Vitamin D 12.5µg

Vitamin D is a fat-soluble nutrient and steroid hormone, which regulates more than 1,000 bodily functions.

The benefits of Vitamin D on testosterone production are
well evidenced.

Studies have shown that men with sufficient vitamin D levels have
significantly higher testosterone than those with low levels.

Studies have also shown that supplementing with Vitamin D can increase free and total testosterone up to 25%.

Vitamin D has been clinically proven to:

  • Contributes to the normal function of the immune system.
  • Contributes to the maintenance of normal bones.
  • Helps maintain normal muscle function.

Bone loss, low testosterone, compromised immunity and reduction of sperm quality are
just a few results of vitamin D deficiency.

It's estimated that around 80% of the UK population have sub optimal
levels of Vitamin D.



Vitamin C 80mg

Vitamin C (ascorbic acid), a powerful antioxidant and water-soluble vitamin.

This means that it dissolves in water and is delivered to the body’s tissues but is not well stored, so it must be taken daily through food or supplements It helps the body’s detoxification pathway.

It enhances liver function by promoting the production of detoxifying enzymes.

These enzymes assist in breaking down toxins and facilitating their elimination from the body including removing excess oestrogen.

It also plays a proven role in:

  • Our endocrine health which controls hormone production, requires vital levels of this nutrient.
  • Managing cortisol levels – Vitamin C is rapidly depleted during stress.
  • Elevated cortisol levels inhibit testosterone production – thereby keeping levels optimal reduce this risk.
  • Helps optimal functioning of the nervous and immune systems.
  • Function of the immune system
  • Protects DNA, proteins, and lipids from oxidative damage – vital in super-aging.

B-Complex 100% Daily Reference Intake of all B-Vitamins

Our formulas are the only men’s hormonal health supplements that include all the B Vitamins.

The B-complex vitamins have dramatic mood-elevating effects — more so than almost any other nutrient.

The family helps the body and mind stay healthy, sharp, energetic, balanced, and they play a crucial role in the detoxification process.

The master controller of hormones - the endocrine system - needs the B
vitamins to assist in the production and metabolism of hormones and neurotransmitters.

These water-soluble nutrients cannot be stored by the body – needing daily intake.

Each plays an essential role and are co-factors for many other nutrients. Deficiency in one can impact the way the other’s work, which is why there are major benefits from including them together.


Thiamine (B1) 1.1mg

Thiamine plays a vital role in metabolism, helping the body break down and release energy from food. Thiamine also helps to metabolise glucose.

It’s also important in maintaining the health of the nervous system.

When you're deficient in vitamin B1, you might experience symptoms such as fatigue, muscle cramps, various pains, and a reduced tolerance to pain. Carbohydrate addiction can be a sign of being thiamine deficient.


Riboflavin (B2 ) 1.4mg

Every single cell within your body requires vitamin Riboflavin and other B vitamins cannot perform their roles unless an ample amount of B2 is in the body.

Riboflavin is one of the essential nutrients needed in testosterone production.

One of the most crucial roles is its ability to inhibit testosterone 5 alpha-reductase.

This enzyme:

  • Converts testosterone into DHT in the testicles and prostate.
  • DHT is crucial for some functions in the male body.
    But needs regulation.
  • Too much of it can lead to hair loss and other unwelcome health issues.

Niacin (B3) 16mg NE

B3 is a natural human growth hormone booster that can lead to anabolic changes in building lean muscle mass and strength.
It helps regulate cholesterol levels, both good and bad, which indirectly improves testosterone levels.

Research has found that supplementation daily can:

  • boost testosterone levels.
  • reduce erectile dysfunction.
  • lower lipid and cholesterol levels.

Leydig cells, cells in the testicles, take cholesterol and convert it to testosterone, making vitamin B3 a must have ingredient in our formulas.


Pyridoxine (B6) 1.4mg

B6 is clinically evidenced to regulates sex hormones. We can’t produce it ourselves, so it is essential we get this from other sources. The older we get the more B6 we require, making deficiency more likely.

It directly influences testosterone production by increased demand for androgens. When the body lacks B6, the brain increases oestrogen levels. This vitamin acts as a counterbalance for hormone regulation.

