Jim LaValle is one of the world's leading authorities in this field, serving as Chair of the International Peptide Society and Co-chair of the American Academy of Anti-Aging Medicine, making him uniquely qualified to explain what the science actually says. Whether you're interested in longevity, performance, recovery or healthy aging, this conversation will help you understand what's proven, what's promising, and what you need to know before spending your money on the latest peptide trend.

For 50 years we've been told nitrates and nitrites in food are dangerous. Dr Nathan Bryan says the science never backed that up — and the real damage is coming from somewhere else entirely.

Dr Nathan Bryan is one of the world's leading nitric oxide researchers. Over more than 25 years he's published 100+ scientific papers, holds dozens of patents, and built multiple biotech companies around a single molecule that affects your heart, your brain, your energy, and how fast you age. He's the founder and CEO of Bryan Therapeutics, developing nitric oxide-based treatments for heart disease, Alzheimer's, and chronic wounds.

In this episode, we get into:

• What nitric oxide actually is, why your body needs it, and how to increase it naturally
• The research showing nitrates and nitrites in food are not the villains they've been made out to be
• Why fluoridated water, regular toothpaste, and antiseptic mouthwash may be doing more harm than good
• What's driving Alzheimer's disease — and the case for it being preventable, even reversible
• The everyday habits worth cutting if you want to live longer, healthier

If you've ever flipped a pack and wondered whether the warnings on it actually hold up, this one's for you.

Roland Peralta co-founded Nutrafol — a dermatologist-recommended hair growth brand that became a billion-dollar market leader. But the origin story starts somewhere most people don't expect: broke, unwell, and searching for answers.

In this episode, Vee sits down with Roland to trace the full arc — from financial struggle and a personal health crisis, to building one of the most recognised names in hair wellness. They go deep on the science behind hair loss and greying, the mindset required to build extraordinary things, and the purpose-driven work Roland is leading now through The Root Cause Project and WHEN Justice.

One of the most honest founder conversations we've had on this show.

We cover:→ The Nutrafol story - how a health crisis became a $1B brand→ The science of hair loss, thinning, and grey hair→ What financial rock bottom actually feels like (and what it forces)→ Mindset, resilience, and building from a place of purpose→ The Root Cause Project, Kama Flight, and WHEN Justice.

Are GLP-1 medications like Ozempic, Mounjaro, Wegovy, and Retatrutide a genuine breakthrough — or are we sleepwalking into a health crisis? In this episode, we sit down with Dr. Sam Zand, a double board-certified physician and certified Obesity Medicine specialist, to get an honest, science-backed answer.

Dr. Zand is the Medical Director of Evolve Longevity Clinic in Miami, where he works with high performers to optimise body composition, metabolic health, energy, and longevity. He's seen firsthand what these medications do — and don't do — and he's not here to sell you either direction.

In this episode we cover:

→ What GLP-1 medications are, how they work, and who they're actually for
→ The real side effects of Ozempic, Mounjaro and Wegovy — including muscle loss, Ozempic face, and becoming skinny-fat
→ Why GLPs don't work for everyone — and whether you can out-eat them
→ How to protect your muscle mass and body composition while on GLP medications
→ The effect of GLP-1s on the brain — and their emerging role in treating addiction
→ GLP microdosing: what it is and why some patients are doing it
→ Long-term use: how long do you actually need to be on these medications?
→ Whether decline is an inevitable part of ageing — and what the science actually says

This episode is for you if:
→ You're curious about GLP-1 weight-loss medications but don't know where to start
→ You're already on Ozempic, Wegovy, or Mounjaro and want to understand the full picture
→ You're concerned about muscle loss, body composition, or long-term health impacts
