The Road to Weight Mastery - Introduction
Iron Rx is a complete roadmap to IV iron therapy — blending evidence-based science with hands-on clinical know-how. You’ll learn to diagnose iron deficiency with confidence, interpret labs in real-world cases, and navigate protocols that keep patients safe. Then, step into practical infusion training: from consult to catheter, drip-rate finesse to emergency readiness, you’ll have the skills and tools to run smooth, efficient infusions in your clinic.
Iron Rx is designed as a three-part journey, taking you from solid foundations to clinical mastery.
Part 1: Theory — Build your knowledge base with iron physiology, lab interpretation, protocols, and safety essentials.
Part 2: Practicum — Put knowledge into practice with step-by-step infusion training, dosing templates, and real-world case learning.
Part 3: Advanced (Coming Soon) — Go beyond the basics with specialized techniques, nuanced protocols, and strategies for joining the top 1% of IV iron practitioners.

Guidelines
Who actually makes the cut? Decode the 2025 Obesity Canada Guide: BMI, Waist-to-Height Ratio, ethnicity-adjusted cutoffs, and why anti-obesity bias still blocks the patients who need Rx most.
History
A venomous lizard monster built a $200B drug class. The origin story your patients will ask you about and you need to know 'cause it puts it all together. Many an "aha" moment inside.
Physiology
Why GLPs win where willpower fails. Hypothalamic appetite circuits, dysfunctional dopamine, and the blunted incretin effect, explained. The MOA your patients are owed.
Side Effects
Is your patient going to go blind? Gastroparesis, thyroid cancer, suicide: separate the headlines from the math. RR and AR for every scare, rat data demystified, real-world risk in clinical perspective.
Troubleshooting
Rescue the patient about to quit at week 4. Exact Rx for nausea, reflux, urticaria, gastroparesis, pancreatitis, gallstones, doses included, no Googling at the bedside. Be confident with your plan.
Dosing & Cost
Stop overpaying and underdosing. Injection technique, expiry dates, between-step micro-titration, 2–8 °C storage, titration pacing, and the Canadian coverage map that wins approvals.
Body Comp
Weight is a vanity metric. Protect Lean Body Mass, decode DEXA vs MRI, target Visceral Adipose Tissue not the scale, and learn the body comp ratios that protect bones, muscle and predicts outcomes.
Drugs
From orlistat to Retatrutide: the full weight-loss drug arsenal, ranked. Plus Contrave, stimulants, Rybelsus, Generics, next-gen agents, and when to refer for bariatric surgery.
Tapering
Stopping is the hardest part. Rebound math from SURMOUNT-4, the Biggest Loser folly, and proven exit strategies: as-needed, yo-yo, half-dose, pre-surg start/stop.
Pediatric
St.
Diabetes
Stop.
Insulin
Stop.
MASLD
Nearly 4 in 10 adults over 45 have fatty liver and don't know it. Diagnose without biopsy via FIB-4, ELF, and MRI-PDFF, then hit the wt-loss thresholds that reverse steatosis.
Dyslipidemia
The dyslipidemia course cardiology should have written. 2 hrs untangling conflicting guidelines so you out-prescribe most specialists on ApoB, Lp(a), FH, nocebo, PCSK9i, and GLP-1 stacks.
OSA
CPAP isn't the only answer anymore. AHI severity, tongue fat as a visceral depot, and SURMOUNT-OSA: tirzepatide cut AHI by −25 to −29 events/h at 52 wk, with or without PAP.
HTN
Forget ACEi monotherapy. GLP-1 RAs drop sBP 5-7 mmHg by 68 wk, ~70% via wt loss. The other 30%? Natriuresis, RAAS suppression, endothelial repair, and lower SNS tone.
Physical Exam
What your stethoscope misses. The head-to-toe obesity exam: xanthelasma, corneal arcus, acanthosis, acrochordons, striae, intertrigo, plus everyday tools that change patient lives.

The Canadian Adult Obesity Guidelines are the definitive, practice‑changing blueprint for modern obesity care. Lauded internationally.
We read them. Every word. So you don't have to (though we'd still suggest it!).
And distilled them into clear, actionable chapters, that you can apply straight-away in practice.

