12 Best Supplements to Boost Testosterone Levels in 2021

Best Supplements to Boost Testosterone Levels WLFH featured image

Testosterone is a crucial hormone for men. It has many important functions, including muscle building, fat burning, sexual potency, mood, and cardiovascular health.

Unfortunately, testosterone levels tend to decline with age, and most men’s levels peak during their mid-30s (1). Some men’s T-levels fall so far that they are said to be in andropause – the male equivalent of the female menopause.

The good news is that you don’t have to suffer the ignominy of low testosterone. You can use a test booster to increase your levels naturally. But which are the best testosterone boosters, and how do they work?

Some men are prescribed testosterone replacement, which means using exogenous testosterone. These drugs are usually delivered in the form of regular injections. Testosterone replacement therapy (TRT) is effective, but it’s also expensive and requires frequent doctor’s office visits. There are also concerns over the long-term risks.

Natural testosterone boosters work by stimulating your body to start producing more testosterone. Because they are made from natural ingredients, many of which are herbs and other traditional remedies, testosterone boosting supplements are much safer.

Not sure which product is right for you? Whether you are looking for the best testosterone booster for men over 50 or the best testosterone booster for muscle gain, in these test boost reviews, we reveal the 12 best products for men with low testosterone who don’t want to use TRT.

12. Modern Man V3

Key Information

Considering the following crucial information before buying or using a testosterone booster.

Do testosterone boosters work?

Yes, they do, but their effect can vary from one man to the next. If you are young and your levels are just slightly below average, you might not notice much of a benefit to using a T-booster. After all, your levels are already close to optimal.

But, if you are an older man in the throes of andropause, a good test booster will have a much bigger impact on how you look and feel.

So yes, testosterone boosters do work, but how big an impact they’ll have depends on your personal circumstances.

Dosage Guides

To get the most from any testosterone booster, you should follow the manufacturer’s guidelines and only take the recommended amount. Strong man in the gymThis could be one capsule per day or several. It all depends on the formulation of the product.

However, while it may be tempting to take more than the recommended amount, this is not a good idea. Use your chosen product according to the guidelines to get the best results with the fewest number of risks and side effects.

Benefits of Testosterone

There are lots of benefits to getting your testosterone levels back to normal. The main benefits are:

  • Increased muscle mass
  • Increased bone mass
  • Decreased fat mass
  • Increased strength and power
  • Increased endurance
  • Increased energy
  • More positive mood
  • Increased motivation, drive, and willpower
  • Increased libido
  • Increased sexual stamina
  • Healthier sperm

Low levels of testosterone will have the exact opposite effect.

Side effects of taking testosterone boosters

Increasing your testosterone levels should have mainly positive side effects. However, some men may also experience the following:

  • Greasy skin
  • Acne
  • Increased aggression
  • Increased sweating
  • Restlessness
  • Spontaneous erections
  • More vivid dreams

If you experience any of the above, cut back on your testosterone booster dosage as your T-levels may be getting a little too high.

Bottom Line

Low testosterone can make life pretty miserable. It can lead to muscle and strength loss, fat gain, and low libido. It can also cause insomnia, lost willpower and motivation, and even increase your risk of depression. Low testosterone sucks!

However, you don’t need to accept low testosterone as normal. Using a quality testosterone booster can help get your levels back to where there should be.

For many men, a quality testosterone booster is preferable to testosterone replacement therapy. Testosterone boosters are more accessible, don’t require a prescription, and you won’t need to go to a doctor’s office every few weeks for an injection.

In contrast, testosterone boosters are cheap, readily available, more convenient, and don’t require injections.

If you have any of the symptoms of low testosterone, you don’t have to suffer them in silence. Instead, set yourself up with a good testosterone booster, and wave the low-T blues goodbye!
