Are Testosterone And Muscle Mass Linked?


So How Are Testosterone And Muscle Mass Building Linked?

Read on To Discover The Truth, It May Well Shock You! 

Are testosterone and muscle building truly linked?

People take anabolic steroids on the basis that they are and as result, they flood the body with testosterone.

This enables the body, to build muscle at a faster rate.

So based on this, the simple answer is yes increasing your testosterone does lead to an increase in muscle growth.

It isn’t as simple as that though, as synthetically increasing your testosterone levels with anabolic steroids, isn’t a true representation of natural testosterone levels that occur.

In fact , artificially flooding your body with a high amount of testosterone like this comes with a host of negative health impacts.

You can learn more about the dangers of steroids in bodybuilding here!

If you want to learn more about how to have success with natural body building check out this blog by my friend Voicu:

He will help you to achieve the body you desire and achieve bodybuilding without having to take anabolic steroids!

So what effect does naturally occurring testosterone levels have on muscle building?

Muscular Man

Numerous studies have been conducted looking at the link between testosterone and muscle building.

The outcomes of the different studies while slightly varying tell the same “story”.

That story is having low testosterone levels has a negative impact on the amount of muscle you can gain & you may in fact lose muscle mass.

On the flip side having the highest testosterone levels you can reach naturally.

Will likely see a small impact in terms of increased muscle growth but not a huge one.

Where a key difference can be found in terms of testosterone and muscle building is increasing levels from low to higher/ optimised.

So if, you suffer from low testosterone levels, you can see a big difference in terms of the amount of muscle mass you can pack on by getting your testosterone to a naturally high level.

What Studies To Check Out

Perons looking at computer screen

So I’ve referred to the results of numerous studies that have been conducted in to the links between testosterone and muscle building.

So I thought it would be useful to direct you to some of these studies, so you can have a more in depth read for yourself.

Testosterone and Muscle building study 1

Testosterone and Muscle building study 2

Testosterone and Muscle building study 3

The three studies above, give you an idea of the effects low levels & high levels of testosterone have on male bodies.

Have a read through the overviews to gain a more in depth understanding of how testosterone and muscle building are linked.

The Effect Of Low Testosterone On Muscle Mass


As we’ve mentioned above and you’ll be able to see in the studies, people with low testosterone levels tend to have less muscle mass.

They also struggle to add muscle and may even begin losing existing muscle mass.

Having low testosterone levels also leads to retaining & increased body fat.

The more body fat you’re carrying the less muscular your body looks.

Men with very low testosterone levels are often overweight or have that “skinny fat” type look to them.

How Increasing Testosterone Can Increase Muscle Mass

muscular man

Testosterone  signals for the muscle cells to increase the rate at which new muscle protein is laid down, this process is called protein synthesis.

The more testosterone your body can utilise, the more protein synthesis can take place & the increase of protein synthesis,

Over time, this increase in muscle protein synthesis leads to large & stronger muscles.

It’s not just outright levels of testosterone that dictate the levels of protein synthesis though, it is the amount of testosterone your body can utilise.

That is dictated by your androgen receptors, the more androgen receptors that you have, the more of your available testosterone can be put to use.

I’ll be putting together a couple of articles, on androgen receptors & how to increase them as well, so keep an eye out for those.

How To Know If You Have Low Testosterone

There are multiple physical and mental/ psychological signs that someone may be suffering from low testosterone.

You can find out more about these signs hereTestosterone And Health – The Symptoms Of Low T

A definitive way to know if you are suffering from low testosterone levels is getting them tested.

There are organisations that offer this, which has mainly come about due to getting these types of tests through most doctors and national health services being extremely difficult!

I’ve actually done an article on this, providing an overview of my recommended  testosterone testing service in the UK.

You can find out more about it and how these services tend to work as a whole in the below article.

Final Thoughts On How Testosterone & Muscle Building Are Linked

So in conclusion we can say that testosterone and muscle building are linked.

