Are Testosterone Boosters Really Safe? – The Clarification

Various testosterone booster pills and supplements

Yes – they are completely safe to use for healthy male adults who have no allergies or pre-existing medical conditions.

It is only unsafe when the pure hormone form is used as a part of Testosterone Replacement Therapy. You can read more about these side effects in an article by the Cleveland Clinic.

But that is to treat certain medical conditions like hypogonadism or chronic low levels of this hormone.

Athletes and bodybuilders, on the other hand, NEVER use the pure hormone form, as all the sports nutrition supplements contain only natural herbal ingredients and various minerals and vitamins. They do not include the pure hormone form at all, neither natural or synthetic!

However, as with any supplement in the world – most ingredients are unsafe if used improperly and at extremely high doses.

This means that if you take too many testosterone booster pills, too frequently – you will experience various unwanted and potentially harmful side effects!

Also, as with many other supplements, it can’t be used for very long periods of time and is meant to be cycled.

That’s because some of the ingredients contained in this type of supplement have side-effects that could be problematic if excessively used.

For example, Ginger, an ingredient widely used in test booster products, is known to have various benign but very undesirable side effects associated with prolonged usage, like diarrhea, heartburn, and various stomach discomforts.

Many other ingredients contained in this type of product have similar undesirable effects if used for too long, and some even lack known effects, as their prolonged use hasn’t been researched enough, so it would be prudent to cycle them.

Here are the main ingredients usually found in test booster supplements:

We will discuss the main possible side effects in detail below!

The 5 Main Side Effects of a Testosterone Booster

The side effects of Testosterone booster pills

If it’s used incorrectly, this supplement can definitely harm you.

There are many potential minor side effects of testosterone booster supplements, but here are the 5 biggest ones:

Higher Risk of Injuries

Natural Testosterone Boosting Supplements can help a bodybuilder or athlete rapidly increase muscle mass and lose weight.

Sadly, it does nothing to enhance the strength of various tendons and ligaments. As a result, tendon injuries, muscle tears, and ligament ruptures are very common among athletes who consume these products and don’t take extra care of themselves.


It’s the most frequently reported side effect of testosterone boosters.

It happens because certain ingredients when overconsumed, over-stimulate the activity of sebaceous glands inside the skin, making the skin more oily and susceptible to acne.

Other exacerbated skin conditions include swelling of certain parts of the body, itching, rashes, and hives.

Respiratory Problems

When taken too much, certain ingredients in test boosters can cause breathing difficulties and chest tightness, as well as sleep apnea!

Sleep apnea is also an incredibly common side effect. It is a sleep disorder that causes breathing pauses and loud snores during sleep.

Behavioral Changes

When your testosterone levels increase, it can enhance any existing aggressive behaviors and tendencies.

This mostly happens to people who have various pre-existing mental disorders or hidden mental illnesses and can cause difficulties with anger control, temper and so on.

It can also bring on feelings of anxiety and cause depression when used for extended periods of time at high doses.

Kidney Failure

Research on long-term use and health effects shows that prolonged use of T-boost supplements has an adverse effect on kidneys, which can eventually lead to renal failure.

We say it again – extended periods of use of this supplement, for example, 6 or 12 months without cycling, has a very high chance to overload your kidneys and cause them to fail!


These were the main and the biggest side effects.

There are, of course, many minor ones, associated with over-consumption of certain ingredients present in this type of supplement. That’s because each of the ingredients has its own list of various unwanted effects that can happen to people who take too much or are too sensitive to them.

The minor side effects include:

• Very slight testicular pain, due to the fact that glands have to work extra hard to produce more hormones and semen.

• Increased sweating, because the Apocrine glands tend to produce more sweat, the higher the testosterone level is in the body.

Allergies and sensitivity to various ingredients contained in such products frequently cause nausea, vomiting, dizziness, stomach aches and loss of appetite.

• Enlargement of the prostate, increasing the frequency of urination and thinner urine streams are also a side effect of prolonged use.

Finally, women should not take natural testosterone boosters under any circumstances, unless explicitly told by their doctor!

That is because, in women, supplementation of this hormone causes side effects like increased risks of breast cancer, enlargement of the clitoris, and also the development of various male characteristics, including more body and facial hair, as well as a deeper voice!

So unless health care professionals specifically tell a particular woman that they have to increase the levels of this hormone in the body – they should completely steer clear of these products and do not use them!

Women should instead look towards products like the best pre-workout for women and also the best fat burners for women.
