MTS Nutrition Clash - Fully Loaded Preworkout

“I wanted to create the perfect supplement for ME! All science, all dosing, and with the perfect blend of intense and sustained energy. I want full dosing of scientific ingredients like Beta Alanine and Creatine in their purest, patented forms. I also wanted to be able to not worry about getting used to it and having to cycle my preworkout. With the anti-habituation effects of Teacrine, I can take CLASH every workout and still hit the intensity I need to make the gains I desire. This is CLASH, and all other preworkouts are hereby obsolete. THAT is not a game!”

-Marc Lobliner, CEO of MTS Nutrition


MTS Nutrition CLASH is where performance and improved body composition “CLASH”!

CLASH combines research-proven ingredients in a scientifically-validated, FULLY-DISCLOSED formula. It will not only propel you through the most grueling workouts, but also ensure you have all the ergogenic support you need to help build lean muscle and lose fat.



When in the gym, many individuals strive for an intense pump. The kind where it feels like your skin is going to tear. L-Citrulline can help you achieve such a pump. L-Citrulline has the ability to increase nitric oxide production, allowing your blood vessels to expand and dilate. This ingredient in itself has many benefits such as aiding in shuttling nutrients to the working muscles, promoting healthy energy levels, and improving blood flow. In addition, L-Citrulline can help prevent inflammation and muscle wasting due to oxidative stress (Ham et al., 2015). Supplementing with this ingredient has been proven to be safe and has also been used by patients suffering from erectile dysfunction as an alternative treatment method (Cormio et al., 2011).

Creapure Creatine Monohydrate

Creapure Creatine Monohydrate is known for its high quality and purity. Creatine (in general) is the most researched dietary supplement and ergogenic aid available on the market today. With hundreds of studies to back its effectiveness, many add this to their supplement regimen to give them greater performance during their workouts and quicker recovery time. Creatine also helps with building lean muscle mass (Tarnopolsky et al., 2008). In order to progress and see continued results, you need to consistently challenge your muscles. Creatine is capable of providing the working muscles with energy to allow you to push harder in the gym, all while helping to reduce muscle fatigue. It doesn’t just stop there. If creatine is added to a solid training protocol, individuals have the ability to improve their overall strength and body composition (Galvan et al., 2016).
  • Helps promote lean mass gains
  • Helps promote increased strength
  • Enhance muscle recovery
  • Helps improve anaerobic capacity

Carnosyn Beta Alanine

With over 55 studies on Carnosyn Beta Alanine, it’s hard to not want to add it to your arsenal of supplements. When muscle growth and strength are your goals, this is a must have ingredient in your formulation. Carnosyn has been shown to not only improve recovery time and muscle endurance (Smith et al., 2009), but also delay fatigue to allow you to push harder every workout (Derave et al., 2007). As a result of being able to increase your workload each workout, you can notice significant increases in overall muscle strength (Hoffman et al., 2006). Carnosyn Beta Alanine is so potent and beneficial, that it has been granted 14 global patents as a result.
  • Increased Peak Performance
  • Faster Muscle Recovery
  • Better Training Sessions with Better Results.

Betaine Anhydrous

Betaine Anhydrous, also known as trimethylglycine (TMG), is a component of beetroot. Supplementing with Betaine can help improve vasodilation by increasing nitric oxide levels in the blood (Iqbal et al., 2006). This can aid in providing a pump during exercise, as well as improving blood flow and nutrient transport. Betaine is also able to help improve endurance where more work is able to be completed prior to fatigue (Trepanowski et al., 2011). Additionally, when it comes to overall muscle growth and size, Betaine is able to support growth hormone levels by increasing IGF-1 in the body and was also found to reduce cortisol levels (Apicella et al., 2013).

