What the JYM Army is saying

All Jym all the time!

Been using Jym supplements exclusively for 7 years and have been more than pleased with my results, the availability, the flavors, and the science. The comfort and confidence I have when purchasing knowing I am getting the best quality products on the market makes spending the money much easier.

Pro JYM Protein Powder

Great product and an amazing new flavor

Words can’t describe how great Jym products are. I’ve been using them for 14 years and they just keep getting better. Jim nailed the newest flavor of iced tea lemonade. It’s just like a freshly brewed cup without the heavy sugar shot after each sip, best of it’s a pre-workout!

Steven R.

Pre JYM High-Performance Pre-Workout

Best post workout product on the market!

I workout 7 days every week and this ensures that I properly recover. Been using it for 12 years and I highly recommend it. Every flavor is amazing!

Ryan P.

Post JYM BCAAs+ Recovery Matrix Post-Workout

Best!

The best fish oil I’ve taken thus far. This product goes down easy, gentle on the tummy and does not have a fishy taste or smell. It’s the absolute BEST!!

Omega JYM Fish Oil

Great Stack!

I've been using Jym products for years. This is a great stack. Easy to use and great results.

JYM Alpha Stack

Creatine+ has me PUMPED!

Since I’ve received my Jym creatine+, I’ve mixing it with my PreJym plus and my last three workouts have been great. More reps, more weight, bigger pump. It’s an absolute game changer. Definitely need to keep this one in the rotation. Highly recommend giving this one a try.

Creatine+

Great product. Great Taste

This is personally my favorite flavor. I’ve been taking the JYM products for years and in my opinion, they are the best on the market. Very clean ingredients with the no crash and lots of energy. Would definitely recommend.

Mike H.

Pre JYM Plus Pre-Workout

Best Tasting

This has to be the best tasting greens I have ever tried. If you have tried the other greens out there and can't stand the taste. Give JYM greens a chance and you will be surprised how good they taste. They mix really well and you will notice a difference in your overall well-being.

JYM Greens

My all time favorite brand HANDS DOWN

I always go to Jym products; pre, protein and even other supplements they offer. The ingredients are top tier and I really love that theirs articles and videos on why Jim uses the stuff he does and the benefits. I HIGHLY recommend and almost tried ever flavor of protein available (even special releases) and have yet to find one I don't like

Pro JYM Protein Powder

Finally!

I’ve been using Jym supplements for almost a decade and I was so thankful when I heard Jim developed a caffeine free pre-workout. I struggle with caffeine sensitivity so I can’t really use his other pre-workouts. I have to find other brands but they are not as good. This stuff has been awesome! Please don’t discontinue this product and hopefully you’ll be adding more flavors. There are those of us that need this.

Pre JYM Pre-Workout - Stim-Free

The best protein blend!

This is our favorite protein blend on the market. Flavor, texture and consistency is always spot on. I hope this one stays in the line up and doesn’t go away. Thanks for creating a great protein powder that tastes great!
