Description

Testro Core™ is packed with over 10 efficaciously dosed, research backed natural testosterone enhancers designed to promote all things males in you. This powerful formula helps support increases in circulating testosterone while also blocking the body’s production of estrogen.  Low testosterone levels can wreak havoc on your body and can cause undesirable side-effects such as fatigue, loss of muscle mass/strength, an increase in body fat, and low libido. Regardless if these low levels are due to normal aging, excess weight, stress, or other variables it is vital that steps be taken to maintain or increase this anabolic hormone’s levels in the body when below a normal range. When you really want help increasing your body’s natural testosterone levels, you want proven ingredients that enhance testosterone safely and effectively. The comprehensive ingredient profile found in Testro Core™ will assist in maximizing natural testosterone output and promote a superior muscle building environment.

Key Ingredients/Benefits:

  • 1000mg Tribulus Terrestris – One study found men supplementing with Tribulus for 60 days were able to increase testosterone by 16.3%.
  • 500mg Fenugreek Extract – Supports increases in circulating testosterone.
  • 250mg Horny Goat Weed Extract – Shown in one study to increase testosterone levels by 3x over a 7-day period compared to a control group.
  • 100mg Polygonum Cuspidatum – In a study published in 2008 polygonum was found to increase blood testosterone correlation by 51.6%.
  • 100mg Maca Extract – Helps block the body’s production of estrogen while boosting testosterone levels.

Ingredient Profile : 

Boron:

Boron is what is known as a trace mineral. This means that our bodies benefit from it as a vital nutrient, but only in very, very small trace amounts.

• Boron has been implicated in increasing free testosterone and serum DHT levels.
• At the same time boron acts as an anti-estrogen and decreases sex hormone binding globulin (SHBG).
• A study conducted by Naghii et al. (2011) found men who supplemented with boron for 7 consecutive days increased free testosterone and dihydrotestosterone (DHT) levels by 28% and 10% respectively, while also decreasing free estrogen levels by 39%.

Zinc:

Zinc is vital for several important physiological roles in the body and is needed for many enzymatic reactions including those necessary to stimulate muscle protein synthesis.

• Zinc deficiency has been linked to low IGF-1 Levels and Growth Hormone.
• Zinc also supports optimal testosterone levels and may increase testosterone at rest and after exercise.
• A 2006 study by Killic et al. found wrestlers who supplemented with Zinc for 4 weeks were able preserve circulating testosterone and thyroid hormone concentrations, which declined in placebo due to the exhaustive workload.

Magnesium:

Magnesium is an essential mineral and electrolyte. It is involved in protein synthesis, ATP formation, metabolism of carbohydrates and fats, and bone strength.

• Magnesium deficiencies are the second most common deficiency in developed countries. A lack of magnesium will raise blood pressure and reduce insulin sensitivity.
• Increases in free and total testosterone have been noted in sedentary and athletic populations when supplementing with magnesium supplementation. It also acts as a muscle relaxer and may improve aerobic performance.
• Brilla et al. (1992) discovered 26 untrained subjects who participated in a 7 week strength training program in conjunction with magnesium supplementation were able to increase testosterone relative to baseline.

Vitamin B6:

B6 is a water soluble vitamin that is important to various metabolic reactions that occur in the body. It is also a coenzyme for protein metabolism and nervous and immune system function.

• B6 is also involved in the synthesis of hormones and red blood cells.
• Vitamin B6 may have some benefits with regard to increasing the rate of synthesis of testosterone.
• B6 may also be able to increase levels of growth hormone.

Tribulus:

Tribulus is an herb that is mostly recommended for male health including virility and vitality, and specifically more catered towards cardiovascular and urogenital health.

• It is a common supplement for its libido enhancing properties and testosterone boosting properties.
• The theory behind tribulus is it elevates luteinizing hormone, which in turn sends instructions to the testes causing them to make testosterone.
• Sellandi et al. (2012) found in men supplementing with tribulus for 60 days were able to increase testosterone by 16.3%.

Fenugreek Extract:

Trigonella foenum-graecum, commonly known as fenugreek, is a popular herb in Arabic regions and India. It has traditionally been used to enhance libido and masculinity.

• Fenugreek has been shown to increase testosterone in healthy males, which is thought to be due to a backlog of testosterone conversion into DHT via inhibiting the 5-alpha reductase enzyme.
• Fenugreek has also been used to alleviate blood sugar metabolism problems like diabetes.
• A human study done by Wilborn et al. (2010) noted that fenugreek supplementation led to increases in testosterone and bio-available testosterone, while also decreasing body fat.

Macuna Pruriens:

Increases L-Dopamine which stimulates testosterone synthesis and growth hormone secretions.

Horny Goat Weed Extract:

Horny goat weed that is often used as an erectile aid and aphrodisiac.

• It seems to have the mechanisms to increase testosterone, but no human studies exist on the subject matter.
• Horny goat weed was shown in one rat study to increase testosterone levels by 3x over a 7-day period compared to a control group.

Diindolylmethane (DIM):

DIM is a molecule that consists of two indole groups attached to a methane group. It is commonly found in broccoli and hold promise as an aromatase inhibitor.

• DIM has potent effects on estrogen metabolism and is able to keep the body relatively balanced by preventing either drastic increases or decreases in estrogen.
• DIM can both inhibit the aromatase enzyme (and prevent conversion of testosterone into estrogen) and it can act on more potent forms of estrogen and convert them into less potent forms; this conversion reduces the overall effects of estrogen in the body.

White Button Mushroom:

White button mushroom can be used to drive down estrogen levels via inhibiting the aromatase enzyme.

• Researchers at Beckman Research Institute, found out that that an extract prepared from white button mushrooms decreased the activity of aromatase enzyme and estrogen levels in a dose dependent manner.

Maca 4:1 Extract:

Maca is a plant in the broccoli family. Maca has traditionally been used as an aphrodisiac.
• Men supplementing with maca have been known to experience an increase in sperm production. Maca also appears to be a potent suppressor of prostate hypertrophy.
• Preliminary research also suggests maca can protect the brain from damage, improve bone health, and even improve cognitive ability in healthy people.

Polygonum Cuspidatum (20% Resveratrol):

Resveratrol is a member of a group of plant compounds called polyphenols.

• Resveratrol may increase testosterone levels in the blood and may be an agonist for androgen receptors.
• Research suggests that Resveratrol may have an anti-aromatase effect on testosterone, meaning that it does not get converted into estrogen at the same rate.
• In one study published in 2008 in the Archives of Pharmacal Research, Resveratrol was found to increase blood testosterone correlation by 51.6% in mice.
