Test-FX: Why we believe it will benefit your Testosterone

Test-FX testo booster is a potent supplement for men designed to support a naturally healthy testosterone level.

If you suffer from poor energy levels, have a low libido, struggle with muscle gain, or are over the age of 35, then Test-FX is for you.

This is because Test-FX contains a comprehensive stack of scientifically-backed ingredients that work synergistically within the body's own HPTA axis.

Our formula includes a selection of essential minerals that are rate-limiting factors in the maintenance and production of testosterone.

A blend of important vitamins that act to facilitate the bio-synthesis of testosterone in the testes.

A mixture of bioactive botanicals that help inhibit the conversion of testosterone to oestrogen's, which when elevated can contribute to body fat accumulation and excess water retention.

With that said, we won't fill you with false promises of boosting your testosterone levels by 4769.12% in 7 days. Nor do we make any other unfounded statements that tout Test-FX as some magical pill with the power to metamorphose you into the incredible hulk.

That is simply because, It won't.

What Test-FX will do is give you a legitimate edge in optimising your testosterone levels naturally.

Bottom line is testosterone boosts physical performance

The male androgenic sex hormone Testosterone is proven by science to increase strength, muscle mass, speed, performance and is paramount to excel in any type of physical performance; it is of no wonder why synthetic testosterone is banned by all drug tested sports.

Testosterone is also a libido booster; typically men with higher T levels have a higher libido and vice versa. Furthermore science has discovered that as men age their testosterone production declines. While the exact mechanism of this is not yet known, it is known that maintaining a healthy testosterone level plays a significant role in anti ageing.

Helping natural testosterone

All of the above is just part of the story; Test-FX does not interfere with or break any endogenous endocrine functions. why does this matter? Simply put - using synthetic prohormone supplements turns off internal testosterone production.

This will go unnoticed for the duration these supplements are used simply because they are just replacing what has been shutdown. However once supplementation is stopped, sadly the user may well suffer from suppressed testosterone production (since the replacement hormone has finished), and typically lose everything that was gained.

but that's not all....

Using a synthetic prohormone type supplement can actually cause an increase in the female hormone estrogen. What's more, an increase in estrogen can actually increase body fat and water retention; giving you that bloated puffy look that you always wanted to avoid.

Results from Test-FX aren't temporary

There are no bad side effects such as low testosterone when supplementation of Test-FX is stopped; typically users keep the fruits of their hard labour. No problem! The only down side is that they won't continue to improve as rapidly as they did while using Test-FX.

On the comeback trail

I have used these before and was always really happy with the results but since lockdown happened I confess to doing nothing but sitting on my backside. My energy and motivation levels were rock bottom, but at nearly 53 it was either, get on with it or vegitate. Muscle memory and Test-FX in equal measures and a few weeks on and I'm buzzing, really motivated, focused and back at it. And it's not just in the gym where I'm feeling the benefits 😉

Definately boosts testosterone

I recently received an email from dna lean requesting my feedback, so here it is: I'm an athlete and as part of my training, at least once per year I get a blood test done to check up on my health. Over the last 24 months or so I'd noticed that my testosterone level had started to decline, not only did I notice a drop in my energy levels, but my recovery wasn't quite optimal. Unfortunately my blood tests also confirmed the same; testosterone was low. Since taking Test-fx I feel fantastic, both my energy and recovery is back to what it was 2 years ago. My most recent blood test has also come back good showing that my testosterone has been boosted and is in the high range. Test-fx is an Absolute rock solid supplement!

The best I have used

Before taking Test-FX I was suffering from poor sleep, low-libido, and my weights sessions had seemingly become a little lacklustre. What I found appealing about this product was that the description wasn’t filled with the usual marketing nonsense, rather, it was refreshingly honest. So anyway, despite being sceptical, I decided to buy. I am now on my 3rd tub, honestly this is the best supplement I have used! After 3 weeks my libido started to normalise again, I was sleeping a solid 7 hours, and I felt alive and kicking! Right now my bench press is also up by 9 kilos and I could not ask for more. I highly recommend test fx.

