What if one of the most powerful longevity tools isn’t a supplement… but your sex life? In this episode of The Longevity Protocol, Dr. John Robinson breaks down the real epidemiological research showing that regular sexual activity is strongly associated with lower mortality risk, improved cardiovascular outcomes, stronger immune function, and better long-term hormonal health—for both men and women.

This isn’t pop psychology. It’s long-term population data. Studies like the Caerphilly Cohort Study (tracking over 1,000 men for 10 years) found that men with higher sexual frequency had roughly a 50% lower risk of death compared to those with very low activity. Similar findings appear in Swedish and Irish longitudinal studies, as well as large female-focused research like the Women’s Health Initiative (WHI), which followed over 93,000 women and found that sexually active women had a 36% lower risk of cardiovascular mortality, even after adjusting for lifestyle and health factors.

Dr. Robinson also explains the deeper biological mechanisms behind these outcomes—how sexual activity impacts oxytocin, testosterone, estrogen signaling, DHEA, inflammation markers like CRP and IL-6, and even immune defenses like IgA production. Beyond physiology, the episode explores how intimacy reduces chronic stress, improves sleep, strengthens relationships, and supports nervous system regulation—key drivers of healthspan and lifespan.

This episode also covers practical insights on frequency, age-related changes, male vs. female benefits, solo vs. partnered activity, and why sexual health is not separate from overall health—it’s a direct reflection of it. Dr. Robinson also discusses the research showing that men may benefit from weekly orgasms, and why 21 ejaculations per month has been linked to a significantly lower risk of prostate cancer.

If you want to understand the science behind why intimacy is tied to longevity—and how to protect this part of your health as you age—this episode is a must-listen.

🔥 Most People Are Eating Protein Wrong — Here’s How to Fix It

If you want to build muscle, boost metabolism, balance hormones, and age with strength, your diet must start with protein done correctly.

In Episode 38 of The Longevity Protocol Podcast, Dr. John Robinson and Dr. Cristina Bosch break down the real science behind optimal protein intake for muscle growth and longevity — not the outdated RDA numbers created in the early 1900s.

This episode is your blueprint for eating in a way that supports maximal muscle growth, metabolic stability, and healthy aging.

Why the optimal range is 0.25g per pound of bodyweight — and why eating under 20g or over 50g can reduce muscle protein synthesis.

Most people need 0.7–1.0g per pound of body weight daily.

New research shows total daily intake matters most — not timing.

🥚 Eggs
🥛 Dairy
🥩 Beef
🐓 Chicken
🐖 Pork
💥 And why vegan protein sources often fail digestive and anabolic needs.

Carb-heavy food culture, misinformation, and decades of anti-meat propaganda.

Ancestral nutrition, nose-to-tail eating, and why traditional diets were naturally protein-dense.

• Better glucose control
• Lower inflammation
• More myokine signaling
• Stronger bones
• Improved stress resilience
• Better mobility as you age

Dr. Robinson & Dr. Bosch share their exact evidence-based stack:
• Micronized Beef Protein
• YOLKED (Fortetropin)
• Creatine (10g/day)
• Leucine (2.5–5g/day)

Our Protein-Building Stack📌 CHAPTERS📣 If you found this episode valuable:🎙️ About The Longevity Protocol Podcast

In this episode of The Longevity Protocol, we’re diving into the top 3 things that truly support muscle building. We’ll cover one hormone, one supplement, and one peptide stack—and explain how each plays a role in performance, recovery, and long-term health.

Here’s what we’ll discuss:

• Testosterone & Nandrolone: Why hormone optimization matters for muscle, energy, and mood.

• Creatine: The most studied supplement in the world—and why it still works.

• CJC + Ipamorelin: How this peptide combo helps stimulate natural growth hormone for recovery and lean mass.

• BONUS: A look at regenerative therapies like stem cells for muscle and joint health.

We’ll also bust a few myths along the way:

• “Creatine is a steroid” → It’s not.

• “Hormone therapy is only for aging men” → It’s about function, not just age.

• “You need extreme training to build muscle” → Smarter strategies make the difference.

If you want to maximize your training, protect your recovery, and understand the science of muscle growth, this episode will give you the tools you need.
