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.*

Most complete Testosterone support available!
I would highly recommend any of the JYM supplements! Although I haven't been taking Alpha that long as of yet I foresee the same great results I have seen in the other products I have used. Stay Jym Army Strong!

My body doesn't like this product. I experienced explosive diarrhea within the first 24 hrs of taking this. To be fair, I stopped all other supplements & tried again a week later. Same result.

Best Test Booster
This is a great Test booster. I would highly recommend it. Clinical tested and proven ingredients with fully disclosed amounts (very rare in supplement industry), and more DIM than stand alone estro-regulators. Best test booster hands down.

Bought as a Gift
Bought for my husband as a gift as he is a big fan of Jim Stoppani and his JYM brand and he absolutely loved it.

Blockbuster Product
I use this daily along with Shred Jym. Both products are top notch. Again, amazing ingredients (you can't source yourself easily unless you are a world traveler) and proper dosing. Look up the many benefits on WebMD if want to learn more. Why is proper dosing important?! So the product actually works. If you take an 1/8 of an aspirin pill it effectively won't work. It's the same thing with supplements. Jim Stoppani always gets the dosing right and this is the official product, the Jym products sold on are not authorized products as Jim left that company and teamed up with GNC!!!
