When I was younger I had no idea what I wanted to do with my life. But I decided to go to university to try and figure things out. I enrolled in a business course because that seemed like the best thing to do at the time. 

University is supposed to be about studying for exams and getting good grades. But for me, it consisted mainly of drinking and missing early morning lectures.

Once I graduated, it was time to become a serious adult!

I was drawn to finance as a career for a few reasons. It was prestigious, well-paid and speaking multiple European languages made me employable, and I ended up working in London for large multinational banks. 

Working in finance was interesting, but was stressful. Commutes, client dinners, long hours, early mornings, lack of sleep, lunches at your desk, and pressure of the job takes its toll on you.

I saw this firsthand with people who were extremely successful and made lots of money, but their health was in tatters, and I was determined not to let this happen to me.


I have always been passionate about health & fitness and had spent years experimenting with different diets and exercise programs, and refining my knowledge. 

By the time I was in my late 20s, I felt like I was in a good place – I was in good physical health, I didn’t drink, smoke or take drugs. To a large degree, living a healthy lifestyle helped counteract many of the negative aspects of working in finance.

Everything was going great for me until I took a blood test at the age of 28 years old, where I discovered I had the testosterone level of an 80 year old man! It turned my world upside down and changed the trajectory of my entire life. 

Given how diligent I was with my health, the result took me completely by surprise. Once the shock wore off, I reflected and it was apparent how much low testosterone had impacted my life:


I battled anxiety virtually all day every day. I felt depressed most of the time, and no matter what I tried I couldn’t seem to shake it. In addition, I struggled to make any meaningful progress in the gym, despite training very hard. And my sex drive was non-existent.


Little did I realize that these were all hallmark symptoms of low testosterone. 

After much research and soul-searching, I decided to undergo testosterone replacement therapy (TRT) at the young age of 28. While it was a drastic step, I felt it was necessary for me. 

Within weeks I began to notice the positive effects of optimal testosterone levels. I began to feel energetic and the constant brain fog I felt had disappeared.


My anxiety and depression had lifted, and I no longer had to fight a running battle with myself to manage my emotions. Being much more positive and optimistic felt like my natural state of being.


My sex drive returned to a normal, healthy state, and I began to see progress in the gym once again.

While it was traumatic and difficult at first, I am thankful for the experience because it opened my eyes to many things.


Above all, it made me realize that testosterone is crucial to your health as a man. And when it's low, you’ll feel like a shadow of your former self. 

I’m honest, though, if I knew then what I know now, I probably wouldn’t have undergone testosterone. 

I chose to undergo a lifelong medication and be dependent on exogenous testosterone for the rest of my life, because I felt I had no other choice.

It was a permanent solution to a temporary problem.


This opinion has been reinforced not only through my own experience, but also that of my clients. 

I work with guys who tell me they took testosterone hoping it would help them feel more energetic, get refreshing sleep and boost their sex drive. 

After all, it’s testosterone, right?

They sometimes see an improvement for a few weeks or months, but it’s often short-lived because they never address the issues that led to their lethargy, low sex drive and brain fog in the first place. 

In my case, I now recognize that my low testosterone levels were probably due to stress and poor gut health. In fact, there’s emerging research that shows a link between low testosterone and poor gut health. [1,2]

My experience led to me writing my bestselling book, Optimized Under 35. I also co-wrote another book with my close friend Jay Campbell titled, Living a Fully Optimized Life

If you have low testosterone, chances are you don’t need testosterone replacement therapy.

Most men can optimize their testosterone and overall health through nutrition and lifestyle changes alone. 

Due to slick marketing campaigns from pharmaceutical companies, many men mistakenly conclude that low testosterone is the source of all their woes. When in reality, things like poor digestive health and blood sugar imbalance play a vital role. 

The problem is, most have no idea where to start with this. The Internet is full of misinformation and conflicting opinions, so trying to make sense of it all can make your head spin.

That’s where I come in.


Men reach out to be because they feel tired all the time, their sleep sucks and they wake up multiple times a night, and their libido has vanished.


So-called experts tell them there’s ‘nothing wrong’ or it’s ‘all in their head.’  The want to fix the underlying problem, instead of taking pills to help them sleep or get an erection.

I teach my clients how to reclaim their health & vitality through small, but dramatic changes in nutrition and lifestyle.


I equip them with tools that they can use for the rest of their lives, as opposed to short term quick-fixes that do nothing but mask underlying problems.
