It doesn’t matter if you’re just starting out on your fitness adventure or you’re a seasoned gym monkey, this Pre Jym pre-workout review will give you all the information you need to decide whether this is the right supplement for you!
Our Pre Jym review is based completely on what the science says about its ingredients and their doses and NOT what the manufacturer pitches to you in their marketing spiel!
That way we can help you cut through the bullshit and determine whether this product is actually going to do what it says or whether it’s just going to give you expensive piss! With an explanation of the intended role of each active ingredient, as well as the optimal dose according to science, rather than the brand, this is without doubt the most comprehensive Pre Jym pre-workout review on the web.
No more need for hours of research, no need to waste your time and money on pre-workouts which simply don’t help you. Our reviews have NO HIDDEN AGENDAS. We just give you the FACTS so that you can make up your own mind!
Ingredients in Pre Jym
The first thing to note about Jym pre-workout is that it doesn’t contain a single proprietary blend! This makes for a hugely positive start to our Pre Jym pre-workout review, and is something that should definitely NOT be underestimated when considering whether a pre-workout is a good option or not.
It means when you take a serving of Jym pre-workout, you know exactly how much of each active ingredient you are taking on board, which is exactly the way it should be!
Creatine HCL (2g)
The ultimate nutritional supplement on the market, creatine has some serious science to back up its benefits for exercise performance. Capable of increasing the number of sets and reps you are capable of in the gym and therefore allowing greater training adaptations in both muscle strength and size, creatine has become a staple supplement of most serious trainers.
Having said that, it must be dosed correctly in order to achieve those benefits. There are limited scientific studies involving the use of creatine HCL specifically with most research having been completed using creatine monohydrate. With creatine monohydrate the research indicates that a one week loading phase of 20g per day, in order to saturate muscle stores, followed by regular daily dose of 5g, is the most optimum protocol.
For creatine HCL, it has been suggested that this dose can be reduced to 1-2g per day. That means the Pre Jym dose of 2g per serving is bang on what is recommended. We must, however, highlight that this recommended dose is not supported by a wealth of scientific research like the 5g dose of creatine monohydrate.
Conclusion? Generally we would recommend taking a creatine supplement in monohydrate form simply because it is this formula on which the vast majority if not all of the research is based.
Beta alanine (2g)
Much like creatine, beta alanine is a particularly effective nutritional supplement capable of improving endurance and helping you to buffer lactic acid more efficiently.
Pre Jym, however, falls some way short of the optimal dose of 4-6g per day required for beta alanine to be most effective. Bummer! Having said that, 2g is far better than many other pre-workout supplements containing beta alanine so you could do a lot worse.
The bottom line, though, as far as this Pre Jym review is concerned, is that this is far from an optimal serving of a very effective ingredient.
Citrulline malate (6g)
Daaaammmnnn! That’s a whole lot of citrulline. Now we’re cooking.
Citrulline is included for one reason and one reason only, major muscle ‘pump’. By increasing the production of nitric oxide in the body, citrulline helps with vasodilation and in turn improves the flow of blood to working muscles. Winner!
Most studies agree that a daily dose of 6-8g is most effective at producing ergogenic results, which means that Jym pre-workout pretty much hits the nail on the head with its 6g dosage. Yaay, finally an effective supplement ingredient dosed at an optimal level.
Maybe this Pre Jym review is looking up after all!
BCAA (6g @ 2:1:1)
This Pre Jym pre-workout review seems to be finally moving in the right direction. BCAA’s or branch chain amino acids are a group of 3 amino acids (Leucine, Isoleucine and Valine) thought to improve endurance, reduce mental and physical fatigue and limit muscle soreness in the aftermath of intense activity. Sounds pretty useful to us!
Most studies seem to agree that BCAA’s should be consumed in a 2:1:1 ratio of Leucine: Isoleucine: Valine, which Pre Jym does. The recommended total dosage for optimum effect however seems to vary quite a bit, with most agreeing that between 5-20g has benefits.
Pre Jym contains a total of 6g, which means it certainly will be of benefit. There would be no harm, however, in it containing 2 or even 3 times the dose!
Caffeine anhydrous (300 mg)
A megadose of caffeine finishes the ingredients section of our Pre Jym pre-workout review on an incredibly positive note.
