Pre Jym Review - 16 Things You Need to Know

Pre Jym is a pre-workout supplement created by JYM to help create a more successful and energetic workout. They claim their product has 13 hand-picked ingredients in fully disclosed amounts with no additional fillers. We love that the website claims no proprietary secret blend, and invites us to take a look at their ingredient lists. The problem is… we couldn’t find any ingredient lists on the company website.

Due to the lack of information they provide, our research team was concerned about the actual ingredients and uses. Our research team looked deeper into what is in Pre JYM and if it can meet up to claims. Here’s what we found.

Pre Jym can be purchased through their Official Site.

Pre Jym Label

Here is a closer look at the actual label for Pre Jym supplement powder:

  • Creatine hydrochloride (2g)
  • Beta-alanine (2g)
  • Beet root (500mg)
  • L-valine (1.5g)
  • Betaine (1.5g)
  • Citrulline malate (6g)
  • N-acetyl-l-cysteine (600mg)
  • Taurine (1g)

You’ll also find L-leucine (3g), Black pepper (piper nigrum) (5mg), Alpha-glyceryl phosphoryl choline (150mg), L-isoleucine (1.5g), L-tyrosine (1.5g), Huperzine A (50mcg) and Caffeine Anhydrous (300mg).

Note that this fitness supplement does contain 300 milligrams of caffeine per serving, so watch for side effects if you choose to use it more than once daily, especially if you drink caffeinated beverages such as coffee, tea and energy drinks. The directions warn against mixing Pre Jym with other caffeine products.

The Mayo Clinic says that up to 400 milligrams of caffeine per day appears to be safe. A basic cup of coffee contains about 100 milligrams while energy shots and drinks average around 200 milligrams per serving. When considering taking the supplement, you should always factor in all caffeine sources you’re consuming.

Pre Jym benefits

Benefits

Pre Jym Benefits

Okay, here is a closer look at the benefits you could see while using Pre Jym pre-workout powder.

  • More intense workouts
  • Higher energy levels
  • Enhanced muscle strength
  • Better endurance and stamina
  • Improved focus
  • Faster recovery
  • Bigger muscle pumps and growth

The formula of Pre Jym is broken down into the following matrices:

  • Power/Strength & Endurance Matrix
  • Maximal Pump/Vascularity & Energy Amplifier
  • Fatigue-Fighting Anabolic Activator
  • Focus & Drive Intensifier
  • Absorption Enhancer

The Pre Jym website also says that the product has no proprietary blends, aka keeping “the doses of each ingredient secret” on the label. Some companies would argue that this is because the formula is so good that they want to avoid having it stolen by competitors.

Pre Jym says that proprietary blends “allow supplement companies to hide how little of each ingredient they’ve actually put in a product. This results in cheap, under-dosed, ineffective supplements.”

“Pre JYM doesn’t use proprietary blends. Take a look at its supplement facts panel, and you’ll see the actual doses of all 13 ingredients. I have nothing to hide. I’m proud of the amount of each and every ingredient I’ve included.”

Since this is a pre-workout product, it is intended to be combined with regular exercise and strength-training to get the results that are mentioned.

Directions

How to Take Pre Jym

To use the Pre Jym powder, you need to add one scoop to 14 ounces of water and mix well. Drink this 30-45 minutes before your workouts. Though it is a bit unclear, it appears that this fitness supplement should only be used once per day.

Ingredients

Pre Jym Ingredients

We’re going to hone in on the important ingredients in the Pre Jym supplement to give you a better idea of what each substance has to offer along with the research that supports it.

Pre Jym ingredients

Creatine hydrochloride

According to Examine.com, creatine hydrochloride is a molecule that’s often added to supplements to help support cellular function and enhanced workout performance. It’s naturally found in (produced by) the body as well as in meats, fish and eggs.

A research from Current Sports Medicine Reports (CSMR) has shown that creatine supplementation can help improve muscle performance and boost workout intensity, especially for weight training.

Beta-alanine

Beta-alanine is a building block of the dipeptide carnosine. It’s often added to workout supplements to help improve overall endurance and exercise performance, as stated on Examine.com.

