Advanced bodybuilders do not mind going the distance to try anything that would help them perform better in the gym, and that is one big reason why pre-workout supplements becoming increasingly popular. Pre JYM is just another name in the list, with some serious promises to help you have better energy levels, improved strength, and better muscle gains.

What You Need To Know About Pre JYM

Pre JYM is marketed as a powerful pre-workout supplement, that uses an advanced formula to offer some amazing benefits. By combining L-citrulline, creatine, beta-alanine, and some stimulants, it claims to increase your stamina and strength. It ramps up your energy levels and helps you get better results from your workouts.

You can find it in many different flavors, including refreshing melon, black cherry, cherry limeade, strawberry kiwi, natural island punch, raspberry lemonade, rainbow sherbet, and orange mango. While the formula looks good on paper and some of its flavors are reasonably good, Pre JYM is not going to work wonders to increase your strength and stamina. Most of its ingredients are under-dosed and others lack the scientific evidence to support their use.

What Are The Side Effects Of Pre JYM?

Pre JYM contains some natural ingredients, but each serving provides you with 300mg of caffeine with some other stimulants as well. Therefore, it is common for people to experience side effects, such as increased heart rate, high blood pressure, sleeplessness, jitteriness, and more. Refer to our “Side Effects” section to learn more.

How Much Does Pre JYM Cost?

You will have to pay $37.99 to get a container of Pre JYM – you will be paying for 20 servings.

Our Verdict On Pre JYM

Pre JYM is a pre-workout supplement and makes several big claims because it contains 13 ingredients. While the ingredient profile looks impressive, most of the ingredients are fairly under-dosed or ineffective. L-citrulline is a good addition, but you do not get enough of it from each serving. The same holds true for beta-alanine, N-acetyl L-cysteine, Huperzine, and beet extract. Some of its ingredients do not make much sense – this is especially true for BCCAs. It is available in many flavors, but you may have to try a few to find what actually works for you. The price of this supplement is also on the higher side, which is another issue keeping people from trying Pre JYM.

Overall, we do not recommend Pre JYM to our readers.

Pre JYM Review

Pre JYM is a pre-workout supplement with 13 natural ingredients. It uses a combination of natural ingredients and stimulants to help ramp up your energy levels before your workout sessions. It claims to increase energy, stamina, endurance, and concentration. It also helps reduce fat and increase muscle gains. Unfortunately, it fails to produce positive results mainly because some of its ingredients are quite under-dosed, and others do not have enough scientific evidence to support their use.

One good thing about Pre JYM is that it contains a reasonable dose of L-citrulline. Some studies suggest that supplementing with L-citrulline may help improve muscle endurance. However, it is important to point out that many studies have used up to 9g of L-citrulline to produce positive results, whereas you are going to get 6g of L-citrulline in each serving of Pre JYM:

  • In an incline walking test until failure in otherwise healthy persons, 3 or 9g citrulline (acutely or over 24 hours, respectively) appeared to actually reduce time to exhaustion (0.8%, a clinically irrelevant degree) and suppressed the exercise-induced increase in insulin. Other biomarkers tested were unaltered, although heart rate trended to decrease with 3g citrulline.

Pre JYM Facts

  • Natural ingredients
  • Increased focus

Many other claims associated with L-Citrulline supplementation are not backed by scientific evidence. For instance, it is thought that it helps improve sports performance and concentration by increasing Nitric Oxide synthesis, but not enough data is available to support this claim. Some studies have observed positive results, but the effects are not that significant. For instance:

  • A double-blind randomized placebo-controlled 2-way crossover study was employed. Twenty-two trained males consumed 2.4 g/day of L-citrulline or placebo orally for 7 days. On Day 8 they took 2.4 g of L-citrulline or placebo 1 h before a 4-km cycling time trial. Time taken to complete the 4 km cycle, along with power output/VO2 ratio (PO/VO2), plasma nitrite and nitrate (NOx) and amino acid levels, and visual analog scale (VAS) scores, was evaluated. L-Citrulline supplementation significantly increased plasma L-arginine levels and reduced completion time by 1.5 % (p < 0.05) compared with placebo. Moreover, L-citrulline significantly improved subjective feelings of muscle fatigue and concentration immediately after exercise. Source

You will also find BCCAs in each serving of Pre JYM. Though you get 6g of branched-chained amino acids from Pre JYM, you do not really need to take a supplement with these amino acids. This is especially true if you are already taking a protein supplement because it also provides you with essential amino acids. You can get enough of it from dietary sources; in fact, anything that contains protein provides you with amino acids as well. By eating 25g of protein obtained from chicken, you will be getting 4g of BCCAs as well. It is worth mentioning that you really do not need to load up on BCCAs because studies do not support the claim that they promote protein synthesis. Some studies have observed results, but the effects are not that impressive. For instance:

  • “Studies in both elderly humans and rodents subjected to free leucine supplementation have shown that such supplementations indeed acutely improved muscle protein balance after food intake by increasing muscle protein synthesis and decreasing muscle proteolysis in the postprandial state. However, the few chronic studies conducted with such free leucine supplementations did not succeed in promoting an increase in muscle mass.”

