Introduction to our Pre Jym Review

Pre Jym is a pre-workout supplement that is formulated to help you get the best out of your workouts. Pre-workout supplements aim to make sure that your exercises are actually worth all the hustle. These products are not just beneficial in that they’ll help to increase the results, but they are also supposed to make your work at the gym a lot easier.

How so? Well, the first role of any pre-workout supplement is to make sure that your energy levels are as high as possible. This puts you in a unique position where you can undertake more strenuous workouts with more ease and for a longer duration.

This will inevitably lead to better results achieved within a much shorter period. Next, Pre-workout supplements are supposed to improve your focus in the gym. Concentration is critical for any bodybuilder. It ensures that your body and mind are synchronized for better results.

Another benefit stemming from enhanced focus is that the likelihood of accidents and injuries occurring is reduced significantly.

Pre Jym is one of the many pre-workout supplements in the market. This supplement is manufactured by Jym Supplement Science founded by the renowned bodybuilder Jim Stoppani. He is also a doctor in exercise physiology and the former science editor for Muscle & Fitness. It’s therefore fair to assume that the supplement has everything a fitness enthusiast needs in a pre-workout supplement. But, does it really?

Pre Jym is linked to some fitness benefits. Unfortunately, these benefits have been overshadowed by the recent rumors that it can cause cancer. These are no ordinary rumors, and hence it’s upon us to get to the bottom of these reports and determine if indeed the supplement has carcinogenic compounds.

Before we get into the finer details of what is contained in this supplement, let’s first take you through what the manufacturer claims the product can achieve.

Benefits of Pre Jym

  • Increase mental focus

Like I’ve already told you, mental focus is crucial in various ways. It helps in making sure that you are never distracted when working out. This boosts the brain-muscle connection which translates to better results.

  • Boosts endurance

Pre Jym is supposed to increase stamina in various ways. The manufacturer claims that it can reduce muscle fatigue thus allowing the muscles to withstand rigorous training for a prolonged duration. Some reports also argue that it can reduce muscle pain and failure.

  • Build massive pumps

This should be very enticing to all the guys out there who cherish massive pumps for the sake of selfies. These should motivate you into working out harder for even better results.

  • Increases energy

All the mental focus and endurance would be useless if you don’t have the energy necessary to step into the gym in the first place. The Pre Jym formula is supposed to ensure that you never run out of energy while working out.

Pre Jym Ingredients

How is Pre Jym supposed to achieve all this? Let’s take a closer look at the list of ingredients:

  • Creatine Hydrochloride

Creatine Hydrochloride’s presence here is a bit confusing, Yes the compound has a decent reputation of promoting muscle protein synthesis, strength and the production of adenosine triphosphate but it has to be used on a daily routine. Therefore, the compound may not be beneficial in a pre-workout supplement, and hence the user may not feel its presence at all.

  • Caffeine

Caffeine is a crucial ingredient found in almost all top pre-workout supplements. It increases mental focus while also boosting energy levels.

My only issue with the caffeine included in Pre Jym is the dosage. At 300mg, the risk of adverse reaction is very high. The guys who are sensitive to caffeine will have a hard time taking this supplement without experiencing any complications. Therefore, it’s crucial that you take the supplement cautiously.

  • Beta-Alanine

Muscle fatigue, failure, and pain are as a result of the accumulation of lactic acid in the muscle tissues. This happens after extended or strenuous physical activities. Pre Jym is formulated to prevent muscle fatigue, failure, and pain by slowing down the accumulation of lactic acid. Bet-Alanine is the ingredient responsible for that.

Pre Jym contains just 2g of Beta-Alanine yet most reports claim that one needs to take at least 3g for the ingredient to be effective. Therefore, the only way to get enough Beta-Alanine in your system is to increase the amount of Pre Jym you are taking.

Here is the problem though; by increasing the Pre Jym you are taking, you’ll also be increasing the levels of caffeine you are consuming yet the stimulant is already found in excess in each serving.

  • Citrulline

Citrulline promotes the production of nitric oxide (NO) in the body. High levels of NO increases the dilation of blood vessels leading to impressive pumps, increased endurance, and faster recovery. Pre Jym contains 6 grams of Citrulline which is enough to yield all the desired effects.

  • Branched-Chain Amino Acids (BCAAs)

BCAAs are crucial for muscle growth. Some reports are even showing that Branched-Chain Amino Acids Leucine is the compound that triggers muscle growth in the body.

While the benefits of BCAAs are almost undebatable, their efficacy in pre-workout supplements is very questionable. Most experts will tell you that it is more beneficial when used after your training sessions. If used before training, BCAA can actually result in fatigue.

  • Betaine

This amino acid increases strength and power. It will make your tedious workouts seem much easier thus expediting your growth in the gym.

  • Bioperine

Bioperine is found in many sports supplements. Its role is to facilitate the absorption of the other ingredients contained in the supplement. This makes sure that all the compounds present are not excreted, but instead, they get into your system.

  • Huperzine A

Huperzine A was included in Pre Jym when the manufacturer made changes to the Pre Jym formula. It was added to improve focus and muscle performance.

The other ingredients contained in this formula are taurine, n-acetyl l-cysteine, beta vulgaris, l-tyrosine, and alpha-glyceryl phosphoryl.

So, are these ingredients really carcinogens or are those mere rumors. The reason behind these rumors is that the supplement contains some ingredients that are listed in the Proposition 65 of the State of California which lists hundreds of compounds that are said to be carcinogens.

You’d be shocked when you realize some of the compounds found here. Talk of fluoride, wool, amino acids, alcohol, plastic, contraceptives, etc. Using this list, we won’t just be saying that Pre Jym causes cancer, but we will also go on to name hundreds of other things such as food blenders. It’s, therefore, a bit unfair to single out Pre Jym without producing an independent trial that links the supplement to cancer directly.

According to Jym Supplements Science, you need to take this supplement 30 to 45 minutes before starting your workouts. Each scoop of the supplement should be taken with 12-32 ounces of water.

To deal with the after taste issue, Jym Supplement Science provide this supplement in different flavors such as pineapple strawberry, black cherry, and refreshing melon flavors.

Side Effects of Pre Jym

The following are some of the commonly reported side effects of Pre Jym:

  • Insomnia
  • Stomach upset
  • Headaches
  • Nausea
  • Tingling
  • Feeling agitated
  • Irritability

Anyone who’s very sensitive to caffeine should seriously consider using Pre Jym in very low doses to avoid unnecessary complications. If you still can’t shake off the adverse reactions, you’ll have to stop taking the supplement altogether.

Breastfeeding and nursing mothers should also avoid using this supplement. You must also consult your physician before taking Pre Jym if you have a pre-existing medical condition.

Pre Jym Review Final Thoughts

We hope our Pre Jym review has helped shed light on this supplement. Pre Jym contains a couple of proven ingredients, but it still falls short. Even our analysis on the user reviews came back average at best. The high levels of caffeine are also something to be cautious about.

In summary, if you are looking for explosive workouts, you’re better off going for a more proven supplement with potent ingredients.
