Simply the Best...
I am not a big fan of stimulant based pre-workouts (beyond caffeine) because of the nervous jitters I experience, along with the fact I quickly build-up a tolerance. Additionally, many are lacking basic pre-workout ingredients and mask low-levels of product under a "Proprietary Blend" matrix. With Pre JYM ,I know exactly what I'm getting and in the exact doses....there is no guesswork involved. I don't need to stack Pre JYM with some of this, some of that, and a bunch of other guesswork ingredients since I'm not sure what's in most pre-workout supplements other than a boatload of stimulants...some of them potential dangerous or little studied.

Pre JYM gave me everything I needed nutritionally to experience solid workouts with good energy, excellent focus and strength, and great sleeve-tearing pumps; I feel as though I am having a very good day at the gym without feeling like I am hopped-up on drugs. My energy, strength and mental focus simply coalesce into an outstanding workout with a very natural feel to it. Moreover, while I often have the energy to workout for another hour, I retain the ability to realize that I have met or exceeded my workout objectives (e.g., chest, triceps and obliques) in 70-minutes of very intense training, and to continue would be counter-productive since I tend to over-train when taking other PWOs.

Overall, I am very please with Pre Jym since it helps get me energized and motivated to workout, provides me with the nutrition I need to fuel gains in the gym, and does not interfere (e.g., post-workout crash and measuring a cornucopia of supplements so I know what I am taking). After all, I'm just a normal hard-working guy trying to stay in shape without this routine/lifestyle--call it what you wish--consuming all my limited free-time. As far as negatives, Pre JYM is not the best tasting pre-workout on the market. Then again, it mixes well and all the flavors taste pretty good and, considering how many bitter tasting ingredients in contains, it's quire remarkable how good they taste.

No going back!!
Best pre workout I've tried hands down. Been using it for a year now and I won't use anything else. I used C4 and others before and it would wreck my stomach pre workout. This stuff is clean and Jim stoppani gives unlimited tips on social media on how best to mix and use the stuff. Might seem pricey but you get what you pay for, scoop size is huge! The natural island punch isn't for everyone due to the use of the natural sweetener Stevia. If you use Stevia then go for it, it's like a tart tang but I'm not a fan of aritifical sweetness so this is perfect for my lifestyle. Enjoy!

The best together.
Another home run. Great by itself, but unbeatable when you use it along side the Post.

This is a GREAT pre workout. Fully dosed and listed ingredients no hiding behind proprietary blends. Not only does it give great PUMP, energy and focus, but also feeds your muscles with BCAA's. I actually prefer the natural island punch flavor because it is not too sweet and a little tart. I would highly recommend using this pre-workout.

Best pre workout for me
I've been taking most of jym products for 3 years. Some taste good, others are not as good. I don't rate products based on taste. I rate products especially pre workouts based on effectiveness. Pre-jym is the most effective pre workout I've tried. It gives me energy at the beginning of my workout but as I warm up early in my workout I feel it's ignited. I have endurance to push myself through lifting, hiits, tabatas etc...

It works!
Best prework out I ever tried! I saw 1-2 extra reps in fundamental exercises. Great focus, intense clarity, noticeable pump. Regardless high caffeine concentration and rest of stimulating matrix, it gets out of the system shortly after workout completion, therefore you can still a get a good night sleep after a late evening workout. 6 g of citrulline combined with 2g of HCL creatine are a game changer. I would buy it again for sure!

Jym pre-workout
No crash with minimal jitters. I like the concept of the creators products - natural ingredients. The flavor "island punch" is mildly sweet. I will try other flavors for this is my first purchase. If you purchase Jym protein powder, Tahitian vanilla bean tastes amazing.
