What Was Testosterone levels Back In The 1940s?

Do you ever wonder why professional athletes are so much more muscular than the average person? Certainly, genetics factor in. How about why some people seem to have limitless energy and enthusiasm, while others struggle to make it through the workday?

A lot of that comes down to high optimal testosterone.

Testosterone is a hormone made primarily in the testicles, but small amounts also originate in the adrenal glands right above your kidneys. It’s responsible for male characteristics like muscle mass and strength, body hair and fat distribution, sex drive, fertility and red blood cell production. 

Testosterone levels typically peak during puberty and early adulthood but slowly decline after age 30. But that didn’t happen back in the 1940s. In fact, for a man my age, 51, his average level is under 400 ng/dl 1  2

Back in 1940, these levels were double that. What happened? 

A LOT of things as you can see

By Mark Iron

One simple strategy you can start today is at the bottom of this page.

Another problem is men are becoming estrogen dominant. Yes, as science now shows, men today are being feminised by estrogen.

This study found 3, large increases in the amount of testosterone converted to estrogen under the action of the enzyme aromatase may also contribute to hypogonadism. 

If you’re reading this, the odds are good that you have a testosterone deficiency.

So why should you care about keeping your testosterone high optimal?

You may not want to be a professional athlete or spend hours in the gym every day (although if you do, testosterone can help there too!). But when men bring testosterone up, it changes everything—more money in your career, more creativity and energy…you just feel better! I don’t know any man who doesn’t want that.

If you haven’t left this too long, you can get testosterone back to the levels our grandfathers enjoyed in the 1940s.

This is not your fault, and you can fix this.

Step 1 is to eliminate endocrine-disrupting chemicals. I have a free elimination plan you can access here.

There are other natural ways to boost testosterone to levels where you feel its powerful effects.

But again, the first CRITICAL step is to remove these nasty testosterone crushing chemicals. The next is to do an extreme estrogen detox.
