Jim Stoppani – Alpha JYM Review


Jim Stoppani is a huge name in the fitness industry but his testosterone booster Alpha JYM leaves a lot to be desired with some highly questionable ingredients and a lack of vitamin and mineral support.

What we like about Alpha JYM

Recommended supplementation calls for 3 pills twice a day (6 pills total) which yields a strong supply of Ashwagandha (1,000 mg) and Longjack (200 mg).

Herbs: AshwagandhaLongjack

⇒ Fully Transparent

Alpha JYM is fully transparent with their product. You know exactly what you are getting as they do not hide anything behind a “proprietary blend”.

⇒ Good Quantity of Ingredients

While we may disagree with some of the ingredient choices in Alpha JYM, there is ample amounts of everything in it.

What we are 50/50 on

⇒ Bioflavonoid Quercetin 

Quercetin is a good nutrient with a wide range of health benefits and supplementing with quercetin in dihydrate form, is the most bioavailable form, which Alpha JYM uses so props to them for that.

While no human studies have been directly linked to a boost in testosterone, Quercetin appears to inhibit an enzyme called UGT2B17 which converts testosterone into a molecule known as testosterone glucuronide.

Testosterone glucuronide is excreted via the kidneys and your urine. So it would seem that supplementing with quercetin may help keep more of your testosterone in your system which is great.

We have not seen a human study yet where less than 500 mg of daily supplementation was used effectively and in most cases it was 1,000 – 2,000 mg. In order to get 500 mg of Quercetin you have to take the full 6 pills every day which is a lot of pills.

Overall, we feel it would be better to take quercetin as a standalone supplement more in the range of 1,000 mg daily.

What we don’t like

Alpha JYM Supplement Facts

⇒ Where Is It Made?

We don’t know where it’s manufactured or if it’s in an FDA or GMP certified facility which usually means it is not.

That’s always a little scary considering the supplement industry’s reputation for cutting corners.

Considering the large doses of Ashwagandha and Longjack are on the expensive side to manufacture, it is a valid concern.

⇒ No Vitamin or Mineral Support

Sure, you can take a good multivitamin to help cover your baseline needs but it is nice to have some additional support from the supplement you are buying.

There is also a lot of questions about both the effectiveness and quality of most multivitamins on the market. Personally, I want the vitamins and minerals which will best support my T levels to be in my testosterone boosting supplement.

⇒ A Lot of Pills

Taking 3 pills, twice everyday, is just a lot to keep up with.

Unproven Over-Hyped Ingredients

Fenugreek Extract – Used to treat menopausal symptoms, induce childbirth, and increase the supply of breast milk in lactating mothers.

Why is it in so many T-Boosters on the market today? Because of a patented extraction method called “Testofen” which used “in-house” studies to try and validate it as a miracle testosterone booster.

Interestingly, Nugenix which helped push Testofen into the limelight by running a series of extremely costly ads, doesn’t even use that extraction method in their own Ultimate Testosterone product, opting instead for regular Fenugreek Extract.

We have yet to find a non-sponsored study on either Fenugreek or Testofen showing any improvement in T levels but there are a lot of studies showing no increase.

Damiana Leaf Powder – There are two isolated compounds in damiana leaf, pinocembrin and acacetin, that may suppress aromatase activity, which is the body’s conversion of testosterone to estrogen. This is good for your testosterone.

However other compounds, apigenin 7-glucoside, Z-echinacin and oddly enough pinocembrin again, showed estrogenic activity. This is bad for your testosterone.

The jury is still out on how effective damiana is for a man’s testosterone levels but based on the evidence at hand, you shouldn’t expect to see any results from it.

For women, a lack of scientific evidence still prevails but anecdotal evidence abounds which kind of makes sense given the strange and fairly unique anti-estrogenic and estrogenic mix damiana appears to have.

⇒ Diindolylmethane (DIM) – There is a lot of hype around DIM but to date the human studies have varied greatly with little to no evidence supporting claims of a testosterone increase.

In fact, there has been evidence showing it may actually decrease testosterone in humans while in rats it has been shown to lead to histological degeneration of testicular tissues which is something you obviously don’t want.

Lastly, DIM is frequently used to treat postmenopausal women. While a nutrient can certainly have multiple benefits and can react differently in men than women, in this case it just leaves yet another question mark as to what JYM Supplement Science was thinking adding it to their T booster.


Overall we find Alpha JYM to be a big disappointment. Jim Stoppani, takes a lot of loose science to promote multiple ingredients in his product that have little to no proof behind the claims.