As one of the most ergogenically effective ingredients on the market when it comes to boosting energy and focus and helping users to increase fat metabolism, caffeine is a staple part of most pre-workout supplements.
At 300 mg, Pre Jym contains a little more than our preferred dose of 250 mg but who’s really complaining. Our only recommendation is that if you are new to the world of pre-workouts, or have particularly low caffeine tolerance levels, then it may be a good idea to start with a half serving of this product until you build up a bit of resistance.
So is Pre Jym any good or just hype?
Our Pre Jym review would have to conclude that this pre-workout is somewhere between the two. The use of creatine HCL rather than monohydrate and suboptimal dose of beta alanine is a real negative. Pre-workout products that get this right, however, are few and far between. Ergo… HYPE!
Having said that, the inclusion of significant doses of citrulline malate and caffeine, as well as a solid serving of BCAA’s do make this Jym pre-workout a very effective product. One which more than holds its own in the Wild West that is the world of nutritional supplements!
Pros and cons of Pre Jym pre-workout
Benefits of Pre Jym
The potential benefits of this Jym pre-workout are pretty far reaching.
Humongous doses of both citrulline malate and caffeine are major positives and should help users to achieve a significant muscle pump during sessions whilst also providing incredible mental focus and energy. Neither of which are to be taken lightly when it comes to finding a pre-workout to take your training to the next level.
Add in a solid dose of BCAA’s in the correct ratio and you also have a product which should help you increase muscle mass and will definitely help you to recover from tough gym sessions.
At $39.19 on bodybuilding.com Jym pre-workout comes in at around $1.30 per serving, which puts it at the more expensive end of the pre-workout market! Having said that, when you’re getting some of the most effective supplement ingredients at scientifically optimum doses you’re going to have to spend a little more money.
Given that there are plenty of pre-workout products available for similar prices, if not more expensive, that offer way less when it comes to ingredients, this seems like pretty good value for money in our eyes!
There’s only one word to sum up our Pre Jym pre-workout review and that’s ALMOST. The excellent quantities of citrulline malate and caffeine and solid dose of BCAA’s put this product way ahead of many of its contemporaries.
But, as seems to be the way when it comes to the most ergogenically effective supplements available, its dose of beta alanine falls way short of expectations. Add to that the inclusion of creatine HCL rather than monohydrate and things begin to unravel slightly.
At least, however, the refusal to hide serving information behind proprietary blends means that you know these key ingredients are underdosed.
This means that Jym pre-workout can be used in conjunction with other supplement products without the risk of overdoing certain ingredients. For instance, if you end up choosing Pre Jym, after all you’d be hard pushed to find a product packing such a pump inducing stimulant punch, then you can always supplement it with extra beta alanine and creatine from a pure source. This would be a great way of getting all the benefits of Pre Jym whilst also pushing those 2 ingredients in particular towards effective doses.
What is the best pre-workout supplement?
There are a whole range of nutritional supplements which can aid your training performance, and many of them are included in pre-workout products. That doesn’t, however, mean that they need to be consumed ‘pre-workout’ in order to be beneficial.
Creatine, and beta alanine, for instance are two of the most well researched and clinically effective supplements available when it comes to boosting training performance. Both are frequently included in pre-workout blends. Neither, however, need to be consumed before your workout in order to be effective.
What is important, however, is that both ingredients are consumed in adequate quantities and on a daily basis for an extended period of time.
Caffeine is another incredibly effective supplement, which does in fact need to be consumed ‘pre-workout’ in order to be effective. Most research suggests that taking up to 400 mg of caffeine between 30 and 60 mins prior to your session is safe. If, however, you have low tolerance to caffeine or you are taking caffeine as a supplement for the first time, then you may want to consider starting at a considerably lower dose in order to build your resistance.
What is the best creatine?
Creatine monohydrate is without doubt the most researched variety of creatine on the market. Almost all the scientific studies which support the ergogenic effects of creatine supplementation are based on creatine monohydrate.
Whilst other forms of creatine have hit the market in recent years, such as creatine HCL, there is very little research to suggest that it is any better at boosting training performance than its monohydrate counterpart.
