MTS Nutrition Vasky Review

Vasky is MTS Nutrition’s stimulant free pre-workout which contains just four active ingredients: Taurine, Glycerol, Nitrosigine, and Vitamin C…

Taurine has been shown to reduce exercise-induced oxidative stress as well as slightly (but noticeably) enhance exercise performance in certain circumstances.  An often over-looked property of Taurine,however, is that it is an osmolyte (regulator of fluid inside cells).

It is similar, in this regard, to Betaine and Glycerol, and can increase cellular water intake, thereby promoting what bodybuilders refer to as “the pump”.

Vasky contains 3g of Taurine per serving, more than enough to provide the above-mentioned benefits.


As mentioned in the Taurine section, Glycerol is osmolytic, meaning it draws water into the cell. It is by this mechanism that Glycerol can preserve hydration status in the cell which explains why it has also been shown to enhance performance during extended exercise where dehydration would be a contributing factor.

So, as a performance enhancer, Glycerol may only induce noticeable enhancements during extended exercise (2 hours or more usually).  As a pump-agent, Glycerol can be quite effective and the 2g dose present in each serving of Vasky is more than enough to elicit noticeable effects (pumps).


Nitrosigine is a combination of Arginine and Silicon–stabilized with Inositol–which appears to be superior to other forms of Arginine.

A 2005 study noted that Arginine Silicate induced greater vasodilation and increase blood flow in mice, as compared to Arginine HCl

Similar results were achieved in a later (2007) study published in “Metabolism” and it was concluded that Arginine Silicate was more effective at raising plasma Arginine levels than Arginine HCl.

Vasky contains 1.5g of Nitrosigine, more than most Nitrosigine-containing pre-workouts.


Vitamin C has anti-oxidant properties which give it a variety of health implications.  In the context of Vasky, Vitamin C may support overall cardiovascular function, specifically by preventing the rapid degradation of Nitric Oxide which generally occurs in response to a stressor (such as exercise).

In this respect, it is similar to many other anti-oxidant compounds.


MTS Nutrition is clearly going for a simple, effective, and economical approach with Vasky. The fact that it’s unflavored indicates that it is intended to be added to other pre-workouts, reminiscent of Purus Labs Noxygen.   With only 4 primary ingredients, Vasky may seem under-developed to some, but given the highly effective doses of each key ingredient, it is actually quite effective for pumps.
