Product Information



The Only Testosterone Support Product Designed and Used By Dr. Jim Stoppani
The ingredients in this bottle are what I have long recommended taking to support your body's own testosterone production. Each ingredient has science-based research to support its effectiveness at the doses provided in Alpha JYM. I designed this product, and all of the JYM products, for my own use. Now you have the same tools to maintain healthy testosterone levels-as well as optimize your strength, lean mass gains, and mental function.*

I’d buy it
Takes a full bottle to start getting the noticeable strength and fat burning potential. Mood improved by week 2. Great investment.

Helps old guys too
When I was 50 my workouts were more intense and more often, it was getting to where a long walk in the timber would wear me out. In about 3 weeks I can now carry a 30 lb ruck, which I could carry before, much farther and not be worn down after a couple miles. Great product, thanks, Tom G.

Better than I expected
I did not realize that this product could be taken by women, until a friend of mine posted that she used it. I immediately bought a bottle. I am a 68-year-old bodybuilder, and could use all the help I can get! I started out slowly, one cap a day, and progressed to 2 caps, then 4 caps, now 6 caps a day (regular serving is 3 caps twice daily). At 2 caps twice daily I noticed an immediate uptick in my energy levels, which translated into more intense workouts with less muscle soreness. I just now began taking 3 caps twice a day and hope to see even more improvement.

Is it ok for women?
A shopper on Feb 18, 2017
BEST ANSWER: Jim does not recomend it.
Take one does about an hour before you train and then another in the morning or night, depending on when you train? Does this mean to take it in the morning if you train in the morning, or at night if you train in the morning? Kind of confusing.
A shopper on Mar 4, 2017
BEST ANSWER: When you train determines how you take it. I train at night so I take one serving in the morning with breakfast and then my second serving with my pre-workout meal about an hour before I train. If you train in the morning you would take your first serving about an hour before your training session and then the second one in the evening, with dinner for example.

Is it useful/safe for younger athletes? (18-25)
A shopper on Mar 21, 2017
BEST ANSWER: It is not needed if you're younger than 21. Jim has said that the earliest you really want to take it is around 28. I know some people who are 24-26 that take it and claim to have seen results, however, I would advise NOT to take it below the age of 21 for sure.

A C on Feb 28, 2017
