Product Overview


Alpha JYM















Testosterone is truly the alpha hormone! It’s what separates the men from the boys. Healthy testosterone levels are critical for guys who want to build muscle mass, boost strength, drop body fat, and gain a competitive edge.*

At 50+ years old, my own testosterone has certainly dropped from the levels I had as a younger man. I formulated Alpha JYM for healthy adult males who want a real, fully loaded natural testosterone support product.*



Alpha JYM contains six ingredients, provided in effective amounts, shown in research to naturally optimize healthy testosterone levels.* The six ingredients are: fenugreek seed extract, ashwagandha root extract, damiana leaf powder, diindolymethane (DIM), eurycoma longifolia extract, and quercetin dihydrate:

Alpha JYM provides a total of 2,100 mg (2.1 grams) of active ingredients per serving. When taken twice per day as recommended, it delivers a total of 4,200 mg (4.2 grams) of active testosterone-optimizing ingredients.* Alpha JYM is what I use to help optimize my body’s natural testosterone levels to support performance in the gym, great physique results, and overall health.*



The ingredients in Alpha JYM work to optimize testosterone levels through five separate mechanisms.*

1) Optimization of the Body’s Own Production of Testosterone*
Alpha JYM helps healthy males maximize their natural testosterone production.* In healthy males, ingredients in Alpha JYM may help promote the release of luteinizing hormone (LH) from the pituitary gland.* LH travels through the bloodstream to the testicles, where it helps promote testosterone production.* The end result is promoting healthy testosterone levels.*

2) Supporting a Healthy Balance Between Estrogen and Testosterone*
Alpha JYM supports healthy levels of enzymes that normally convert testosterone into estrogen.* Estrogen is known as the main "female hormone," but men also have it. High levels of estrogen can actually decrease testosterone levels. Key ingredients in Alpha JYM may help support a healthy estrogen balance.*

3) Antioxidant Support*
Alpha JYM includes ingredients that provide antioxidant support for testosterone-producing cells in the body. Free radicals can wreak havoc on the cells of the body, which disturbs the cells’ ability to function optimally. By protecting the body from this oxidative stress, Alpha JYM helps promotes healthy testosterone levels by allowing these specialized cells to function optimally.*

4) Freeing Up More Testosterone in the Body*
In healthy males, Alpha JYM may help the body free up more of its own testosterone.* In the blood, testosterone binds to the carrier protein sex hormone binding globulin (SHBG). This protein allows testosterone to circulate in the blood. However, SHBG naturally holds onto testosterone, often preventing it from leaving the blood and getting to the tissues in the body that need it, such as muscle fibers. In the muscle fibers, testosterone binds to androgen receptors, which instigates processes that lead to muscle growth. By helping free up more testosterone in the body, Alpha JYM helps put more of your natural testosterone to work.*

5) Supporting Optimal Testosterone Excretion*
In healthy males, Alpha JYM helps promote testosterone levels by supporting a healthy level of testosterone excretion. In the body, the enzyme UGT2B17 naturally converts testosterone into a molecule known as testosterone glucuronide, at which point it’s excreted from the body by the kidneys; in other words, you naturally pee out your testosterone. This lowers your body's overall testosterone levels.



Like every one of my JYM Supplement Science products, Alpha JYM is a non-proprietary supplement that uses the proper amounts of each ingredient and lists it clearly in the supplement facts panel. Alpha JYM’s six ingredients work to support the body’s natural levels of testosterone and were chosen based on real scientific data published in peer-reviewed journals as well as my experience with clients in the gym.*

I no longer need my job because of copy here Usa.work45.ℂℴℳ

Enlarged my prostate, went through a lot to make sure what was causing it. Mentioned it to someone asking about it on the JymArmy facebook page and was personally attacked by 2 admin and booted from the group when I didn't take their crap. Don't mess with your hormones or test "boosters" if you need something just get real test from the doctor.

I didn't notice any positive effects with this product, only negative. No improvement in the gym, decreased libido, Gatorade colored urine, and stomach upset. Nothing positive at all.

I feel better when I take this stuff. Like several people have said, I don’t feel this huge surge when I take it, it’s not like a pre-workout that you can feel when it “hits”. I know ashwagandha gives some people (including me) headaches, but I guess the dose is low enough for me I haven’t had a bad response to this. I haven’t measured my T before and after (I know, I’m amateur) but I feel more focused, more alert, and oddly enough, less anxious when I take this. In the gym and out. This stuff will always live on my shelf.

It's a 1 just because these pills made me really Ill. Symptoms was like have a really bad influenza, fever, muscle ache - I think it's funugreek that my body does not like - sure it's fine for many people but just be cautious if you haven't had Fenugreek before - made me real sick

Alpha Jym has changed my workout experience. I was out for 14 years before coming back to the gym. With Alpha, my strength gains have returned rapidly.. My energy is through the roof. All JYM products are outstanding.

Tried coming of off this for a couple weeks and began dragging *** and felt less motivated. I’m 31 now and this is a must have in my supplement cabinet.

Personally tested with blood lab tests, doubled my testosterone levels in two months using only a half dose! Staring testosterone: 200 After two months consistent usage (half dose): 500 I only used a half dose because while researching other brands I noticed that Alpha Jym has at least double the daily recommendation of the main ingredients in other respectable brands out there like Bodybuilding's Signature testosterone enhancer. Honestly I was just trying to save money and experiment with a minimum effective dose for myself. The ingredients are proven to work in countless studies, but TAKE NOTE that it is common knowledge that adaptogens like Fenugreek and Ashwagandha take several weeks to several months to effectively ramp up your body's hormone production mechanisms. So don't be that idiot that takes it for a few days and says, "DUR...I don't feel any different. And I didn't instantly gain 15 lbs of muscle and achieve a permanent hard on... pills must be garbage!" Alpha Jym has the same proven ingredients of the other good brands and actually at a better value. Would have expected no less from the man who revolutionized pre workouts!

I took one bottle (30 days) just to try it out. I didn't notice a lot of strength gains or change in sex drive, but I'm in my early 30's not mid 30's+ like the ideal target for that. And like I said, I've only used it for 30 days so far. However, I did notice a significant positive change in mood during the day after working out. I could tell the difference a few weeks after I ran out. I'm ordering more just because of that alone.

Hi. My name is Dan. I have been using Alpha Jym for about eight months now. I have a ton of more energy and stamina. I have lost approximately fifty pounds since I am able to hit the weights heavier and more often. I am now 68 years old and have a six pack for the first time since being a swimmer in high school. Thanks Doc!!!!!!!

Felt no noticeable change. Jym is a reputable brand so I can't bomb it with a bad review, but I can't give it a good one either. EVL Test did have a noticeable uptick in all of the typical test departments, so I'll head back to that.

Fantastic product. I have bloodwork that shows that it works for me. Been on it for over 2 years. Very happy. Use it with a few of my patients.

I am a fan of the entire Jym System, although not a priority for my supplement stack, I do use it from time to time and feel great when using it, Great price for what it is, some T boosters are going for $99+.
