What You Need To Know About Testrovax

Testrovax is a supplement that is supposed to almost double your testosterone levels in just 12 days. However there is no evidence that it will work this way and side effects could be very unpredictable. Testrovax comes from Novex Biotech a Utah-based supplements company who have past form in claiming other people’s scientific results as their own. One of the ingredients in Testrovax called (D)-Asparaginic Acid has undergone testing but although this is contained in the formula, this does not prove that Testrovax will work as the advertising describes.

What Are The Side Effects Of Testrovax?

Side effects are likely and may be unpredictable. The product warns you that this supplement may increase aggression, overconfidence, and sexual arousal. It also warns of sleeplessness, tremors, dizziness, nervousness, headache and heart palpitations. Other side effects may include, itching, facial flushing, vomiting, nausea, stomach upset, diarrhoea, low potassium levels, weakness or fatigue.

How Much Does Testrovax Cost?

Testrovax is expensive. If you buy direct from the Novex Biotech website, it costs $69.99 for 90 capsules (30 servings or 1 month’s supply). It is on sale from GNC for $62.99 for 90 capsules. You can buy Testrovax via Amazon USA for $47.95 making it the best deal.

Our Verdict On Testrovax

We are not very impressed with Testrovax. The product makes some wild unsubstantiated claims in the advertising about how this supplement will increase your testosterone levels by 43% but it does not back up the claims with any evidence. In the course of our research we did find out that one of the ingredients (D)-Asparaginic Acid does have a strong but temporary effect on T levels but this should have been explained more fully to customers. The fact that it hasn’t led us to believe that ingredient quantities do not conform to this testing.

In addition we are very concerned about the other ingredients. With 13 herbal components many totally unrelated to testosterone production, side effects are likely to be a real problem. The product information warns us about some of these but in our opinion, they are only scratching the surface. We would not advise anyone to take this supplement. It is unproven, expensive and potentially dangerous so why on earth would you bother?

Testrovax Review

Testrovax is a testosterone-boosting supplement. It is not an anabolic steroid – a synthetic testosterone often taken illegally to boost athletic performance and build muscle. Instead it contains ingredients that the makers say will help your body manufacture more of its own testosterone naturally and draw on its natural testosterone reserves.

According to the advertising, a clinical trial has shown that Testrovax will cause a whopping 42% increase in testosterone levels after just 12 days of use. It seems a lot. If this supplement really does work in this way, it could have real implications for athletic performance. The product information does not say whether taking Testrovax is allowed in sport or whether using it will get you disqualified.

Testrovax Facts

  • Each bottle contains 90 capsules.
  • No proof that this supplement will work as described.
  • Comes from Novex Biotech a Utah-based supplements company.

So what do the Testrovax capsules contain? Aside from B vitamins it contains a proprietary blend called Testothrione in a hefty serving of 2.70g per serving which comprises of herbal ingredients in unknown quantities. The key ingredient is (D)-Asparaginic Acid. This amino acid is a form of aspartic acid which is often used as a temporary testosterone booster for either athletes or infertile men. Although it requires further clinical testing it looks promising.

Other ingredients include grape extract, fenugreek and revesterol all known for health benefits. It contains Damiana leaf – often an ingredient in legal highs, Withania Somnifera, liquorice root and red clover powder.

How to Take Testrovax

Take 3 tablets daily with breakfast.

There are 13 different ingredients in total so effects of this mix of herbal ingredients look like they may be unpredictable. According to a clinical test quoted in the advertising, this blend caused on average an increase of 42% of testosterone levels in the volunteer group after 12 days of use. We will look into this clinical test and the ingredients later in the review.

Testrovax Concerns:

  • Side effects could be very unpredictable.
  • The clinical testing is not explained. What else is this company not telling us?
  • Expensive. Could be a waste of money.

Novex Biotech is a supplements company based in Salt Lake City, Utah – an area of the USA known as the centre of supplements. We have covered Novex Biotech supplements before including Oxydrene Elite, a supplement that is supposed to increase VO2. Worryingly the claims for Oxydrene Elite were based on a probably exaggerated clinical trial carried out by another company.

What Does Testrovax Claim To Do?

According to the advertising, Testrovax is a “clinically tested functional testosterone-boosting compound”.

Healthy testosterone is described as causing:

  • Muscle Mass Growth
  • Increased Energy
  • Intensified Libido

Most of the advertising for Testrovax revolves around the clinical test.

A group of 43 men aged 27–37 years were divided into two groups: 1) the active Testosterone Booster compound group and 2) an indistinguishable placebo group. Results showed that serum testosterone levels in the active group were significantly increased compared to those of the placebo group over the course of the study, wherein the active Testosterone Booster compound led to a 42% increase in testosterone after 12 days of use. Interestingly, 3 days after the suspension of treatment, testosterone was still increased 1.22 fold compared to baseline in the treatment group, showing a lasting effect.

