A Review of The [5] Best Testosterone Booster Supplements on The Market [2021]

A Review of The [5] Best Testosterone Booster Supplements on The Market [2021]

What really means for a man to have a low testosterone level? How important is such a fact for his routine, life, health and his mood, or even for his social / sexual life?

Low testosterone levels are like the “menopause” for women, as anyone could tell you, and is a matter concerning the older persons only. 

This is a wrong assumption. 

The male body is like a “machine” requiring care for functioning properly. This care is obtained via a healthy diet, physical exercise, quality sleep and appropriate nutritional supplements.

Today we examine the Best Testosterone Boosters on The Market including:

Male hormone testosterone reaches its high values around the age of 30 to 35 years.

The following years a gradual reduction starts, being in certain cases of a slow pace, while turning to a faster rhythm (resulting in the development of several dysfunctions even at a young age). 

Below we see some of the parameters regarded as responsible for this drop observed:

  • genes
  • heredity
  • lifestyle (diet, exercise)
  • anxiety
  • environmental factors
  • health problems (eg. diabetes)
  • sleep problems (eg. sleep apnea)
  • abuses
  • hormonal disorders
  • psychological disorders (eg. depression)
  • injuries
  • obesity

Therefore, in the case of problems concerning insufficient testosterone production, we do not only address people of 3rd age, but almost every man after his first youth.

That is why in this article we will refer to supplements supporting the male body aiming at increasing the production of testosterone. Nevertheless, careful, everything is done in a natural way only, not using any chemicals or other dangerous and banned substances.

The products mentioned and examined below, are all natural, legal and produced in FDA certified Labs.

All 5 products (TestoPrime / TestoMax / Testogen / Prime Male / TestoFuel) achieve the best sales worldwide, holding the best user reviews. All three products are naturally aiming at testosterone boosting.

A detailed presentation and discussion of these popular supplements, as well as their capabilities follows in the coming lines of the article. 

The results presented rely on the assessment of users of the specific supplements who agreed to share with us their experience and their comments (positive and negative).

What we did in this article was to collect all these experiences – as well as information about the specific products – and present them to you in an honest review of the Best Testosterone Boosters for 2021.

4th product: Prime Male – Top Natural Test Booster 

Prime Male, a red pill that can make a difference. You should not allow stress, the time passing and the heavy daily life to “steal” your masculine power.

Low testosterone levels can have significant effects (negative effects) on your daily life as:

  • reduced athletic ability
  • reduced sexual ability
  • reproduction problems
  • hormonal problems
  • psychological problems
  • reduced self-esteem & difficulty in socializing
  • reduced body (muscle) mass

The above are just some of the serious effects of low testosterone on a man’s life. The most important decision is to accept that your organism is starting a reverse course and needs as much reinforcement as possible.

Not to mention the false information presented by many companies about the various supplements, a fact placing your life and health at risk.

Frequently Asked Questions – Everything you should know

Q: What “low testosterone” means? Is it a condition?

A:  It could be a condition (in rare cases), but it is also a normal process of male organism aging. Growing up involves a gradual decline of this important hormone, meaning several more changes in their body, mind & function.

Brain function, sexual function, look, and mood, are conditions interrelated with this so important hormone, the declining production of which inevitably affects them in a negative way.

Q: What are the normal testosterone levels in adult men?

A: Could be an easy answer by giving a number. Testosterone levels depend on many other factors. Clearly gender plays a decisive role, but also age, health status, heredity, external environment, are some of the factors that affect the levels of testosterone produced.

However, – in general – the following ranges considered as normal according to Healthline:

  • infant age 0 months – 5 months: 75 – 400 ng / dl
  • infant & childhood 6 months – 9 years: <7-20 ng / dl
  • childhood 10 years – 11 years: <7 - 130 ng / dl
  • adolescence 12 years – 13 years: <7 - 800 ng / dl
  • adolescence 14 years: <7 - 1200 ng / dl
  • adolescence 15 years – 16 years: 100 – 1200 ng / dl
  • adulthood 17 years – 18 years: 500 – 1200 ng / dl
  • adulthood 19 years and over: 240 – 950 ng / dl

Q: What is the role of testosterone in the male organism?

A: Testosterone is the main male hormone (existing in lower numbers in the female organism) and is primarily responsible for the so-called “male sexuality”, as well as for the general masculinity of a man (male characteristics). Following the age of 30, the natural production of testosterone gradually decreases, until you reach about the 80 years of age, where it’s nearly half.

