Inside every testosterone-boosting serving of Testogen is…

D-Aspartic Acid

(2352mg)

D-aspartic acid (D-AA) is an amino acid that supports the production of luteinizing hormone in the pituitary gland. Luteinizing hormone stimulates the Leydig cells in your testes to produce and release testosterone1, 2, 3. By increasing your luteinizing hormone levels, D-AA can significantly boost your testosterone production.

Men taking a daily D-AA supplement showed a 15% increase in testosterone levels after just 6 days and a huge 42% increase after 12 days4

The same study showed a 33% lift in luteinizing hormone after 12 days

3 days after they stopped taking D-AA, men in the above study still had, on average, 22% higher testosterone levels than at the beginning of the study

After taking D-AA for 28 days, overweight men with low testosterone levels had testosterone increases of over 20% and reported significantly better energy levels, libido, mood and vitality5

Because it plays such a vital role in testosterone production and is backed by such strong evidence supporting its powerful testosterone-boosting effects, Testogen contains more D-AA per serving than any other product on the market.

Fenugreek Extract

(40mg)

Fenugreek contains compounds called furostanolic saponins which are believed to boost testosterone production by inhibiting the enzymes that convert testosterone into estrogen. Numerous studies have shown fenugreek to improve both testosterone levels and overall symptoms of low T, with study volunteers experiencing significant improvements in their energy levels, strength, body fat, mood, libido and overall feelings of well-being.

In a study of 50 men, a daily fenugreek supplement increased testosterone levels by up to 46% in 90% of the men after 12 weeks, and improved their energy, mood and libido6

In men aged 43-75, a daily fenugreek supplement increased both free and total testosterone and improved their libido within 12 weeks7

A twice daily fenugreek and chinese bush clover extract increased testosterone up to 10.38% after 4 weeks and 14.28% after 8 weeks. It also improved men’s overall symptoms of low T8

Fenugreek also supports

Energy

Libido

Strength

Mood

Fat loss

After 12 weeks, men taking fenugreek extract reported improvements in their energy, mood, mental alertness and libido9.

Fit men taking a daily fenugreek extract and working out 4 times weekly experienced significantly improved upper and lower body strength and reduced body fat compared to those taking a placebo10.

Men taking a daily fenugreek extract and strength training 4 times a week in a different study experienced a boost in testosterone levels compared to those taking a placebo, as well as a 2% reduction in body fat11.

Men aged 25-52 taking a daily fenugreek for 6 weeks enjoyed an increase in their sex drive. They also had more erections, had sex more often and had better orgasms12,13.

Vitamin D3

(50mcg)

Studies have shown that men with sufficient vitamin D levels have significantly higher testosterone than those with low levels23. Which means your testosterone levels could be affected if you’re not getting enough vitamin D. Your daily serving of Testogen will ensure you get the vitamin D you need to support healthy testosterone production.

A yearlong study with vitamin D deficient men found that doubling vitamin D intake increased free testosterone levels by 20.27% and total testosterone levels by 25.23%24

In a 2018 study, increased vitamin D intake in older men enhanced free testosterone levels by 18.87% and significantly decreased SHBG25, a protein that prevents testosterone from being used by the body, by 7.45%

A 2015 study with male Special Operations soldiers at Womack Army Medical Centre in Fort Bragg showed that low vitamin D levels were strongly linked to lower testosterone levels26

Testogen uses vitamin D3 (cholecalciferol) which studies have found is the more effective form of vitamin D to supplement with27. What’s more, vitamin D works even better when taken with magnesium, boron and vitamin K, which are all included in the Testogen formula too.

Vitamin D also supports

Energy

Performance

Sexual Function

Mood

Studies have shown that vitamin D significantly reduces fatigue28. That’s because vitamin D improves the activity of mitochondria - the ‘power stations’ of your cells29 - which boosts your energy levels.

By increasing the amount of energy available to your cells30, vitamin D can help your muscles work more efficiently. By simply increasing their vitamin D intake, professional soccer players performed better after 6 weeks31 and normal, healthy adults improved their cycling performance by 30% after just 2 weeks32.

A 2018 study conducted with 114 men found that increased vitamin D intake was significantly linked to improved erectile function33. This may be because vitamin D stimulates nitric oxide production34, which is vital to the erection process.

Studies have shown that people with anxiety and depression are more likely to be vitamin D deficient and that people with depression experienced a significant improvement in their symptoms after taking vitamin D35, 36. Which suggests that vitamin D plays an important role in supporting your mood.

Zinc

(10mg)

Zinc plays such a vital role in testosterone production that even a mild deficiency can interfere with your testosterone levels14. Yet most men don’t get enough of this essential mineral in their diet. Which means you’re probably not getting enough of it either. The zinc in Testogen helps protect you against zinc deficiency, supporting healthy testosterone levels.

