use of one man. Then the cardio evidence: the Cleveland Clinic study of 122,007 people, where elite fitness was linked to an 80% lower risk of death than low fitness, and why "being unfit is worse than smoking" misreads it. Then the case for strength, from Ruiz's bench and leg press data to grip strength across 1.9 million people. The UK Biobank head-to-head brings both together, and I finish with Generation 100, the largest exercise RCT on mortality, and why its result isn't as clean as it looks. My verdict: cardio edges it, but the lowest risk belongs to people who have both.

Heart Disease Starts Long Before the Heart Attack
Heart disease has taken another member of my family, and it's the reason I've put so much of my career into prevention. This is a more personal episode, but I didn't want it to be just my story. I wanted you to leave with something you can actually use. I start with why heart disease is still the world's biggest killer, and why most of the risk comes down to things we can change. Then I go through the autopsy evidence. Young soldiers killed in war, and teenagers who died in accidents, already had disease in their arteries. Early changes have even been found before birth. I explain how plaque builds up while the artery quietly grows outwards to hide it, which is why a normal test doesn't always mean you're clear. Finally, I go through what actually moves your risk: lowering LDL and blood pressure, getting fitter and stronger, losing weight, stopping smoking, and checking the things people miss, like family history and Lp(a). You'll leave with a simple checklist of what to know and what to test. Sources: INTERHEART (Lancet, 2004), BHF UK CVD Factsheet (2026), Enos et al.

The Steroid User Waiting for a New Heart
At 41, after taking steroids continuously since he was 18, this patient has an ejection fraction of 15% and is on the waiting list for a heart transplant. In this episode I talk through his case and use it to separate two things that often get lumped together: anabolic steroid abuse and properly diagnosed, monitored testosterone replacement therapy. I cover how supraphysiological androgens damage the heart directly through androgen receptors on heart muscle, fibrosis, RAAS activation, fluid retention, raised blood pressure, crashed HDL and a higher tendency to clot, and why his high haematocrit was only part of the story. I go through the Baggish weightlifter study, where steroid users averaged an ejection fraction of 52% against 63% in non-users, and what the TRAVERSE trial does and doesn't tell us about TRT, heart attacks, stroke and prostate cancer. We also get into haematocrit monitoring, Virchow's triad, why testosterone switches off sperm production, and the dilemma of a man whose own testosterone is unlikely to ever recover.

Does Omega-3 Reduce Inflammation?
Everyone's heard the omega-6 to omega-3 ratio talked about like it tells you how inflamed you are right now. It doesn't — and the researcher who actually invented the real alternative test says so directly. This week I go through what the ratio actually measures, the real mechanisms behind omega-3's anti-inflammatory effects (including a gene-suppression pathway almost nobody covers), and then pressure-test the three major cardiovascular trials that somehow reached three different conclusions testing nearly the same intervention. I get into why REDUCE-IT's 25% risk reduction comes with a genuine, actively-debated methodological controversy, why the seemingly better-absorbed STRENGTH formulation failed completely while revealing a real atrial fibrillation signal, and how VITAL's "failed" headline buried a 28% reduction in heart attacks. I also walk through something genuinely uncomfortable: the original reasoning behind the 8-12% Omega-3 Index target hasn't held up as well under two decades of further research as most people assume. Finally, the practical part — what to eat, what to test, and the real gap between the UK's official guideline and what the research suggests actually matters.

The Growth Hormone Peptide That Got Shelved
Two growth hormone peptides, built by two companies in the same city, at the same time, for the same condition, using the exact same natural hormone as their starting point. In July 2006, one company's trial was halted after a participant died. The other company's trial, treating the same disease, kept going. One became an FDA-approved medicine. The other is now a research-chemical bestseller that a federal safety panel formally rejected for pharmacy use just last year. This week I walk through how these peptides actually work, why two companies took completely different approaches to stabilising the same fragile hormone, and why that one event in 2006 sent them down permanently different paths. I get into why one of them became a tightly-controlled "biologic" and the other never could, what HIV-related fat redistribution actually is and why a growth-hormone peptide made genuine medical sense as a treatment for it, and the part most coverage skips: even the approved drug doesn't protect you if what you're actually buying never went anywhere near the trials that proved it works. I also cover the real physiology of how raising growth hormone affects blood sugar, and what the evidence shows if you're already starting from normal levels.

