Are Testosterone Boosters Natty? (The Surprising Truth!)

Many gym goers take testosterone boosters with a goal of increasing their T levels.

But can you take testosterone boosters in natural bodybuilding competitions, and are they classed as natty?

Are Test Boosters Natty?

Testosterone boosters are natty since they’re allowed to be taken in natural bodybuilding competitions. But a small subset of bodybuilders believe that to be natty, you can’t take any supplements.

In this post, we will define what natty means, whether testosterone boosters are steroids, whether testosterone boosters are banned, and much more.

What Does Natty Mean?

‘Natty’ is a slang term used by bodybuilders to describe something/someone as natural.

But depending on which bodybuilder you speak to, natty can mean different things.

Some people think that no supplements are considered natty.

But to me, this makes no sense.


Well, many supplements like amino acids and caffeine are natural found in food and drink.

So you can’t really call something unnatty if it’s part of what humans consume on a daily basis.

On the other hand, most people agree that to be natty, you don’t take any banned PEDs (Performance-Enhancing Drugs).

I.e., your physique is achieved solely by diet, resistance training and supplements that are approved by the world anti-doping agency.

Are Testosterone Boosters Steroids?

When discussing steroids in the weightlifting community, people are usually referring to anabolic steroids, like Deca, Dianabol and Anadrol.

These are synthetic versions of male testosterone, which help increase size and strength.

Whereas testosterone boosters are supplements made from different natural herbs, like tongkat ali and ashwagandha.

So no – testosterone boosters aren’t steroids.

Are Testosterone Boosters Drugs?

Well, it depends on how you define the word drug.

According to

A drug is a chemical substance used in the treatment, cure, prevention, or diagnosis of disease or used to otherwise enhance physical or mental well-being.

So by their definition, you could argue that testosterone boosters are a drug since they enhance physical well-being.

Whereas define a drug as:

A chemical substance, such as a narcotic or hallucinogen, that affects the central nervous system, causing changes in behaviour and often addiction.

By this definition, testosterone boosters aren’t a drug as they don’t affect the central nervous system.

Are Testosterone Boosters Banned Substances?

Testosterone boosters aren’t banned by the 3 large sport’s governing bodies – the World Anti-Doping Agency (WADA), the International Olympic Committee (IOC), or the NCAA.

4 Examples of Unnatty Bodybuilding Substances

Ok Robb… So if testosterone boosters are considered natty, then what isn’t?

I’m glad you asked!

Here are 4 substances that are most certainly not natty.

Hormone Precursors

The WNBF (World Natural Bodybuilding Federation) has banned hormone precursors like DHEA, which converts into testosterone in the body.

Growth Hormones

Growth hormones include Insulin, HGH (Human Growth Hormone) and IGF-1 (Insulin Growth Factor-1).

These are also banned by the WNBF.

Anabolic Steroids

There are many different varieties of anabolic steroids, including:

  • Deca
  • Anavar
  • Anadrol
  • Winstrol
  • Dianabol

They are all banned from natural bodybuilding competitions as they help spike your T levels.

Interestingly, Testosterone itself is banned in most forms.

(It’s often sold as gels, cream and patches.)


SARMs are becoming more and more popular amongst bodybuilders.

Unfortunately, SARMs are not natty as you can’t take them in natural bodybuilding competitions.


Wrapping up, most people would class testosterone boosters as natty.

They’re made from natural herbs and include no anabolic steroids.

Well, that’s all for today folks!