How to Take Pre JYM

Here is what the official site says about taking 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.

Another popular ingredient found in Pre JYM is creatine. You get 2g of creatine in each serving of Pre JYM, which is supposed to help increase endurance, strength, and muscle mass. Some studies show that creatine may prove helpful in gaining muscle mass, but more research is required to conclude anything. The important thing is that you may already be getting a good dose of creatine from other dietary sources, and your liver can also utilize amino acids to produce as much creatine as your body needs. Even if you supplement with creatine, you may not notice a significant change in your performance or muscle gains. Moreover, it is found that creatine is not going to work for everyone, as it is likely to work for people with fast-twitch muscle fibers.

  • Most people have about 50 percent fast-twitch fibers (responsible for sprinting and jumping) and 50 percent slow-twitch fibers (responsible for endurance exercise), says Peter Adhihetty, Ph.D., assistant professor in the department of applied physiology and kinesiology at the University of Florida in Gainesville. Those guys should respond well. But people with 70 percent fast-twitch and 30 percent slow-twitch muscle will see even more results, he says.

It may help a bit with endurance training, but you may also end up gaining weight. It happens because creatine promotes water retention in the body and increases your weight. By pulling water into your muscles, it may make you look and feel bloated, which is never a good thing. It also suggests that the increase in muscle associated with creatine intake is mostly water retained by your muscles. You may lose it when you return to your normal diet, or try to lose water weight using a different training regimen.

It is worth mentioning that creatine is not going to lead to an increase in power and strength, as many studies have failed to notice any positive benefit. For instance:

  • Older athletes, aged 48-72. Creatine usage at 5g a day was unable to increase power output. Source

Another study shows that creatine supplementation may not lead to an increase in strength. For instance:

  • Increase in strength shown, but increase in power not demonstrated in either creatine monohydrate or PEG creatine groups. Was a comparative study between creatine monohydrate and PEG creatine, rather than against placebo. Source

Pre JYM Concerns:

  • Under-dosed, ineffective ingredients
  • Not suitable for most people
  • High in stimulants
  • Possible side effects
  • No money-back guarantee
  • Quite expensive

You will also find beta-alanine in each serving of Pre JYM. It is supposed to help by promoting recovery and reducing muscle soreness. It is thought that beta-alanine helps by increasing carnosine levels, but not many studies are there to confirm the claim. Moreover, many studies have found that beta-alanine may prove beneficial only when you take at least 5g a day. Unfortunately, you are only going to get 2g of beta-alanine from Pre JYM, which is not going to be enough. Similarly, betaine found in Pre JYM is not going to make a lot of difference because you can get enough of it through dietary sources. Supplements that contain betaine may also make your breath and sweat smell fishy. Alpha-GPC is also found in Pre JYM, which is supposed to increase focus and strength by increasing growth hormone. Some studies have found positive results, but the results are dose dependent. For instance, you may see results when you take up to 600mg of alpha GPC, but Pre JYM provides you with no more than 150mg per serving.

  • In seven men with at least two years of resistance training given 600mg Alpha-GPC 45 minutes prior to simulated bench throws, supplementation was associated with a greater exercise-induced growth hormone increase and 14% improved power output.

It contains a good dose of caffeine, which is a stimulant and is probably the reason why you may notice some improvement in concentration after taking Pre JYM. However, you should bear in mind that taking caffeine will not offer a lot in terms of muscle and strength gain. The effects are usually quite moderate, but there can be many side effects of taking high doses of caffeine. For instance:

  • Caffeine at doses of 3 mg/kg bw (equivalent to 210 mg for a 70-kg adult) ingested about one hour prior to endurance exercise appear to induce only a modest increase in body temperature compared to placebo. The Panel also notes that higher doses of caffeine (6 mg/kg bw 1569 equivalent to 420 mg for a 70-kg adult) ingested about one hour prior to prolonged endurance exercise in a hot environment do not affect body temperature or hydration status beyond what could be expected from the testing conditions.

Some supplement manufacturers say that caffeine may help reduce muscle soreness, but studies have found mixed results.

  • Muscle soreness during exercise. Evidence on the effect of caffeine for muscle soreness during exercise is inconsistent. It seems that taking moderate doses of caffeine (10 mg/kg) can reduce muscle pain during exercise, while lower doses may not have this effect.

You should also bear in mind that taking too much caffeine can lead to depression and other problems. For instance:

  • Some research suggests that caffeine intake is linked with an increased occurrence of depression symptoms in children. However, other research suggests that caffeinated coffee intake is linked to a decreased occurrence of depression in adults.