The Peptide Safety Checklist Nobody Follows
Most people asking about a peptide want to know one thing: does it work. That's not actually the first question you should be asking — and this week I walk through the checklist that should come before it, the one almost nobody follows, including plenty of people already using these products. I cover the five questions worth asking before you put any peptide in your body, then spend most of the episode on what actually determines whether it's safe: how to read a Certificate of Analysis properly, why the two most-trusted names in peptide testing aren't accredited to any recognised standard, and why the pricing structure of this industry quietly rewards vendors for skipping the tests that matter most. I also get into a recent finding that changed how I think about sourcing entirely — some of the same manufacturers producing fentanyl precursors have been pivoting directly into the peptide supply chain. That's not a reason to panic about every vial, but it's exactly the kind of thing a purity percentage will never tell you.

The Weight Loss Drug Nobody Can Legally Sell
There's a weight-loss drug right now producing the biggest numbers ever recorded in an obesity trial. It hasn't been approved by a single regulator anywhere in the world. And it's already being injected by thousands of people, sourced from vendors who have no legal right to sell it for human use. This week I explain how that's actually possible — starting with a patent-law loophole that let an unapproved molecule's exact structure become public years before its own trials even finished. I get into why licensed pharmacies genuinely can't legally compound this drug, no matter what a website claims, and I walk through the actual pharmacology behind it: how GLP-1, GIP, and glucagon each work on their own receptors, and why building a weight-loss drug around a hormone that classically raises blood sugar is a deliberate, calculated trade-off rather than a mistake. Then I get into the real Phase 2 trial data — the actual serious adverse event cases, not just the headline weight-loss percentage — and what real-world users are self-reporting on forums like Reddit, which doesn't match the clinical trial data at all. That mismatch raises some uncomfortable questions about what's actually in these vials.

BPC-157: The Peptide Everyone's Injecting, With No Real Human Data
BPC-157 is the poster child for the peptide boom, and I want to be upfront: I'm not against peptides on principle — insulin and GLP-1 medications are peptides too. What matters is how something's produced, how it's used, and whether the evidence actually supports it. This episode is me working through BPC-157 properly, using that exact standard. I start with how clinical trials actually work, since that's the real dividing line between a regulated medicine and everything else. Then I go into BPC-157's own origin story — discovered in 1989, first reported in 1993, with the discoverers' own patent filing admitting they may not have isolated one single pure compound. I cover both proposed mechanisms currently in the literature, which don't yet connect to each other, then the animal evidence, which is real but concentrated heavily in one research group. The human evidence is where this gets serious: three small pilot studies exist, all from the same investigator, covering roughly 30 people total, none controlled. I go through exactly what each one found, and why 87.5% and 80-100% headline figures don't mean what they sound like without a comparison group. Then I compare all of that to how people are actually dosing this at home, and where that convention really comes from — it isn't from any human trial. I finish with the July 2026 FDA advisory committee vote, what it actually changes and what it doesn't, and my own honest verdict on where this stands right now. Studies & Sources: Sikiric et al.

Magnesium: Do You Actually Need to Supplement It?
Magnesium supplements are everywhere right now, and I wanted to know whether I actually needed one myself. This episode is the result of about three months of genuinely digging into the evidence — not just repeating what supplement companies say. I start with why magnesium matters mechanistically: it has to be bound to ATP to function properly, and it plays a direct role in insulin signalling, which is what first got my attention. I explain why a standard blood test only reflects about 1% of your total body magnesium, and why that makes true deficiency genuinely hard to diagnose with any confidence. The centre of this episode is the absorption question. Supplement labels frequently claim up to 80% bioavailability for organic forms like bisglycinate — but when I looked at the actual controlled research, the real figures are dramatically lower, and I walk through exactly why, including a genuine flaw in how that research was conducted. I also explain "buffering" — why some supplements quietly blend in cheap magnesium oxide alongside the organic form you're paying for, and how to spot it on a label. I cover who's genuinely at higher risk of deficiency, why food supplements aren't held to the same manufacturing standard as medicines, and the one magnesium product that actually is a licensed medicine in the UK. I finish with exactly what I've personally decided to buy, and why. Studies & Sources: Attia's AMA #54 on magnesium (background source); Firoz & Graber (2001, Magnesium Research) on bioavailability; Pełczyńska et al.