B6 also:

  • Plays a major role in processing the protein, carbs, and fats you eat.
  • It is involved in the autonomic processes of your nervous and immune systems.
  • Helps with memory, cognitive functions, and energy levels,

Folate (B9) 200µg

Vitamin B9 is more commonly known by its synthetic supplemental form 'folic acid'.
It is crucial for proper brain function and plays an important role in mental and emotional health.

Folate is involved in:

  • The synthesis of neurotransmitters like serotonin, dopamine, and noradrenaline.
  • These neurotransmitters play a role in mood regulation and overall mental well-being.
  • Works with vitamins B6 and B12 and other nutrients to control blood levels of the amino acid homocysteine.

It is common to have low levels of folic acid.

Chronically low folate levels can lead to mood disturbances, which may indirectly contribute to feelings of tiredness and fatigue.

Alcoholism, inflammatory bowel disease (IBD), and celiac disease can cause folic acid deficiency. Also, certain medications may lower levels of folic acid in the body.


Cobalamin (B12) 2.5µg

Helps reduce tiredness and fatigue.

Vitamin B12 is a vital member of the B vitamin family, playing a pivotal role in various bodily functions, notably the formation of red blood cells. When there's a chronic shortage of vitamin B12 it can diminish the blood's ability to carry oxygen, leading to feelings of weariness and fatigue.


Biotin (B7) 50µg

Biotin, plays a crucial role in our body and directly impacts our hormones:

It aids in proper endocrine function. A deficiency of biotin can lead to dysfunction in both the adrenal glands and the thyroid,It’s also required for healthy hair, skin and nails.


Pantothenic Acid (B5) 6mg

Pantothenic acid provides foundational support for both Phase I and Phase II detoxification. Vital for elimination of excess oestrogen and environmental toxins.

It is essential for testosterone production as the testes require B5 vitamin to help convert cholesterol to testosterone.

In addition:

  • It plays an important role in the production of adrenal hormones.
  • All the steroid hormones will be produced only with ample B5 in the system.
  • It is involved in the production of neurotransmitters.
  • Pantothenic acid is a stamina enhancer and prevents certain types of anaemia.

Deficiency can cause fatigue, headaches, nausea and tingling in the hands.


Magnesium 150mg

Magnesium is one of the most important minerals needed for life - involved in over 300 enzymatic processes in the body.

It has essential benefits on men’s hormonal health:

  • It assists with managing SHBG molecules which bind the majority of testosterone in your body and make it inactive.
  • It’s essential for the metabolism of nitric oxide, which is involved in the erection process.
  • It boosts sleep quality which is vital for testosterone health as testosterone is replenished overnight – requiring good quantity and quality sleep.
  • It promotes recovery from intense workouts, improves muscle health and lean body mass.

    Additional, clinically proven benefits include:

  • Magnesium contributes to a reduction of tiredness and fatigue.
  • Magnesium contributes to electrolyte balance.
  • Magnesium contributes to normal functioning of the nervous system.

    Studies have shown that 50% of the population do not meet their daily requirement.

Zinc 14mg

Important mineral that is crucial for male hormonal health.

It plays a key role in supporting the endocrine system and plays
a major role in testosterone production. 

Optimal zinc levels prompt Luteinizing hormone, which stimulates production of
testosterone in men.

Low levels are intrinsically linked to low testosterone levels and poor fertility.

Zinc has been clinically proven to:

  • Support normal testosterone levels.
  • Reduce tiredness and fatigue.
  • Supports skin, hair and nails health.

Zinc deficiency affects over two billion people worldwide and ranks as the 11th major risk
around the globe in malnutrition.



L'Citrulline 500mg

L'Citrulline is another powerful amino acid that works in partnership with L-Arginine which is
why we included both in this formula.

It is regarded as a pro-erectile agent because it is a precursor of L arginine, which produces nitric oxide. In turn, nitric oxide uses the same pathway as Viagra.

Supplementation has been proven to increase blood flow without increasing blood pressure.

Additionally, it benefits cardiovascular health:

  • Vasodilation - enabling blood vessels to expand.
  • Increases blood flow and increases oxygenation.
  • Reduces arterial stiffness.

All incredible benefits to supporting powerful pro aging and longevity
in men.


L'Arginine 500mg

L-Arginine is an amino acid, that can help with erectile dysfunction
which can be a symptom of low testosterone.

It does this by boosting nitric oxide which helps blood flow.