Reimagine GLP1s
Statins got rebranded as "anti-inflammatory." GLP-1s are next. Here's how to stop thinking of them as weight-loss drugs and start using them like the 195-disorder lever they actually are.
IBS
IBS-C patients have measurably less GLP-1 in serum and colonic mucosa. The drug that causes constipation in some people relieves it in others. Counter-intuitive, but the data holds.
IBD
The IBD chapter your gastroenterologist hasn't read yet. 2025 Journal of Crohn's and Colitis meta-analysis, real Canadian cases, and the obstruction data that ends the fear.
Fibromyalgia
30 years of pain, gone in 10 months. Fibromyalgia. The disease you were taught to manage forever. The new evidence says you can actually treat it. 48,000 patients can't be wrong.
Migraines
Your migraine patients will tell every friend they have. CGRPs are gated by Special Authority. GLP-1s aren't. This is the chapter that builds your referral network.
Histamine
89% of MCAS patients improved on GLP-1RA in a 47-case series. The mechanism is mast cell stabilization, gut barrier repair, and lower LPS translocation, not weight loss.
POTS
The POTS chapter that makes you the only doctor in your city who knows when NOT to prescribe a GLP-1, and how to set up a proper baseline POTS workup either way.
PMOS
Every PCOS patient in your practice just got renamed in 2026. Be the doctor who already understood it was metabolic. PMOS Pam lost 60 lbs and got her cycle back in 8 months.
Pregnancy
Reproductive-aged patients are 50% of your practice. Most prescribers fumble the "what if I get pregnant" question. You won't. This chapter gives you the script.
Post-Partum
GLP-1 is already in breastmilk. Your patient just didn't know it. The chapter that frees postpartum women from the "wait until you wean" sentence they've been serving.
PMDD
This is a concise sample sentence designed to contain exactly one hundred and ninety total characters including every space, period, and letter so you can test limits
Endo
Endo patients have been told it's a period problem for 20 years. You'll be the doctor who tells them about the 23% higher CVD risk and offers something systemic.
OA
Your OA patients are stuck between Tylenol, surgery, and giving up. This chapter offers a third path that also fixes their A1c, their lipids, and their sleep apnea.
Psychiatry
Your psych patients are skipping doses because they gained 20 pounds. Stop the cycle. GLP-1s cut psych events by 40% and reverse the weight gain that drove the dropout.
Addiction
Patches treat smoking. Naltrexone treats alcohol. Suboxone treats opioids. GLP-1s treat craving itself. The first universal anti-addiction drug in history. 606,000 patients prove it.
Binge-eating
"When I went on Mounjaro, everything went silent. It was the first time in my life I experienced silence in my own head." That's the chapter. That's the work.
Neurodegeneration
Treat the brain before the diagnosis. The neurodegen chapter where the ARR is small but the implications are massive. NNT 200 over 3 years. Imagine over 30 years.
T1DM
Endocrinology hasn't caught up. Your T1DM patients will. Be the prescriber who offers insulin-sparing GLP-1 add-on, weight management, and glycemic smoothing before their next visit.
Cancer
A 1.1 million-patient US study showed lower overall cancer incidence in obese patients on GLP-1 vs matched controls, especially for skin, GI, breast, and female genital cancers.

Course FAQs
I've never prescribed a GLP-1. Will I actually be safe to prescribe by Monday?
Will I actually use this enough to justify the price?
What CE credits will I get?
I'm a seasoned ND, with tons of experience offering GLP-1RAs. Will I really learn something?
Are you abandoning me after the course?

"Weight Rx is a game-changer for NDs wanting to feel more confident and effective in their prescribing. The course style is clear, practical, and thoughtfully structured, making complex clinical decisions feel much more approachable. I would highly recommend this course for anyone wanting to implement GLP-1’s into their practice!"
- Dr. Emma Furze, ND
"Weight Rx delivers a clear, evidence-based framework that makes prescribing feel both intuitive and clinically grounded. The structured, on-demand format translates complex concepts into practical tools I can immediately apply in practice and easily refer to when I need a refresher. It’s a rare combination of concise, actionable, and genuinely engaging education that I’d recommend to any ND looking to sharpen their clinical decision-making"
