Summary: Alpha JYM is a best-selling testosterone booster on I have not personally used it, but my review is largely based on an analysis of each one of its ingredients. Alpha JYM contains ashwagandha and tongkat ali. These are two of my favorite test-boosting ingredients because they're proven to have a positive interaction with testosterone. 

Verdict: Recommended. 


The fact that you're reading this right now means that your testosterone levels are not where they should be. If this is the case, its important for you to know that the endocrine system is way to complex to be fixed with a simple pill. Also keep in mind that Alpha JYM is a herbal supplement. It doesn't give your body testosterone, it only propels the natural process of T-production. 

Before looking towards supplementation, you have to look at your decisions regarding nutrition, exercise, sleep, and lifestyle. Once you have aligned your diet and lifestyle with getting leaner and building muscle, that's what will push your natural T production into overdrive.  Supplements should only be used for what they're made: 

To supplement your diet and lifestyle. They should never be relied upon as the sole means towards getting your results. 

But to answer the question: 

Yes, Alpha JYM contains some ingredients that are proven to increase testosterone. 


Regardless of what you've read about Alpha JYM online, my review reveals the unbiased truth. My conclusions about this supplement are based on peer-reviewed literature. Below, I've provided an overview of each one of Alpha JYM's ingredients and have cited a bunch of studies to back up their effectiveness/ineffectiveness.  

My aim with review is to provide you with the information to help you make an informed decision before purchase. ​

Alpha JYM Ingredients: 4/5

Alpha JYM contains no proprietary blends and the ingredients are listed out as is. 

Alpha JYM Ingredients


​Trigonella foenum-graecum, aka Fenugreek, is a herb from India that has traditionally been used as an aphrodisiac.

Although Fenugreek is a common ingredient in many best-selling testosterone boosters, the science refutes its ability to have any significant impact on T. Here's a look at the 3 human trials:

  • 500mg of Fenugreek supplementation in resistance-trained men was only enough to increase their bioavailable testosterone levels ​by 12.26% after 8 weeks of use (1).
  • 600mg of Fenugreek supplementation in healthy men (without ED) for 6 weeks improved their physiological aspects of libido without any impact on testosterone (2). 
  • 500mg of fenugreek supplementation in resistance-trained men had no impact on testosterone levels after 8 weeks of use. They did, however, experience a 9.42% decrease in DHT levels compared to placebo (3). 

The above are the only 3 human trials that have been performed with Fenugreek and its interaction with testosterone. For the most part, we can conclude that its impact on testosterone is negligible. Even in the first study, the subjects' levels increased by a mere 12%. This is nowhere near enough to experience any differences in energy, muscle-building, or quality of life. 

In the third study, subjects' experienced a 9.42% decrease in DHT levels. DHT is an androgen that is derived from testosterone. Basically everywhere in the body - except muscle tissue - the androgenic effect is carried out by DHT. It's DHT, and not testosterone, that exerts its influence on our brain, skin, and prostate. So lower DHT actually goes completely against the results we're after. 

The fact that Fenugreek is the first ingredient listed out on Alpha JYM really is a let down. Although supplementing with it may impact libido, the effect on testosterone levels will be next to nothing. 


Damiana (leaf)

Damiana is a supplement derived from the dried leaves of the Turnera Diffusa plant. In Central America, it has traditionally been brewed as a tea for use as an aphrodisiac. 

The evidence on Damiana is limited. There haven't been many studies performed with it, and even the ones that have do not involve humans. A couple of rat studies (4, 5) have shown aphrodisiac effects, but the rats were "sexually sluggish" to begin with. A test-tube study (6) shows Damiana to have aromatase inhibiting effects, but in no way can we conclude that the same effect will take place in humans as well. 

This is the first time I've seen this ingredient in a testosterone supplement. Damiana is not a proven testosterone booster. 


Diindolylmethane (DIM)

​Broccoli, kale, and cauliflower are the most prominent sources of DIM. Their DIM content is the primary reason this family of vegetables is considered healthy.

​The primary function of DIM is the regulation of estrogen metabolism. Its two roles include: 

  • Inhibiting aromatase, which prevents the conversion of testosterone into estrogen (7).
  • Converting stronger estrogen molecules into the less potent kind (8), thus reducing the overall effect of estrogen on the body. 

DIM also has powerful anti-cancer effects on the body. 

The fact that Alpha JYM includes 250mg of DIM is the first plus point of this supplement. ​


Ashwagandha Root Extract

​Ashwagandha, aka withania somifera, is a herb from India that is used to treat a wide variety of conditions. Ashwagandha literally means "smell of horse," inferring that it gives you the strength of a stallion. Also, the herb has traditionally been prescribed to strengthen the immune system after illness. 

Ashwagandha is an adaptogen, meaning that it helps your body better manage the physical and chemical effects of stress.

Cortisol is the hormone your body releases when its stressed. It is derived from the same building block as testosterone, i.e. higher cortisol = lower testosterone. Supplementing with ashwagandha can help decrease your cortisol response and synthesize more testosterone as a result. 