Due to this action, it has many other health benefits including:

  • Help to lower blood pressure.
  • Assists wound repair.
  • Support blood flow to your muscles by improve anaerobic
  • It stimulates growth hormone.
  • Boosts
    metabolism and decreases fat.

Grey Fox strategically uses the combination of L'Arginine and L'Citrulline as these two powerful amino acids work synergistically together to deliver the maximum benefits of nitric oxide


Nettle Root Extract 160mg

Nettle is beneficial for male hormones. It works primarily to keep testosterone active in the body for longer.

As most of the testosterone in your body is bound - in particularly to SHBG (sex hormone binding globulin) molecules – it renders the male sex hormone biologically inactive.

Nettle root has been shown to be effective in men’s hormonal healthy by:

  • Binding with SHBG, making more biologically active testosterone freely available to your system.
  • Blocking the enzyme that makes DHT (dihydrotestosterone) that contributes to male pattern baldness.

Ashwagandha 150mg

Scientifically known as Withania somnifera, Ashwagandha is a popular herb with many benefits and is particularly renowned for reducing stress and is classified as an adaptogen.

It helps maintain stamina, feelings or energy and vitality and promote physical
& mental wellbeing.

In terms of testosterone and hormonal balance, Ashwagandha has shown promise in supporting testosterone levels.

Studies have shown that supplementing over 16 weeks can help men with:

  • Increased Testosterone Production
  • Increased DHEA(Master Hormone) production
  • Increase the production of LH (Luteinizing Hormone) which triggers the production of testosterone

Reducing cortisol (stress hormone) also helps promote hormonal balance. It also has powerful relaxation properties and can help as a sleep aid.


Lion's Mane 150mg

Lion’s Mane is one of the most studied and potent fungi that is a powerhouse of nutrients and compounds that support optimal health and wellbeing.

It is anti-inflammatory and antioxidant, making it an invaluable ally in maintaining overall health and protecting your body from the damaging effects of oxidative stress from negative lifestyles, environmental toxins, and ageing.

It’s also renowned for improving cognitive health and has become a popular nootropic.

Benefits include:

  • Improving memory and focus.
  • Combats fatigue.
  • Promotes the growth of new brain cells.
  • Reduces
    inflammation and guard your cells against damage.
  • Digestive
    health improvements from the probiotics in the mushroom
  • Promotes
    growth of healthy bacterial supporting immune system.

Often used as a standalone supplement, it’s a welcome new
addition to this potent formula.



Korean Panax Ginseng 100mg

The word Panax means ‘all-healing’ which is derived from the Greek language.

It’s an antioxidant, an anti-inflammatory and an adaptogen that help’s the body deal with stress.

It is particularly well known for its successful use on many male
conditions including Erectile Dysfunction, libido, and virility.

Studies have shown that supplementation has seen premature ejaculation decrease and sexual performance improved in those who took Panax Ginseng.

From a hormone perspective, research has shown it has characteristics which protect the testes from toxins such as alcohol and physical trauma.

It has multiple additional benefits that include:

  • Anti-fatigue / energy boost.
  • Supports cognitive function
    & memory.
  • Improves libido.
  • Enhances blood flow.

Making it a fantastic ingredient
for our 55+ Grey Fox blend.


Saffron Flower Extract 15mg

Saffron is the most expensive spice in the world.

It’s a powerful antioxidant, gaining significant attention for its cancer preventive properties – particularly in prostate health.

It has been shown to inhibit tumour formation and prevent DNA mutations that can activate cancer genes in some studies.

An analysis of six studies showed that taking saffron significantly improved erectile function, libido, and overall satisfaction in men, making it a must have ingredient in all our formulas.

In addition, saffron

  • Provides protection for heart and blood vessel tissue.
  • Supports cognitive and mood disorders associated with aging.
  • Has multiple beneficial effects at a cellular level - making it a true “whole-body” supplement validating its centuries of use.

Piperine 2mg

Piperine is a beneficial plant compound found in black pepper that has numerous health benefits.

  • Enhancing nutrient absorption

The Secret to Super-Ageing

How hormones play a role in wellness & longevity and what all Grey Foxes need to look out for.

Impacts of ageing on hormonal health

We now know that in later life, testosterone deficiency is linked to a wealth of chronic health conditions and increases the risk of early death from all causes (British Medical Journal 2008).

