In the Days of Effortless Health

Think back to those days when age was just a number and health was a given, not a daily concern. 

Your body responded with resilience to every challenge, and the thought of illness was for others, not you. 

Those were the days of unwavering energy, mental clarity, and a body that worked flawlessly, almost effortlessly. 

Fast forward to now: those days of relentless vitality and carefree well-being seem distant, leaving you yearning for that once unshakeable fortress of health

The Inevitable March of Time

Now, with decades of wear and tear, your once impervious system shows signs of faltering. 

The specter of diseases that impacted those you looked up to looms large. 

In this new world of unknown pandemics and lurking germs, your health isn't something you can take for granted. 

Stress from life's 'big boy' problems gnaws at you, threatening to weaken your defenses further.

Is it even possible to reclaim your prime?

Seasoned CEO of a software company — always on alert, juggling international calls from dawn, ready to engage with his team

He was previously sacrificing his body for career success, but Dr. Ryan helped him turn things around dramatically

Before working with SummaUp it would take him hours to accomplish what he now accomplishes in minutes

"Dr. Ryan's process turned me into a lifelong client."

He’s now matching his work output from his 20s and 30s, thanks to newfound mental sharpness

He is achieving the unthinkable for a 54 year old guy with the help of Dr. Ryan ($100Mn+ exit)

  • Other medical professionals had failed to find the root cause of Cara's bad moods and fatigue — they kept telling her she was "fine"
  • Her husband was getting great results with SummaUp, so she asked him if Dr. Ryan also treated women. (The answer is YES!)
  • Cara's goal was to get stronger and increase endurance so she could keep up with her kids, and still enjoy life after they grow up.
  • She's lost 15lbs and her muscle definition is like it was decades ago when she was a soccer player.
