 Pre JYM is the pre-workout formulated by JYM Supplement Science containing 13 active ingredients. It differs from certain other products in many respects. Some pre-workouts contain propriety blends under dosing critical ingredients, but with Pre JYM all of the ingredients are clinically dosed and fully transparent on the label.

There is a stamp of assurance with this product as you won’t be receiving a product that has been under-dosed. Some other pre-workout products only include a handful of ingredients or purposely omit certain ingredients due to cost issues.

Pre JYM differs in this respect as it contains 13 different ingredients to amplify your motivation before a workout. These include citrulline malate, the three branched chain amino acids- leucine, isoleucine and valine- creatine hydrochloride, CarnoSyn® beta-alanine, betaine (Trimethylglycine), l-tyrosine, taurine, n-acetyl l-cysteine, beta vulgaris L. (beet extract), choline bitartrate and caffeine anhydrous.


BCAA's: Taking BCAAs before a workout or any other form of exercise can help improve performance, especially for prolonged physical activity. Taking BCAAs in supplement form also provides the benefit of bypassing the liver and directly entering the bloodstream. This is different to any other source of BCAAs and is important to those looking to build muscle and minimise protein breakdown. Due to leucine being the most important of the three, Pre JYM provides a ratio of 2:1:1 of leucine, Iso-leucine and Valine and provides a total of 6g of BCAAs in total.

Creatine: The benefits of creatine have been extensively researched more than any other supplement ingredient and has been shown to increase muscle strength and muscle growth.Creatine is beneficial in exercise that contains short intense bouts- the gym being a prime example of this type of exercise. Creatine hydrochloride is used due to having a higher absorption rate of around 60% than creatine monohydrate. The most effective time to take creatine is before and after a workout, so taking Pre JYM will ensure you are maximising the effects of this incredibly popular ingredient among gym users and sports participants. Provides 2g of creatine HCL per serving.

Beta-alanine: Pre JYM also contains 2g of beta-alanine. This amino acid combines with the amino acid histidine to form carnosine. Research has demonstrated that this process can increase strength and power, improve recovery and endurance and even promote fat loss and muscle growth. When taken with creatine, beta alanine has been shown to have an enhanced effect as they both work synergistically with each other.

Betaine: Betaine has a host of benefits including the ability to improve muscle strength and power production and can increase protein synthesis at a dosage of 1g. One study on betaine found that it increased bench press power by 20% and muscle force on the bench press by 25%. Pre JYM provides 1.5g of betaine per serving.

Tyrosine: Tyrosine, a proteinogenic amino acid, is one of the amino acids used to synthesize proteins. This amino acid has also shown to support cognition during stress sensitive focus tasks. This provides additional mental support during prolonged exercise and can enhance focus and concentration. This preworkout is packed with a large dose of 1.5g of tyrosine per serving.

Beetroot Extract: Beta vulgaris (beet extract) is a growing ingredient in popularity for physical activity and endurance exercise as it has demonstrated ergogenic potential by reducing the o2 cost of physical activity allowing the body to take on a greater workload than normal. Pre JYM provides 500mg of beet extract per serving.

It also includes taurine which is important for endurance and muscle strength and nitric oxide production. When exercising, taurine is depleted compromising strength and endurance levels. It is therefore important to ensure there is sufficient amounts of taurine in the body before training. There is also 5mg of BioPerine® in Post JYM, a patented extract of the fruit of black pepper that contains piperine which can increase absorption rates by 30-2000%, in each serving of Pre JYM. It also contains 6g of citrulline malate, 350mg of choline bitartrate, 600mg of N-Acetyl L-Cysteine and 300mg of caffeine anhydrous- all ingredients that act as ergogenic aids.
