Alpha Jym is a test boosting supplement which forms part of the range created by Dr Jim Stoppani and is focused primarily on maintaining optimum testosterone levels for bodybuilders.

One reduction that we can confidently say Stopanni’s supplement will help limit, even before getting into specifics, is your bank balance. It retails on Bodybuilding.com and Amazon at very reasonable prices $29.99 for 180 capsules, 60 per bottle.

Alpha Jym declares it harnesses all natural ingredients, forming a five pronged approach to sustaining a peak hormonal balance;

  • Stimulating testosterone of course
  • Curbing estrogen production
  • Provide protection from oxidative damage to internal test producers
  • Increase the amount of free testosterone in the system available to be utilised
  • Cut down on testosterone wasted through secretion.

So far so good, but let’s see if those all-important ingredients have what it takes to get our testosterone as high as our expectations.


How Does Alpha Jym Work?

Alpha Jym gets another gold star straight away for using fully disclosed and quantified natural ingredients and resisting the use of proprietary blends.

A supplement prepared to show in detail exactly what makes it tick exudes a certain self-assurance. If proprietary blends are chemical hedge mazes, designed to confuse and frustrateclear and concise products like Alpha Jym are open top bus tours taking you round all their areas of interest in turn and fully explaining them.

You can take the full bus tour down in our detailed ingredients analysis, for the moment we can sum up how it works;

Ingredients Summary

  • Fenugreek regulates blood sugars and control insulin levels
  • Diindolylmethane for estrogen suppression
  • Aromatase inhibition with Damiana Leaf
  • Ashwagandha reduces the production of cortisol
  • Quercetin and Longjack for estrogen reduction

The Scores

Alpha Jym

There’s nothing truly ineffective here which goes in its favour, although if they were smart they would give away free condoms or a chastity belt or something with Alpha Jym because a lot of its main ingredients seem far more tailored towards boosting the libido. That said, sizable amounts of fenugreek and ashwagandha root do give Alpha Jym some legitimate testosterone boosting credentials, so it would be foolish to write it off completely.


There’s no getting away from it, in the testosterone supplement market this is inexpensive. Alpha Jym is about as cheap as you can get when it comes to boosters, without seriously beginning to question the quality of what you’re taking. It hardly matters that it’s sold exclusively in one place as it’s so reasonable to begin with. I didn’t give it full points because the price we saw was reduced from $60, if that starts to creep back up at any time it would put a different complexion on things.


Dr Jim Stoppani is a well-established name on the supplement circuit by now. He has a range of products produced under the company name Jym Supplement Science and quite the cult following amongst the fitness community. There have been no reports of scams connected to either man or brand.


There are plenty of glowing testimonials on the Bodybuilder.com website which is a real strength, but at the same time, paradoxically, something of a weakness.

Stoppani has a really devoted following and a lot of the testimonials seem to be praising him more than the actual product. It’s a gut feeling but I thought there might’ve been an element of the cult of personality going on.


Can’t fault JYM Supplement Science. Slick website, full discloser of where supplements are manufactured (USA) and no apparent history of customer service or marketing irregularities.

How Do I Take It?

Alpha Jym requires that you take 6 capsules in all, 3 in the morning and 3 at night. This is not ideal when compared to some supplements. Having said that, at least there’s enough here to provoke active changes and it’s still not as bad as certain testosterone boosters which should really be sold with a kitchen funnel.

Anything Missing from Alpha Jym?

It’s been a solid performance from Alpha Jym so far then. Good price, no proprietary blends, all-natural ingredients. All in all, a very respectable testosterone booster.

The kind of supplement you could take home to meet your dad… particularly if he had low testosterone. As with so many of these products however, where Alpha Jym begins to fall short is in the ingredients which are notable by their absence.

Zinc & Vitamin D Normally when a supplement is missing a beneficial component, no mention is made of it, presumably in the hope that we’ll forget it’s necessary. Oddly though, in the promotional material the lack of proven testosterone boosting elements zinc and vitamin D is openly referred to.

They don’t dispute zinc’s proficiency for releasing luteinizing hormones, they don’t doubt the solid link between vitamin D3 quantities and hormone levels; so why leave them out?

“Because you should get your vitamins and minerals separately.”

Errr… Oh I see. Get them yourself? The point of taking a combined supplement is that you don’t have to buy them all separately. It costs a lot more for a start doing it that way, when you are having to take 6 pills a day there should be room for important vitamins and minerals that also serve to boost test.

It’s aimed at the body building market, it would have been much improved with some genuine test boosting stars like D-Aspartic Acid or Mucuna Pruriens. Or some proven SHBG inhibitors like Boron.

Alpha Jym Ingredients – In Detail



Given top billing in Alpha Jym, Fenugreek is an incredibly potent libido enhancer never a bad thing but it also serves to regulate blood sugars in the body, reducing insulin resistance which can inhibit testosterone. It has been shown to deplete production of the sex binding hormone globulin and with these levels lowered; more testosterone is left flowing freely and is able to be used by the body.

Damiana Leaf

This is another strong aphrodisiac ingredient, but some believe it acts as an aromatase inhibitor. The aromatase enzyme’s job is to convert testosterone into estrogen, so the idea is an anti-aromatase will restrict this process allowing more testosterone to remain in the system. There doesn’t appear to be a lot of evidence out there to suggest that Damiana Leaf does this effectively however and what work has been done mainly relates to lab rats.


Diindolylmethane (DIM)

A similar story to Damiana Leaf in a lot of ways, this molecule found in vegetables like broccoli, has been credited with having anti-cancer qualities as well as being another effective aromatase inhibitor. Likewise with Damiana leaf though, more evidence is needed.


Ashwagandha Root Extract

Used for many years in Indian traditional medicine as a stress reliever, its effectiveness has survived the jump to western use. The stress hormone cortisol is among one of the worst things that can happen to your testosterone, as it serves to block production. Anything therefore that counters this is pretty invaluable. A study performed on infertile men found that a regular dose of Ashwagandha Root was found to boost testosterone by 40% in just three months. More work needs done on fertile subjects to see if results are similarly impressive, but it’s hard not to be encouraged by such effective results.

Tongkat Ali / Eurycoma Longfolia

Eurycoma Longfolia

Eurycoma Longifolia Root a.k.a Longjack, a.k.a Tongkat Ali

. The direct testosterone boosting qualities of this ingredient are yet to be firmly established, but there’s a sizable amount of clinical evidence relating to its pro-erectile and anti-estrogen uses.


Found in red onions and red grapes, Quercetin is great for releasing nitric oxide into the body which helps blood flow and counters any circulatory issues. Included here for an ability to modify estrogen activity in the body, it can also prevent testicular damage and thereby prevent the decline of testosterone levels.


Taken as a complete package Alpha Jym is perfectly acceptable; good value from a reputable source with seemingly nothing to hide, a few highly desirable ingredients and no completely ridiculous ones.

Where Alpha Jym starts to deviate from that track slightly is in the number of constituent parts dedicated more towards strengthening libido – eurycoma longifolia and damiana leaf for example, where it starts to slow down a bit is in elements that need more research like DIM and quercetin and where it runs out of steam altogether is what it has left out.

To claim that vitamins and minerals like zinc, vitamin D and boron have to be taken separately is frankly bizarre. Why not include them and raise the price a bit more?

You could do a lot worse, but if you are serious about test boosting supplements then there’s no point in buying Alpha Jym as you only have to buy another booster to fill in all the gaps it’s deliberately left out.
