High T Customer Testimonials

High T Ingredients


Testofen is a patented blend of fenugreek extract. It is used in a number of testosterone boosting supplements.

According to a study published in The Aging Male, “This was a double-blind, randomized, placebo-controlled trial involving 120 healthy men aged between 43 and 70 years of age. The active treatment was standardized Trigonella foenum-graecum seed extract at a dose of 600 mg/day for 12 weeks. The primary outcome measure was the change in The Aging Male Symptom questionnaire (AMS), a measure of possible androgen deficiency symptoms; secondary outcome measures were sexual function and serum testosterone. There was a significant decrease in the AMS score over time and between the active and placebo groups. Sexual function improved, including number of morning erections and frequency of sexual activity. Both total serum testosterone and free testosterone increased compared to placebo after 12 weeks of active treatment. Trigonella foenum-graecum seed extract is a safe and effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged and older men.” [2]


Fenugreek is an herb native to southern Europe, the Mediterranean, and western Asia. The seeds are used for cooking, medicine, and to hide the taste of other medicine. The leaves are eaten in India. It smells and tastes somewhat like maple syrup.

It is taken by mouth to treat digestive disorders and problems such as constipation, upset stomach, loss of appetite, and gastritis. It is also used for diabetes, obesity, polycystic ovarian syndrome (PCOS), and conditions that affect heart health.  It can be used for kidney conditions, cancer, baldness, Parkinson’s disease, and exercise performance.

Some men use it to treat hernia, erectile dysfunction, and male infertility while women who are breastfeeding sometimes use it to promote increased milk production and flow. [3]

Eurycoma Longfolia Extract

Eurycoma Longfolia is a shrub tree native to Southeast Asia. Malaysian men claim that tee made with this plant improves their sexual ability and virility. This has led to such a demand for the plant that it is now considered a “protected” species.

The root and bark of the plant are used for treating erectile dysfunction, increasing sex drive, male infertility, boosting athletic performance, bodybuilding, and reducing body fat. It can also be used to treat fever, ulcers, high blood pressure, cancer, diarrhea, headache, cough, and tuberculosis. [4]

Rhodiola Rosea Extract

This is a plant whose root is used to make medicine and treat a wide variety of conditions, but there isn’t enough research to determine if it is effective for any of them. It’s used to increase energy, stamina, mental capacity and strength.

The extract is considered an adaptogen so it helps the body adapt to and resist various stressors. It is also used to improve athletic performance, improve sexual function, reduce recovery time after workouts, to treat depression and address heart health issues such as high cholesterol and irregular heartbeat.

Some people use it to treat cancer, tuberculosis, and diabetes, or to prevent cold and flu as well as strengthen the immune system. It’s thought to work by helping protect the cells from damage, regulating heart beat, and improving one’s ability to learn and memorize.

It’s worth noting, however, that none of these effects have been studied in humans, and additional research is needed to confirm any health benefits. [5]

Arginine-Alphaketogluarate (A-AKG)

It is a natural chemical found in the body that is sometimes used to make medicine to treat:

  • Stomach and intestinal
  • Bacterial infections
  • Kidney disease
  • Liver problems
  • Cataracts
  • Recurring yeast infections
  • Improving the way kidney patients undergoing hemodialysis treatments process protein

People also use it to improve athletic performance. [6]

What Are The Possible Side Effects of High T?

Though Testofen studies found it to be safe, some people found the fenugreek caused gastrointestinal issues such as diarrhea and bloating, along with nasal congestion when taken in amounts larger than what is typically found in food.

Other side effects include coughing, wheezing, facial swelling, and allergic reactions in individuals who are hypersensitive to it. Because fenugreek may also lower the blood sugar levels which means that diabetics will need to closely monitor their levels to make sure it doesn’t interact with any medication causing blood glucose levels to become too low.

Because Testofen and other ingredients in High T will increase testosterone production overall, it can lead worsening male pattern baldness worse, per a study published in the Journal of the American Academy of Dermatology. [7]

If you increase testosterone beyond its normal range, it creates an imbalance in estrogen and other hormones. This imbalance can lead to gynecomastia, or an enlargement of breast tissue. Though it may go away on its own if you stop using a testosterone booster, it’s possible it will persist enough to require medication or surgery to solve the situation. Sperm production is often decreased as well. [8]

Increasing testosterone can also increase facial and body hair and cause further deepening of the voice. It can also be linked to behavioral changes, such as radical shifts in mood, attitude and behavior, often accompanied by increased aggression, irritability, and depression.

High T and Women: Is it Safe?

Women naturally have testosterone in their bodies, just like males have a small amount of estrogen, too.

The difference is women have much lower levels of testosterone. Increasing testosterone levels in women could result in the development of masculine characteristics such as increase in facial and body hair, deepening of the voice, and more aggressive or irritable behavior.

How Much Does High T Cost?

A 60 count bottle can be purchased on Amazon for $25.99. If you would prefer to buy the product in person, it is available at GNC and Walgreens, though prices may vary slightly depending on your geographical area. GNC has a 75 capsule bottle for $36.99.

What’s the Difference Between High T and High T Black?

Is There a Money Back Guarantee?

You cannot order High T supplements directly from the manufacturer’s website. Because of this, any money back guarantee would be subject to the terms of the merchant where you make your purchase.