In fact your testosterone levels effect your muscle mass in a couple of different ways.

If your testosterone levels are low, you can experience a loss in existing muscle mass and/ or struggle to gain muscle mass.

When suffering from low levels, if you increase them naturally you can see an increase in muscle mass gains.

You can even begin to see results, where progress to date may have felt slow or non-existent.

If you have normal or moderately high testosterone levels.

You can see a minimal increase in muscle mass by naturally increasing your testosterone levels;

This isn’t the same impact you get from synthetically increasing levels by taking something like anabolic steroids.

So the main scenario in which testosterone and muscle building effect each other is when you’re suffering from low testosterone levels.

As we’ve covered having low levels leads to a lack of muscle and being able to add further muscle.

If you suspect your levels are low I suggest you check out the below article.

I always recommend getting your testosterone levels tested, which you can find out more about below.

    Thanks for the article. The correlation between testosterone level and building muscle is well explained. I have one question, however: Is there an easier way to measure your testosterone level to determine if you can benefit from an increase?

    1. Nate Stone says:

      Hi Thierry,

      Yes I’d recommend taking a testosterone test, I’ll be doing some reviews of different services available, so keep an eye out for these. You can get these from your doctor but it isn’t always easy and convincing them you need a testosterone test can be a lot of hard work in it self!

  6. SharonRPh says:

    Such a timely read in terms of the effects of low testosterone not only on muscle building which was the focus of your writing, but I was glad to see you also addressed symptoms of low testosterone.  Low testosterone (outside muscle building) affects the quality of life of many men – struggling with weight gain, inability to lose weight, sexual issues, reduced muscle mass (just in terms of being able to physically mow the grass or participate in casual sporting events), and even body mass redistribution.  Glad to see that you will address anabolic steroid doping in future writing.  A well-written informative piece that is sure to stimulate interest!

      Yeah increasing your testosterone will certainly help with losing body fat and increasing testosterone production. It also brings a number of other health benefits.

  8. Kuu says:

    Your post was very eye opening about how testosterone and muscle are truly link. The effect of low testosterone on muscle mass has really shown me why people have less muscle mass and begin to lose existing muscle mass. However, one question I have is, what can people do to increase their testosterone level and build their muscle? Thanks for the answer in advance.

  9. Quinn says:

    testosterone and muscle building how the two are Linked is a wonderful article. I myself have a high testosterone level and my muscle mass it doesn’t increase no matter what I do.

    This was a very informative article I really appreciate all the information you gave on muscle mass and why some people’s increasing some doesn’t. 

    Thank you again for this. For me to article.

    1. admin says:

      Hi Quinn,

      I’m glad you found this useful!

      If you’ve reached your peak in terms of testosterone production, it may be you need to look at training methods to increase muscle gains.

  10. Mark says:

    I like how the paragraphs are in nice easily digestible chunks. You do explain well how testosterone increases muscle growth, and show how the two are linked. However, you don`t say how someone can increase their own testosterone levels naturally, and there is little scientific background to the explanation. You do make clear a good point that there are many dangers associated with steroid use to gain muscle.

    1. Nate Stone says:

      Hi Mark, 

      I’m glad you found this useful , yeah testosterone and muscle building certainly go hand in hand. Check out the studies I provided links to in the article, they give you an overview of the studies.

  11. Mary says:


    This is an interesting post. I did know that testosterone levels are important in men for a few reasons, and one being able to build muscle. I didn’t know if the loss of muscle mass was the result in low T levels, that too is interesting. You mentioned that if your T level is low that you could boost it naturally instead of using the synthetic testosterone that is harmful to your body. How do you increase your levels naturally?

    This post was really directed at men, but women today, want to build muscle. Is there muscle mass linked to their testosterone levels? I am an older women who probably now has low levels of T, but wants to recover from surgery buy strength building, which would include building a little muscle mass. Is this still possible.?