The fact of the matter is that Pre JYM does not provide you with enough of each ingredient, which is the biggest drawback of putting your money on this pre-workout supplement. It is available in different flavors, but most of them are not up to the mark. The price is on the higher side as well, which is another reason why you should avoid buying it in the first place. So, stay away from Pre JYM and look for something that provides you with right doses of scientifically proven ingredients to help improve your gains.

What Does Pre JYM Claim To Do?

Pre JYM is a pre-workout supplement and claims to help you in a variety of ways. Here are some of its claimed benefits:

  • Improves your energy levels
  • Helps you handle intense workouts with ease
  • Helps you have enhanced muscle strength
  • Improved focus and concentration
  • Supports faster recovery
  • Helps you enjoy better muscle pumps and growth

Does Pre JYM Work?

Pre JYM is designed to increase your strength, endurance, and muscle gain. Unfortunately, most of the ingredients in this pre-workout supplements lack scientific evidence for support. Some ingredients do have some scientific support, but they are quite under-dosed in Pre JYM. It contains beta-alanine, which is supposed to reduce fatigue and promote recovery, but studies show that you get these results when you take at least 5g of creatine a day. Pre JYM provides you with no more than 2g of creatine per serving. Similarly, you are not going to get enough of L-citrulline from each serving of Pre JYM. N-acetyl L-cysteine is another under-dosed ingredient found in this pre-workout supplement.

It does provide you with a large dose of caffeine, which may be the reason why you may notice an increase in concentration and focus, but caffeine works differently for different people, so be prepared to experience some side effects as well. Therefore, you should avoid putting your money on this supplement, and try something else with positive customer reviews and good scientific support.

What Are The Ingredients of Pre JYM?

Pre JYM contains a long list of ingredients, and while some of its ingredients are quite popular and somewhat effective, you do not get enough of those ingredients in each serving. It relies heavily on caffeine, which is why people who cannot tolerate this much of caffeine should avoid it. Here is what you will find in each serving of Pre JYM along with how those ingredient are supposed to help:

  • Citrulline malate 6g: To promote better muscle endurance and bigger muscle pumps.*
  • BCAAs 6g: In the 2:1:1 ratio best for blunting muscle fatigue, boosting muscle performance, and increasing muscle growth.*
  • Creatine HCL 2g: For greater strength, endurance, and muscle growth.*
  • CarnoSyn® beta-alanine 2g: To boost muscle power, strength, endurance, and muscle growth.*
  • Betaine 1.5g: For greater power and strength during workouts.*
  • N-acetyl L-cysteine 600mg: To support your body’s amino acid profile during exercise.*
  • Betavulgaris L.(beet) extract 500mg: To provide real nitric oxide donors for bigger pumps and better energy.*
  • Caffeine 300mg: To boost alertness and drive, increase muscle strength and endurance, during workouts for greater training intensity.*
  • AlphaSize® alpha-GPC 150mg: For better drive, focus, and strength in the gym.*
  • Huperzine A 50mcg: To increase mental focus and establish a stronger mind-muscle connection.*
  • BioPerine® 5 mg: To enhance absorption of nutrients for even better results.*
  • L-Tyrosine 1.5g: For sharper focus and drive during hard training sessions*
  • Taurine 1g: For enhanced muscle strength, endurance and nitric oxide*

Does Pre JYM Have Any Side Effects?

Pre JYM contains as many as 13 ingredients, and it is possible to develop several side effects when you start the use of this pre-workout supplement. You are likely to develop gastrointestinal side effects after using the supplement. Many people also complain about diarrhea and abdominal pain. You may also develop muscle cramps, which is usually the result of taking creatine. The presence of caffeine is the reason why many people are likely to deal with problems like insomnia, increased heart rate, depression, irritability, and stomach irritation.

Beta-alanine is generally considered safe, but many people may also develop flushing and tingling. Huperzine may also cause certain problems, such as sweating, slurred speech, blurred vision, loss of appetite, restlessness, twitching of muscle fibers, inability to control urination, increased saliva, frequent urination, and slowed heart rate. Side effects like fatigue, headaches, diarrhea, nausea, dizziness, and low blood pressure could also be due to the presence of alpha GPC.

Are There Any Customer Reviews For Pre JYM?

Pre JYM contains some popular ingredients, but it seems that it does not use those ingredients in right doses to produce good results. Customer reviews are pretty disappointing. For instance:

I have been taking this supplement for the last three weeks, but I have not noticed any change in my performance in the gym. I do not think it really does what it claims.

I have stopped using it, as it gave me serious headaches. I was also unable to sleep at night. I believe it could be due to high caffeine content. I am looking for something better now!

Does Pre JYM Offer a Money-Back Guarantee?
