10-Best Testosterone Boosters

Testosterone is a crucial hormone for men. It’s involved in muscle building and fat burning, and also affects things like mood, energy, and sex drive. Testosterone levels often fall into decline, especially in men past their 40s. This leaves a lot of people looking for the best testosterone boosters.

Some men with low levels of testosterone get hormone replacement therapy. This involves the use of gels, patches, or injections containing exogenous or external sources of testosterone. While this is an effective strategy, it’s not without side effects. The most serious is that your body stops producing testosterone itself, and you become entirely reliant on replacement therapy. Once you start, you’ll need to continue with this treatment indefinitely (1).

Another problem is that HRT is only available for men with very low testosterone levels – clinically low. It is not available to men whose levels are just a little on the low side of normal.

The good news is that healthy men can increase their T-levels with a supplement – testosterone boosters. Instead of replacing your hormones, these products contain ingredients designed to increase testosterone production naturally. For many men, this is a much better solution.

If you have low testosterone, or simply want to increase your levels to their natural maximum, the best testosterone boosters can help. Not sure which one to choose? Here are ten of the best, all tried, tested, and reviewed just for you!

4. Crazy Bulk – Testo Max

While low testosterone levels can affect almost all men, exercisers and bodybuilders are the most likely group to want to maximize their T-levels. Why? Because testosterone plays a vital role in building muscle and burning fat. CrazyBulk is a T-booster aimed at this particular demographic.

CrazyBulk is an effective T-booster made with natural, tested ingredients. Formulated for maximal results, this product is sold as a safe alternative to anabolic steroids. While that is a bit of a stretch, as no natural testosterone booster can match the effect of steroids, this product should produce noticeable results within two weeks for most users.


  • Proven formulation
  • Safe, tested ingredients
  • Increases strength, energy, and libido, while promoting fat burning
  • Buy two, get one free!


  • Gelatin capsules – not suitable for vegetarians or vegans

Contrary to the advertising spiel, this product is not as powerful as Sustanon, trenbolone, or any other “real” anabolic steroid. Steroids are made from synthetic testosterone; they are used in hormone replacement therapy and work in an entirely different way – exogenously. CrazyBulk helps your body produce more testosterone naturally. Because of this, it’s a safe way to increase your T-levels, without the side effects associated with steroids.

Key Information about Testosterone Boosters

Declining or lower than normal testosterone levels can be distressing and a source of unhappiness for men. Testosterone levels decline with age and are also affected by things like stress, diet, and exercise. Many men turn to testosterone boosters to help them get their testosterone levels back to normal. Others use these supplements to maximize natural testosterone production, usually for better muscle building.

There are lots of different testosterone boosters available, so it pays to know a little about these supplements so you can choose the right one for you.

How do testosterone boosters work?

Testosterone boosters work by increasing your body’s ability to produce testosterone naturally. This is in contrast to anabolic steroids and hormone replacement therapy, which provide your body with an alternative source of testosterone.

Testosterone boosters mainly affect the testes, the glands responsible for testosterone production. Most T-boosters contain amino acids, vitamins, and minerals to increase teste activity, while others use herbs and other natural compounds.

The most widely used testosterone boosting ingredients are supported by research. They have been shown to have a positive effect on testosterone levels. For maximum potency, most T-boosters contain a combination of ingredients to produce the best possible results.

Some T-boosters also lower your estrogen levels. Where testosterone is the primary male sex hormone, estrogen in the main female sex hormone. Increased levels of estrogen drive your T-levels down, and so it makes sense that lowering estrogen levels will have the reverse effect.

Testosterone boosters may also contain aromatize inhibitors. As T-levels rise, estrogen levels can rise too. Some testosterone may also be converted into estrogen. Aromatize inhibitors prevent these problems.

Getting your T-levels back to normal can have a significant impact on how you look and feel. The main effects of this type of supplements are:

  • Increased muscle mass
  • Decreased body fat
  • Increased energy
  • Enhanced strength and better athletic performance
  • Increased sex drive
  • Better mood
  • More determination

Are there side effects?

Natural testosterone boosters won’t increase your T-levels to supramaximal heights. Instead, they will help you get your levels to the high side of normal. That means you won’t experience many unwanted side effects. In contrast, anabolic steroids can increase your T-levels 20-times over, putting a massive strain on many of the organs and systems in your body.

That said, because they contain active ingredients, testosterone boosters can have the following side effects:

  • Blemishes and acne
  • Receding hairline
  • Increased aggression
  • Increased sex drive
  • Sleep apnea
  • Breast enlargement – gynecomastia

These problems are directly attributable to increased levels of testosterone. Reducing your T-booster dose or switching to a less potent formula should eliminate these side effects. Because they already have high testosterone levels, T-boosters are not recommended for teenagers.

Ways to increase your testosterone naturally

Testosterone boosters are not the only way to increase your levels of this vital hormone. There are several other things you can do to improve your testosterone levels naturally.

  • Lose weight – being overweight tends to lower T-levels
  • Be more active
  • Eat more healthy fats, such as olive oil, avocados, and coconut oil
  • Get more sleep
  • Avoid stress
  • Spend time in the sunshine
  • Eat less sugar
  • Eat more seafood – high in zinc and potassium
  • Lift heavy weights in the gym
  • Cut down on long-duration cardio
  • Have more sex/masturbate

Combined with a good testosterone booster, these strategies will help you achieve and maintain higher T-levels.

Bottom Line

Low testosterone levels can affect you mentally and physically. Men with low levels of testosterone often feel less vital, driven, confident, or happy. They also tend to have less muscle, more fat, and reduced energy levels.

In contrast, men with high levels of testosterone are usually more energetic, self-assured, and may even be more successful too. It’s no coincidence that some of the world’s most powerful, influential men have high levels of testosterone.

T-levels can fall into decline for a range of reasons, not least aging. The good news is that you don’t have to suffer the ignominy of low testosterone – you can increase your levels naturally with various lifestyle adjustments and a good testosterone booster.

If, after several months of using your chosen T-booster, you don’t notice any difference, it is worth consulting your doctor. There may be a medical reason for your lowered testosterone levels, which means you could be a candidate for hormone replacement therapy. Until then, use a good testosterone booster to increase your T-levels naturally.