Zinc

The mineral Zinc is essential for all cellular growth and also is a vital constituent of numerous enzymes present in every animal on earth. The human body only holds a small pool of Zinc which is rapidly used and therefore needs replenishing on a daily basis. If you are not eating enough Zinc your body will quickly recognise the deficit and instantly conserve its supply by retarding muscle growth, reducing immune system activity, and also sexual function. It should also be noted that zinc helps maintain a healthy Testosterone level in men, fall deficient in this essential mineral and you may find that your Testosterone levels also suffer.

Magnesium

High levels of Magnesium are contained in our bones, in fact approximately 60% of the human body's Magnesium content is found in our bones. If you are into working out, you want strong bones, strong bones need Magnesium! The other 40% of your Magnesium is used for, and essential for all cellular manufacturing processes, the burning of glycogen for energy, transmitting genetic codes to assimilate new proteins, and is also essential for the activity of over 300 enzymes.

Vitamin B6 (Pyridoxine)

Vitamin B6 is what we call a coenzyme (enhances the action of another enzyme) for over 100 enzyme functions in the human body. The most relevant functions in this instance being the metabolism of amino acids and is therefore critical to optimum growth and repair of skeletal muscle tissue.

Tribulus Terrestris

Tribulus Terrestris is a flowering plant that has a natural affinity for warmer climates and hence is found mainly in Africa, Australia, and warmer regions of Europe.Tribulus Terrestris is purported for its natural Testosterone boosting properties and as such, Amazonian tribes have taken advantage of this natural wonder herb for centuries, using it in teas and other preparations for its virility effects and to increase testosterone.

D-Aspartic Acid

D-Aspartic Acid otherwise known as DAA, is an amino acid which some studies indicate has some very special properties. An Italian study in particular showed some very promising results. When DAA supplements were given to a group of healthy male weight trainers for 12 days. After which 87 percent of the subjects had significantly increased their Luteinizing hormone and Testosterone levels by 33 and 42 percent, respectively.

Boron

Numerous studies have found that Boron is probably essential for normal production of steroid hormones in humans, especially hormones involved in muscle growth. It's yet to be established how much Boron we need, however new properties and functions of Boron are being discovered all the time. It is now known that Boron plays a key role in optimisation of natural production of androgens and may even increase testosterone levels.

Reservatrol (Polygonum Cuspidatum)

Resveratrol is a phytonutrient (plant based nutrient) which can be found in berries such as raspberries and blueberries and also in the skin of red grapes. Most supplemental forms of Resveratrol are extracted from the Chinese knotweed plant; Polygonum Cuspidatum. Resveratrol has been found to have some amazing properties which may have various positive health benefits such as but not limited to; antioxidant properties, cholesterol lowering, cardiovascular function, reducing inflammation and supporting hormonal production. According to some studies, Resveratrol also significantly increases natural testosterone production from being both a selective Oestrogen receptor modulator[67] and an Aromatase inhibitor.

Red Wine Extract (Vitis Vinifera)

Red wine extract is also a phytonutrient similar to Resveratrol, extracted from red grapes. Red wine extract like Resveratrol, has a wealth of positive health benefits and has been linked to promotion of Testosterone production. These two compounds work in synergy; further enhancing the absorption and effectiveness of each other and therefore increasing their potencies when combined.

Vitamin D3 (Cholecalciferol)

Vitamin D3 is one of a collection of vitamins that are essential for human function. Vitamin D3 is known to help regulate over one thousand biochemical and enzymatic reactions and functions. The most commonly known functions being the facilitation and regulation of the absorbtion of the minerals calcium & phosphorus needed for healthy mineralisation of bone. However vitamin D3 is much more than just a vitamin, it's actually a steroid hormone. In fact, one study in particular, showed that the effect of vitamin D supplementation on testosterone levels in men lead to a significant increase in testosterone. Although good amounts of naturally occurring vitamin D3 are found in eggs, fish and seeds, Test-FX is "mega" dosed with D3 to ensure maximum testosterone output.

