There are also various conflicting studies regarding testosterone and competitiveness among males. Typically, it’s believed that the more testosterone pumping through your veins, the more of an alpha male you are. Thankfully, Swiss researchers put paid to such outmoded thinking in a study that found that men with increased testosterone levels acted more fairly in negotiations than those with lower levels.

Not only that, but abusing testosterone supplements may even have fatal side-effects. A study in the Journal of the American Medical Association found that boosting testosterone levels may lead to an increased risk of heart attack. Meanwhile, there are growing concerns that an over-reliance on testosterone can even induce strokes. So, what’s in it for you?

Do You Need To Boost Your Testosterone?

The question to start with is whether or not you actually need to boost your testosterone levels. Testosterone has been used as a clinical drug since 1937, but with little understanding of its use. Today we know more, and many men are prescribed boosters. In fact, men’s testosterone levels are believed to have dropped 20 per cent in the last two decades to the point where one in four men is supposed to have low testosterone levels.

“Testosterone can impact almost all areas of a man’s life – people with low levels can start to experience weight gain, baldness, low sex drive and low mood,” says a GP speaking on behalf of online consultation service Push Doctor. “By trying to boost their body’s amount of testosterone, someone who suffers from low levels might see improvements in their muscle mass, libido and hair growth.”

However, according to US medical school Harvard Health, what actually constitutes low testosterone levels in the first place is open for debate. Testosterone levels in the body vary from day to day and take into account a range of temporary factors from diet to the time of day, making obtaining an objective measurement difficult. The article also warns that some general practitioners are concerned that an increase in testosterone levels can promote the growth of cancerous prostate cells in older men.
