9 Myths About Testosterone

I’m sure you’ve come across many myths about testosterone. And some of them may even have you wondering if it’s true.

As you know, people can present convincing opinions. And they will try to back it with ‘bro-science’ or something they heard or read on the internet.

The problem with that is they often lack credible sources and facts.

Well, it’s time to debunk 9 of the most common myths about testosterone and get to the real truth. Are you ready?

Myth 1: Testosterone Will Turn You Into a Jerk

testosterone makes you aggressive and will turn you into a jerk. myths about testosterone

This is probably the dumbest myth about testosterone.

If you’re already a jerk, then there’s a good chance you’ll just be a bigger jerk with more testosterone.

There’s absolutely no evidence proving taking testosterone of any source, whether prescribed from a doctor, natural test booster, or ‘off the street’ (which that’s not a smart way to go), will magically turn you into an a-hole.

On the contrary, here’s what testosterone really does (from a scientific and fact-based stance):

  • Helps you have more confidence
  • Increase cognitive ability
  • Improves mood and sense of well-being
  • Can make you more assertive

How does this work?

Elevated testosterone levels help lower cortisol levels. This is what gives you the benefits above, along with lowering stress, per mdmag.com.

The truth is most bodybuilders, weightlifters, and muscle heads you’ll meet are the nicest, most considerate, and kind people.

Myth 2: Testosterone Will Make You Fat

This is actually one of the funniest of myths about testosterone.

So let’s clear the air. Testosterone does not make you fat. In fact, it does just the opposite…

  • Allows you to pack on muscle mass
  • Makes you stronger if your goal is to lift heavier weights
  • Supports a healthy metabolism, which essentially turns your body into a fat-burning machine

Now, some testosterone boosting supplements can make you retain a little water. But there’s a tremendous difference between water retention and body fat.

So, what makes you fat? Eating the wrong types of foods, or eating too much in general!

Myth 3: There’s No Reason to Boost Testosterone

If you’re happy losing muscle, gaining body fat, being sluggish, and having the many potential health issues that come with low testosterone levels, then you’re absolutely right…there’s no reason to boost your testosterone.

There are many who are against any type of testosterone supplementation or therapy. That’s ok. Let them stay on the other side of the fence.

Here’s why you need to be concerned with elevating your testosterone levels:

  • Low testosterone can lead to a number of health issues
  • Studies show that heart disease (which is the #1 killer of men) is directly associated with low testosterone levels, per webmd.com
  • Muscle loss and fat gain (neither of which you want!)
  • Sex drive goes to crap
  • Problems sleeping (which can lead to other problems)
  • Low testosterone can also lead to depression (read my post on How Testosterone Can Cure Depression)

As you can see, there are plenty of reasons to increase your testosterone, or at least avoid having low T levels.

Many people that speak against taking testosterone or testosterone boosting supplements are either just ignorant or have had a bad experience that causes this belief.

Perhaps they were bullied by a meathead in high school or something. That sucks, but as I mentioned in Myth #1, you can’t judge the whole crew of testosterone-fueled gym rats by one bad experience.

Myth 4: Taking Testosterone Will Cause Heart Disease and Cancer

What you may hear from the uneducated is that taking testosterone will cause ailments such as heart disease or cancer.

I’m not a doctor or medical expert, so I (and probably you as well) lean on those who are trained in the field of medicine. So instead of spouting off my opinion, I’m simply going to give you some reliable sources…

  • John P. Mulhall, MD, and director of Male and Reproductive Medicine Program at Memorial Sloan Kettering Cancer Center states that testosterone therapy does not cause prostate cancer on endocrineweb.com. He does go on to say it’s important to monitor those on testosterone therapy.
  • T-Nation.com lists ‘testosterone causes prostate cancer as the first lie in their article 8 Lies About Testosterone That Need To Die (there are several references at the bottom of their article).
  • Harvard Health Publishing provides facts about how low testosterone is linked to heart disease (the opposite of the myth that it causes it) on health.harvard.edu.
  • Several studies show that there was no greater risk of heart disease in men on testosterone therapy, on mayoclinic.org.

Those are just a few of many research-backed articles debunking the myth that testosterone causes heart diseased or prostate cancer.

Myth 5: Low Testosterone is a Normal Part of Aging

myths about testosterone normal part of aging

I actually had to dig deeper into this because I used to believe this myth. It’s common to think that having low testosterone levels is just a normal part of aging and naturally happens with older men.

But further research from the Medical College if Wisconsin proves otherwise on froedtert.com.

For starters, low testosterone doesn’t discriminate with age. Imbalanced hormones can be an issue at any age and can happen to both men and women.

So what exactly causes low testosterone? Why does is seemingly decrease in most men over time?

