I have tried some other pre-workout supplements, but this one is the absolute best. I am able to put a lot more into my workouts and feel strong throughout. I don't know why I would not take this before working out again.

One of the best out here right now
Surprised at the negative reviews here then I see what they're based on. If you're one of those people who rate a pre workout based on its flavor alone then you probably shouldn't be reviewing supplements at all. I've used everything from old school Jack3d to C4 and this isn't the best tasting supplement I've ever used... but the product itself far exceeds any other supplements in its category based on ingredient profile and results. Unlike other preworkouts this isn't just a tingly boost of caffeine fueled energy followed by a crash 2 hours later. It includes nootropics to help with focus and mental clarity, as well as a clean, intense energy that will make you feel like the incredible hulk for the entire duration of your workout. No crash, no jitters, no itching skin. They knocked this one out of the park and I cant wait to see whats next from this company.

Good, but stalls over time
Great preworkout, but like everything out there you build a tolerance. It does not have the same effect on me months or years down the road as it did in the beginning, but good overall.

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.