Stinging Nettles (Urtica Dioica)

Stinging nettles are one of the plants you may want to avoid touching, however ingestion of this powerful plant can have some great health benefits. Stinging nettles do not actually act as a Testosterone booster; rather they play their part in the Test-FX formula by helping to keep your Oestrogen levels in check. Extracts of Stinging nettles contain compounds that have been shown to inhibit the Aromatase enzyme which is responsible for converting increased levels of Testosterone to the female hormone Oestrogen. Stinging nettles have also been shown to have a mild anti inflammatory effect and may even aid in the relief of Benign Prostatic Hyperplasia (BPH).

White Button Mushrooms (Agaricus Bisporus)

The White button mushroom is one of the most commonly eaten mushrooms in the world today. This mushroom is grown globally, cultivated in more than seventy countries. Commonly referred to as white button mushroom, button mushroom, table mushroom and cultivated mushroom. This mushroom has some great nutritionals, packed full of highly bio available B vitamins amongst other healthy micronutrients. Extracts of these powerful mushrooms have been shown to contain Aromatase Inhibitors (AI). Aromatase is an enzyme which is responsible for synthesising female sex hormones - Oestrogens. In some cases of men with naturally high Testosterone Levels the Aromatase enzyme can convert some Testosterones to Oestrogens, causing undesirable effects such as increased body fat, water retention and Gynocomastia. Aromotase inhibitors work by "blocking" the Aromotase enzyme so that Testosterones cannot be converted to Oestrogens, thus maintaining a higher Testosterone level and preventing unwanted side effects from increased Oestrogen levels.

What is testosterone?

Testosterone is a male anabolic and androgenic steroid hormone produced in the testes. Testosterone is metabolised and manufactured from Cholesterol; endogenous Testosterone levels are maintained via an internal biochemical feedback mechanism known as the Hypothalamus, pituitary, Testicular Axis (HPTA).

Testosterone is an androgen and as such gives rise to male characteristics; facial and body hair, deepening of the voice, virility, increased strength and muscle mass and boosted libido, Testosterone also plays an integral role in male fertility and the production of sperm. Men naturally produce Testosterone in much larger quantities than women, typically Testosterone levels significantly increase when a young male reaches puberty, but, also steadily decline from around the age of 30 onwards as part of the ageing process.

What are testosterone boosters?

A Testosterone booster is a class of supplement that is designed to aid in the natural production of Testosterone and maximise its output. These supplements do not replace, nor suppress endogenous Testosterone; rather they help to support and optimise the natural production of testosterone. They can contain a variety of different ingredients from minerals, to herbs and other plant extracts. Testosterone boosters are very much different from supplements known as prohormones, prohormones can suppress natural Testosterone production. Users of prohormones typically find they need to run Post Cycle Therapy (PCT) to try and recover their own production of Testosterone after they have stopped using prohormones.

Who can use Test-FX™?

Test-FX™ is not intended to be used by anyone under the age of 18. If you are a male over the age of 18 and in good health, you can safely take these pills. Test-FX™ is designed to support Testosterone production and is therefore beneficial to anyone who works out in any physical capacity whether it is competitive or just for fun. Since Testosterone levels typically decline with age, it may be of particular use for anyone who is over the age of 30.

Does Test-FX™ have any ill side effects?

Test-FX™ is a food supplement and does not have any known side effects, therefore you should not find that you experience any negative or ill effects with this product, however we always recommend that you check with your doctor before you start using any supplements, especially if you are taking any prescription medicines, over the counter drugs, or have any health related problems.

Is Test-FX™ the best UK testosterone booster?

This is one of our most frequently asked questions and in our opinion one that is impossible to answer. There is no absolute measure of what the best testosterone booster is, and as such is not tangible. Besides that we don’t focus on other companies products, we innovate, and focus on creating the best possible products that we can bring to market. We would question the integrity of any company that does claim to have the "best" product on the market. Try our products for yourself, you can be the judge and leave a product review.

Are testosterone boosters bad for you?

No. Testosterone is naturally produced in the testes and is necessary for maintaining health, athletic performance, recovery and libido.

Do testosterone boosters really work?

Testosterone boosters can contain a myriad of ingredients, needless to say some are effective and some are not so effective. All of the ingredients contained within Test-FX™ are thoroughly researched and backed-by-science.