It was also concluded during Covid that men with lower testosterone levels predicted the most severe clinical outcomes (Andrology, July 21) including a 6 x increased risk of death.

Therefore the notions that testosterone is only vital for sexual health and muscle building is outdated and far from the truth.

Modern research informs us that testosterone is vital for men’s health and plays a key role in immunity, disease prevention with higher levels being linked with optimal wellbeing.

By the age of 50, testosterone is depleting at 1-2% a year, and the daily exposure to toxins and oxidative damage at a cellular level is further impairing the body’s ability to produce and balance hormones effectively.

Metabolic conditions, including diabetes type 2 and obesity increase the chances of low testosterone by a further 25%.

Nutrient deficiencies are also more common at this age, impacting levels further. Poor diets and lifestyles mean that men simply do not have the raw materials available daily to maintain the 24 hour cycle of testosterone production.

The NHS reports that 50% of men over 50 take prescription meds daily. Many - including statins and blood pressure meds - are known to negatively impact testosterone health.

Its clear that strategic and targeted support is vital to maintain healthy hormones as you age.

Symptoms of low testosterone or deficiency

Although lowering testosterone levels is a natural sign of ageing - we know that there are many other factors driving levels lower or deficient that can be addressed.

Symptoms to be aware of include:

  • Decreased sex drive (libido) and other sexually related problems:
  • A decrease in the number and quality of erections.
  • Erectile dysfunction (ED)
  • Decrease in beard and body hair growth.
  • Decrease in muscle mass.
  • Development of breast tissue (gynaecomastia).
  • Loss of bone density (osteoporosis).
  • Declining cognitive function
  • Depression / Low Mood
  • Fatigue / Exhaustion
  • Poor Sleep
  • Loss of Confidence

As you can see, the symptoms are exhaustive and may be dismissed as just part of ageing.

However its vital that low testosterone is addressed and root cause acknowledged.

Prescriptions for ED will not do this and Testosterone Replacement Therapy is a life long treatment that replaces your bodies supply with synthetic hormones. This will not address any lifestyle issues driving the problem or address nutrient deficiencies etc.

How Grey Fox supports men’s wellbeing

Why choose DNA Products over another testosterone product?

We understand there are other "testosterone boosters" on the market that claim to help support healthy testosterone levels and we also know there are a lot of "snake oil" products out there and that is why DNA products are NOT a "testosterone booster" but a natural testosterone support supplement.

All DNA products are the only natural testosterone support supplement in a powder to liquid format which offers a 95% absorption rate of the 20 ingredients compared to only 30% absorption rate of pills and capsules which ALL OTHER testosterone products are. So DNA products not only have more ingredients and higher dosages, but have 3 times more the absorption rate making it unrivalled by any other product.

All DNA products were formulated by two Hormonal & TRT expert physicians and clinical nutritionists using clinical grade, natural ingredients and developed and manufactured in a FDA approved facility in the United Kingdom under stringent quality control measures to ensure all our products are to the highest possible standard.

DNA products are also the only natural testosterone products with over 100 European Food Safety Authority claims on each product so our clients can rest assured DNA products are as safe as they are effective.

How and when do I use DNA Products?

All DNA products are designed to support your natural testosterone production cycle which is on a 24 hour cycle and therefore needs to be taken daily.

For best results, take your DNA daily drink first thing in the morning when your Cortisol is at its highest.

Mix 2 teaspoons of DNA power powder into 150ml of cold water and stir.

Because of the high amount of ingredients and dosages, you might find a little residue at the bottom of the glass.

Simply add a little more water, stir and drink.

DNA products are designed to tackle the no1 cause of low testosterone which is micronutrient deficiencies and dependant on how severe your deficiencies are and how many vitamins and minerals you're deficient in, it can take between 2 weeks and 6 months to start feeling the effects of healthy natural testosterone levels although most clients report a significant increase in energy, mood and sleep quality after about 3 weeks of daily use.

It's important to note that low testosterone can't be fixed overnight and even TRT (Testosterone Replacement Therapy) which is a pharmaceutical intervention and a synthetic hormone can take up to 6 months to be effective and why GP's will not prescribe it for any less than 6 months.

All DNA products have the highest safe dosages of ingredients to ensure you start feeling the benefits as soon as possible.

What's in DNA Products?