Nevertheless,  low testosterone levels are associated with many side effects, as:

  • depression
  • decreased sexual desire
  • decreased sexual ability (erectile dysfunction)
  • mental illness
  • unnecessary fatigue / low energy levels
  • loss of muscle mass (muscle atrophy)
  • sleep disorders (mainly insomnia)
  • poor sperm quality / reproductive problems
  • reduced function of the nervous system
  • reduced cognitive function

Q: Why athletes prefer testosterone booster supplements?

A: The sports community in general is very familiar with this kind of supplement, making a perfect sense. The composition of these supplements enhances muscle mass and increases physical strength and energy in a very short time.

Besides, the athlete experiences higher energy and endurance during physical exercise, feeling less physical strain.

In fact, natural testosterone boosters (as the 5 products mentioned above) do not cause any toxicity to the liver and kidneys, are not addictive and do not cause any side effects or health problems / complications.

Q: Do best testosterone boosting supplements work?

A: Yes. As long as the right product is found. They can even increase your testosterone production by 20 to 50%  but only for as long as you take them. After discontinuing the supplement, testosterone levels will gradually return to previous levels (i.e. before the administration of the supplement).

Q: When (and in which cases) is it recommended to take them?

A: There are different cases. In cases of no serious condition (requiring medical monitoring & prescribing medicines), you can take a natural testosterone booster in the following cases and for the following reasons:

  • you are over 30 years old (your testosterone has started to decline anyway)
  • you are an athlete (you need extra support)
  • you have sexual dysfunctions (perhaps due to commitments of everyday life & increased stress and therefore you need strengthening of your organism)
  • you have difficulties with the brain cognitive function (problematic memory, reduced perceptual ability, difficulty concentrating)
  • you have had sleep disorders (especially if you are in the third age)
  • you have frequent muscle, bone or ligament injuries (and therefore need strengthening of your muscular / skeletal system)

** It is always a good idea to consult your doctor before using any dietary supplements

Q: Can a Testosterone Booster Increase Penis Size?

A: Basically where it helps – among other things –  is to enhance your muscle gains and increase your muscle mass, to ensure better sexual performance.

You will also get better cardiovascular function, better muscle oxygenation and clearly better blood circulation to the genitals.

This will definitely result in a better quality erection and possibly improve its size as well.

Q: Can masturbation affect testosterone levels in a negative way?

A: This has not been scientifically proven yet. In particular, scientists have not identified any long-term effects of masturbation on testosterone levels (although it may affect it for a short time).

Q: What Are The Best Testosterone Booster Supplements?

A: For the past year but also for the year coming, according to valid reviews, the best supplements are:

  • TestoPrime – ( Read a Detailed Review From Medical Daily here)
  • TestoMax
  • Testogen 
  • Prime Male
  • TestoFuel

The reasons for this selection have been explained in detail.  

Q: Are suitable for use by minors?

A: Though these are completely natural dietary supplements (with very careful composition of the highest quality), their use by minors is not recommended.

Unless recommended by a doctor, it is advisable to avoid giving them to children and adolescents.

Q: Can participate in a stack?

A: Yes. You can take testosterone boosters at the same time with other supplements to increase muscle mass, athletic performance or even with fat burners for a complete training cycle.

Q: Are Testosterone  Boosters detectable in anti-doping tests?

A: No. Their natural composition includes no forbidden or questionable ingredients and for this reason, they are normally administered even to professional athletes.

Q: In which countries are they shipped?

A: That depends on the company. However, in most countries of the world the shipment is carried out normally. Each company usually lists the countries in which it does not deliver products.

Q: Is delivery also made via ARO (Army Post Office)?

A: Usually yes. Most companies deliver normally to APO without any problems.

Q: Can I request a “discreet” delivery of the products so no one knows what I ordered?

A: No need. In any case, the delivery takes place in a discreet package protecting your privacy.

Q: Which payment methods are available?

A: Again, this depends on the company. In most cases, payment can clearly be made by debit or credit card (American Express not accepted by all companies), while some companies accept PayPal, AmazonPay or even bank deposit.

Q:  Are these transactions secure?

A:  Yes. No question about this when it comes to such big companies. This is another reason why we do not recommend buying products from dubious companies.

Q: How fast will I see results?

A: From the very first time you use the supplement, you will see significant changes in your energy and endurance. However, the physical benefits will take a little longer to reach a satisfactory level. Most users state that after about 3 weeks of use they started to see a clear change / improvement.

Q: Are these products FDA Approved

A: No. FDA does not approve Dietary Supplements (Natural Supplements). Only Medicines.
