Ingredients Comparison

Alpha Jym Full Ingredients List

  • Fenugreek
  • Damiana Leaf Powder
  • Ashwagandha Root
  • Diindolylmethane 
  • Tongkat Ali Root Extract
  • Quercetin
  • Vegetable Cellulose
  • Magnesium
  • Silicon Dioxide 

Ingredients in Alpha Jym are a little different from the formulas found in most of the leading T-boosters, including TestoFuel. There are several notable ingredients for both good and bad reasons. 

The first ingredient worth mentioning is ashwagandha extract: one of the less common ingredients, but it is also one of the best. There are many scientifically-backed proven health benefits associated with this ancient root. In the men’s health supplement market, encouraging natural testosterone production is the primary function.

Another advantage of ashwagandha extract is reduced stress and anxiety. Both these things can play a part in diminished sexual and physical performance in men over 40. Avoiding this decline is one of the things that makes this an attractive product for more advanced men.

When it comes to sexual stimulants and aphrodisiacs, they don’t come much more powerful than damiana leaf powder. Although there is insufficient scientific evidence to back that up, it has been used worldwide for hundreds of years and is believed to work magic. It can help men regain confidence in the bedroom and the youthful energy to go with it. 

Finally, let’s discuss Diindolylmethane (DIM): a controversial part of the formula. Although technically a natural ingredient, it does not naturally occur in the human body in this state. What that means is that the effect can be a little unpredictable. 

It is a form of hormone regulator that can block estrogen (the female hormone) and increase testosterone, but it can also do the opposite. Too much estrogen in the male body can make it hard to keep up libido and sexual performance. To a man using Alpha Jym specifically to boost his T-levels above all else, this is concerning. 

One of the issues with the inclusion of DIM in a testosterone boosting supplement is the studies that link it with reduced sperm quality. 

There is a lot of conflicting information about Diindolylmethane and testosterone, so do thorough research before using Alpha Jym if this is a concern for you.

TestoFuel Full Ingredients List

  • D-Aspartic Acid
  • Panax/Red Ginseng
  • Fenugreek
  • Zinc
  • Magnesium
  • Oyster Extract
  • Vitamins K2/B6/D3
  • Silicon Dioxide
  • Vegetable Cellulose

TestoFuel is focused primarily on boosting strength and stamina, marketed towards men who want to get fit and bulk up. The choice of vitamins and other minor ingredients makes this clear.

Vitamin K2 is known to increase bone health, and Vitamin D3 to strengthen muscles. Together, they are a formidable combination for boosting stamina and increasing your workout game.

TestoFuel includes oyster extract. It is one of the best-known aphrodisiacs and a powerful libido-booster. The downside, however, is that anyone with a shellfish allergy cannot use this supplement. 

There is a lot of evidence to back up the many health benefits of magnesium– both mental and physical. One of these benefits is improved performance during exercise. Magnesium is essential for a healthy, strong body: it encourages muscle growth and speeds up recovery times. 

It can also help reduce symptoms of depression. Mental health plays a huge part in men’s health, and a healthy mind can help you keep control of your body. As one of the primary ingredients in TestoFuel, it helps keep you in top physical condition for a busy workout schedule.

What Formula Comes out on Top?

Each of these products targets a different market, so it is hard to pick an overall winner, although there are some concerns over the Alpha Jym formula.

The general physical and mental health aids that come with Alpha Jym are great for the over 40s, but the doubts about DIM and fertility could be off-putting for younger men who still want to conceive. There is also a lack of essential vitamins and minerals, which is a big downside to this product.

TestoFuel is undoubtedly the superior supplement for bodybuilding.

If gaining muscle and boosting stamina is your primary interest, TestoFuel is one of the best choices on the market and is favorable over Alpha Jym.

Safety and Potential Side Effects

Generally speaking, the side effects for both these supplements are minimal because they are made entirely of natural ingredients.

That being said, you should always check with your doctor before starting on any testo-booster, just to be safe. 

Some of the side-effects you may experience when using either of these products include:

  • Headaches
  • Upset stomach
  • Nausea (particularly when you first start taking the supplement)
  • Mild rashes

Alpha Jym seems to be more prone to spurring reactions. Additional side-effects associated with Alpha Jym (again, in rare circumstances) are:

  • Hives in sensitive skin
  • Minute lead exposure

Both brands include some ingredients that can be bad for your health if taken in excess, which is why it is essential to stick to the recommended dosage. TestoFuel recommends four caps per day, and Alpha Jym states six, taken three at a time. Avoid taking pills on an empty stomach and wash them down with water only. Some users report suffering from nausea or cramps if they broke this routine.

Customer Results

Alpha Jym

Increased energy and a higher sex drive are the two most common positive comments from Alpha Jym clients. Users say they felt a noticeable jump in their day-to-day stamina both in and out of the bedroom. Additionally, most men who have been using the supplement for a while say their mental health has also increased. They feel happier, more relaxed, and more motivated.

On the other hand, there are quite a few reports about suffering from headaches and rashes in the early stages of using Alpha Jym. Some previous users suggest starting with a half-dosage to let your body get used to the formula. 

Overall, Alpha Jym users say the product is great value for money and that the results were palpable after roughly one month of taking it. 


This is by far the stand-out product for the 25-35 age bracket. The glowing testimonials of body transformation and complete revitalization are plentiful. The bodybuilding community is vocally supportive of this supplement, which is a major endorsement in itself.

Men who had struggled to take their workout game to the next level report seeing a huge difference in what they can achieve. Improved stamina and strength and faster recovery times are some of the positive effects.  It is not, however, a replacement for eating healthily or working hard. The purpose of TestoFuel is to give already healthy men the final push to help take control of their bodies.

To reach the maximum potential of what this supplement can allow, you should be prepared to wait several months. Most users say they started noticing a difference after three weeks of sticking to the advised dosage and maintaining a steady workout regime.

Manufacturing and Brand

There is very little information about where Alpha Jym is manufactured. What is known is that it was created by Jim Stoppani, who is known for pre-workout supplements and routines.

TestoFuel is manufactured in the UK in an FDA-approved facility. Having this information available makes us lean towards TestoFuel as being slightly more trustworthy, despite the star power of Jim Stoppani for Alpha Jym.

Price and Value for Money

Alpha Jym is one of the cheapest supplements on the market per capsule, at roughly $30 for a one-month supply. There aren’t many discounts, but the low starting price is hard to compete with. Also, because some people choose to half the supplement for a while, the $30 bottle can end up lasting two months.

TestoFuel offers many great deals if you buy in bulk, but it is still one of the most expensive testo-boosters out there now. A one-month supply costs roughly $65 if bought alone, but you can get free bottles if you buy more than one. 

There is no doubt that Alpha gym is far more affordable, but value for money is dependent on what you hope to achieve. If bulking up is the goal, then TestoFuel has better value because it gives you better results.