    1. Nate Stone says:

      Hi Mary, 

      I’m glad you found it interesting, yes testosterone and muscle building do go hand in hand for both men and women, in fact women can also have a series of health issues if they have low T/ estrogen dominance and low muscle mass is included amongst them.

      There are several ways to increase testosterone production, I’d advise checking out these articles to start.

  12. Salvatore V Jenkins Jr. says:

    There was a while there where I was lifting weights and all I was seeing was definition. No matter how much I worked out I would gain no muscle mass and I guess it had to do with low levels of Testosterone.

    Now I guess the remaining question is, how does one increase Testosterone the healthy way?

    1. admin says:

      Hi Salvatore, 

      Yeah testosterone and muscle building do certainly go hand in hand and it sounds like a lack of T may be one of your issues. I’d advise starting off with your diet, these two articles will help get you going in the right direction.

  13. Dora says:

    My husband is 46 and going on 47 soon and he is always worried about loosing muscle mass.  I always tell him not to worry because he still looks good for a 46 year old.  I did hear in the past that as men get older their levels go down and I guess I can’t blame him for being worried.  I going to have my husband read your article because there is a lot of helpful information. 


    1. admin says:

      Hi Dora,

      That is around the age that a decline may become more noticeable, a loss of muscle mass is one of the major signs. The good thing is that you can reduce the decline by making lifestyle changes, yes get him to check out my site, there are and will be plenty of practical tips he can follow.

  20. Sujandar Mahesan says:

    I workout regularly. Even though I don’t take Anabolics it was really useful for me to know about Testosterone and Muscle Building. Before reading this article I did not know about all the side affects it had on human body. It was really an useful article to read about. People who are using this should definitely check this out. Thank you for writing this article and sharing it with us.

    1. Nate Stone says:

      Hi Sujandar,

      I’m glad you found it useful! 

      Yeah your testosterone levels are as important as your workout and your diet when it comes to building muscle.

  21. julienne murekatete says:

    Thank you for sharing with us this great post on testosterone and muscle building. You have explained well the relationship between the too and as I can see low level of testosterone can affect negatively the body.

    I have a question.Is there anyway to increase level of testosterone so that you recommend it to people who need to increase it?

    1. Nate Stone says:

      Hi Julienne, 

      I’m glad you found this article useful!

      Yes there are multiple ways to increase testosterone, this foods that boost testosterone production article is a good place to start.

  22. Chas says:

    What a great article! I have often wondered just how steroids work inside our bodies, now after reading your testosterone tips, I know! So, if the testosterone levels affect muscle mass, this IS one of the causes of losing muscle mass as we age? (according to your study link #2) 

    I know it happens, because I can see it happening! I noticed my butt disappearing, and some flabby lower biceps! So, I started some weight training to bring that back!  Not easy to do quickly!

    But, I can still increase my overall muscle mass with a steady workout program. I guess I need to have my testosterone  level checked and then decide if I need to boost my testosterone level. I would prefer to do it naturally. what are the best natural supplements I could take to achieve that? I would appreciate any help.

    Thanks for the great testosterone tips! I will be back for more!


    1. Nate Stone says:

      Hi Chas,

      Thank for your comments, the problem with steroids can be that they produce so much testosterone that your body stops producing it own and they can come with other side effects on top of that.

      Yes testosterone and muscle building are linked and lowering testosterone levels is one of the reason muscle mass lowers as you age, T levels start to drop after the age of about 30.

      Yeah when it comes  to building muscle, there are essentially “three pillars” these are your hormones (steroids & human growth hormone), your workout and your diet.

      Vitamin D, c, K, zinc, magnesium etc. all help increase testosterone production, I’d advise the best place to start is is this foods that boost testosterone production article, it tells you the main vitamins and mineral that help increase T an the food sources that provide them.

  23. Hi Nathan, Nathan here or Nate, like you 🙂

    As a high school teacher, I am a firm believer that teachers and students learn from each other.