This sounds impressive but when looked into this and could find no record anywhere of this precise test. However we found a very small test for (D)-Asparaginic Acid that was favourable and took place over 12 days. This does not prove that Testrovax which contains a blend of ingredients in unknown quantities will work in the way described.

Does Testrovax Work?

It will not work as described but it may do something. (D)-Asparaginic Acid may help increase testosterone temporarily but the evidence for Testrovax looks flimsy. We are not provided with any of the ingredient details so there is no way of knowing whether this one ingredient conforms to the single clinical trial.

There is no real evidence that the other ingredients will increase testosterone at all. Some increase blood flow so are occasionally taken for erectile dysfunction but this is not the same as enhanced testosterone.

The bottom line is that this supplement will not increase your testosterone levels by 43% after just 12 days.

What Are The Ingredients of Testrovax?

The ingredients contained in Testothrione (Novex Biotech’s own brand) are under a proprietary blend so we cannot provide a full ingredients breakdown and only the vitamin content is provided.

Serving size is equal to 3 capsules.

  • Vitamin B6 (10 mg): The body needs B6 for more than 100 reactions required by the metabolism so is crucial for health and it is present in many foods including poultry, offal and fruit. The RDA is only 1.7mg but 10.00mg falls in the tolerable upper limit although can cause side effects.
  • Folic Acid (400 mcg): B vitamin, which is necessary for the proper development of the human body.
  • Vitamin B12 (10 mcg): Very important vitamin which is crucial for health. Many people are deficient in B12 and it can lead to a range of symptoms including fatigue. You can visit your doctor for a simple blood test to check this out for you.

Testothrione Proprietary Blend (2.7 g)

  • Schizonepeta Powder: Plant extract that may have medical uses including as a treatment for heavy menstrual periods and eczema. Does not seem relevant to this supplement.
  • (D)-Asparaginic Acid: This is one form of the amino acid aspartic acid and is often used as a testosterone booster by athletes. The effect is temporary but it can cause the body to release stored testosterone so is sometimes used as a fertility treatment. Testosterone will return to normal levels following taking. The standard dose for D-aspartic acid is between 2,000 – 3,000 mg. Does this supplement contain an effective serving size? This information is not disclosed.
  • Fenugreek Extract: An Indian culinary spice with potential health benefits. In Arab countries it is used as an aphrodisiac.
  • L-2-Amino-5-Guanidinopentanoic Acid HCl: Better known as the Arginine, this amino acid may have positive heart benefits because it seems to improve blood flow. It may do the same for erectile dysfunction for the same reason. Arginine is manufactured in the body but is sometimes taken as a supplement.
  • Resveratrol Extract: Resveratrol is a molecule present in natural substances such as red grape skins and not so appealingly as here where it is derived from Japanese knotweed (Polygonum cuspidatum). Resveratrol acts as an antioxidant and may help heart health and the immune system.
  • Grape Extract: Contains Resveratrol
  • Rhodiola Rosea Powder: Rhodiola Rosea is a plant that works in a similar way to Ginseng because it is a natural Adaptogen which means that it causes general feelings of well-being and is often taken as a supplement in its own right. According to animal testing, it may reduce fatigue and feelings of depression.
  • Liquorice Powder: Liquorice root is actually quite dangerous and will cause a range of side effects if consumed to excess. Amounts here are unknown. Although it may be useful some medical conditions, it lacks evidence and safety is of concern. It does not seem relevant to increased testosterone production.
  • Red Clover Powder: Red clover contains plant hormones that are similar to the female hormone oestrogen and is sometimes taken by women to ease symptoms of the menopause. This seems to be totally the wrong ingredient to include in a supplement that claims to increase male hormone testosterone.
  • Damiana Extract: Often used in legal highs and aphrodisiacs, Damiana is a natural shrub that grows in Mexico and hot places like Texas. It affects the central nervous system and can be dangerous in high amounts.
  • Withania Somnifera Powder: Also known as Ashwaganda a medicinal plant with a wide range of purposes. It is used as an adaptogen – a general pick me up or tonic and it may lower blood pressure and has a calming effect. Some evidence suggests it may help increase muscle mass if combined with training.
  • Taurine: Taurine is present in the human body where it is the major constituent of bile. It is an important acid, which has many biological roles. Early clinical research suggested that taurine improved mental performance. More recently, this claim has been disputed and more evidence is needed to prove it Ingredient in Red Bull.

Great product that helps your body boost your testosterone level as you age. I definitely recommend it! It gives you a great boost to your workout and has helped me a lot!

Solid product. Saw some signs of increased testosterone and gains at the gym.

There are only a couple of reviews posted on Amazon USA.

This stuff worked for me. Definitely noticed in my workouts. Not a huge difference but definitely felt better and stronger. Worked great for the libido but also made me a lot more aggro and kicked my anxiety up a bit. But to be clear I have anxiety anyways. I’m not gonna take it again because I don’t like feeling aggro. If you don’t mind that I would definitely recommend this product, it does what it says it does.

A little energy boost, no considerable gain in any other regards.
