If you’re looking for a quick review or don’t want to read the whole article (because we’re all short on time nowadays!), here’s a summary of our thoughts:
Pre JYM Pre-Workout Review at a Glance
- The ingredients are safe and effective for use before training or when you need a ‘pick-me-up’ in general
- It delivers a fantastic pump
- The label is transparent; no proprietary blends
- It contains excellent mental support compounds (AKA, nootropics)
- Some of the ingredients are underdosed, resulting in weaker effects
- While we found it to excel in the muscle pump department, it’s not the best pre-workout overall
- The energy benefits are noticeable but it causes jitters and energy crash as it wears off
- Many customers find the taste to be too strong and the price too high for what it offers

About Pre JYM
Remember we mentioned Dr. Jim Stoppani, the maker of Pre Jym 2.0, in the beginning? Let’s briefly go over who he. Dr. Jim Stoppani is an owner of JYM Supplement Science & JimStoppani.com. He has a Ph.D. in exercise physiology and had worked as the science editor at Muscle & Fitness for 10 years.
Pre Jym is his creation – a highly popular pre workout supplement that’s been on the market for years. Recently though, Pre-JYM has been upgraded to Pre-JYM 2.0 which has a bit different ingredient profile. You can buy it on the official Jim Stoppani website or Amazon.
One thing you’ll see customers always complaining about is the price of Pre-JYM: 20 servings for $38 and 30 servings for $49. There’s a reason why pre-workouts cost this much, some of them source high quality ingredients and are costlier to produce.
Pre-JYM has a clear and transparent label, which is definitely better than some other pre-workouts we’ve reviewed, such as Dark Energy.
Pre JYM Flavors
What’s cool, you get to pick from 8 different flavors, some of which are excellent, others not so much (according to our personal preference at least):
Pineapple Strawberry, Black Cherry, Grape Candy, Pink Lemonade, Rainbow Sherbet, Refreshing Melon, Strawberry Kiwi, and Tangerine.
There’s one thing we love about Pre-JYM Pre-Workout that we can tell you right off the bat; its transparency. Ingredient dosages are clearly shown on the Pre-JYM label, which helps us asses how (in)effective this pre-workout will be for you.
However, there are some things about this pre-workout that we didn’t like, such as having some ingredients underdosed. We address this in more detail below!
How to use Pre Jym 2.0
Pre JYM comes as a powder, which means you mix it with 12-32 oz. of water and drink about 30 minutes before your workout.
Keep in mind that Pre JYM has 300mg of caffeine per serving, which is equal to about 2-3 cups of coffee. It’s better to start with just half a scoop (or a third!) if you don’t tolerate caffeine well.
Pre Jym 2.0 Ingredients
Pre Jym 2.0 consists of 13 ingredients, most of which are safe and well researched. Here’s a closer look in case you could’t quite make that out;
- Caffeine (300mg);
- BCAAs (6g): 3g leucine, 1.5g isoleucine, and 1.5g valine;
- Creatine (2g);
- Beta-alanine (2g);
- Citrulline malate (6g);
- Taurine (1g);
- Betaine (1.5g);
- Tyrosine (1.5g);
- N-acetyl L-cysteine (600mg);
- Alpha GPC (150mg);
- Beet root extract (500mg)
- Toothed clubmoss extract (50mcg);
- Black pepper extract (5mg).
Now, it’s time for the fun part — ingredient breakdown! Let’s see how each of them will work for you.
Caffeine is the most popular ingredient in any great pre-workout. However, 300mg per serving is… A LOT! It lookes like Pre Jym doesn’t skimp on it at all. Several studies showed that caffeine is believed to improve your workout performance, boost mental focus, and even help you burn fat. One thing’s especially true when it comes to caffeine, and that is: too much of a good thing is a bad thing!
BCAAs (or branched-chain amino acids) are believed to boost endurance, fat loss, and mental focus. You’ll see many pre-workouts with BCAAs as they’re often referred to as “the building blocks of muscle.” The downside is, BCAAs act as inhibitors of l-tyrosine, holding back the production of mood-regulating dopamine and serotonin neurotransmitters.
Creatine is one of the most researched and safest pre-workout supplements that enhance energy production and strength. What’s more, studies proved creatine is the most effective legal supplement that helps you gain muscle. A typical diet provides 1–2 grams of creatine per day, while for growing the muscles, you need to take 5–22 grams of this supplement. Still, people with kidney disease should avoid it before talking to their doctor!
Beta-alanine is believed to improve athletic performance by reducing fatigue and boosting endurance. But don’t jump on it yet! Some people are annoyed by the common side effect of beta-alanine – paresthesia. This is a tingling sensation throughout the body, especially around your face, neck, arms and legs, and can be distracting during workouts. If you don’t mind it though, you’ll love it!.
