What Are Testosterone Supplements?

Testosterone Supplements, also commonly referred to as testosterone boosters, or test boosters, are a class of supplements which work to raise T-levels by releasing testosterone that has already been produced by the body but has otherwise been made inactive.
This neutralization of naturally-occurring testosterone is a primary reason for low-T.

Low levels of testosterone can be brought about by things like an increase in SHBG (sex hormone-binding globulin), or abnormally high levels of estrogen.

Key ingredients used in Prime Male include:

• D-Aspartic Acid Calcium Chelate: Amino acid that aids testosterone synthesis and release
• Black pepper extract: Increases absorption and bioavailability of other nutrients
• Boron: Mineral that reduces sex hormone binding globulin to increase free testosterone
• Korean Red Ginseng: Herb that enhances libido and sexual performance
• Luteolin: Antioxidant that inhibits estrogen production
• Magnesium: Mineral vital for testosterone production
• Vitamin D3: Vitamin that helps regulate testosterone synthesis
• Vitamin K2: Helps D3 absorption and prevent testosterone breakdown
• Vitamin B6: Essential for androgen (testosterone) synthesis
• Zinc: Mineral that stimulates testosterone production while inhibiting aromatization

Bottom Line

With science-backed ingredients known to boost testosterone, Prime Male aims to help men restore their vitality. Most users report seeing benefits from increased energy and libido to muscle gain in a matter of weeks.

How TestoFuel Works

The ingredients in TestoFuel have been specially selected for their ability to encourage the body to produce more endogenous testosterone. Compounds like D-Aspartic Acid, Vitamin D, and Ginseng provide the building blocks and signals for boosted testosterone synthesis.

Higher circulating testosterone promotes increased protein synthesis and muscle repair. TestoFuel enhances the body’s natural processes for elevated testosterone with no harmful side effects.

Ingredients Commonly Used in Testosterone Supplements

Some common ingredients that are found in testosterone supplements (either individually or in some combination) include:

The best testosterone supplements will usually contain a proprietary blend of one or more of these ingredients, among others. By using a combination of multiple ingredients, a more potent and effective product is produced.

Due to the increased knowledge of these natural testosterone-releasing substances, and because of the illegal status of anabolic steroids and prohormones, the supplement industry is now flooded with testosterone boosters. Obviously, this makes choosing the right one a challenging task.

Benefits Of Using Testosterone Boosters

Typical benefits that users can experience when taking a testosterone-boosting supplement may include:

Reasons for Taking Testosterone Boosters

Why take a testosterone supplement? There are several reasons why you might consider using test boosters, from boosting your sex drive to improving your gains at the gym.

Here are a few of the main reasons why men use these types of supplements:

Andropause

At around the age of 40, testosterone production in men typically starts to dwindle by about 1% per year. These lowered levels may not even be noticed until a man reaches his 60’s.

And half of all men will suffer from low test levels by the time they’re in their 80’s. As a matter of fact, men in their 80’s often have testosterone levels that are over FIVE TIMES LOWER than that of men in their 20’s.

Symptoms of andropause include decreased muscle mass and stamina, lowered sex drive, erectile dysfunction, fatigue, poor memory and cognitive function, depression and/or lack of motivation, difficulty sleeping, and weight gain, among others. Taking a good testosterone supplement can often help to reduce or eliminate symptoms related to andropause.

Bodybuilding

It’s no secret that bodybuilding and testosterone go together like chocolate and peanut butter. Testosterone naturally increases muscle growth, lowers body fat, speeds recovery, boosts strength and enhances athletic performance.

For these reasons, anabolic steroid use is notoriously prevalent in the bodybuilding community, despite the inherent risks involved. A far safer alternative to steroid use is natural testosterone boosters, which work to increase your body’s own production of testosterone, rather than injecting it.

Mental Function

Having reduced testosterone levels can affect a lot more than just physical performance. Mental fog, poor memory, and difficulty in problem-solving are some of the negative impacts to cognitive function due to low T-levels.

Taking testosterone supplements can dramatically improve brain function for those suffering with low test levels, making it one of the best nootropics available for many men.

Psychological Well-Being

It’s not just mental performance that can lag as a result of low-T, but emotional health as well. Loss of motivation, diminished confidence, and depression are some of the negative psychological repercussions associated with low levels of testosterone.

As testosterone levels are increased, so is the feeling of well-being and other positive emotional states related to healthy T-levels. Unfortunately, many men mistakenly turn to anti-depressant drugs to treat their symptoms, unaware that an all-natural testosterone booster would be far safer, and more effective.

Sexual Performance

Without a doubt, erectile dysfunction is one of the most common and well-known symptoms of low testosterone production. Symptoms of testosterone-related sexual performance issues include the inability to maintain (or even achieve) an erection, diminished sex drive, and poor erection quality.

Many guys will agree: if your test levels aren’t where they should be, taking a high-quality testosterone supplement can make some serious improvements to your bedroom performance.

Weight Loss

Remember when you were in your teens and it seemed like you could eat anything you wanted and never gain weight? Part of the reason has to do with high testosterone levels.

Testosterone is directly related to the regulation of metabolism – the less testosterone you produce, the slower your metabolism, and the more weight you gain. Therefore, if you want to keep your metabolism revved up and help to keep off that extra weight, try taking a testosterone booster and see what happens.

Common Testosterone Supplement Questions

Here are just a few of the questions we are commonly asked about:

1. Are Testosterone Boosters Steroids?

No, they’re not. In fact, these supplements are typically made of 100% natural ingredients, such as D-aspartic acid, ginseng, vitamin D (or D3) zinc, boron, and tribulus terrestris, among others.

These hormone boosting ingredients encourage the body to produce more of it’s own testosterone, naturally.

2. Are Testosterone Supplements Legal?

Yes. These types of supplements are generally made with herbal extracts, amino acids, vitamins, and/or other naturally-occuring ingredients.

Unlike synthetic anabolic steroids, testosterone supplements allow you to increase your body’s own production of testosterone naturally, in a 100% healthy and legal way.

3. Are Testosterone Boosters Safe?

The testosterone supplements that we recommend are absolutely safe. We only endorse those supplements made with the best, highest-quality, 100% natural ingredients, and which are produced in certified facilities.

All ingredients used will be shown to be safe and effective in otherwise healthy adults. With that in mind, you should always speak to your doctor before trying any new supplement if you’re currently taking medication or have other health concerns.

4. Do Testosterone Supplements Cause Side-Effects?

Rarely, if ever. Since the ingredients are naturally-occurring, most over-the-counter testosterone boosters will not cause any known side-effects.

5. Will Testosterone Boosters Show Up On A Drug Test?

Generally, no. Testosterone supplements are typically made up of an entirely natural ingredient profile (rather than a chemical formula), and will not normally cause a false positive on a drug test.

However, some supplements may contain a chemical formula and/or certain ingredients which may not be 100% natural, or for whatever reason could potentially trigger a false positive.

If we recommend any supplement where this might be a concern, we will clearly display a warning that the product may contain ingredients that could potentially cause complications with a drug test.