Treating Hair Loss: What Actually Works
I'm going through my own hair loss treatment right now, so this episode is a bit more personal than usual. I walk through my own thinking on minoxidil and finasteride — the two main evidence-backed treatments — and why I've made the choice I have. Before we get to treatment, I cover what you need to rule out first: telogen effluvium from stress, iron deficiency, thyroid disorders, and B12/vitamin D deficiency. I also debunk the "check your mum's dad" myth for predicting hair loss — the real genetics are polygenic, not a single inherited trait. Then I get into the mechanisms: how minoxidil increases blood flow via vasodilation and why some people don't respond to it (a sulfotransferase enzyme issue), and how finasteride blocks the conversion of testosterone to DHT. I explain the genuinely strange DHT paradox — the same hormone shuts down hair growth on your scalp but promotes it on your beard and body — and why chasing a "zero DHT" target makes no sense clinically. Because this is a cosmetic rather than a life-or-death condition, I talk openly about how that should shift your risk tolerance around finasteride's side-effect profile, and why I've personally chosen to stick with topical minoxidil for now. Sources: Hamilton (1951, prevalence data via Endotext), Chumlea et al. 2004 (family history risk), Gupta et al. 2022 (minoxidil/finasteride hair count meta-analysis), Drake et al. 1999 (finasteride scalp DHT suppression data).

TRT: The Real Benefits, Risks, and When to Actually Use It
Testosterone replacement therapy is one of the most searched, most misunderstood treatments in men's health. I go through what the evidence actually shows: the genuine benefits, the real risks, the flawed studies that shaped 15 years of unnecessary fear, and exactly when treatment is justified. I start with the core diagnostic principle: the endocrine system is symptom-led, so a low number alone is never a diagnosis. True testosterone deficiency, once you require both a confirmed low level and real symptoms, affects only around 2% of men, mostly those over 60. I explain why free testosterone, not total testosterone, is the metric that actually matters, since only 1 to 4% of circulating testosterone is biologically active. On benefits, I cover the genuinely well-documented structural effects: lean mass gains, fat loss, and real increases in bone mineral density that surprised even leading researchers who assumed bone density couldn't be influenced this way. I also cover the metabolic benefits, including a 40% reduction in progression to type 2 diabetes in one major trial. On risk, I walk through the two badly flawed studies from 2013 and 2014 that wrongly linked TRT to heart attacks and strokes, including one that accidentally included women in a study meant to be all-male, and explain what the properly powered TRAVERSE trial actually found a decade later. I also cover the real prostate cancer picture, and go deep on fertility, including the mechanism behind why hCG and clomiphene work completely differently to preserve it.

Structural and metabolic benefits: Amory et al., JCEM 2004, bone density; Page et al., JCEM 2005, body composition; Snyder et al., JAMA Internal Medicine 2017, bone density and strength; Cai et al. 2014, metabolic meta-analysis; Wittert et al., Lancet Diabetes and Endocrinology 2021, the T4DM trial; Yassin et al. 2016, continuous versus interrupted TRT.

Statins, Diabetes, and Your Brain — What the Evidence Actually Shows
Statins are the most prescribed and most controversial medication on the planet. I am not debating whether they work, the evidence there is unambiguous. Instead I go deep on the two concerns patients raise with me most often: do statins cause type 2 diabetes, and do they harm your brain? On diabetes, I walk through a genuinely new mechanism discovered in 2024: statins alter specific gut bacteria, which reduces a bile acid called UDCA, which in turn lowers GLP-1 and worsens glucose tolerance. There is already a trial underway testing whether supplementing UDCA can fix this without losing the cholesterol lowering benefit. I also cover the real numbers, how many people develop diabetes per statin users treated, weighed against heart attacks and strokes prevented, and why higher intensity statins carry more risk than lower doses. On cognition, I explain why the brain being cholesterol rich does not mean statins starve it, since the brain has its own separate, protected cholesterol supply, and where the 2012 FDA warning about cognitive impairment actually came from versus what the trial evidence has consistently shown since. I also bring in the STAREE trial, published just days before recording this episode. Finally, I explain why this question just became more urgent: 2026 guideline changes now make statins a consideration from age 30, and what that means for an evidence base built on trials lasting a fraction of that exposure window.