The International Journal of Sports Medicine says, “The effect of 30 days of beta-alanine supplementation (4.8 g per day) on resistance exercise performance and endocrine changes was examined in eight experienced resistance-trained men. Results indicate that four weeks of beta-alanine supplementation can significantly improve muscular endurance during resistance training in experienced resistance-trained athletes.”

Beetroot

Beetroot is a red plant with a rich source of folate and manganese used for food, food coloring and medicinal purposes.

Pre Jym

The journal Nutrients tells us, “In the human studies to date, beetroot supplementation has been reported to attenuate inflammation, avert oxidative stress, preserve endothelial function and restore cerebrovascular haemodynamics.”

L-valine

According to PubChem, L-valine is a branched-chain essential amino acid that helps with tissue repairs, muscle growth, and energy levels.

Amino Acid Studies reports, “Valine, in particular, helps to stop muscles from breaking down during periods of strenuous exercise. It does this by supplying extra glucose to the muscles for extra energy during intense physical workouts.”

Betaine

Also called betaine anhydrous or trimethylglycine, this substance is made in the body, and encourages proper liver function, carnitine production and cellular reproduction.

One study posted on Examine.com showed, “Oral supplementation of betaine at 2.5g daily over the course of two weeks appears to increase average (3.4%) and maximum (3.8%) peak power output on a cycling test (four 12s sprints against resistance) as well as average (3.3%) and peak (3.5%) mean power output relative to placebo.”

Amino Acids (Citrulline malate, Taurine, L-leucine, L-isoleucine, and L-tyrosine)

Amino acids are the building blocks of protein and they aid in muscle building and repairs. They also help by strengthening the immune system, supporting weight loss, boosting sperm quality, fighting signs of aging, reducing inflammation, and assisting with the health of nails, skin and hair.

An amino acid supplementation study in the journal Clinical Nutrition says, “There was a significant overall increase in lean body mass during the supplementation period. There was a gradual increase in lean body mass to a value of 1.14 ± 0.36 kg above the basal value at 12 weeks.”

N-acetyl-l-cysteine

N-acetyl-l-cysteine is a substance derived from L-cysteine (an amino acid). It is an antioxidant and is often used to treat Acetaminophen poisoning, according to WebMD.

Also, LiveStrong states, “N-acetyl-L-cysteine offers antioxidants to help prevent inflammation and cell damage, which make it potentially useful for various health conditions.”

Pre Jym ingredients

Black pepper (piper nigrum)

Black pepper is often added to dietary supplements to help increase the body’s absorption of important nutrients and other key ingredients in the product, as stated on the research done by the Expert Opinion on Drug Metabolism & Toxicology.

It is often sold under the patented name BioPerine and is found in a wide array of diet, health and fitness products.

Alpha-glyceryl phosphoryl choline

Often called Alpha-GPC, this is a cholinergic compound that is typically added to nootropics and mental performance supplements. It may also assist as a growth hormone supplement, according to Examine.com.

Huperzine A

WebMD states that this is a substance taken from a plant called Chinese club moss. It’s often used to treat conditions such as mental decline, and muscle weakness.

Caffeine anhydrous

A potent powder form of caffeine, which is typically used in supplements. Caffeine is a stimulant and mild diuretic. It affects the central nervous system and may elevate energy levels, focus, concentration and performance.

According to MedlinePlus, caffeine is a natural stimulant and is taken from plants, such as tea leaves, coffee beans, guarana, yerba mate, and cacao pods.

Some research posted on Harvard Health Blog has shown that caffeine may help boost memory and thinking skills.

Taste

Pre Jym Taste

Many Pre Jym users have found the taste too sweet or unpalatable, but there are also several online reviews that suggest the taste is not too bad. After a certain point, taste is a subjective matter.

One user said “I usually do not have a problem with taste even if its pretty bad, this one is just too sweet for my liking, I went with the cherry limeaide (sic) flavor and I even mix with about 20-22 ounces of water and it is still very sweet.

“I assume they had to do this to mask the amount of ingredients in this product as the scoops are pretty large at 26.5 grams per serving. The product also burns my stomach a bit after I am done drinking it, this once again could be contributed to amounts of specific ingredients in this product. Overall taste 7/10.”