Citrulline malate is an amino acid that often goes under the radar in pre-workout supplements. It’s the best muscle pump ingredient. While we want something that will give us a boost immediately (e.g., caffeine), citrulline malate works in the background and builds up in your body when taken regularly. 8 grams is the most effective dose, while Pre Jym uses 6 grams. Is the dosage too low? A bit, yes!
Taurine is a popular pre-workout ingredient that boosts mental focus while increasing blood flow to working muscles – not many fitness enthusiasts know this!
There are two “BUTs” here:
- To see the desired results, you need a dose of 2g, while Pre Jym uses only 1g. Verdict: definitely under-dosed!
- Taurine combined with caffeine blocks its effectiveness, which means caffeine will not give you the full ‘punch’.
Betaine is one more great pre-workout ingredient that combines well with beetroot, which helps all the ingredients absorb more effectively. It might increase muscle strength and size by boosting creatine production in the body. One study showed that men who took 1,25g of betaine twice a day increased their muscle strength by 25%. But since Pre Jym uses only 1,5g per serving, we can’t say you will get the same results.
Pre Jym kicks butt when it comes to mental benefits. Tyrosine is a great compound that supports your overall mental wellbeing while reducing the stressful effects of the workout. It’s well-dosed, too!
L-cysteine reduces cell damage during training. But again, the dosage here is too low to have a notable impact.
When it comes to Alpha GPC, it provides extra power and better focus. Guess what we’re going to say next? Same old story — the Alpha GPC is more effective at doses that are higher from what’s found in Pre-JYM 2.0.
This is a source of Huperzine, a compound that helps to enhance memory and brain function. We don’t like this one because it has shown to lead to side effects when taken long-term.
As we mentioned before, you can easily buy Pre Jym 2.0 on Amazon and via the Jim Stoppani website. On Amazon, it has 3,516 reviews, and on Jim’s website – 218.
A lot of users don’t like the taste of Pre Jym 2.0. One Amazon customer said; “Worst tasting preworkout supp I have ever tried. Yes, it may have the good ingredients but I have stopped looking forward to my workouts because of this. I’ve tried so many for the past 15 years and have never hated preworkout as bad as this one. I still have half a bottle and I’m throwing it in the trash and moving on to the next.”
Another person shared a more positive experience using Pre-JYM: “If you are expecting this to taste terrible like all the bad reviews are suggesting, it isn’t that bad. I don’t know if thats because I was expecting the worst, and it ended up not being the worst, but I can say it wasn’t as bad as the reviews claim that it is. Sure, it doesn’t taste like candy, and it isn’t going to be the most tasty thing you’ve ever had. But that’s not the point. The point, is that it is a pre-workout drink. And you are working out to get stronger. So first, to get stronger, get a little bit of a tougher and just drink it. It isn’t terrible, so don’t act like a toddler.
The only problem I think I found with this, is the amount of caffeine in the mix. Now I’m fine with caffeine but the amount thats in here is claimed to be like 3 cups of coffee, but it feels like its more than that. It will get your heart racing, and I strongly suggest you start out slow and build up to your tolerance level since everyone is different. I weigh just above 200 lbs and I can take one full “serving” but it took me a week to get up to that point, since it just made my heart go faster than I thought it naturally should.”
Does Pre Jym 2.0 Have Side Effects?
Since there is a high dose of caffeine, some people may experience:
- increased heart rate
If you are sensitive to caffeine, start with a smaller dose (half a scoop) to avoid these unpleasant side effects. Again though, everything depends on your body.
And of course, consult with your doctor if you have any medical questions – we don’t give advice around here!
Our conclusion? Pre Jym 2.0 is a relatively good supplement with (mostly!) safe and high-quality ingredients that will give you a solid pre-workout boost. Should you try it? We don’t see any strong reason to say no. If you’re not looking for some extra results (vein-popping muscle pumps), then why not? Give it a shot!
The label is transparent, and all the ingredients are safe and clinically proved to be great pre-workout supplements.
Now for the downsides – starting with caffeine. There’s a bit too much of it in Pre-JYM for our liking. If you’re sensitive you should’t take a full scoop, at least not at first.
Another issue with Pre JYM is that many of the key ingredients are under-dosed, especially those related to mental focus, motivation, and energy. It’s also missing L-Theanine to help smoothen out the jitters you may get from the high caffeine dose.
From our own experience and many customers’ reviews, the taste is a bit too strong while the price is relatively high.
So, let’s wrap it up: Pre Jym 2.0 is a nice pre-workout supplement for general use that delivers the pump and concentration. However, it doesn’t quite rank as one of the very finest pre-workout supplements on the market today.