Agmatine Sulfate

Familiar with L-Arginine? It’s used in many pre-workout products to aid in providing a pump/vasodilation. Agmatine, is a metabolite of L-Arginine and has many benefits which is why you can find Agmatine in many pre-workouts as well as nootropic supplements. Agmatine is great for mental functioning such as mental health, stress management, and mental clarity (Examine). Agmatine has the ability to aid in increasing insulin response which can improve body composition (Hwang et al., 2005). With the help of Agmatine, you can reduce perceived pain, allowing you to push harder and longer during workouts (Keynan et al., 2010). In order to build quality lean muscle mass, you also need to increase protein synthesis while shuttling nutrients to the muscles to help them rebuild and recover. Agmatine aids in regulating nitric oxide synthase to help produce nitric oxide which can then cause a vasodilation effect of the blood vessels to help transport nutrients throughout the body and into working muscles (Biolo, 1997). Another key benefit of Agmatine is it’s potential to affect testosterone levels. When there is a higher level of testosterone present, it primes the body to build muscle. Agmatine can also increase the secretion of luteinizing hormone, which is vital in testosterone production (Kalra et al., 1995).


N-Acetyl-L-Tyrosine is a more soluble form of the non-essential amino acid Tyrosine. N-Acetyl-L-Tyrosine can help with mental focus and cognitive function by increasing the levels of norepinephrine. This leads to better focus and mindset for the most intense training sessions.

Caffeine Anhydrous

One ingredient you will find in many pre-workouts on the market today is caffeine. This particular ingredient has been used to improve performance for more than 15 years – helping give athletes and the general population alike, the ability to improve their performance and increase their energy levels. While the dosages vary and are dependent on the individuals’ tolerance to simulants, the overall consensus is that caffeine can improve reaction time, logical reasoning, and vigilance (Kamimori et al., 2015). In addition, researchers have found that caffeine can also aid in enhancing long-term memory (Borota et al., 2014).


A hot new ingredient that is finding its way into pre-workouts is Teacrine and for good reason – it works. Teacrine is a great sustainable energy booster that doesn’t cause irritability, jitters, or the normal crash associated with many stimulants. Some other benefits to supplementing with Teacrine is its ability to heighten mental focus, improve mood, enhance motivation, and improves focus and concentration (Teacrine). Combine all of these benefits into one product and you have a powerhouse that has the ability to take your workouts to the next level.


Theobromine is commonly found in chocolate (cacao). The energy boost you get from chocolate is actually coming from Theobromine itself – dark chocolate having the highest concentrations. Along with the energy boost, expect to feel nootropic effects where you attain a feeling of relaxation (Mitchell et al., 2011). Due to the vasodilation properties found in Theobromine (Martinez-Pinilla et al., 2015), it can also help attain a pump during workouts. The dilation of blood vessels can help increase blood flow to working muscles as well as transport nutrients more easily throughout the body. In addition, Theobromine has a diuretic effect, pulling water out of the body (Eteng et al., 2006). Lastly, as an added bonus, Theobromine may help with weight reduction as well thanks to its ability to reduce hunger and help prevent overeating (Khazan et al., 2014).


This specifically formulated version of caffeine (di-caffeine malate) is an ionic bond of caffeine and malic acid which can increase mental focus and energy (Infinergy). In addition, Infinergy increases thermogenesis which can aid in weight loss. With this addition to any pre-workout and you can not only attain the energy needed to grind through the most grueling workout, but it can also help you burn fat and drop unwanted body weight.

N-Methyl-L-Tyramine HCl and Hordenine HCl

N-Methyl-L-Tyramine HCl (or NMT) is a great ingredient to add to any formula to enhance energy levels by utilizing fat and breaking it down into a usable energy source (Stohs et al., 2015). To enhance the effects from NMT, caffeine can be added to make the ingredient more potent. When placed in a pre-workout containing caffeine, N-Methyl-L-Tyramine HCl can help fuel intense workouts and send energy levels into orbit.

Closely related to tyramine, Hordenine HCl can help enhance muscular contractions (Barwell et al., 1989). This allows you to have intense contractions during resistance training, breaking down muscle fibers to be rebuilt stronger and larger. Hordenine HCl also has nootropic properties that can enhance mood and focus (Fisar et al., 2010). With Hordenine HCl’s ability to effect the adrenergic system, you can also find an increase in energy by boosting norepinephrine levels. In addition, supplementing with Hordenine HCl can aid in weight loss through increasing metabolism.