An eye-opening study found that testosterone levels in young men on a low zinc diet plummeted by a shocking 75% within just 20 weeks15

The same study also showed that when older men increased their zinc intake for 6 months, their testosterone levels increased by almost 50%

Athletes taking a daily ZMA (zinc, magnesium, vitamin B6) supplement for 8 weeks showed a 33% boost in free testosterone levels16

In a study of 88 men aged 40-60, those with normal testosterone levels had significantly higher zinc levels compared to the low testosterone group17

Zinc’s dramatic effect on testosterone production may be due to its role as an antioxidant. Your leydig cells, which produce testosterone, are particularly vulnerable to oxidative damage18. Damaged leydig cells cannot produce testosterone as efficiently, leading to a drop in T levels. By helping protect your cells from oxidative damage, zinc helps support healthy testosterone production19.

The Testogen formula uses Zinc citrate, because it’s been proven to be better absorbed than other sources of zinc20.

Zinc also supports

Energy

Performance

Libido

Zinc is needed to form hemoglobin, which transports oxygen around your body, and insulin, which is crucial for blood sugar regulation. It also helps to break down and generate energy from food. The zinc in Testogen will help support your energy levels and ward off tiredness and fatigue.

Zinc is lost through sweat, so the more active you are the more likely you are to become deficient. Your daily dose of Testogen will keep your zinc levels topped up to help ensure your performance at the gym doesn’t suffer.

Research with male elite athletes has also shown that exercising to exhaustion can cause a temporary drop in testosterone levels. But zinc prevents this, leading researchers to conclude that zinc may benefit physical performance21.

Rats given 5mg of zinc per day demonstrated improved sexual behaviour and sexual function, suggesting that zinc may have a positive effect on libido and erections22.

Korean Red Ginseng Extract 4:1

(40mg)

One of the world’s most popular natural medicinal herbs, Korean ginseng (also known as Panax ginseng) has been found in studies to enhance testosterone levels. But the main reason it’s in Testogen is because of it’s proven libido-boosting benefits.

In a study of 66 men, ginseng increased free and total testosterone, luteinizing hormone (which stimulates testosterone production), and DHT (a more powerful hormone than testosterone)37

Studies on men with ED have shown ginseng to improve libido by almost 30%, erectile function by 37.67% and men’s overall satisfaction with their sex life by 33.79% after just 8 weeks38, 39

Men treated with Korean red ginseng enjoyed a 60% improvement in ED symptoms, compared to only 30% with a drug specifically designed to treat ED40

Experts believe that compounds in ginseng called ginsenosides are to thank for it’s beneficial effects on your sex life. Ginsenosides increase levels of dopamine and acetylcholine in the brain41, neurotransmitters which are linked to desire and arousal. Ginsenosides are also thought to improve nitric oxide production42, boosting the flow of blood to your penis and enhancing your erections.

Korean red ginseng also supports

Energy

Performance

Mood

Cognitive function

Fat Loss

Studies have shown that people taking ginseng experience more energy throughout the day43,44. This could be because molecules in ginseng like polysaccharides and oligopeptides reduce oxidative stress and increase energy production in cells, helping you fight fatigue45,46,47.

A paper published in The American Journal of Clinical Nutrition concluded that ginseng may enhance physical performance, especially if you are over 40 years old48.

Studies have shown ginseng to significantly improve mental performance, math skills and memory, as well as reduce feelings of mental fatigue49,50,51.

People taking Korean ginseng extract reported that their mood had improved and rated their quality of life much better compared to when they took a placebo52.

Studies have suggested that Korean red ginseng may increase fat breakdown and prevent the formation of new fat cells, which means it could help support your weight loss efforts53, 54

Boron

(8mg)

Boron is believed to increase testosterone metabolism55. Which means more of the total testosterone in your body is converted into free testosterone - the type that gives you all the benefits.

Studies have shown that even a small amount of boron is enough to significantly boost testosterone levels and decrease estradiol levels. Estradiol is a type of estrogen, and too much of it can cause your testosterone levels to decline.

Boron also reduces SHBG levels in your blood . SHBG binds itself to testosterone, preventing it from being used by the body. By reducing SHBG, boron frees up more testosterone to keep you energized, strong and focused.

A 2011 study revealed that men taking 10mg of boron each morning experienced a 28% increase in free testosterone in just one week56

The same study found that boron also reduced estradiol levels by 39% in one week

Just 6 hours after taking a single 10mg boron supplement, SHBG levels dropped by 9% in men in the above study

Boron isn’t just a powerful testosterone booster. It also significantly improves the absorption of the magnesium and vitamin D that are also in the Testogen formula57. Which means that boron makes the magnesium and vitamin D even more effective.

