Low testosterone got you feeling down? Well, you’re not alone.

Did you know that our cast iron grandfathers back in the 1940s had over DOUBLE the average testosterone a man my age does today? 1  2

Why is that? A lot of reasons. I have listed some of the causes of low testosterone here. But for now, let’s understand why a lot of doctors look at you with a blank stare when you say:

Hey Doc, how do I boost my testosterone?

The short answer is, Government guidelines say: It’s fine to have low testosterone.

But why? I’ll explain in a couple of paragraphs… 

There are some doctors that know why testosterone is critical for men. Like my friend, Dr Amy B Killen, MD. She said to me: “Low testosterone isn’t something we should brush off as no big deal. It’s kind of a BIG deal.”

She was talking about doctors, and that they should not brush low testosterone off. But, here we are, they do.

Dr Killen went on to say: “We know that men who have lower testosterone levels tend to have higher mortality rates in general. So all-cause mortality is higher in men with the lowest core tile of testosterone levels.

So, we’re going to see increases in things like cardiovascular disease. So heart attacks, strokes are going to go up.”

She continued… “Generally, if you have low Testosterone, increased diabetes, increased obesity, increased problems with mood disorders, depression, insomnia, anxiety, all that goes up. And then undoubtedly, sexual dysfunction.”

I thought, WTF… so why do doctors brush it off?

Well, another Dr that cares about enhancing men’s T, Dr Ken Berry, MD, said to me: “There’s a subset of the population who believe that the government understands everything you and I just said about testosterone. And they like it for men to have a very low testosterone level. Because when your T’s low, you tend to just roll over and take it. 

Dr Berry continued… “Can you imagine trying to govern a population that had optimised testosterone levels, and you were trying to force them to do something they didn’t want to do—or force them to do something just wrong—that would not go well for you if you were the government.” 

As those words were coming out of Ken’s mouth, and everything that has happened in the last 2-years, you might see how the Gov trying to control us. Stress us out, crushing our testosterone. And this leads to hypogonadism.

Are you okay with that? 

Watch this video to learn the truth and how to fix this once and for all.

My mentor Dr Jay said the same thing. You either want to fix this and get your fire back, or you just don’t understand how critical optimal testosterone is for men. 

Remember this?

After Dr Jay crawled over mountains of data and studies doing his 5-year PhD on sex hormones, he said:

✅ When men bring testosterone up, it changes everything

✅ More money in your career

✅ More creativity and energy

✅ You just feel better

✅ Nothing beats that feeling of having lots of energy throughout the day 

✅ And testosterone is a fundamental part of that

There’s no shortage of conflicting information on how to naturally boost energy and testosterone. That’s why I work with experts in this space.
