How Testosterone boosters work

Here’s the science bit.

Testosterone is what’s known as a steroid hormone. It’s what makes a man, a man. This starts before birth, which peaks with puberty, and then declines considerably with age.

Here are a few points in which you lose testosterone, along with the rate of loss:

Doesn’t look good, does it? It’s particularly bad news if physical fitness and muscles are important to you, but it will hit you in all sorts of other ways as well. You’ll face a downward spiral as your testosterone levels slump.

Tiredness and depression
Failing libido (not to mention your pride and joy in that department) however
Fat starting to build up around your waist
Your concentration and memory not what they used to be

TESTOGEN – SO WHAT’S IN IT?

Testosterone boosters in the form of LOTS of great, natural ingredients are in TestoGen, in just the right amounts to do the job properly. Take a look at these:

BIOPERINE

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

ZINC

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!

VITAMIN B6

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.

RED GINSENG EXTRACT

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

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

D-ASPARTIC ACID

is 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.

VITAMIN K1

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!

NETTLE LEAF EXTRACT

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.

BORON

is 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.

VITAMIN D

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.

MAGNESIUM

is 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.

IS THERE ANY PROOF OF THESE CLAIMS?

There has been plenty of clinical research relating to testosterone boosters over the years so you can be confident about getting good results. Check out this small sample of clinical studies:

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”.