The Bottom Line – Does High T Work?

Previous High T Review (Updated June 15, 2012):

High T: What You Should Know

High T Black is a testosterone booster that claims to boost libido as well. The ingredients include common libido boosters like tribulus and eurycoma longfolia, like in TestoStorm, but with a dose of caffeine. Most testosterone boosters don't include caffeine and we're unsure why this company chose to include a fat burner in the ingredient list. With 200 mg of caffeine, this supplement should only be taken in maximum quantities by bodybuilders used to taking stimulants. The proven effect on testosterone is limited as most testosterone boosters with tribulus and eurycoma longfolia do nothing more than increase libido so the user thinks testosterone is on the rise. For example, acetyl l-carnitine hcl, contained in Cyvita, is a unique ingredient not found in most supplements

List of Ingredients in High T


  • Vitamin E
  • Vitamin B6
  • Vitamin B12
  • Zinc
  • Razberi K
  • Caffeine Anhydrous
  • Trigonella Foenum-Graecum Extract
  • Rhodiola Rosea Extract
  • Eurycoma Longfolia Extract
  • Testofen Fenugreek Extract
  • Tribulus Terrestris
  • Arginine Alphaketoglutarate
  • L-Citrulline Malate
  • 3-Aminopropanoic Acid (Beta Alanine)

Product Features

Sometimes the ingredient list for a supplement like High T is useless if the product does not work in real life people. While the ingredient list is common and many other supplements use tribulus, eurycoma longfolia and arginine to boost testosterone, not all products have a good following and a plethora of positive reviews. Six Star Testosterone Booster can attest to that. We found this product for sale on GNC and the reviews are pretty phenomenal, but there could be a reason other than a testosterone boost for most of the reviews.

High T packs in 200 mg of caffeine. That caffeine is bound to boost energy and vitality on some level. So, all the reviews claiming this product gave the user a ton of energy so low testosterone must be the problem are useless. The increase in energy has nothing to do with testosterone levels and everything to do with that 200 mg of caffeine not commonly found in testosterone supplements.

The biggest complaint about the product was dosing and taste. You have to take four capsules per day. We like the high capsule dose because it allows the user to regulate caffeine intake. Each capsule contains 50 mg of caffeine, so sensitive dieters can take one and work up to the full dose as their body gets used to the caffeine. However, eventually even the 200 mg of caffeine will not give the user that boost in energy because the body will get used to the caffeine and expect more.

High T Advantages

  • A complete list of ingredients is found online.
  • May leave the user with more energy.

High T Disadvantages

  • No clinical proof the supplement works as claimed.


High T may help the user feel more energy, but there is no proof it will boost testosterone. Many companies simply lack proven studies for their products, just like M Drive. The company claims the user must diet and exercise regularly for the supplement to be effective. It also takes two months for optimal effects. Taking 200 mg of caffeine every day for two months will cause the user to become addicted to that caffeine level and if they stop taking that amount of caffeine daily they could suffer caffeine withdrawal. At 300 mg Troxyphen will have a user experience similar effects.

    i have one bottle but is already expired, on 07/2015 can i take even with 6 mounts expired?

    • Stephen (Editor)

      Luis, at the very least the pills may not have their intended potency after it’s expiration date. Also you run the risk of becoming ill by taking expired pills. If you want to boost your testosterone, you might want to try something more recent, like Pronabolin.

  • cycle to follow
    Jason (Verified User)

    Just wondering if there is a cycle to follow? Take it for a while then stop and start again. Stopped taking it for about a week now after a 8 week cycle, so I was just wondering. But I will say, that I’m in my forties and noticed quicker recovery after work outs while taking it. As well as increased energy throughout the day. Only taking 2 pills a day. So far, it’s been ok but recommend taking it with food. Found out, for myself, that taking the pills with a regular meal (usually a serving of cereal, yogurt and fruit) would offset the stomach ache, if you call it that, and indegestion.

  •  I recommend it to lifters
    Eric (Verified User)

    I am an avid lifter, not too crazy, but I work out every day. I take a medication that I think reduces my testosterone, so I was looking for a way to get my levels back up and tried High T. I have seen results after 1 week of use, but I think you have to work out with it in order for it to work at all. Some people say “no results,” but those people are probably not exercising. You can’t just take high t and not exercise and expect results. I have noticed a little growth since taking High T, (and its definitely there) and increased sex drive. I reccomend it to lifters who think they may be struggling with their testosterone levels.

  •  Product is not good for me
    terry (Verified User)

    I had good workouts but then I started having the side effect of blood in my urine. When I discontinued use my urine when back to normal after a couple of days. The vendor would do an exchange because they said it was not a GNC product.

  • So that whole thought of the caffiene being the reason for energy benefits doesn't add up?
    d (Verified User)

    I just started taking this product yesterday. From my research of many reviews people say this product gives them a lot of energy through the day. This post you have writtten implies that 200mg of caffiene is responsible for energy through the whole day. Well a cup of coffee is 95 to 100 mg of caffiene. And two cups of coffee definately won’t give you energy through the whole day. So that whole thought of the caffiene being the reason for energy benefits doesn’t add up.

  •  Loved the product.

    I have been using High T for a year.I am 64 and I had my doctor check my testerone blood leval and it s normal . The product has no side affects and my libido is like I was 30 again.I take only 2 capsuls a day.
