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.



L-citrulline is an amino acid clinically proven to significantly decrease fatigue and muscle soreness while increasing nitric oxide, bloodflow, and arginine in the blood. Citrulline not only improves pumps and vascularity but also staves off intra-workout fatigue and facilitates post-workout recovery. Most preworkout supplements do not contain enough L-Citrulline to elicit its full-blown effect. CLASH contains a WHOPPING 6 GRAM DOSE for optimal results and the pump-enhancers don’t stop there…Agmatine Sulfate will be discussed later!

Creapure Creatine Monohydrate

The REAL German, patented form of Creatine, also known as “German Creatine”, CLASH is stacked with the full 5-gram dose of the real deal, not some cheap stuff. This is the creatine used in studies that deemed it to be perhaps the most effective natural supplement on the market, period. This creatine has been produced in Germany since the mid-1990s. Creapure®, manufactured by AlzChem AG, is the only creatine made in Germany. This creatine is known around the world for its high quality and purity, which is due to their careful selection of raw materials, technologically and patented system for synthesizing creatine.
  • Helps promote lean mass gains
  • Helps promote increased strength
  • Enhance muscle recovery
  • Helps improve anaerobic capacity

Carnosyn Beta Alanine

The REAL patented Beta Alanine demonstrated to have a significant impact on performance and strength gains, Beta-Alanine is important for Carnosine synthesis and is a pre-cursor to Carnosine. Carnosine is a buffering agent and by increasing the amount of Carnosine in the muscle, CarnoSyn® Beta-Alanine both helps increase an athlete's peak performance and helps speed muscle recovery. When supplemented, beta-alanine combines with naturally occurring Histidine to increase Carnosine in muscle more so than taking actual Carnosine.
  • Increased Peak Performance
  • Faster Muscle Recovery
  • Better Training Sessions with Better Results.

Betaine Anhydrous

Betaine Anhydrous, also known as trimethylglycine (TMG), has been shown to have affirmative results by helping to protect proteins, cells, enzymes and proteins from stresses such as dehydration and extreme temperatures. Betaine has been shown to have the ability to improve body composition quickly.

A six-week study showed that participants were able to lose 3% body fat while gaining over 5 pounds of lean mass while using Betaine; they also increased their power while bench pressing and their arm size increased during the study. Supplementation with Betaine has increased power, force and strength in bench press and squats; furthermore, the quality of reps performed and endurance with the squat exercise are also amplified with Betaine supplementation.

One reason Betaine is able to help your endurance and extend your workouts is by increasing both aerobic and anaerobic metabolisms. It may also increase performance during workouts by improving fatty acid and lactate metabolism - all while expanding intracellular volume. Cortisol levels have been lowered when using Betaine before exercising. Additionally, Betaine may have multiple mechanisms that increase nitric oxide blood levels to assist in the increase of vascular function.

Agmatine Sulfate

We have heard it all in the pump game. First was Arginine, which was promoted as a "Hemodilator" and "Vasodilator" and it HIT HARD and essentially started the preworkout category. We than found out through studies that it was all placebo and for Arginine to elicit any beneficial PUMP ACTION, it had to be dosed at ABOVE 10 grams preworkout and that could lead to stomach issues and also was impractical and well above what most companies put into their products.

Now we have a king, Agmatine. Agmatine is a byproduct of Arginine and at a much SMALLER dose of as low as 500mg you can elicit some great benefits, from pumps, to acting as a neurotransmitter (mental acuity), to removing metabolic waste. It does SO MUCH! Combined with the 6g of L-Citrulline, your pumps are going to be unreal!


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

Caffeine is the worlds most widely used stimulant. Caffeine is a Central Nervous System (CNS) stimulant that has been shown to reduce fatigue as well as mobilize fatty acids resulting in fat loss.


Teacrine is an energy and focus enhancer that does not make you CRASH after it hits you! This is the leader in sustained and intense energy, FULLY LOADED!

Teacrine boosts mental and physical energy, supports energy without jitters, irritability or habituation, supports a positive mood, increases motivation to exercise and improves focus and concentration.


Not only does this help decrease appetite, support energy and increase fat burning, it also acts as a vasodilator and diuretic. Theobromine can aid in fat loss and provide that extra bloodflow and PUMP. Theobromine has even been linked to having an aphrodisiac effect! All of this alongside a smooth, controlled stimulant release like caffeine make it a must!


We are all familiar with caffeine and how it increases energy and focus. There are additional benefits achieved from the use of caffeine when exercising. Almost everyone in the gym has taken advantage of this glorious substance to assist us at one time or another. Creative Compounds developed and produces a specialized form of caffeine named Infinergy, an ionic bond of caffeine and malic acid to increase energy and mental focus. Infinergy may also be easier on sensitive stomachs and is an excellent way to increase mental focus while supplying a surge of energy.

N-Methyl-L-Tyramine HCl and Hordenine HCl

These are added for their ability to stimulate mental focus and energy. Together, they are a potent combo!

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.

Clash is the best pre
Clash is the best pre workout out there. It's got the full clinically dose of each ingredient unlike any other brand, Marc and his team did not cheap out at all on this product! Gives you amazing pumps! 5 grams of creapure so you don't have to buy a creatine powder this has you covered so you save money! I had the pink lemonade it's got a great/refreshing taste and mixes great! There's no secret or useless ingredients witch is a plus so you know what you're taking, and doesn't have a mile long ingredient list with words you can't pronounce like most pre workouts. C4 isn't even in the same league as clash nothing can touch this product!! I recommend this product if your looking to feel like a machine in the gym!

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.

A shopper on Nov 25, 2015

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.
