Peptide
Fundamentals
What peptide. When. Dose. Stack. Risk.
14 peptides. Mechanism, dosing, stacking rules, and full contraindications — taught without a commercial agenda. No product links. No brand affiliations.
After my keynote at Health 2.0 Las Vegas, I spent 40 minutes surrounded by experienced clinicians — all confronted by patients who had done 200 hours of forum research and arrived with specific requests.
Most peptide content online is commercially motivated. Most forum advice ignores contraindications. Most prescribers have never seen a Fast-Fail matrix, a stacking interaction table, or a peptide-specific bloodwork protocol.
This course delivers exactly that — in plain clinical language, built around the questions that arise in the consultation room. No supplements to sell. No pharmacy to refer you to. Just the framework.
Every peptide.
Every angle.
Each peptide is examined across dosage, half-life, cycling protocol, stacking rules, social media claims vs evidence, and full contraindications — absolute and relative.
What Are Peptides? The Clinical Framework
Receptor specificity, metabolism, routes of administration, and the four-principle prescribing framework: amplify physiology, predict adverse effects, rely on labs, titrate systematically.
Incretin & Multi-Agonist Peptides
Semaglutide, Tirzepatide, Retatrutide — dosing ladders, head-to-head comparison, and the contraindications most online guides omit.
Growth Hormone Axis & Anabolic-Metabolic
Tesamorelin, hCG, CJC-1295 + Ipamorelin — IGF-1 baseline requirements, glucose monitoring, and why cancer history changes everything.
Mitochondrial Targeting Peptides
SS-31 and MOTS-C — ferritin requirements, WADA status, and why stacking these two specifically overwhelms adaptive capacity.
Repair & Regenerative Peptides
BPC-157 and TB-500 — the angiogenesis concern, anticoagulant interactions, and what the evidence shows vs the "Wolverine" narrative.
Immune, Metabolic & Melanocortin Peptides
Thymosin-α1, KPV, SLU-PP, PT-141 — the only FDA-approved peptide for sexual function, and eating disorder risk with appetite suppressants.
Core Safety Laboratories
CMP, CBC, HbA1c, lipid panel, IGF-1, estradiol, ferritin, CK — what to test, when to test, and what thresholds change your clinical decision.
Safe-Stacking & the Fast-Fail Matrix
The golden rules, the interaction table, and the two-failure threshold that makes stacking predictably unsafe — and the safe combinations.
Full Contraindications by Peptide Class
Absolute and relative contraindications across all five peptide categories with clinical rationale for each.
Physician Disclosure, Consent & Takeaways
FDA status disclosure requirements, informed consent elements, and the mechanism-based prescribing framework.

14 peptides.
Nothing glossed over.
From FDA-approved GLP-1 agonists to investigational repair peptides — every one examined with clinical rigour, not social media enthusiasm.
+ SLU-PP (metabolic signalling & appetite modulation) also covered in full.
The course the market
hasn't produced
No commercial agenda
Every other resource in this space leads somewhere commercial. This one doesn't. No brand recommendations, no purchase links, no referral arrangements, ever.
Evidence-honest, not evidence-blind
Every peptide is accompanied by what social media claims and what the evidence actually supports. You'll know exactly where the evidence ceiling is for each compound.
The Fast-Fail matrix
No other educational resource teaches the two-failure threshold — the lab-guided safety framework that makes stacking predictably safe or predictably dangerous.
Clinically actionable
Specific thresholds, concrete bloodwork flags, real stacking rules, full contraindication tables. Built for the consultation room, not a textbook shelf.
From prescribers
in practice
Feedback from GPs, specialists, pharmacists, and health professionals who enrolled after facing the exact consultation challenge this course was built to solve.
The Fast-Fail matrix alone changed how I manage these consultations. Three patients in one week asked about peptides — for the first time I felt genuinely equipped.
The section distinguishing what social media claims from what evidence shows — for every peptide — is worth the course on its own. My patients think Retatrutide is a done deal. It isn't.
As a pharmacist I was the first clinical touchpoint for peptide questions. The contraindication tables are now open on my desktop every day.
I work in longevity medicine. The stacking interaction tables are something I wish I'd had two years ago when patients started presenting with "Wolverine stack" protocols sourced entirely from Reddit.
I enrolled as an informed patient. The course gave me vocabulary and clinical context my previous prescriber clearly didn't have.
The GH secretagogue module was worth the entire course price. I had been prescribing CJC-1295 / Ipamorelin without fully understanding when to stop based on IGF-1 tracking.
My nursing colleagues and I enrolled together. The WADA flags consolidated throughout the course were something none of us had seen anywhere else.
I had no idea stacking MOTS-C and SS-31 was a Fast-Fail scenario until this course. The interaction table is genuinely novel — I've not seen it anywhere else.

Patients are already asking. Many are already using. The prescriber who understands the Fast-Fail matrix, the stacking interactions, the WADA flags, and the contraindication tables is the most valuable person in that consultation room.

Everything in this course exists to make you the most informed person in the room.
For educational purposes only. This course does not recommend or promote any brand, nor provide a method to purchase peptides. Several peptides discussed are not approved by the FDA, TGA, or EMA for human therapeutic use. Some peptides are prohibited under WADA/USADA rules — flagged throughout the course.
