MTS Nutrition Vasky - Non-Stimulant Pump Inducing Preworkout

"When formulating Vasky™, we wanted a pleasant-tasting, yet unflavored non-stimulant pump enhancer that makes every preworkout better. Rather than fairy-dusting a bunch of redundant ingredients, we built Vasky off of two goals:
1) Improve bloodflow to the muscle.
2) Promote saturation of the muscles.

The proven dosing of trademarked and study-proven ingredients in Vasky give you all you need to achieve this. With Vasky's incredible value, it can easily be stacked with your favorite preworkout to achieve pumps and gains beyond your imagination. Are you Vasky?"
-Marc Lobliner, CEO of MTS Nutrition


MTS Nutrition VASKY™ is the SCIENTIFICALLY-DOSED leader in non-stimulant pre-workout meant to be taken as a standalone or with your favorite stimulant based pre-workout such as MTS Nutrition CLASH® or Ruckus™. VASKY contains Nitrosigine™ which enhances nitric oxide for an extended period of time, along with HydroMax™ Glycerol which promotes hyper-saturation of the muscles. With Taurine, added for its positive performance and volumizing effects, VASKY is guaranteed to help you achieve the greatest pumps and best workouts you’ve EVER had!


Being pumped beyond your wildest dreams... That's Not A Game!



The body uses the amino acid arginine to fuel nitric oxide production. For years, it was believed that supplementing with free from L-Arginine would increase blood levels of the amino acid, leading to improved NO production and greater pumps. Unfortunately, arginine carries with it an extremely poor bioavailability, rendering it essentially useless for increasing NO production.

Enter Nitrosigine, a “enhanced” form of arginine where the amino acid is bonded to silicate. Developed by Nutrition 21, Nitrosigine has been shown to elevate NO levels within 30 minutes of ingestion and keep levels elevated for up to six hours.[6] With daily usage, Nitrosigine builds up your baseline NO levels and keeps them elevated for up to 14 days![7]

Vasky includes the clinically backed dose of 1.5g of Nitrosigine, which has been shown to increase energy levels, muscle pumps, and recovery.[8]

Hydration is a critical component of optimal performance in and out of the gym. When adequately hydrated, you’re mentally and physically on top of your game. When you’re not, fatigue, both mentally and physically, rapidly set in.

That’s where HydroMax comes in. Pioneered by Glanbia Nutritionals, HydroMax is a high yield form of glycerol supplying 65% glycerol by mass. Glycerol transforms your muscles into ultra-absorbent sponges that allows them to soak up extra water, creating a state of “hyperhydration.” This creates massive cellular swelling, which aside from improved performance, makes for some pretty sick “water-based” pumps as well.[4,5]

Found in vast quantities in the brain, heart, and skeletal muscles, taurine is a semi conditional that provides multiple benefits to the hard-training athlete. First and foremost, taurine functions as a cell volumizer[1], encouraging your muscles to absorb extra water, which leads to improved hydration, stamina, and muscle fullness.[2] Since taurine is also present in the brain, it can enhance focus and reduce brain fatigue[3], helping you stay in the zone no matter how long you’re in the gym.

Vitamin C

An essential water-soluble vitamin, Vitamin C is most commonly associated with fighting the common cold. You might be surprised to learn it’s also a valuable performance enhancer and nitric oxide booster. Research has shown that the popular vitamin enhances nitric oxide synthesis, helping you look my vasky. On top of that, Vitamin C can also reduce fatigue and the rate of perceived exertion during exercise.[11]


"Great product that does what it claims! This pump is REAL!"

Been using it for a
Been using it for a couple weeks now and the pump is like nothing I've ever felt with other products. I personally mix it with Bpi 1.m.r Vortex. Which I will continue to do so. For the price you can't go wrong.
I did try 1 scoop of Vasky once due to not getting to the gym till late at night, and just want to add the "unflavored" taste is not that bad. It's like drinking sugar water.

finally a pre-workout without stimulants
I have to be careful of products since dealing with atrial fib and I have to stay away from any stimulants like caffeine which is in most pre workout supplements and I was so glad to find Vasky because it works so well for regular workouts and for pumping up before competition. Vasky will work for anyone if it works for a 65 year old competitor, thankyou MTS nutrition !!

If anyone is looking for a great pump product on a budget, this is it! Mix with a Gatorade or a coconut water and you are good to go! Gainz all day

I've been using vasky since it first came out , with no decline in effectiveness. I've never used a more powerful pump inducer . Honestly for me the effects off one scoop last all day , normal activities like holding the phone up to my ear or washing my face become difficult, because I actually start getting bicep pumps ! Same with my legs , back and chest ! Vasky is to say the least AWESOME !

