The Key Differences

So here is the quick version and the key difference between Prime Male and TestoFuel. Read below for more in-depth info.

Prime Male

Great for men over 30 who either have low T or whose testosterone production is slowing down. This ingredients formula targets the creation of testosterone, helping your body keep up testosterone production at healthy levels.


TestoFuel Testosterone Booster

This is great for bodybuilders or men who are looking for serious muscle gains who already have healthy testosterone production (and usually who are under 30). This is because it promotes greater absorption of the testosterone your body is already producing. This means less testosterone goes to waste and you maximize efficiency giving you the benefit of more testosterone without the risks of taking testosterone production to unhealthy levels.

Prime Male vs TestoFuel

Before we get into the details of the two products, it’s important to note that what is the best choice for you will depend on you and your goals. For instance, Prime Male should be your go-to supplement if you’re looking to increase your libido and sexual performance in your silver years.

On the other hand, TestoFuel is your missing link if you’re looking to gain solid muscle mass while reducing belly fat. TestoFuel has low quantities of zinc and vitamin D3, K2, and B6—all of which are required to keep your testosterone levels upbeat. Too much of these elements, however, can cause nausea, stomach pain, and even low blood pressure.

The Fundamentals

Prime Male

Prime Male is a high-grade all-natural testosterone booster specifically aimed towards older men. That said, younger men can still benefit from it, which is why Prime Male is one of the top testosterone boosting dietary supplements available today.

 Prime Male makes the following claims:

  • Achieve higher energy levels
  • Gain greater libido
  • Reduce body fat
  • Focus better
  • Grow muscle mass

Your dosage is 1 capsule 4 times a day. Each box of Prime Male gives you 30 servings (120 capsules).


TestoFuel brands itself as the missing link in your pursuit of muscle growth. It claims to fill the missing link by supplying the nutrients that your body needs to produce more testosterone naturally.

TestoFuel claims that by consuming the supplement every day, you can:

  • Gain durable muscle growth
  • Build strength
  • Boost your libido
  • Reduce body fat
  • Stay upbeat

Your daily intake is four capsules, and you get 30 servings (120 capsules) per box. According to the manufacturer, anyone above 18 can use TestoFuel to gain and sustain muscle mass.

The Ingredients

Companies that make testosterone boosters know that many people who are interested in taking testosterone supplements are also interested in building muscle mass and increasing sex drive. They use this to market their supplements, and as a consumer, it can be all too easy to buy into it.

That’s why at its core, a supplement worth its hype is made with essential nutrients that can naturally increase your body’s testosterone production. A high-quality feature of both Prime Male and TestoFuel is that neither of the supplements contains any proprietary blends.

Patented blends can hide the number of ingredient doses, which makes them somewhat of a health risk. Prime Male has 12 ingredients, and TestoFuel has  nine,  including a massive amount of magnesium, oyster extract, and D-Aspartic acid to encourage anabolic muscle growth.

Both share many common ingredients, but the doses are what separates these two testosterone boosters apart from everything else in the market.

TestoFuel appears to have less dosage than PrimeMale when it comes to the following ingredients:  

IngredientPrime MaleTestoFuel
Vitamin D3      5000IU4000 IU
Vitamin K2      45mcg18 mcg
Vitamin B610 mg5 mg
Zinc20 mg10 mg

Still, TestoFuel’s formula carries more magnesium (200 mg) and D-Aspartic Acid (2300 mg) than Prime Male, which supports anabolic muscle building. On the other hand, Prime Male’s formula includes nettle root and luteolin that offers you sustained testicular health and halts testosterone decline as you grow old.

TestoFuel also carries fenugreek to power your most critical androgen hormone levels, while Prime Male has a decent amount of mucuna pruriens to keep you upbeat and motivated.

