Distributed by Phenom Health, TestX Core is one of the newest performance enhancing supplements to appear on the fitness scene. TestX Core claims to deliver increased muscle mass, shorter recovery time between workouts, better hormone production, enhanced sexual stamina, and more intense workouts.1
While there has been some media attention surrounding TestX Core, Shark Tank was not one of the media outlets where the supplement has been featured.
If you’re still wondering, “what is TestX Core?”, you’re not alone. This TestX Core review is designed to provide you with insight on how TestX Core works, what ingredients go into each serving, and what side effects to expect during use.
TestX Core Ingredients
The Phenom Health TestX Core supplement includes 18 ingredients, using minerals, vitamins, and plant extracts with ties to both Eastern and Western medicine. We will break down each ingredient and explain how it works as part of the TestX Core performance enhancement blend.
Magnesium (Magnesium Citrate): 112.5 mg – Magnesium is a chemical element found in foods such as dark leafy greens, beans, avocados, and fish. Magnesium supplies in the body are known to deplete during exercise, and have been proven beneficial to the enhancement of exercise tolerance and heart health.3
Saw Palmetto (Serenoa Repens) [4:1]: 62.5 mg – Saw palmetto, a fruit extract, has been used as a treatment for benign prostatic hyperplasia (enlarged prostate). However, studies have shown that saw palmetto also improves sexual performance in men.4
Panax Ginseng Root Extract [10:1]: 12.5 mg –A native plant of Southeast Asia, panax ginseng root extract is used in TestX Core for its ability to enhance physical endurance. One of the proven benefits of Panax ginseng root extract in animal studies is its anti-fatigue properties.5
Tongkat Ali (Eurycoma Longifolia Root): 100 mg – Also known as Malaysian Ginseng, Tongkat Ali is a plant native to Southeast Asia. The root is harvested and used for medicinal purposes involving the libido. Most studies involving Tongkat Ali have been performed on animals, but one 2011 human study found that the root was successful in improving testosterone levels in aging males.6
Zinc (Zinc Monomethonine): 7.5 mg – Zinc is a chemical element used in the human body to regulate blood clotting, thyroid response, the immune system and more. It has also been linked to male testosterone, and plays a part in the regulation of serum testosterone levels.7
Vitamin B6 (Pyridoxine Hydrochloride): 2.75 mg – Vitamin B6 supports the adrenal system, and can be found in protein rich foods, such as fish, beef, and turkey. Animal studies have shown that B6 in large quantities can promote muscle growth.8
Fenugreek (Trigonella Foenum-Graecum) Seed: 2 mg – Fenugreek is a seed commonly used in Indian cooking, which also provides several medicinal benefits to users. One benefit uncovered during a human study in 2004 is its ability to increase muscle regeneration after exercise.9 Fenugreek extract has also shown promise as a natural testosterone and libido enhancer.10
Lycopene (All-Trans Lycopene): 3.25 mg – It contains high levels of antioxidants and is thought to prevent a variety of diseases, such as cancer and heart disease.17 Lycopene has also ben used in male infertility trials and successfully elevated sperm count and mobility in men.18
Astaxanthin (Haematocuccus Pluvialis): 1 mg – Like lycopene, astaxanthin is a red-pigmented carotenoid. It occurs naturally in pink and red hued sea life, such as salmon and shrimp. In animal trials astaxanthin was successful in reducing the damage to muscle tissues, including the heart, following rigorous exercise.19
Tribulus (Tribulus Terrestis Fruit): 1 mg – Animal trials using tribulus, a natural fruit extract, have been successful in decreasing fatigue in subjects following exercise.20
L-Arginine: 1 mg – An amino acid found in foods like turkey, pumpkin seeds, and soybeans, L-arginine, has shown promise to increase blood flow and exercise performance in those who ingest it.21
Taurine (2-Aminoethanesulfonic Acid): 1 mg – An organic compound used in a variety of energy products, taurine has anti-fatigue properties which help prolong exercise in animal studies.22
Boron (Boron Citrate): 1 mcg – Boron is a chemical element found in diets rich in nuts, vegetables and fruit. Research suggests a link between boron and reduced inflammation, hormone management, wound healing, bone density, and magnesium absorption.23
Vitamin C: 3 mg – A vitamin found in a variety of fruits and vegetables, vitamin C has a strong potential as a pre-workout supplement. Studies show it can reduce muscle soreness when consumed before exercise.24
Folate: 50 mcg – Folic acid is a B vitamin, which plays a role in protecting cells and DNA. Studies have shown that folate deficiency causes DNA damage. Its use in TestX Core could be as a protectant during high impact physical activity.25
Selenium (Selenomethione): 10 mcg – Selenium is a chemical element found in foods such as brazil nuts, beef liver, sardines, and halibut. Studies show that selenium plays a role in sperm production and motility in infertile men.26
Vitamin D (Cholecalciferol): 2 mcg – Vitamin D, found in foods like beef liver, fatty fish, and egg yolks, are used in athletic supplements for its ability to improve strength and balance.27
Vitamin B12 (Methylcobalamin): 1 mcg – B12 is found in foods like eggs, meat and shellfish. It works in conjunction with B6 and folate to increase iron efficiency, produce red blood cells, and assist the body in properly utilizing fat and protein, which is important when building muscle.28
How to Use Phenom Health TestX Core
The TestX Core supplement website instructs users to take 2 capsules daily with a full glass of water. TestX Core is to be taken with food, and should not be used by those with serious medical conditions without a doctor’s supervision.
TestX Core Side Effects
Is TestX Core safe? While the Phenom TestX Core website claims that TestX Core is all-natural and causes no side effects, some users may experience adverse effects if they have a sensitivity to one or more ingredients.2
Saw Palmetto rarely causes side effects, but sensitive users have experienced headaches, dizziness, nausea, and diarrhea.11 In extreme high doses magnesium can cause severe reactions such as slowed breathing, coma, cardiac arrest, respiratory paralysis, and low blood pressure. Less severe responses include dizziness, vomiting, confusion, and nausea.12 When used in doses of more than 100 g per day, fenugreek can cause gastrointestinal symptoms.13 Rare cases of sensitivity to vitamin B6 has caused skin reactions, including sensitivity to sunlight; other mild gastrointestinal symptoms may also occur.14 In the small levels found in TestX Core, boron shows no side effects in human studies.15 With extremely high doses, over time, selenium can cause deterioration of fingernails, skin rash, weight loss, fatigue, and irritability.16
When used as directed, the ingredients in TestX Core should cause little to no side effects unless an allergic reaction occurs.