Unbelievable pumps
Currently using pre Jym because super pump 3.0 was discontinued. I added Vasky and have to admit this combo is even better. The fullness factor of these 2 together is crazy because my pump sticks with me for hours afterwards.

Definitely a permanent pre in my list
***i bought this off of Muscle & Strength so it will probably say I didn't buy it*** I've taken a variety of Non-Stim pump inducers trust me, I have, but this one made it to the top of my list. Amazing pumps, literally all that there is to it. Just a crazy pumps. Especially with the massive dose of taurine in it. Your reps will keep on coming meaning a bigger pump. Now when it wears off, you can definitely feel it. Whatever body part you're working, it won't be as full or "pumped" anymore. this will also give you a great mind to muscle connection Because of the pump, and once you feel that pump, you WILL squeeze that muscle harder, you WILL demand that muscle is squeezed harder. Stacking this with any stimulant based pre workout WILL make your experience better!
Proof that I have Vasky :)

A shopper on Jul 8, 2015

davonte r on Jul 20, 2015

Could you stack it with Mr Hyde by pro supps?
A shopper on Jul 23, 2015
BEST ANSWER: Absolutely! I stack now with either Clash or Nitraflex (and throw some creatine in). It's a good add-on so you get a good pump, or it could be taken by itself.
Hello, I know it says you could stack it with stimulant based pre-workout, but would it be wise to stack this with Pre-Jym considering Pre-Jym has Taurine in it as well? Thanks
Jh R on Jun 30, 2015
I personally like to stack MTS Vasky with Taurine, Leucine & BCAAs before, during and after training for these reasons:
1. Decreased oxidative stress;
2. Increased energy;
3. Decreased muscle breakdown;
4. Increased muscle growth;
5. Decreased muscle soreness; and
6. Decreased body fat.
There are lots of studies on the effectiveness of these aminos.
Hope this helps.
Can you stack it with drop factor powder?
David S on Jun 27, 2015
BEST ANSWER: I have not but vaskey is non stimulant and has no flavor so I do not see a reason. Some might say Stimulants and dialtors don't mix cause they act in opposite direction but I see no reason you could not
Would this be okay to stack with C4 Ripped even though it is a fat burning pre-workout?
James B on Jun 26, 2015
BEST ANSWER: Yes it would be. In fact vasky is going to help keepthose muscle bellies full as ur going through your cut.(if you are)
You can pretty much stack it with any pwo since its a none stim product. I bought 2 tubs and love it. Some of the best muscle pumps. I like stacking vasky with agmatine and pwo of ur choice. I like c4 and assult.
How long before your workout should you take Vasky?

BEST ANSWER: Joshua - Yes , great for non stim . Especially if you train at night. Great product and awesome price with the latest ingredients for the pump. 5 out of 5 stars. ????????????
Does this effect heart health in anyway?
A shopper on Jul 7, 2015
BEST ANSWER: To be honest i am not 100% sure if it has effects on the health of the heart. I would think not becasue it is only four ingredients that are basicly already found within the body. It is also a non stim so is is not going to jack up your heart rate by itself. If you have a heart condition already, i would ask your doctor and just verify.
Is Vasky okay for women to take?
A shopper on Jan 17, 2016
BEST ANSWER: Yes my wife takes it all the time...of course if you have any major health concerns you shouldn't take it without consulting a doctor. But if you take regular pre-workout you should be fine.
Is there anyone experiencing diarrhea while taking this? I tried taking it with pre jym and I have awesome workouts but everytime after my post workout protein shake I have explosive diarrhea. I have always used MTS machine whey and never had problems so I know it's not the protein. I've taken pre jym alone as well with no issues. Any help would be appreciated.
A shopper on Nov 17, 2015
BEST ANSWER: Yes. It's the agmatine sulfate. Some people can tolerate more than others. Me? It give me the ability to poo thru the eye of a needle. It effects my ability to workout i.e. heavy deadlift just isn't safe... So I avoid it at all costs nowadays. After I removed it from my stack everything went back to normal.
can this replace a pre workout or is this to add to a pre workout?
A shopper on Oct 22, 2015

I took MTS Vasky alone and i didnt feel a difference in pump at or after the gym.. should i take two scoops next time?
Biggs on Mar 11, 2016
BEST ANSWER: You can double up on the dosage or go 1.5 scoops if needed. Try to really squeeze the muscle group. A change in how you do the reps can lead the a better pump. Found that more time under tension lead to a bigger pump versus just doing the reps (controlled).
Can you stack this with animal cuts and clash ?
Thaddeus on Feb 10, 2016
BEST ANSWER: Yes, cuts is a product you would take earlier in the day and clash is a pre-workout. Vasky has no stimulants in it which is what you would mix with clash for an enhanced pump at the gym