    One of my students who struggles with math, informed me last week that I shoud take testosterone
    supplements to increase muscle mass. We were discussing building muscle in between math problems, and he suggested that I take a testosterone booser and something called “Creatine”.

    I did what he suggested and have been feeling a bit stronger at the gym.

    I think he was correct and my initial comment, that we all learn from each other, is correct.

    What are your thoughts?

    1. Nate Stone says:

      Hey Nate,

      Yep creating does help increase testosterone and is great for muscle building as a whole. Your student is 100% right, having a lack/ lower T can lead to reduced ability to gain muscle or even reduced muscle mass, it can also lead to weight gain and reduced fat loss. There are other things that testosterone effects, check this article out to find out more: Testosterone and health

  24. Marlinda Davis says:

    This was very interesting. I know a friend who struggles to gain muscles. He’s tried some supplements but I’m not sure what. I will forward this information to him and hopefully, he will be able to build some muscle. Do you know how if this works only for men? If women want to build muscle, do they have to take testosterone too or something else?

    1. Nate Stone says:

      Hi Marlinda, 

      I’m glad you found it useful. Yes please do pass this information on to your friend, essentially to build muscle, the three “main pillars” of your success are your diet, your hormone profile and diet. Testosterone fits in to the hormones side of things. Both men and women can increase their testosterone levels for greater muscle mass. If you want ideas on how to increase T, check out these articles on ways to increase testosterone naturally

  25. Sara says:

    Interesting topic, but with this topic my mind instantly came up with questions. Since women have lower testosterone to begin with, is it healthy for women to try to get more testosterone in order to build muscle mass? I am not interested in being a body builder by any means, but I would like to gain more muscle. Do you know of a way that women can increase hormones without affecting their hormones in a negative way?

    1. Nate Stone says:

      Hi Sara, 

      Yes women do naturally produce less testosterone (men produce approximately 20 times more). Yes women can naturally increase testosterone as the majority of people (men and women) have lower testosterone production than they should do.

      If you increase your testosterone naturally, that should work for gaining more muscle without interfering with your overall hormone profile. I suggest starting out with these foods that boost testosterone production articles 

  26. Selenity Jade says:

    Interesting article! I was aware testosterone levels helped men build muscles (as is kind of obvious if you think about it, women aren’t as strong physically as men, in general, without serious effort). I was not aware it could lead to a struggle building muscle or keeping muscle! It’s obvious, now that your article pointed this out though. I have never given it much thought, but it might be a good idea for men struggling get their testosterone levels checked. 

    I might suggest this article to a very good friend of mine the next time he brings up his struggles He’s mentioned certain things often enough throughout the past few years. Being a possibly sensitive subject, I am going to wait until he brings it up again. I don’t know. I wouldn’t hesitate mentioning to my husband or something, but a friend, that’s a little trickier. I’ll give it some thought. Anyway, thank you! 

    1. Nate Stone says:

      Hi Selenity, 

      Yeah, a lot of men are low on testosterone, so getting your levels tested to find out if they need looking at increasing is certainly worthwhile. I’ve put together an article on this, you can check out my home testosterone test article – Yeah low testosterone can be an awkward subject, next time your friend brings it up, suggest they check out this article on Testosterone And Health – The Signs of Low Testosterone

  27. Sondra M says:

    First, I feel silly as a female reading about a topic that I have always thought was a guy issue.  Yet, I have wondered if testosterone, or lack of, affects females also.  As we age, we too have more challenges keeping “adequate” levels of muscling.   I was thrilled to see other females leave comments also.  I noticed that you left some links to foods that would naturally increase testosterone.  I am very interested in reading it.   Since a lot of us females cook for the men in our lives, females should know what kinds of foods help.   Yet without reading your list, I can’t name a single food on it.   Not good for the males that we are cooking for….    Thanks for the information. 

    1. Nate Stone says:

      Hi Sondra,

      yes women need testosterone as well; and like a lot of men they have lower T levels than they should in a lot of cases as well. Yeah check out these foods that boost testosterone production articles for ideas.
