Why this matters
The protocol I use on myself — at 55, lean and 7.8% body fat.
This is not a survey of “what’s trending in longevity.” It’s the exact stack I run today — every dose, every cycle, every monitoring decision — combining therapeutic testosterone, next-generation peptides, the Klotho longevity hormone, and microdosed GLP agonists into one coherent system.
If newer compounds emerge, you get the updates. As long as you’re in the inner circle, you stay current.
New 2026 Masterclass · Jay Campbell
- You're tired of generic "biohacking" content and want clinical-grade specifics — doses, frequencies, monitoring labs.
- You're already on TRT (or considering it) and want to layer it correctly with peptides and GLP agonists.
- You're using or planning to use Retatrutide, semaglutide or tirzepatide and want to stop losing muscle while you lean out.
- You want a longevity protocol built on mechanism, not marketing — backed by 26 years of personal use.
- You're a practitioner who needs a current, evidence-based reference for your own patients.
Inside the masterclass
What you'll learn
Five compounds, walked through in detail with a full slide deck — protocols, dosing, monitoring, side-effect mitigation, and how they stack together.
01
Module One
Therapeutic Testosterone
The foundation. Twenty-six years of personal use distilled into a working protocol — for men and women.
- Why 40% of men over 45 are suboptimal — and what conventional medicine misses
- Injectable cypionate vs. transscrotal cream — when to use which
- The 150–250 mg/week dosing window and why "more" backfires
- The exact lab panel to run at baseline and 12, 24, 36 weeks
- Why most "high estrogen" symptoms aren't estrogen at all
02
Module Two
FLGR242 Recombinant Follistatin
BioLongevity Labs’ re-engineered myostatin inhibitor — the muscle-building compound Jay added 7–10 lbs of lean mass on while staying lean.
- How a 19-day albumin-binding construct changes the entire dosing model
- Beginner protocol: 2.5–5 mg every 1–2 weeks, subcutaneous
- Advanced cycling for men and women
- Why it solves the muscle-loss problem of every GLP user
03
Module Three
α-Klotho — The Longevity Master Switch
The endocrine hormone that drops 40% between 40 and 80. Mice that overexpress it live 20–30% longer.
- Mitochondrial biogenesis in heart, brain, kidney, muscle, lung
- The 10 mcg / two-week protocol — and why never to exceed it
- Vascular, cognitive and sexual function effects (within weeks)
- Electrolyte management while on Klotho
04
Module Four
Retatrutide — The Triple Agonist
The first GLP-1 / GIP / glucagon triple agonist. Jay’s microdosing protocol delivers 70–100% of the benefit with a fraction of the side effects.
- The 0.25 mg, 2–3x/week microdose blueprint
- 12–16 weeks on, 4–8 weeks off — or strategic micro-titration
- How to layer it with FLGR242 to preserve every pound of muscle
- Cardiovascular, lipid and blood-pressure effects
05
Module Five · The Non-Negotiables
Desiccated Thyroid & The Lifestyle Stack
The compounds only work if the foundation is built. The protein, training, sleep, electrolyte and supplementation rules that turn a stack into a transformation.
- Protein: 1 g per pound of goal body weight, distributed
- REM sleep targets and tracking
- DEXA / BodPod / skinfold — what to actually measure
- Resistance training: 3–4x weekly minimum
- Creatine, magnesium and EFA foundations
- How to choose a doctor who actually uses these tools

Common questions
Before you enroll
Is this for men only, or for women too?
Both. Every compound covered — testosterone, FLGR242, α-Klotho, Retatrutide — has a dosing framework for women, with the differences explained in the relevant module. Jay’s wife Monica has been on this exact stack for years.
Do I need a doctor before starting?
Yes — and Module One walks you through exactly how to choose one. Look for a physician who has personally treated men and women with hormones for at least 5–10 years and who uses them themselves. The course gives you the lab panels and questions to bring to that conversation.
What if I'm already on TRT or a GLP-1?
This course is built for you. The biggest gains for someone already on TRT come from layering FLGR242 (to add real muscle) and Klotho (for the longevity and vascular benefits). For anyone on a GLP-1, the muscle-preservation framework here is the missing piece most protocols ignore.
How long do I have access?
Lifetime. One payment, on-demand access to the recording and the slide deck forever. As Jay updates the protocol with newer compounds and refinements, those updates are added at no extra cost.
Where do I source FLGR242 and α-Klotho?
Both compounds are available through BioLongevity Labs (Jay’s company). The course includes Jay’s affiliate code JAYC for 15% off, and the sourcing checklist walks through quality and storage considerations.
