WHAT IS SRO™ Zero Carb®?

†The All New SRO™ Zero Carb® — SpiroFuse Reverse Osmosis™

If you want a super-potent protein that contains no body fat promoting carbohydrates or fats, insist on ZERO CARB™ PROTEIN!

VPX® is proud to bring you a cutting edge NEW Whey Protein Isolate called, SpiroFuse Reverse Osmosis™ or SRO™! This invention is Whey Protein Isolate by Reverse Osmosis SpiroFuse Filtration™ or SRO™. Roughly 10 years ago VPX was the first company ever to release a ceramic filtered Whey Protein Isolate called cross flow microfiltration. This created quite a stir in the supplement industry because until that time, only whey protein concentrate (WPC) or low grade Ion Exchange WPI was available. As you can imagine there have been significant improvements in protein technology over the past 10 years. As a result of these superior scientific advancements, VPX is utilizing super high tech new membrane systems that produce isolated proteins that are 99% pure and are ultra rich in potent low molecular weight micro-fractions (LMWF). The SRO™ Zero Carb® flavoring system is also NEW and developed by VPX flavor experts solely for your enjoyment. These new SRO™ potent proteins and flavor technologies are only available inside SRO™ Zero Carb® Protein, Syngex® Protein and other VPX protein products. VPX is creating the future of muscle science, bodybuilding and performance enhancement to allow you to achieve your fitness goals!

The most consistent and effective way to lose weight and unwanted body fat is by consuming a high protein/low carbohydrate diet (with moderate dietary fat intake). This is primarily due to the fact that protein has a spectacular three-phase assault on body fat: 1) protein causes the body to release a hormone called glucagon that frees up stored body fat to be used as energy, 2) protein builds muscle tissue and fat is burned inside of the muscle cell; consequently, more muscle equals greater fat burning capacity, and 3) to digest protein, the body has to expend a great deal of heat: this process is called the "thermic effect" of protein and results in the body burning additional calories even at rest.

While it is true that one of the keys to losing weight is to expend more calories than we consume, the most important secret for long term fat and weight loss is to control the hormone insulin. Insulin release is consistent with the amount and/or type of carbohydrates we consume. This hormone also causes our body to store fat and can prevent stored body fat from being utilized as energy. However, if we control insulin with a low carbohydrate diet, we also reduce our body weight and body fat. SRO™ Zero Carb® Protein is the Carbohydrate-Free King of Proteins™ and can be utilized to supplement any type of low-carb diet. Many of the most successful weight loss programs have been based on low carbohydrate/high protein diets. Protein is unquestionably the single most important nutrient for dramatically redefining and improving your physique, and SRO™ Zero Carb® Protein is the highest quality fat and carbohydrate-free protein supplement available. Do what many of the greatest professional athletes, bodybuilders and movie stars have done and make VPX® an integral part of your supplementation program today!

solubilità eccezionale. zero residui gusto graham un poco di schiuma, ma non mi da nessun fastidio gusto fragola zero schiuma entrambi i gusti che ho provato sono ottimi e non troppo dolci. le proteine sono leggere e molto digeribili, non lasciano nessuna pesantezza di stomaco. riesco a prendere 120 gr di proteine al giorno senza nessun problema. il mio stomaco funziona benissimo.

I did not like this protein powder at all and had trouble taking it. The taste was not great but the worst part about it was that it does not dissolve well, even in a shaker bottle.

It's weird, this protein foams quite a bit when mixed with water. The graham cracker flavor is bad. It has a "weird" sweetness to it. It might taste better with milk but that pretty much defeats the purpose of this which is zero carb. Does this protein perform better than other proteins? Who knows, nobody knows. What I do know is that it's extremely expensive compared to other brands. Never again.

I don't have an enormous amount of experience with Whey Isolates so my review may be unfairly biased, but I just wasn't blown away by the vanilla dream flavor or the powder consistency. Looking forward to trying graham cracker next, fingers crossed for enhanced flavor.

I didn't like that protein at all. Tasted weird and mixed badly. Excellent value though.

I have tried a lot of different proteins due to my lactose intolerance. Since most proteins are Whey based, it is tough for me to enjoy a heavenly tasting protein shake. However, a rep on introduced me to this protein powder. It is absolutely fantastic and better yet it does NOT upset my stomach at all. I mix it with Chocolate Almond Milk and my PB2. It is heaven in a glass (or blender bottle).

Get on this program with VPX read the other reviews or call them they can help.

VPX Sports is amazing. Just one of the best Whey Protein Powder in the world! Good technology, good protein and good flavor. Especially Vanilla Flavor is the best Isolate Whey Protein taste in the world! Chocolate is good too, but, Vanilla is now my passion!

Graham cracker is absolutely delicious and you can't beat these ingredients. I personally would recommend it more if you're trying to keep your weight down/for females.

My first protein supplement. Taste is good nothing special. Immediate results. The wiffy notice my increase in size. My body is building muscle just as quickly as I did in high school 18 years ago. Taste great with almond milk, but water is just fine. I probably wont buy again... not sure. Looking at other options. ISOpure is the runner up. They stop selling this VPX ZERO carb in the Vitamin Store is the reason why I'm changing and they don't sale at GNC. Im not a numbers guy so im not sure how effective this product is. 5 years of laziness back in action im feeling a bit stronger.

*** Chocolate is too sweet, in a bad way! *** Vanilla tastes a bit awkward for me. *** Graham Cracker is just YUMMY!

It's definitely chocolate. Mixes well, taste is fine - nothing to really write home about. Purchased it for the ingredient profile, wasn't disappointed. Overall good quality, good taste, good value.

I've been fortunate enough to try all 3 flavors, and rotate between them to keep myself from getting bored. By far the best protein powder I've ever used, and will continue to use. The Graham Cracker is by far my favorite of the 3, and makes for an extremely tasty morning blender shake with some frozen strawberries!!!