On the spot pre workout!
With my 9 years of lifting I have taken the following pre workouts,superpump 250, superpump max, no xplode, assault, c4, pre jym, nitraflex, k-otic, amino energy, platinum pre, n.o. shotgun, shock therapy, super charge, animal rage, animal pump, nano vapor, xpand, mr.hyde, 1.m.r., beta cret, beast mode, hemo rage black, black powder and annihilate. I might have left a few out but out of all that I have taken clash is hands down my fave. Clash has a full dose of creapure which is my favorite creatine and is topped off with carnosyn, agmatine,betaine and a great energy profile. Where other pre's have either not given me enough energy or too much where im zoned out, clash hits that sweet spot without losing sleep at night and the pumps are excellent! Strength, endurance, focus,energy and even elevated mood are exactly where I need them to be. The taste is exactly like natrual lemonade, very light and refreshing. This is my pre workout of choice from here on out.

I am pleased with the pre workout but only having 20 servings makes it a little inconvenient since I get my supps at the beginning of the month for the whole month.

Great results, but hard to drink
The new clash gives great energy, but can still sleep if I work out late in the evening. Pump was good enough that there is no need to take additional pump product with it. Great focus and endurance. Really is a complete package. Only downside was just how bad it tastes. It is very bitter and upsets my stomach a bit. I dont take these for the taste, but this is very hard to drink the way it is now. Will buy again if for sure if the taste improves.

does this have monohydrate creatine in it. Does this mean that I dont need to add that to suppliments?
sheryl s on Sep 13, 2013
BEST ANSWER: 5grams/2scoops

I would still recommend creatine on your off days, even post workout too.
Is it possible to counter effect the diuretic effects of the theobromine in Clash? I was very excited to start taking Clash, however the field bromine has... Destroyed my stomach for lack of a better term. I haven't taken it for about 2 weeks, and I'm running out of my back up pre-workout because I developed a tolerance and have to take more. I would like to go back to taking Clash, but if I'm going to shit through a keyhole every time I take it, I'm not going to be able to take it.
A shopper on Feb 5, 2018
BEST ANSWER: It isn't the theobromine, it is the stimulants stimulating your bowels. I would either lessen it to 1/2 scoop OR take with food OR sip it, don't slam it!
When will clash be back in stock?
A shopper on Jun 18, 2017
BEST ANSWER: Next week! New flavor too--APPLE!

Should I use clash on rest days?
A shopper on Mar 5, 2017
BEST ANSWER: I wouldn't as your body will get used to it and it won't be as effective when you actually need it in the gym... I would recommend you getting MTS creatine and taking that either daily or when your not taking clash as clash has creatine so you'll need to take 5G of that a day.
How many scoops can I take in 1 shaker? I did 1 scoop in 2 seperate days and Im not getting no energy sadly.
A shopper on Aug 16, 2017
BEST ANSWER: One scoop is the max dose. If you cannot fell CLASH you simply have built up a high tolerance to stimulants. Take 4-6 days off and then try it and you'll be happy!
I see this has monohydrate creatine. Can I still take creatine hcl? If so when is the best time to take it?
A shopper on Oct 28, 2016
BEST ANSWER: You could take HCL but I would take it after the workout as long as you were not taking it with MONO.
Marc, I lift m-w-f and sometimes sat every week. I only take clash on those days. I have been doing this for about a year. Clash seems to do great for me. Would it be beneficial to switch to ruckus for a jar then go back to clash in and vice verse to maintain the effectiveness of both products?
Jr2018 on May 8, 2018
BEST ANSWER: I like to use Ruckus on my chest and back days, Clash for other days, and I get MTS Creapure and Carnosyn Beta-alinine to stack with Ruckus to make it more complete.

Does this gives you that annoying itchy feeling like most Beta Alanine products do?
Demetrius B on Oct 15, 2013
BEST ANSWER: Hey Sir, Beta Alanine will cause parasthesis in very few individuals unless it is fake or underdosed. The good news is it subsides in 3-12 days.
I bought Vasky and i also want to buy this to pair them together. But i see that Clash already has creatine, sadly i had just bought micronized creatine powder. Can i still use it? Maybe use the clash and vasky for pre and the other creatine with a whey shake?
A shopper on Aug 2, 2018
BEST ANSWER: You can use the creatine on off days, or days you don't use CLASH. You only need 5g a day, so might as well save some $$