While a less satisfied customer said on Bodybuilding.com forums “I love this PWO despite it’s high pricetag. However, I thought the cherry limeade was pretty gross. Tasted like cough medicine, once I was near the end of my bottle, I would feel like vomiting from the taste and bloating I get from drinking so much of it. ”

Pre Jym side effects

Side Effects

Pre Jym Side Effects

Based on the user feedback we found online, some Jym Pre workout side effects people have experienced include the following:

  • Upset stomach
  • Nausea
  • Headache
  • Jitteriness
  • Shakiness
  • Fast heartbeat

A warning on the product’s label does point out that Pre JYM contains 300 milligrams of caffeine per serving, which is the equivalent of about three cups of plain black coffee. You should avoid using this supplement with any other caffeinated products.

Also, WebMD points out that when too much is consumed, “caffeine can cause nervousness and restlessness, stomach irritation, nausea and vomiting, increased heart rate and respiration, and other side effects.”

Since this pre-workout product also contains huperzine A and creatine, it may cause some other side effects. For instance, Drugs.com points out that Huperzine A can lead to, “adverse reactions including nasal obstruction, nausea, vomiting, diarrhea, dizziness, thirst, and constipation.”

In addition, the Mayo Clinic reports that creatine may lead to side effects including muscle cramping, fever, weight gain, nausea, dizziness, water retention, dehydration, diarrhea and gastrointestinal pain.

ConsumerLab clarifies that “this warning is legally required by the state of California for dietary supplements and many other products sold in that state which expose you to levels of one or more chemicals that may cause reproductive harm.

The list of chemicals that can trigger a warning includes hundreds of compounds but, unfortunately, the California law (known as Prop 65 or the Safe Drinking Water and Toxic Enforcement Act of 1986) does not require businesses to say exactly which compound is the reason for the warning.”

ConsumerLab also clarifies that California is the only state that requires this warning on supplement labels.

Results

Pre Jym Results – What to Expect

You should be able to feel the difference the first time you use Pre Jym due to the stimulants it contains. However, you may not see any solid results right away. After reading all sorts of Jym Pre workout reviews around the web, we noticed that some users saw results in the first week, while others mentioned noticeable results after eight weeks.

How fast you see results depends on a few different factors, such as how much you workout, your diet plan, and how your body responds to Pre Jym powder. Some customers also reported no energy boost at all from this pre-workout supplement.

Where to Buy

Where to Buy Pre Jym

You can buy Pre Jym from distributors such as GNC, Amazon, and bodybuilding.com. In fact, there is a direct link to each of these websites on the official Jym Supplement Science website. On the other hand, you will not find a Pre Jym sale on the company website itself. You must purchase this pre-workout product from authorized dealers.

Price

Pre Jym Price

The cost of Pre Jym powder depends on where you buy it. Here is a rundown of the price per dealer:

Amazon

  • $49.99 (30 servings)
  • $37.99 (20 servings)

GNC

  • $39.99 (20 servings)
  • $49.99 (30 servings)

Pre Jym cost

Bodybuilding.com

  • $37.99 (20 servings)
  • $48.99 (30 servings)

While Pre Jym itself does not offer a return policy or satisfaction guarantee plan, the dealer or distributor may offer a money-back guarantee of their own.

What About Post Jym?

Post Jym is another product available from Jym Supplement Science. Unlike Pre Jym, this supplement is used 30 minutes after your workouts and aims to help with muscle growth, faster recovery, improved strength and better endurance. It is also a powder formula that is added to water (16-32 ounces). Here is what it contains:

  • L-Glutamine
  • Creatine hydrochloride
  • Beta-alanine
  • L-Carnitine l-tartrate
  • Betaine
  • Taurine

Along with L-Leucine, L-Isoleucine, L-Valine and Black pepper fruit extract.

As you may have guessed, you can use Post Jym in combination with Pre Jym to help with muscle recovery and growth.

Pre Jym vs. C4 Ultimate

C4 Extreme Energy is a pre-workout supplement by Cellucor. Like Pre Jym, it aims to boost workout intensity, help you build more muscle mass, elevate energy levels, and improve overall performance.

It is also a powder that you add to water (6-8 ounces) and consume 20-30 minutes before exercise. It’s available in several flavors.