Low testosterone is more than often caused by many changes, much of what we can control such as…

  • You used to go to the gym and lift weights, but you stopped (or you never did)
  • Your diet is filled with crappy foods (which can kill your hormones…you can read more about that in this post Foods That Kill Testosterone)
  • Your lazy and rarely do any type of exercise
  • You sit more than you used to

There can be environmental factors that impact your testosterone levels as well. But if you’re staying on top of what you can control, you should be able to maintain normal levels of testosterone.

Another major problem with the myth that low testosterone is a normal part of aging is that it keeps many men from doing anything about it. So it’s accepted, all the while their health continues to decline because of low T levels.

Myth 6: All Testosterone Boosting Supplements are Safe

No matter how convincing the supplement advertisement is, proceed with caution before you buy any supplement that claims to increase your testosterone.

Here are 3 common types of testosterone supplements (or substances) that you can buy over the counter, legally, and with no prescription:

  • Natural testosterone boosters – Most natural test boosters are actually safe. The downside is most of them are ineffective at actually raising testosterone (or really doing anything!). Aka, most don’t work.
  • Prohormones – Prohormones have continued to evolve. But they are probably the most dangerous of anything that you can buy over the counter. One of the main side effects is they’re harsh on your liver.
  • SARMs – SARMs (selective androgen receptor modulator) has similar chemical properties as steroids. With that, they also have the same potential side effects per legionathletics.com, though not as dramatic.

The moral of the story is to read the label. Actually, do more than that. Study the labels. This should be the rule for any supplement you take.

First of all, is the testosterone boosting supplement safe? Are there potential side effects? Are they worth the risk (if any)?

Secondly, are the ingredients truly effective? And don’t take the ‘backed by science’ or ‘double-blind placebo university tested blah, blah’ as gospel. Again, do your own due diligence, and make an educated decision.

Myth 7: Testosterone Will Make Your Penis Shrink

This myth about testosterone has always made me laugh. But if you have even the slightest notion that this is true, you’re going to run for the hills, far away from testosterone!

In short (no pun intended), NO, testosterone will not make your penis shrink. You’re pretty much stuck with what you have, whether that’s good or bad.

Now, taking any form of synthetic testosterone, anabolic steroids, or testosterone therapy can make your testicles shrivel, per dontcookyourballs.com.

Why does this happen?

When you’re taking testosterone, it will shut down its own testosterone production. This causes a reduction in certain cells (Leydig cells), which in turn make your balls smaller. Sperm count reduction is also in the mix here.

**This typically isn’t an issue with taking natural testosterone boosters.

But in no way does this impact your actual wanker size.

Myth 8: Loss of Muscle And Weight Gain is Not a Sign of Low Testosterone

myths about testosterone muscle loss and weight gain

This is where many people are in complete denial. Now, I’m not saying that in every single case of someone losing muscle and gaining fat that it’s a case of low T.

But make no mistake, the loss of muscle (and fat gain) is certainly a sign of low testosterone.

Just how is losing muscle and getting fatter associated with low testosterone?

Simply put, testosterone helps you build muscle mass. It also helps regulate metabolism to burn fat (and the more lean muscle you have, the more efficient your body will burn fat…so that’s a double whammy). Refer to myth #2 above.

Per an article on everydayhealth.com, low testosterone has the exact opposite effect. If you have low testosterone levels you will not be able to build muscle mass. For the same reason, you will be more prone to gaining weight.

In fact, low testosterone can cause far greater issues than just losing muscle. There’s actually potential health risks with low T levels. But understand that the loss of muscle can also lead to health problems. So it’s a vicious cycle.

So you should ensure that you are aware of the symptoms of low testosterone. Things like feeling sluggish all the time, no drive, feeling down…those are possible symptoms.

Myth 9: Testosterone Supplements are Bad For You

In Myth #6 above, I advised you to be cautious of any type of supplement that claims it can boost your testosterone. Now we’re going to talk about the flip side of that.

Some will tell you that all testosterone supplements are bad for you. But that’s accurate. Not even close.

There are some natural testosterone boosting supplements that can help increase your body’s ability to produce more testosterone. The keyword here is natural.

This is when I say, once again, make sure you pay close attention to the label. And study the ingredients!

Here are a few ingredients that are proven to be effective at naturally boosting testosterone…

  • Vitamin D – Sounds simple, but getting adequate vitamin D will have a nice impact on testosterone, especially for men.
  • Zinc – Without question zinc will increase testosterone.
  • Magnesium – Magnesium will help further promote the effects of zinc, which is why they’re often included together in natural testosterone boosters.
  • Oyster Extract – This is a promising ingredient found in the top testosterone boosters.