Let’s closely examine the ingredients that are present in both Prime Male and TestoFuel


If you work out regularly, there’s a decent chance that your body is not getting enough magnesium. Recent research indicates that the majority of athletes only consume about 70% of their recommended magnesium intake. (1) This vital mineral helps you recover from grueling workouts while elevating your testosterone levels as well as your sleep quality. (2)

Vitamin B6

Vitamin B6 plays a significant role in your overall well-being. A regular intake of B6 keeps your eyes, skin, liver, and hair healthy while boosting your testosterone levels by energizing other androgens. Research suggests that a B6 deficiency can cause your testosterone levels to drop alarmingly. (3) Alternatively, a body that maintains rich levels of B6 can freeze its estrogen levels by 30%, which gives the testosterone enough breathing space. (4)

Vitamin K2

Vitamin K2 is an unsung hero of testosterone boosters. Studies reveal that K2 works in harmony with vitamin D3 to force your testes to release more testosterone. (5) In fact, the latest research indicates that supplementing K2 for only 35 days increases the circulation of your testosterone levels by 70%.(6)


A diet carrying healthy doses of zinc fires up your testosterone levels while significantly decreases Aromatization – the mechanism that rapidly converts testosterone into estrogen. (7) A body high on estrogen risks fatigue, weight increase, blood clots, and even a stroke.

D-Aspartic Acid (DAA)

D-AA plays a pivotal role in boosting the portion of your brain that governs hormone release.  A study revealed that supplementing D-AA to an individual for three months can raise his testosterone levels by 30-60% while bulking his sperm count by 60-100%.(8)


Chinese are using ginseng to treat many physical ailments for thousands of years. Today, it’s used to regularize erectile dysfunction and increase your sexual performance. (9) Ginseng also improves your cognitive ability, strengthens your immune system, and keeps your mood upbeat.

Ingredients Specific To PrimeMale


BioPerine is added to the formula to ensure that the rest of the Prime Male’s testosterone-boosting ingredients are functioning smoothly. (10)

BioPerine is also called “bioenhancement,” because of its power to extract more out of the nutrients that your body consumes.


Boron is an essential mineral for a healthy body because it makes the body release more testosterone. The mineral also helps your bone growth, in addition to regulating your sex hormones. (11)


Luteolin works to restrict estrogen development in the body, which in turn allows your testosterone levels to thrive. A body high in estrogen is highly vulnerable to an increased body  fat percentage, emotional instability, and depression. (12)

Mucuna Pruriens Extract

This ingredient helps your brain make more dopamine, which is a critical neurotransmitter for your productivity and motivation.

Nettle Root

Nettle Root helps your body slow down the transformation of testosterone into estrogen by acting as an aromatase inhibitor, which also helps older men with enlarged prostate reduce their size.

Ingredients Specific To TestoFuel


Fenugreek is loaded with selenium, magnesium, and zinc and can slow down your SHBG (sex hormone-binding globulin). Research reveals that regular consumption of fenugreek can significantly increase your hormone levels. (13)

Vitamin D

Vitamin D is a nutrient that bolsters your male hormones. Your body generates vitamin D when it’s exposed to the sun. However, it is not often enough, especially if your region doesn’t get much sun. According to a Journal of Science and Medicine in Sport study, a 4,000 IU dosage of vitamin D can help athletes gain muscle mass without any side effects. (14)

Oyster Extract

Oysters are the poster child of libido-boosting foods because they are rich in zinc.

Many studies have concluded that oyster extract helps your testosterone receptors stay functional while also acting as an aromatase inhibitor. This results in reduced belly fat. (15)

Other ingredients added include:

  • Gelatin
  • Iron oxide
  • Titanium dioxide
  • Azorubine

Potential Side Effects

Prime Male

Prime Male will not cause you any side effects because it’s made with an all-natural formula without any proprietary blend. Its only blip is the presence of zinc and nettle root, which can cause an upset belly if consumed on an empty stomach.


Much like Prime Male, TestoFuel is made with organic ingredients without any synthetic testosterone added to the formula. The dosages of all the ingredients are also sufficiently within a safe range. Though the amount of D-Aspartic acid is relatively high, it doesn’t carry any side effects.

That’s been said, if you consume too much TestoFuel, you may feel the following symptoms:

  • Nausea
  • Stomach pain
  • Insomnia
  • Headaches
  • Low blood pressure

It’s always a good idea to consult your physician before consuming TestoFuel, particularly if you have a long-term health problem.
