D-Aspartic Acid (2352mg)

An amino acid regulator which helps to produce hormones, including luteinizing hormone. This stimulates the production of testosterone and in turn, helps in the production of lean muscle and an overall increase in strength and stamina – and your libido will definitely get a kick from it! Research suggests that D-aspartic could enhance testosterone production by over 45% in a matter of weeks – and TestoGen has more of it per serving than any other product on the market.

Magnesium (200mg)

An essential nutrient that plays an important role in testosterone production. One study found that men taking 750mg of magnesium per day for four weeks showed a 26% increase in testosterone levels. Magnesium also helps promote quality sleep, which is vital for good testosterone production. Research shows that most adults don’t consume enough magnesium, so we’ve added a generous dose of to every TestoGen serving to ensure you get more than enough of it.


Vitamin D3 (50mcg)

Studies have shown that men with sufficient vitamin D levels have significantly higher testosterone levels than those with low vitamin D levels. Which means increasing your vitamin D intake can have a very positive effect on your testosterone levels. TestoGen uses vitamin D3, cholecalciferol, which can lift your free testosterone level (testosterone that is not attached to protein, so it’s floating around in your bloodstream) as well as slow down the rate of testosterone converting into oestrogen. It’s a win-win situation. What’s more, vitamin D works even better when taken with magnesium, boron and vitamin K, which of course, are all included in the TestoGen formula too.

Nettle Leaf Extract 4:1 (40mg)

You’ll know it by the name stinging nettle but did you know it can help boost your testosterone levels? Testosterone likes to bind itself to a protein called SHGB. But when it’s attached to protein, testosterone isn’t very useful. Research suggests that nettle leaf also binds to SHBG, leaving your testosterone free to circulate your bloodstream and do much more useful things like build muscle and boost your libido. 


Korean Red Ginseng Extract 4:1 (40mg)

is taken from the root of the plant and is a well-known aphrodisiac giving it the alternative name of “man root”. It is also a libido stimulator which can protect the testes from damage by dioxins, assisting in strong erections. In TestoGen it gives you a strong feel-good factor to sharpen you both physically and mentally, making you ready to tackle anything! 

Fenugreek Extract 4:1 (40mg)

A herb with libido-enhancing, testosterone-boosting seeds. Fenugreek is a safe, natural way to increase your strength, stamina and vitality. Fenugreek also has powerful antioxidant properties to ensure those harmful free radicals are kept at bay so your body can work efficiently. 


Vitamin K1 (20mcg)

The vitamin helps keep your bones strong and healthy, but the main reason we’ve included this important vitamin is because it helps your body absorb the vitamin D that’s also in the TestoGen formula more efficiently, increasing the testosterone-boosting benefits you’ll get from the vitamin D! 


Vitamin B6 (20mg)

is needed by the body for over 100 different functions, so it plays a crucial role in your overall health. B vitamins are also vital for the testosterone production process, and studies have shown that vitamin B deficiency is linked to lower testosterone levels and increased estrogen levels, as well as having an impact on overall energy levels. The vitamin B6 in TestoGen will help you combat tiredness and irritability as well as help your body produce more testosterone. 

Zinc (10mg)

is a really effective testosterone booster and well-known aphrodisiac; zinc is a major component of oysters. It’s also essential for keeping your sperm healthy and responsible for a whole lot of bodily functions working properly. You can lose zinc through sweat so it’s vital to keep your levels topped up if you are into fitness – or any other activity that makes you sweat!

Boron (8mg)

A trace mineral found in the earth’s soil and certain fruits and vegetables. Studies have shown that even a small amount of boron is enough to significantly increase testosterone levels. One study found that men who took 10mg of boron per week showed a 28% increase in free testosterone and a decrease in estrogen levels. In another study, male bodybuilders taking a daily boron supplement for seven weeks showed a significant increase in testosterone levels compared to those taking a placebo. 


Bioperine® 95% Piperine (5mg)

Is derived from black pepper and significantly increases the bioavailability of all the other ingredients in TestoGen. This means that more of the active ingredients are absorbed by your body, which makes them more effective. In other words, including Bioperine in the TestoGen formula means you get better results.

Don’t Take Risks

Your testosterone is slipping away every day and you want to do something about it, and fast. Sure, there are some ‘miracle cures’ out there but they don’t necessarily work so it could be good money down the drain. More of a worry, some of the ingredients might be untested and/or unsafe

TestoGen’s pure, natural ingredients mean you can rest assured there is nothing risky in there. You need to check product labels carefully because testosterone boosters are NOT all the same. Other products might contain risky, unproven ingredients, or ineffective unwanted substances, be in the wrong combination to work together or even be present at an unsafe quantity. Risks in similar products may include:
  • Using substances such as artificial flavourings or colourings, which some people can be allergic to. These could produce unwanted side effects including health issues.
  • There may be no proof that some of the listed ingredients have any beneficial effects, or back up to the claims being made for what the ingredient does.
  • There may be no indication of the daily recommended dose of the active ingredients compared to what is in the product. How do you know the daily dose is within guideline amounts?
  • If there is no money back guarantee on a product, perhaps the manufacturer/supplier has no faith in it, so why should you? You might be throwing your money away for nothing.
Don’t take risks with your health – take four TestoGen capsules every morning. Boost your testosterone levels quickly and easily with exactly the right amount of super-ingredients! TestoGen gives you everything you need to boost testosterone in a quick and easy way. You don’t have to bother about whether you have the right amounts of nutrients. There’s nothing to mix, nothing to measure, nothing to worry about.

Is There Any Proof Of These Claims?

1) Many studies have demonstrated a strong link between Vitamin D levels and testosterone levels. In one German study, a group of overweight men were put on a 12 month long weight loss program. They were divided into two groups. The first group received a placebo supplement and the second group was given vitamin D3 supplements. Not only did the men taking vitamin D lose on average 6 kilograms of weight, but they also showed a significant increase in testosterone levels; up to 25 per cent on average. Another study compared the vitamin D and testosterone levels of 652 Korean men over the age of 40 and found that those with a vitamin D deficiency were 2.65 times more likely to also have a testosterone deficiency.
2) Fenugreek – a study led by Australian scientist Elizabeth Steels in 2011 stated that fenugreek had: “a significant positive effect on physiological aspects of libido and may assist to maintain normal healthy testosterone levels”.
3) D-Aspartic acid was shown to boost testosterone in a study carried out by a team of Italian scientists in 2009 who concluded that “D-aspartic acid is a physiological amino acid occurring principally in the pituitary gland and testes and has a role in the regulation of the release and synthesis of LH and testosterone in humans …”
4) American scientist Luke Bucci found that “controlled studies of Asian ginsengs found improvements in exercise performance … improvements in muscular strength, maximal oxygen uptake, work capacity, fuel homeostasis, serum lactate, heart rate, visual and auditory reaction times, alertness, and psychomotor skills have also been repeatedly documented”.