Boron also supports

Cognitive function

Research has suggested that boron may play an important role in healthy brain function and cognitive performance, especially as you age. In studies with healthy older people, those taking just 3.25mg of boron a day had improved attention and memory and were better at eye-hand coordination tasks58.

Nettle Leaf Extract 4:1

(40mg)

Stinging nettle roots contain compounds called ligans which prevent a protein called SHBG (sex hormone binding globulin) from binding itself to testosterone 59, 60, 61.

Once testosterone is bound to SHBG your body cannot use it and it becomes useless. By reducing the amount of SHBG that binds with testosterone, stinging nettle allows more free testosterone to circulate around your body.

In one study, stinging nettle ligans prevented the binding of DHT62, 63, an androgen hormone even more potent than testosterone, to SHBG by up to 67%

Research has also suggested that stinging nettle may help stop testosterone from being converted into estrogen64. By reducing the amount of testosterone that is converted into estrogen, stinging nettle can help keep your testosterone levels higher for longer.

Magnesium

(200mg)

Studies have shown magnesium to increase both free and total testosterone, with men who exercise benefitting from the biggest increase. Which means the more active you are, the bigger the testosterone-boost you’ll get from magnesium.

Men receiving daily magnesium supplementation for 7 weeks experienced a significant increase in testosterone compared to those receiving a placebo65

4 weeks of magnesium supplementation enhanced total and free testosterone levels in both active and sedentary men, with higher increases in the men who exercised66

Researchers monitoring the magnesium levels of 399 older men found that men with higher magnesium levels also had higher testosterone levels67

Despite the link between magnesium and testosterone production and the vital role it plays in many other physiological functions within the body, research shows that most men don’t consume enough magnesium, with older men in particular at higher risk of deficiency68. Which is why we’ve added a generous 200mg dose to every Testogen serving, to ensure you get enough to support continued healthy testosterone production.

Magnesium also supports

Energy

Performance

Strength

Mood

Sleep

Magnesium is needed for energy production. Studies suggest that low levels may interfere with your body’s ability to efficiently use energy stores69. The magnesium in Testogen will help keep your energy levels stable and prevent tiredness and fatigue.

Magnesium can boost your exercise performance by increasing the amount of glucose available to your muscles and the removal of lactate from muscles70. In one study, triathlon athletes taking magnesium for 4 weeks had faster running, swimming and cycling times71.

During a 7 week strength training program, people taking a magnesium supplement experienced significantly bigger strength increases compared to those taking a placebo72.

Magnesium is involved in the production of serotonin, the “happy” hormone that stabilizes your mood, feelings of well-being, and happiness. One study found that 450mg daily was as effective at improving mood as an antidepressant drug73.

Magnesium improves your sleep quality, which is vital for healthy testosterone production, energy, muscle growth and your overall health and wellness. A 2012 study showed that people taking a daily magnesium supplement slept significantly better than those taking a placebo74.

Vitamin B6

(20mg)

Studies have shown that vitamin B6 deficiency is linked to lower testosterone and increased estrogen levels75, which strongly suggests that vitamin B6 is vital to the testosterone production process.

Vitamin B also plays a crucial role in your overall health and wellness. Your body is unable to store vitamin B, so you must receive a daily dose. It’s important to increase your intake of vitamin B6 as you get older, especially for testosterone production, which declines as you age.

Vitamin B6 also supports

Energy

Mood

B vitamins contribute to a normal, energy-yielding metabolism76. The daily dose of vitamin B6 you’ll get with Testogen will support your energy levels and help reduce tiredness and fatigue.

B vitamins convert amino acids into mood-boosting chemicals like serotonin and noradrenaline77. With Testogen, it won’t be long before you’re feeling more like yourself again.

Vitamin K1

(20mcg)

Vitamin K helps your body absorb the vitamin D in the TestoGen formula more efficiently. Which means it increases the vitamin D’s testosterone-boosting effects.

Vitamin K also supports

Mood

Cognitive function

A 2019 study analysed 4,375 people aged between 45-79 and found that those with the highest vitamin K intake were significantly less likely to have symptoms of depression78. Which means that vitamin K may play an important role in supporting your mood.

Studies have shown that people over 70 with the highest vitamin K intake have better cognitive performance and memory in tests79, Which suggests that vitamin K could play an important role in keeping your brain functioning healthily, especially as you age80.

Bioperine® 95% Piperine

(5mg)

Bioperine is derived from black pepper and increases the bioavailability of Testogen’s ingredients by up to 30%81.

This means that your body is able to absorb and use up to 30% more of each of the active ingredients in Testogen than it would do without the Bioperine.

In other words, the Bioperine increases the effectiveness of Testogen, which means you get better results.
