The Side Effects of Testosterone Injections for Bodybuilding

Bodybuilders who are serious about packing on real muscle and potentially even competing as IFBB pros will often go to extreme lengths to make their dreams reality. And there are few more extreme examples of this than deciding to take steroids – side effects and risks be damned!


For those who are afraid of steroids with exciting names like Anavar and Dianabol though, the idea of using testosterone injections might seem a little less daunting. After all, testosterone is already produced in the body and everyone knows what it is.

This isn’t a case of injecting some strange and foreign substance into your body. What’s more, using testosterone feels less scary because it’s prescribed by doctors. Not for just anyone of course, but if you’re suffering with symptoms of low testosterone, then your doc may just recommend you to take some testosterone. You wouldn’t get a GP recommending Anavar!

So what’s the scoop? Is testosterone any safer than using steroids? Let’s take a look at some of the side effects.

Side Effects of Testosterone Injections

If you use testosterone in an injectable format to improve muscle gains, you can expect to experience the following side effects:

  • Breast swelling (gynecomastia)
  • Headaches
  • Anxiety
  • Insomnia
  • Sweating
  • Increased hair growth
  • Numbness and tingling
  • Pain at the site of the injection
  • Scarring at the site of the injection

To understand where these side effects are coming from, it can help to look at what actually happens in the body.

Simply, when you inject testosterone, you instantly elevate your free levels of the hormone. This can help to combat low T obviously and can also help to increase muscle mass and fat burning. But of course, too much of a good thing is no good thing at all. If you increase your testosterone too much, you can put your body into disarray, as it would be for a teenager going through puberty. This can affect your mood then and it can also cause hot flushes, acne, difficulty sleeping and headaches. You remember!

At the same time though, injecting testosterone will also lead to heightened oestrogen. This occurs as testosterone is converted into oestrogen in the body after a while. This is what can lead unfortunately to breast swelling and it can also contribute to some of the hormone imbalances that make sleeping difficult and contribute to poor mood.

Low Testosterone

Ironically though, the worst side effect of testosterone is that it can lead to low testosterone. If you use testosterone injections for long enough, the body reacts by shutting down its own production. This can cause the testes to shrink and ultimately leaves you dependent on that testosterone to maintain ‘normal’ levels. This is why doctors can be reluctant to prescribe HRT unless the patient is experiencing serious side effects already.

As you can see then, testosterone injections are far from being a safer alternative to steroids. They carry all the same risks and are just as illegal. The only safe and natural way to increase testosterone is through training, diet and supplementation with products like Testo Max from Crazy Bulk. Testo Max is one of the most powerful testosterone boosters for bodybuilders. It’s supposed to be twice as powerful as most of the other competing brands on the market.
