Why Do I Want Extra Testosterone?

Testosterone is one of the most important hormones produced by the body, particularly for males. Not only is it vital to maintaining proper musculature and masculine appearance, it has myriad psychological benefits as well. Lastly, strong, healthy levels of testosterone are important to maintaining optimal libido, including both sex drive and performance. T+™, when combined with an athletic regimen that preferably includes an anabolic component (like squats!) is designed to assist the body with naturally elevating testosterone levels.†

6 Time World Record Holding Powerlifter Casey Williams

Pittsburgh native Casey Williams previously played football at Division 1- FCS Bucknell University where he was nominated the 2010 NSCA All-American Strength and Conditioning Athlete of the year.

He is new to the sport of powerlifting, but not new to the record book. Casey set the all-time, drug-free, raw total in the 220 lbs. class for any federation. Yes, Casey was drug tested on site. He also set 3 IPA World Records in the Mens' Open Raw division at 24 years old. He still holds 3 Junior IPA World Records as well.

His lifts in 2012 were: Squat: 700, Bench: 425, Deadlift: 685, TOTAL: 1770
(His 1770 is now an All Time drug tested record!)

How does this formula work?

There are three key aspects to this revolutionary formula:

Help the body boost internal testosterone production:

T+ has a three pronged approach to elevating endogenous testosterone:

  1. Mucuna Pruriens has been shown to help elevate natural dopamine levels, a key neurotransmitter involved in hormone synthesis.
  2. Eurycoma Longifolia (Long Jack) helps the body to enhance the synthesis of various androgens produced by the testes.
  3. Magnesium Aspartic Acid is a new compound currently awaiting research that combines magnesium (which is the key ingredient in ZMA® and has shown potential in its own right to help the body with testosterone production) with Aspartic Acid.

Help the body minimize excess estrogen:

Equally important to increasing free testosterone, is the ability to minimize excess estrogen so that the ratio remains favorable inside the body. T+ pays special attention to this fact by including the well documented ingredients Red Clover, Luteolin, Resveratrol, and Stinging Nettle Root. For more information on how these ingredients can help the body inhibit estrogen levels, click RESEARCH.

Assist with athletic performance:

Testosterone itself will help stimulate lean muscle growth, especially when combined with moderate to intense exercise. T+ also includes some of the building blocks to boost exercise performance and speed up recovery. Beta-alanine can help attenuate fatigue by helping the body increase intramuscular buffering capacity during high intensity exercise. T+ also includes 750 mg of Branched Chain Amino Acids (BCAAs), an essential dietary component to helping the body reduce muscle soreness.†

Will taking T+ affect my body's innate ability to produce Testosterone?

“The short answer is - the T+ formula helps to stimulate endogenous (internal and personal) testosterone production, whereas the exogenous (from the outside) Testosterone hormone supplementation (T, steroids, even Deer Antler) can and usually does significantly reduce personal production... often to the point of shutting it off. The body's feedback system says ‘Wow’ we have too much now (when given from the outside) so we don't need to make any more... a negative feedback loop.

The T+ provides the building blocks and stimulus for personal production so that men (and women) can help optimize their body's own usable Testosterone and therefore assist the body with longevity and vitality.”

Dr. Dan Engle

Is T+ Competition Safe?

All of our ingredients are completely safe for use in competition, however, different governing bodies have different rules on how much extra testosterone is allowed. Please use with your own careful consideration when utilizing this formula.

The age-associated decline in male testosterone is marked by non-specific characteristics that can affect quality of life and life expectancy[source]. Changes in body composition, decreased libido, changes in mood, and hair loss are possible indicators of declining testosterone production[source]. Prescription testosterone replacement therapy (TRT) can help alleviate these changes, however these medications can present with a host of side effects that range from wide mood swings, to accidental transmission to nearby individuals[source]. A simple and more effective strategy is to enhance the body’s natural testosterone production through dietary compounds known to affect key steps in testosterone synthesis. The T-Plus formulation utilizes natural compounds that have been shown to both improve the biochemical synthesis of testosterone and eliminate some of the common side effects of testosterone supplements.


Testosterone production begins with the brain. Muncuna pruriens has been shown to help the body elevate testosterone by increasing the production of the neurotransmitter, dopamine[source]. In addition to regulating mood and sex drive, dopamine plays a key role in hormone synthesis. In a study of males with fertility problems, Mucunca pruriens supplementation improved reproductive health and significantly elevated dopamine and testosterone production[source].

The Malaysian adaptogen, Eurycoma Longifolia (Long Jack), is another herbal aphrodisiac traditionally used to increase energy and vitality. The roots of E. Longfolia contain a variety of bioactive polypeptides that help the body enhance the synthesis of various androgens produced by the testes[source]. A study of older males consuming E. Longifolia showed a 46.8% average increase in testosterone after one month[source]. This increase in testosterone may account for the for other significant benefits of Eurycoma Longifolia, including increased bone density, fertility, and even quality of life outcomes in a double blinded study[source].

Lastly, magnesium is an essential dietary mineral for brain and bone health and has been shown to increase testosterone in competitive athletes[source]. T-Plus utilizes magnesium bonded to Aspartic Acid, creating a newly developed natural compound.


Once synthesized, free testosterone is released into the blood stream to reach its biological targets. However, free testosterone is quickly bound and inactivated by a circulating high-affinity carrier protein, Sex Hormone Binding Globulin (SHBG)[source]. Stinging nettle root helps the body compete with the binding of SHBG, allowing a higher proportion of testosterone to remain in the active, unbound form[source, source]. The combination of Eurycoma Longifolia and nettle root increases the probability of increased free testosterone reaching its biological target.

Testosterone exerts its effects on some targets, such as the brain and bones, by activating estrogen receptors on cell surfaces. Excessive conversion of testosterone to another sex hormone, estradiol, can lead to undesirable feminizing characteristics, hair loss, and low libido[source]. The T-Plus formula is designed to mitigate these negative effects by helping the body inhibit the conversion to estradiol and blocking estrogen receptors. Red Clover isoflavones and luteoline help suppress aromatase, the key enzyme that converts testosterone to estradiol [source, source]. In addition, the potent anti-oxidant resveratrol has recently been shown to exert anti-estrogenic activity by antagonizing a subset of estrogen receptors[source, source]. These three compounds together help prevent the unwanted side effects that can occur from elevated testosterone production.

Build and Recover

Testosterone will help the body stimulate lean muscle and increase bone density, especially when combined with moderate to intense exercise. T-Plus also provides the building blocks to boost exercise performance and speed up recovery. Beta-alanine can attenuate fatigue by increasing the intramuscular buffering capacity during high intensity exercise source]. T-Plus also includes 750 mg of Branched Chain Amino Acids (BCAAs), an essential dietary component to reducing muscle soreness[source].


T-Plus combines natural testosterone boosting ingredients with estrogen blocking compounds in order to increase endogenous testosterone production. These compounds have been tested in endurance competitors, body builders, and even combat athletes[source]. In addition to the numerous benefits of increased testosterone, T-Plus includes the amino acids directly involved in recovery and synthesis of new muscle tissue. For best results, include T-Plus as part of a pre-workout nutritional regiment.

*The above ingredient research is designed to provide a framework for you to make an educated decision on how T+ might be effective for you. Every person's natural hormone composition is different, and no results should be considered 'typical' or 'expected'.