Here’s a look at the ingredients in C4 Extreme Energy:

  • Beta-Alanine
  • Creatine Nitrate
  • Arginine Alpha Ketoglutarate
  • N-Acetyl-L-Tyrosine
  • Caffeine anhydrous
  • Velvet bean
  • Theacrine
  • Rauwolfia vomitoria root bark
  • Huperzine A

As you can see, C4 Extreme Energy contains five of the same key ingredients as Pre Jym. Therefore it may have a similar impact and deliver similar results.

Other JYM Supplements

According to the official website, there are seven other JYM supplements available, aside from Pre Jym pre-workout powder. These products include:

  • ZMA Jym (helps with recovery, vitality, immune function and strength)
  • Alpha Jym (a testosterone booster for men)
  • Vita Jym (a complete vitamin and mineral supplement for athletes)
  • Omega Jym (a fish oil supplement for joint, heart and mind health)
  • Shred Jym (a fat loss supplement)
  • Pro Jym (a muscle growth formula for increasing muscle size and strength)
  • Post Jym (a post-workout recovery and growth product)

What Users Are Saying

“Pre Jym is well planned and transparent about the ingredients in it. That being said, don’t expect to get a huge pump from one scoop, especially if you want to eat before your workout. Another thing to know is that if you are doing intermittent fasting, this will theoretically BREAK YOUR FAST. Because it has BCAAs, this will trigger an insulin response on your body and it will, in theory, break your fast. That being said, you are still not eating so there will still be some benefits if you use it. BCAAs are great for keeping muscle mass.”

“My entire back turns red, itches and tingles when this kicks in, and lasts for 20-30 minutes. The post Jym doesn’t do this, only the pre. Be careful.”

“First off, JYM doesn’t do much in the actual gym. You can compare ingredients to other preworkouts but it doesn’t feel like they’re all there. I don’t feel the energy in the workout like I do with others, the effects are comparable to a 5 hour energy shot in all honesty. Look elsewhere for a better product.”

Bottom Line

The Bottom Line on Pre Jym

We must admit that Pre Jym offers an impressing ingredient formula to help build muscles, boost endurance and speed up recovery after workouts. Not to mention, this pre-workout powder comes in several flavors, which gives customers some options. Then again, there are a few concerns we have as well:

  • Plenty of users have complained that Pre Jym powder is too clumpy and tastes unpleasant.
  • Jym does not provide a 100% satisfaction guarantee, which means you’re unlikely to get a refund if needed.
  • This fitness supplement may cause some unwanted side effects like nausea, upset stomach and headache, at least according to some customers.

If you really want to take your workouts to the next level, build those muscles and boost vitality, consider a program that can help you stay on track and make healthier choices.

One program that stands out is Noom. Not only does Noom offer extensive food and exercise tracking, but the system also includes personalized meal plans and human coaching, which is something we have never seen before.

Now, the company supporting Noom is offering Dietspotlight readers a 14-day trial to get you started. It’s that easy!

  • All-in-one pre-workout: Great for morning gym & to get you through the day. NOT for night gym, unless you want to stay up.
    Joseph McD (Verified Purchase)

    I actually love the taste. While the benefits of BCAAs, especially without all the other EAAs, is highly contestable, I go to the gym straight after a stir-fry veg/egg based breakfast, so the BCAAs are of little to no interest to me. I found the product after searching for the one pre-workout that had appropriate dosages of caffeine and taurine for the energy hit, plus along with appropriate dosages of Beta-Alanine, Betaine, Citrulline Malate and BCAAs. As stated above, I’ve since changed my mind on BCAAs: I don’t really need them in supplementation (also see Athlean X’s test for BCAAs: this fails it, but I don’t really care – then again, Jeff Cavaliere of Athlean X is not a chemist). But the other supplements in the mix I was definitely keen on, and I don’t really caffeine-crash til the evening (ie I gym in the morning: I would not be taking this supplement if I gymmed at night).

    I can’t seem to find anything in regards to how long the effects last. Can I take it before a nighttime work out and still sleep?

      It says you should not take it 6 hours before your bedtime. I take it at about 3 or 4 pm and am good to sleep when I go to bed around 10.

        I would stay away from nighttime workouts if you are sensitive to caffeine. I will take it for my nighttime workouts but I make sure that I do as much as I can at the gym to burn off all the caffeine. Definitely the best PWO I’ve tried.