Let's take a quick look at the research: 

  • 300mg of Ashwagandha supplementation in chronically stressed men was able to lower cortisol levels by 27.9% in 60 days (9). 
  • 5g of ashwagandha supplementation in infertile men was able to significantly increase testosterone levels (10-22%) and lower cortisol levels (36-48%) after 3 months of use (10). 
  • 600mg of ashwagandha supplementation in healthy men (on a resistance-training program) significantly increased their T-levels, muscle mass, and strength (11). 

As you can see, Ashwagandha is a proven ingredient. Even though the first two studies used subjects that were either chronically stressed or had very low testosterone levels to begin with, the positive interaction with testosterone is clearly evident. 

Now, you may not experience such drastic effects, but even in healthy men supplementing with the herb, significant increases in testosterone, muscle mass, and strength were observed. ​

Alpha JYM contains 500mg of Ashwagandha extract which really is a plus point. This herb is amongst my favorite test-boosting ingredients. 


Eurycoma Longifolia Root Extract

​Tongkat Ali, aka Eurycoma Longifolia, is another one of my favorite ingredients to see in testosterone supplements. It has traditionally been used as an aphrodisiac and there is plenty of evidence supporting its testosterone boosting abilities as well: 

  • 200mg/day of Tongkat Ali supplementation for 4 weeks in men with moderate stress​ was able to increase testosterone levels by 37% compared to placebo (12). 
  • 200mg/day of Tongkat Ali supplementation in men with hypogonadism (low T) was able to increase testosterone levels by 46% in as little as 4 weeks (13). 

An important point to note is that the studies cited above used subjects that were either stressed or had very low testosterone levels to begin with. This means that they had a wider room for improvement compared, to say, someone who is otherwise healthy. So although supplementing with Tongkat Ali may not have you experiencing 46% higher T after 4 weeks, the positive interaction that it has with testosterone is clearly evident. 

Alpha JYM contains 100mg of Tongkat Ali. Even though the studies cited above used 200mg doses, the fact that Alpha JYM even contains it is another plus point. Whether the impact will be notable, though, is questionable. 



Quercetin is a compound found in fruits and vegetables, but most commonly in apples and onions. It has been shown to have anti-oxidant, anti-cancer, and anti-artherogenic qualities. 

As for the research performed with quercetin, there's been a lot of test-tube and rat studies, but human studies are limited. 

In one study, researchers fed rats onion juice at 4g/kg of bodyweight for 20 days, after which the rats experienced significantly higher testosterone levels (14). 

Due to a lack of human research, quercetin is only a potential testosterone booster.

For this portion of the review let's see how Alpha JYM stacks up against some other best-selling testosterone supplements. 

Alpha JYM vs TestoFuel

TestoFuel contains a proven vitamin and mineral formula. Vitamin D, vitamin K, zinc, and magnesium are all micronutrients that are proven to have a positive interaction with testosterone. 

The primary ingredient in TestoFuel is D-Aspartic Acid. I'm not a fan of D-AA because human trials have shown no long lasting impact on testosterone. It seems to increase T within the 2 week time span, but past that mark the effect is negligible. 

Although TestoFuel packs in a bunch of proven nutrients, I'd recommend Alpha JYM over it because of the Tongkat Ali and Ashwagandha. ​

Winner: Alpha JYM

Alpha JYM vs Test Freak

Test Freak is a supplement manufactured by PharmaFreak. It contains a ZMA formula (zinc, magnesium, vitamin B6) along with a bunch of proprietary blends. 

The primary ingredients in Test Freak are fenugreek and tribulus, both of which are proven not to have any significant interaction with testosterone. 

Test Freak also contains a DHT support blend, which is meant to inhibit DHT production in your body. Many unaware men think that DHT is "bad" since it's a cause of baldness. Although this is true, the benefits of DHT far outweigh the drawbacks. 

I would definitely recommend Alpha JYM over Test Freak.​

Winner: Alpha JYM

Alpha JYM vs Nugenix

Nugenix is a best-selling supplement on It is contains a proprietary blend comprised of L-Citrulline, fenugreek, and tribulus. 

​You already know the case with tribulus and fenugreek, but L-Citrulline is an ingredient that I quite like. It is a proven nitric oxide booster and is added to many pre-workout supplements to enhance blood flow. 

Even still, I never recommend supplements containing proprietary blends and Alpha JYM's ingredient profile is far superior anyway. 

Winner: Alpha JYM

Alpha JYM vs Animal Stak

Animal Stak is another best-selling test booster on It is manufactured by Universal nutrition. 

Animal Stak contains a bunch proprietary blends, but the primary ingredient seems to be Tribulus. 

Ingredients are usually listed out in terms of composition, and the fact that tribulus is first on the list really is a let down. Triblus has been shown in countless studies to have no impact on body composition, strength, or testosterone levels. Yet, it continues to be the primary ingredient in so many testosterone supplements. 

Alpha JYM definitely comes out on top in this case as well. 

Winner: Alpha JYM
