Testosterone and Muscle Building

Just How Crucial Is Testosterone When Bodybuilding?

Testosterone plays an instrumental role in male development from a young age. Produced by the leydig cells in the testes, testosterone belongs to the androgen class of hormones and assists with hair growth, sperm formation, growth of the genitals during puberty, sustenance of high a libido, increase in muscle protein and improved metabolic rate.

This powerful hormone is the key to building and maintaining strong muscles, increasing strength and improving endurance. Testosterone is responsible for muscle size and growth in men, and differences in testosterone levels can even explain why some people are elite athletes and others are not.


Testosterone plays a unique role in bodybuilding. When attempting to build muscle mass by weight training, the muscles must be overloaded in order to form new muscle tissue and rebuild. Therefore the more you push yourself the more the muscles overload, and the more muscle tissue is created.

Red blood cells carry oxygen to working muscles, removing lactic acid buildup as you work out, and it is believed that testosterone boosts the creation of these cells. This means that people with higher testosterone levels are able to push themselves further during workouts – as the muscles are receiving a greater amount of oxygen – and create high levels of muscle mass. This, therefore, makes optimal testosterone levels pivotal to successful bodybuilding.

Not everyone is blessed with sky high testosterone levels however; so many athletes and bodybuilders choose to boost their natural testosterone levels with a supplement or booster.

The Older Man

Fortunately, there are myriad supplements out there that work to replace and boost testosterone, making building muscle a possibility for men without naturally high testosterone levels.

These contain a number of natural ingredients to promote high testosterone levels, support performance and boost muscle growth. They do this is one of two ways: by increasing the body’s production of testosterone or by freeing up existing testosterone in the body which is bound and inactive.

Let’s explain point two – some people may already have a sufficient amount of testosterone in their system but it may not be available for muscle building as its bound by sex hormone-binding globulin (SHBG), meaning that it is in your system, but is inactive.

There are a host of products on the market claiming to boost testosterone, all containing different compounds and formulations. Not all of these are created equal, however, so it’s important to do the research and take the time to find the right one for you.