GLP-1s Are Approved for Way More Than Weight Loss
Everyone knows GLP-1 pens for weight loss and type 2 diabetes. What most people don't know is these drugs are now licensed — or being actively trialled — for at least eight other conditions, some of which genuinely surprised me while researching this one. I sort them into three categories based on how confident the evidence actually is. The first: conditions where the benefit tracks almost perfectly with weight loss — obstructive sleep apnea, MASH (fatty liver disease), and a specific type of heart failure. The second: conditions where weight loss explains some but not all of the benefit — cardiovascular risk reduction, which is already licensed in the UK, and chronic kidney disease, where the benefit stops making sense purely in terms of blood sugar control. The third and most interesting: two conditions — a rare brain pressure disorder and alcohol use disorder — where the evidence points to a completely separate mechanism, likely involving dopamine and reward pathways rather than weight or glucose at all. I also talk through a real patient case, a 27-year-old with a BMI of 46 and fatty liver disease, and where I think this field is heading next — including retatrutide and new drugs designed to protect muscle mass during GLP-1-driven weight loss.

Insulin Resistance Is Way More Complex Than You Think
Insulin resistance gets thrown around online like it's simple. It's genuinely one of the most complex mechanisms in metabolic health, and in this episode I break it down properly using the two researchers whose work most of our current understanding is built on — Ralph DeFronzo and Gerald Shulman. I start with DeFronzo's "Ominous Octet" — the eight separate organs and tissues involved in insulin resistance, which is exactly why no single drug or intervention will ever fix it on its own. Then I go into the actual cellular mechanism: how fat builds up inside muscle cells specifically, physically blocking the pathway that lets glucose into the cell, and why your bloods can look completely normal for 10-15 years while insulin is quietly climbing behind the scenes to compensate. I cover the liver's surprising role in continuing to produce glucose even when there's already too much in the blood, why the kidney does the opposite of what you'd expect, and I share a personal example from my own continuous glucose monitor after a single bad night's sleep that genuinely surprised me. Finally, I go through what actually works: weight loss, cutting back refined carbs and saturated fat, prioritising sleep, zone 2 training specifically for improving fat-burning capacity, and building muscle mass as a genuine metabolic buffer. Studies & Sources: DeFronzo (2009, Banting Lecture, Diabetes journal); Gerald Shulman's body of work on diacylglycerol/PKC-mediated insulin resistance; classic research on brain glucose use during starvation; incretin (GLP-1/GIP) physiology; sleep restriction and insulin sensitivity research.

The Cholesterol Test That's Been Sitting There Since 1994
Two years ago I barely knew what ApoB was. Now I think it's baffling we don't test it as standard — it's been a validated, standardised blood test since 1994, it costs next to nothing, and it may be the single most accurate predictor of cardiovascular risk we have. In this episode I explain what ApoB actually measures: one signalling molecule per lipoprotein particle, meaning it's a direct count of atherogenic particles rather than a measure of how much cholesterol mass those particles are carrying. I walk through chylomicrons, VLDL, IDL and LDL, and use a water-pipe analogy to explain why particle number — not just total cholesterol — determines how much damage reaches your arterial wall. I go deep on discordance: the phenomenon where someone can have a completely "normal" LDL cholesterol result and still be walking around with a dangerously high ApoB particle count, undiagnosed and under-treated. I also explain why your standard LDL-C result usually isn't even directly measured — it's estimated using an equation from 1972 that has real, well-documented limitations, especially at high triglycerides. I go through why the usual excuses — cost, lack of evidence, lack of standardisation — don't hold up, and where I sit on my own ApoB results.

Lp(a) Levels: Do You Need to Get Checked?
One in five people carry a genetic heart disease risk factor most doctors have never mentioned to them — and I'm one of them. My own lipoprotein(a) came back so high the lab couldn't even calibrate it. In this episode I go deep on Lp(a): what it actually is (an LDL particle with apolipoprotein(a) covalently bound to it, forming a distinct and far more dangerous particle), and why it causes more damage than standard cholesterol. I cover the mechanism — how oxidised phospholipids drive arterial inflammation, and how Lp(a) mimics plasminogen to create a prothrombotic environment on top of the atherogenic one. I walk through the actual risk brackets used in the European guidelines (under 75 nmol/L low risk, 75–125 medium, above 125 high), why it's a test-once-in-your-lifetime marker since it's fully expressed by age 5, and the real hierarchy of complications — aortic valve stenosis first, then heart attack and ischaemic stroke, then chronic kidney disease and heart failure. I'm also honest about where treatment currently stands: statins don't lower it (and can slightly raise it), PCSK9 inhibitors only shift it 25-30%, but antisense oligonucleotide therapies in Phase 3 trials are showing reductions up to 98%. And I talk through my own approach — testing my dad, considering future therapies, and why I think this should be a routine paediatric test rather than something you have to go private to access.
