These four common ingredients are scientifically proven to boost testosterone and provide other benefits too. Let’s take a look at each of them: 

Common Ingredients 

1. Vitamin B6 

study published in Science Direct linked Vitamin B6 deficiency with low levels of testosterone. Vitamin B6 plays an important role in synthesizing testosterone. Another independent study published in PubMed associated low levels of Vitamin B6 with symptoms of depression. The study suggests that adequate levels of Vitamin B6 can maintain and improve overall mood and happiness

2. Magnesium 

The inclusion of magnesium is a real plus point. Magnesium improves the production of free testosterone and boosts muscle strength. According to research published on SpringerLink, it related increased magnesium supplementation with higher values of testosterone. A separate study published in PMC linked magnesium intake with increased gains in muscle strength. 

3. Zinc 

Men with zinc deficiency are known to possess low testosterone levels. A study published in the National Library of Medicine connected zinc deficiency with low levels of testosterone. Additionally, zinc also improves sleep quality and immunity, two vital cogs that are essential to maintaining fitness levels. Two separate research articles (Study 1Study 2) published on PubMed strongly associate better sleep and immunity with zinc intake. 

4. Fenugreek 

Fenugreek seeds are a commonplace ingredient in food, especially in Indian dishes. And they have also proved to boost testosterone and reduce body fat. Looking at the results of research published in the International Journal of Sports Nutrition and Exercise Metabolism (IJSNEM), subjects who ingested the fenugreek showed significant changes in body fat percentage and total testosterone levels. 

Unique Ingredients 

Test Freak 

The unique ingredients in Test Freak are all plant based ingredients. A few of them, like saw palmetto and resveratrol, are proven to help in enhancing exercise and boosting testosterone levels. 

1. Tribulus 

A research journal published in Taylor & Francis Online gives evidence that tribulus is ineffective for increasing testosterone levels. There is no other evidence available to show otherwise. 

2. Saw Palmetto 

Research shows Saw Palmetto extract has no effect in raising testosterone levels. The study published in IJSNEM gave evidence that Saw Palmetto has no effect on T-levels at all. However, it seems to help in treating an enlarged prostate according to a study seen on DovePress. 

3. Stinging Nettle 

This is another herbal extract. Stinging Nettle is said to have various benefits. One of the benefits includes its effectiveness against treating an enlarged prostate. However no studies show any indication of it helping to boost T-levels. 

4. Resveratrol 

Two studies published in The Journal of Physiology and SpringerLink indicate increased endurance and boost in T-levels induced by resveratrol. 

5. Li Meng/Lemon 

The lemon used in Test Freak does not have any scientific evidence to prove its use against boosting testosterone levels. It is said the lemon helps in weight loss, but this is mostly anecdotal evidence rather than a research based one. 

6. Roman Chamomile 

Chamomile helps with sleep according to a study published in the National Library of Medicine. No other evidence is available to show any effect on muscle building or testosterone levels. 


TestoFuel has five unique ingredients (one less than Test Freak) which are packed with T-level boosting goodness. 

1. Vitamin D3 

According to a study published on PubMed Central, subjects with Vitamin D3 deficiency showed lower levels of testosterone. This shows that adequate levels of Vitamin D3 are required to maintain testosterone levels. 

2. Vitamin K2 

Though Vitamin K2 does not have any effect on testosterone levels, it significantly improves heart and bone health. Separate studies published on PubMed proves this. 

3. D-Aspartic Acid 

D-Aspartic Acid is a powerful ingredient that helps stimulate testosterone production in adults with low T-levels. Research published in BioMed Central clearly indicates the role it plays in affecting T-levels. 

4. Asian Red Panax Ginseng 

An important ingredient in traditional Chinese medicine, Panax Ginseng is known to boost immunity and increase physical activity while reducing fatigue. Both studies (Study 1Study 2) on this have been published on PubMed, thus proving its effectiveness. 

5. Oyster Extract 

Oyster extract is a super ingredient that has several useful vitamins and minerals. Derived from the meat of oysters, it includes testosterone boosting minerals like magnesium and zinc, and Vitamin B12 which our body cannot produce but needs. The US Department of Agriculture has a full list of nutrients included in oysters. 

Our Pick

TestoFuel has the superior ingredients formula and a longer track record of success. It's our pick for those looking to build muscle, increase strength or boost energy levels. 

Safety and Potential Side Effects 

Both products are quite safe to use. Each ingredient is natural and beneficial to our bodies. Unless you’re allergic to any particular ingredient, both products shouldn’t give you any problems. In case you’re taking any medication, consult your doctor before taking the supplements. 

In rare cases, herbal extracts in both products may cause headache, dizziness and nausea. 

A major caveat for Test Freak. Their official website lists a “US Only” product which includes 3 proprietary blends. Proprietary blends are made up of small doses of different ingredients.  

While proprietary blends are beneficial, the major concern lies in the fact that you don’t know what is the dosage of each ingredient. Studies have shown that proprietary blends have varying amounts of each ingredient. This raises the question of whether there is an overdose of any ingredient or not. This lack of knowledge could prove harmful for you. 

Overall, TestoFuel comes out on top when it comes to safety since Test Freak includes proprietary blends in their product. 

Customer Results 

Both products have reviews on both ends of the spectrum. 

On one hand TestoFuel has had a lot of happy customers stating that they’ve gained muscle and improved energy levels. Many, however, claim that there is no neither a positive nor negative effect on their bodies. 

Test Freak also has had many positive reviews. But at the same time customers have reported side effects like body odour and sickness. Just like TestoFuel, some customers reported no changes at all. 

Manufacturing & Brand 

TestoFuel and Test Freak are reputed companies based out of the UK and Canada respectively. 

TestoFuel is manufactured by Roar Ambition Ltd (the same company that makes Prime Male) which was incorporated in 2014. It also carries out production in the US, at an FDA approved facility. 

Test Freak is manufactured by PharmaFreak and was founded in 2008 by the fitness freak duo of Alex Savva and Don Gauvreau. Not much else is known about the company’s whereabouts although it is a legit business. 

Price & Value for Money 

TestoFuel has different price models. A single box costs $59. You also have an option to buy 12 boxes at $495.60. They also have a buy 3, get 2 free and buy 2, get 1 free option at $177 and $118 respectively. 

Test Freak has only one option which is priced lower. According to the official website, one box would cost you $47.93. 

Test Freak trumps TestoFuel when it comes to money. But TestoFuel is still the better option despite the higher price, since it has the more effective and safer ingredients.

Test Freak vs TestoFuel – Final Thoughts 

At the end of all things, we can safely say that both TestoFuel and Test Freak stack up well. However, there is a catch with Test Freak. 

TestoFuel is packed with all natural ingredients that are bound to help you boost your testosterone levels, help you build muscle mass, and improve your overall confidence and well-being. 

The main ingredients to look out for are zinc, magnesium, Vitamin B6, D-Aspartic Acid and Oyster extracts. Moreover, TestoFuel is manufactured safely in an FDA-approved facility. 

Test Freak also includes major testosterone boosting ingredients like zinc, magnesium and Vitamin B6. But, we raise a huge red flag with the proprietary blends. 

The US only product includes three proprietary blends with potentially imbalanced dosages that could prove harmful. Also some ingredients in Test Freak seem to have no proven effects on T-levels or on muscle building. 

Ultimately, if you’re looking to raise and maintain your testosterone levels, elevate confidence levels, and enhance muscle strength, TestoFuel looks to be the better and safer product