All DNA Products have a base formula of ingredients that are all scientifically proven to increase natural testosterone production.

As DNA products are age specific, although each has a base formula of ingredients, a comprehensive list of ingredients can be found on the individual product pages.

Are DNA Products safe?

The answer is a resounding "Hell YES".

DNA only uses the highest grade of natural ingredients and is completely safe with no side effects.

All DNA products are manufactured in an FDA approved facility right here in the United Kingdom under stringent health and safety compliance.

DNA products are the ONLY natural testosterone supplement to have over 100+ EFSA (European Food Safety Authority) claims on each product.

If you are unsure however, please consult your GP before starting any healthy regiment.

Who are DNA Products for?

Our natural testosterone production peaks at around 19 years of age, and then declines at approximately 1% - 2% every 10 years.

That is why DNA have developed the world's first, age specific liquid testosterone support supplement range as your testosterone needs at 25 are vastly different to that of when your 60 and DNA products take this change in needs into account and offering natural solutions with our age specific range.

Under no circumstances should anyone under the age of 25 be taking any sort of testosterone supplement and why DNA actively distance ourselves from other "testosterone boosters" who all try and push their products on men as young as 18 which is morally and ethically questionable.

If you are experiencing the following symptoms then DNA products are definitely a natural, safe option to address these symptoms:

  1. Low/No Energy.
  2. Always Tired / Fatigued.
  3. Low Mood / Mood Swings
  4. Unmotivated or lack of drive.
  5. Over emotional.
  6. Low / No libido - Lack of interest in sex.
  7. No drive to workout or do things you normally enjoy.

If so, you could be dealing with an imbalance of hormones which could result in lower testosterone levels and higher oestrogen levels.

DNA products are natural solutions that can be added to your daily routine with minimum fuss or effort and in doing so, increasing your natural testosterone levels which will make you feel like yourself again.

Do I need to cycle DNA Products?

The good news is NO!

Because DNA is made with all natural ingredients and unlike all other testosterone products that contain fillers, binders and caking agents to manufacture pills / capsules, there is nothing in DNA products that can mess with your physiology.

We recommend that you take your DNA products daily to support your natural 24 hour cycle testosterone production and to feel all the benefits of healthy testosterone levels.

Do I need a doctor's prescription for DNA Products?

No prescription is needed for any DNA products.

DNA products contain only natural ingredients and do not contain any synthetic hormones or medications and is therefore completely safe to take on a daily basis with no known side effects whatsoever.

How long will it take my DNA Products to start working?

As every individual is different, results can vary vastly from person to person.

However, the majority of DNA MANIMALS (what we call our clients) start to notice positive effects including more energy, increased stamina, increased mental focus, increased muscle mass, improved libido and lifted mood in as little as 3 to 4 weeks when taken daily in conjunction with a healthy eating plan and regular exercise.

It can however take up to 6 months to start noticing the effects of healthy testosterone levels depending on lifestyle factors and why we recommend a monthly subscription to ensure consistency and in doing so, giving your body the maximum potential to produce healthy levels of testosterone.

Can I take DNA Products with other medications?

The default answer is yes, but if you are on other medications, please consult your GP before taking DNA products.

All DNA products contain only natural ingredients with no contra-indications to any medications but we always recommend consulting your GP just to be safe.

Do I still need to take Multi-Vitamins if I am taking DNA Products?

The great news is no!

As all DNA products double up as a multi-vitamin, you no longer have to try and swallow hand fulls of pills and capsules.

DNA products take care of all of this for you in one simple daily drink.

Why should I trust DNA when I have been stung by past "snake oil" products?

We do find it sad that we have to put this in our FAQ's but with all the BOGUS products out there we fully understand.

Did you know that AMAZON did an audit on their platform and found that 99% of testosterone products being sold on their platform either made false claims about their product, were made in unregulated facilities or simply didn't work.

That is why AMAZON banned all "testosterone boosters" from advertising their products on AMAZON.

DNA are one of the very few that are still permitted to advertise on AMAZON due to our stringent manufacturing process and EFSA (European Food Safety Authority) compliance.

DNA is also the only natural testosterone supplement in the world that is sold by Boots, one of the UK's most trusted wellness retailer as we are the only one that passed their vigorous compliance procedures.

All DNA products are developed by Hormonal and TRT Specialist Physicians and Clinical Nutritionists.
