Jym Pre Workout Review: Our Experience

There are quite literally hundreds of pre-workouts on the market, some of them all-natural, and others embrace artificial ingredients to get better results. Regardless of which end of the spectrum you stand, you will no doubt have heard of the Jym pre-workout, it is one of the best on the market and has yielded results. 

But, swallowing what the manufacturer says about their product can be unhelpful at times, with so much positivity surrounding a product it can be difficult to root out what exactly the product is like. 

Well, in this article, we are going to have a look at this product in detail based on our experience with it. 

What Is Jym Pre-Workout?

Jym is the brand name of a company that was founded by Dr. Jim Stoppani, who has worked as a science editor at a place called Muscle & Fitness for over 10 years.

The pre Jym pre-workout supplement is a great product that gives you that extra energy boost to really help you get into your workout and push yourself that bit further to improve your muscle and fitness gains. 

It comes in several flavors such as orange mango, cherry limeade, rainbow sherbet, and several others. It is a powder you mix with water and drink before a workout, the ingredients are supposed to help your workout performance and improve your recovery. 

But what ingredients does this product contain, and what do they do for your body?

What Are The Ingredients?

Whenever you buy anything, especially where performance-enhancing products are concerned, knowing what exactly goes into the product can be a huge factor in selling that item. The pre Jym pre-workout supplement powder is a great performance-enhancing, energy booster that you take before going to the gym. 

We know that it is important to know what you’re putting in your body, so we found out what ingredients were in this popular pre-workout supplement. 


This product has 300 milligrams of caffeine in it, which equates to about 2 cups of coffee. If you do not have a tolerance for caffeine, you might find that it is a little much for you. You might prefer a caffeine-free pre-workout such as Post Jym instead. 

Branched-Chain Amino Acid

This product contains Branched-Chain Amino Acids or BCAAs, these are basically a group of essential amino acids that cannot be made by the body. This means that you will need to consume food to obtain them. The following BCAAs are in this pre-workout:

  • 3 Grams of Leucine
  • 1.5Grams of Isoleucine
  • 1.5 Grams of Valine

These supplements will be helpful in building muscle, reducing muscle fatigue, and alleviating muscle soreness. So, the inclusion of these supplements in your pre-workout will not only help you deal with the discomfort post-workout, but they will also help you gain muscle, which is a goal of many people that take this pre-workout.

Directions For Use

Directions For Use

The instructions on the bottle are clearly written and keep in mind people’s tolerances to substances like caffeine. 

You will begin by taking 1 scoop of the supplement and putting it in a glass with between 16 and 24 oz of water and drinking the dissolved the pre Jym pre-workout at least 30 to 45 minutes before you hit the gym. 

If you are not used to a pre-workout, you are advised to use ½ a serving until you build up more of a tolerance.

Once you feel you are able to take a full dose of this product, you should not exceed more than 1 serving, this is so that you do not suffer from side effects like sleeplessness, this will be an especially rampant issue if you consume this product within the 6 hours before you go to bed. 

Benefits And Side Effects

We found that this product increased energy, focus, helped with strengthening muscles, and aided in faster recovery. It really puts you in the zone while you work out, helping you to focus.

Best of all, we did not experience a crash once the effects wore off, as well as that, there were no jitters once we took this supplement.

Now, everybody reacts differently to a product like this, some customer reviews found that a full dose of the Jym pre-workout gave them an uncomfortable feeling like ants crawling on their skin while others found that it caused severe flatulence.

With so many experiences and opinions out there, it can be tough to glean an honest answer and one that will be 100% perfect for you. You may experience a side effect that we did not while we used this product, the diversity of responses to this product can be diverse. 

Does It Taste Good?

Customer reviews on the taste of this product will vary widely, some found that it tasted great and had no issue, while others thought the taste was atrocious and could hardly get it down. 

When we tried this product we did not have any issue with the taste, while it was not amazing it was not unbreakable and has an almost pleasant flavoring. 

The Pre Jym pre-workout offers you nine flavors to choose from:

  • Orange and Mango
  • Rainbow Sherbet
  • Cherry Limeade
  • Pink Lemonade
  • Pineapple and Strawberry
  • Tangerine
  • Raspberry Lemonade
  • Grape Candy
  • Strawberry and Kiwi

While we have not tried all of these flavors, we thought that the orange and mango was one of the best. Customer reviews vary greatly on which flavor was best, or even if the product had an appealing taste at all. But for the most part, comments found that there were flavors that worked for most people. 

Pre-Workouts By Jym

Jym does several products on top of the pre-workout supplements, there are not a lot of different products that they do, but here are a few of them.

ISO Jym 100% Whey Protein

This is a protein powder that contains no fat, a full dose is worth only 90 calories. It is a protein powder that is lighter and more refreshing than traditional protein powder. 

So, if you want to try something a little different, this might be an interesting product to try out. 

Post Jym Dextrose Carbs

This product is designed to replenish the glycogen level in the muscles while enhancing the uptake of creatine and carnitine. It is an effective carbohydrate you can take after a workout. 

Post Jym BCAAs+ Recovery Matrix Post-Workout

This product is designed to take after a workout and helps your body to recover, rebuild and restore. It is a good product to take if you need to be able to recover faster after an intense workout. 

Mass Jym

This product is a special blend that will optimize lean muscle mass gain and help reduce body fat gain. You can use it as a meal supplement or as a muscle gainer, depending on your preference. 

Final Thoughts?

Overall, we found that this product was really great all around. It did what it said and did not have any adverse side effects that we found. That being said, there is the possibility that there will be side effects for other people, and several customer reviews supported this. 

The energy boost and focus that this pre-workout powder gave us was a great experience, and we feel that it does live up to the hype. It works well and gets results, which is everything we are looking for in a product like this. 

Our experience was quite good with this product, and we recommend taking it, however, it may not work perfectly in every case. But, the majority of reviews we read, and our own experience, really go a long way in supporting this product as a successful pre-workout that does what it says.

A good pre-workout. But one that has some problems with dosing and a few ingredients. There are more balanced products out there that will get you better results with far less side effects.
