Gamma-O  Testosterone Booster






New Gamma-O

The Safest and Most Effective Natural Testosterone Booster - Now Stronger and More Potent than Ever Before!

Introduced in 2004, the original Gamma-O instantly became an underground phenomenon. So much so that despite being 100% non-hormonal, friends, family, and fellow gym members couldn't help but question the "natural status" of Gamma-O users. And now, it's even STRONGER.

Introducing Gamma-O. Founded on the same breakthrough pro-testosterone technology, it's now loaded with even more potent, scientifically researched ingredients to achieve what was only a dream a few years ago - that is, massive testosterone production and superior hormonal optimization for greater strength and size.



Maximum Hormonal Optimization

Modulate estrogen, increase testosterone activators, and give your body the building blocks it needs to flood your veins with raw, unadulterated levels of bioactive testosterone. +

Build ROCK HARD Mass & Gripping POWER

Elevated testosterone helps improve recruitment of force generating motor units inside muscles, which can lead to greater strength and muscular hypertrophy. +

Annihilate FAT - Not Muscle

Fat burning stimulants can eat through muscle like there's no tomorrow. Now you can protect your hard earned muscle and safely peel off the layers - without the stims - using New Gamma-O Natural Testosterone Booster. +

liquid pill


Hidden deep inside the molecular structure of Japanese rice bran is an extract called Gamma Oryzanol.

Rich in physiologically potent plant sterols and Ferulic Acid, Gamma Oryzanol is an all natural, non-hormonal compound with profound pro-testosterone capabilities. And when Gamma Oryzanol enters the blood stream, something incredible happens...

Gamma Oryzanol significantly increases testosterone production by increasing the body's key testosterone activator - Luteinizing Hormone. But there's a catch. Powdered Gamma Oryzanol is not easily absorbed by the human body. It must first be transformed into a rich liquid emulsion which is accomplished only by using state-of-the-art Liquid Emulsion Technology™. And near perfect absorption rate is achieved!

Gamma-O V2 Natural Testosterone Booster Nutritional FactsMeet Version 2.0!

True Innovation brings it ALL Together

The original Gamma-O changed the underground bodybuilding landscape forever. Yet when new breakthroughs in testosterone and hormonal optimization are discovered...breakthroughs that can help increase size, power, and performance...then it's time revolutionize all over again! Take a look at the exciting new ingredients found inside NEW Gamma-O!

Indole-3-Carbinol (I3C): Despite popular belief, estrogen isn't "evil." Yes, too much can lower testosterone, increase body fat, and lower sex drive. Yet men need estrogen to help build muscle and maintain a strong sexual drive. The key therefore isn't to obliterate estrogen, but to strategically modulate estrogen metabolism in your body.

You see, estrogen is metabolized through two pathways. One results in the formation 2-hydroxyestrone; the "good estrogen" due to its weak and low biological activity. The other creates 16-alpha-hydroxyestrone. This is the "bad," or rather..."nasty"...estrogen, as its biological activity is very strong.

That's why the new Gamma-O contains Indole-3-Carbinol. As a potent modulator of estrogen metabolism, it can help improve body composition by altering the ratio in your favor. +

Vitamin D3 (as Cholecalciferol): Did you know researchers following 2,299 men discovered those with more Vitamin D3 in their blood had higher testosterone levels? Likewise, they found that men with less D3 had less testosterone1.

This is important because most men are deficient in Vitamin D3, which is largely obtained by exposure to the sun. That's why NEW Gamma-O further supplies 3,000 anabolic IU's of pure Vitamin D3 every day to help support optimal testosterone production in the body. +

Maca Root Powder: Maca is renowned for it's adaptogenic benefits, which help the body better resist stress. Maca in particular is known to help balance and regulate the hormonal system, while simultaneously improving energy, endurance and sexual performance. This makes Maca a "must have" for anyone looking to pack on more size and power! +

  • How often should I take Gamma-O?

    Take 2 Liqui-Caps twice a day. Ideally you should take it the same time every day. For best results, take with food.

  • When should I expect to see results?

    Most people see results by the end of the first month. You will continue to feel added effects the longer you take it. All of our case studies had noticeable increases after 30, 60, and 90 days. After several months your body will have established a new base level.

  • Because Gamma-O increases testosterone, does it also cause "roid-rage"?

    No, Gamma-O increases your body's natural testosterone production. It is not synthetic testosterone, which can increase androgen levels thousands of times higher.

  • If I stop taking Gamma-O, will I have the same negative effects as if I came off steroids?

    No. Gamma-O helps your body produce more of its own natural testosterone. Steroids are a synthetic substitute that cause your body to shut down testosterone production. When you stop using steroids, it takes some time for your body to start producing its own testosterone again. During this lapse, your hormone levels drop substantially. When you discontinue Gamma-O, your testosterone levels will slowly return to normal baseline values. Because this process is suggested to take anywhere from 2-3 weeks, there is no crash due to a sudden loss of androgens.

  • I have seen Gamma Oryzanol in a powdered pill form. What is the difference between powdered Gamma Oryzanol and liquid emulsion Gamma Oryzanol?

    This is a very good question because you will find many reports of powdered Gamma Oryzanol not working. Here's why, and it's a very important distinction to understand. Gamma Oryzanol in a dry powder form has a very low absorption rate. If the body cannot absorb the molecule, it simply won't work. And in powdered form, it doesn't work. However, our breakthrough Liquid Emulsion Technology™ has enabled us to develop a unique process of transforming the powder extract into a liquid emulsion. The liquid has over 200 times more surface area, allowing the Gamma Oryzanol to quickly and effectively enter the bloodstream. This enables users to experience the tremendous beneficial effects of enhanced natural testosterone production.

  • Will Gamma-O help boost my red blood cells?

    None of our case studies specifically monitored RBC's. We do however believe your RBC's will increase because of the direct correlation between testosterone and RBC's. Additionally, our athletes noticed an increased pump during and after training, which suggests there is an increase in blood volume.

  • I am currently taking other supplements and vitamins. Can I continue to use these supplements while taking Gamma-O?

    Yes. Gamma-O has no known adverse reactions when taken in conjunction with other supplements.

  • Are there any side effects of Gamma-O Natural Testosterone Booster?

    No. Gamma-O has been proven safe and non-toxic. It is a rice bran extract that has been around for centuries.

  • Do you guarantee your product?

    Absolutely! This company was founded by athletes seeking a natural alternative to steroids and andro products. If for any reason you are not completely satisfied, we offer a money back guarantee.

  • Does your product increase the bio-available testosterone or just the overall testosterone?


  • Can you take Gamma O on an empty stomach?

    You can take Gamma O on an empty stomach or with a meal. Studies show it is more effective when taken with food. You should try to take it at the same time every day (hence every 24 hours)
