Muscle Gauge 100% Pure Whey Protein Isolate:

The best tasting, cheapest pure whey protein isolate product on the market. Don't settle for whey protein blends when you can get pure isolate at these prices. 14 different flavors available.

2lbs - $17.99 | 5lbs - $31.99 | 10lbs - $59.99 | 25lbs - $124.99

Ever wonder what was a better protein source, whey or soy? Well, check this table out. I think this pretty much settles the whey vs. soy debate. I’ve always known that whey protein is the best form of protein available to us. I’ll also be posting a large comparison chart in a few weeks which will show whey protein vs pretty much every protein source there is! Keep an eye out for that one.

Soy Vs. Whey Protein Protein Type
Criteria Soy Protein Whey Protein Better Protein
Biological Value (BV) 74 104 Whey Protein
Net Protein Utilization (NPU) 61 92 Whey Protein
Protein Efficiency Ration (PER) 2.2 3.2 Whey Protein
Amino Acid Score (AAS) 0.99 1.14 Whey Protein
Protein Digestibility Corrected Amino Acid Score (PDCAAS) 1.00 1.00 Push
Protein Digestibility Percentage (PD%) 95% 99% Whey Protein
Glutamine per 100g of Protein 10.5g 4.9g Soy Protein
mg EAA per g of Protein 378mg 480mg Whey Protein
Arginine per 100g of Protein 7.6g 2.9g Soy Protein

As you can see whey protein wins on almost every count. The most important points you need to note from that table are biological value (BV) and amino acid score. These are the 2 most important factors that makes whey protein the ultimate product for lean muscle growth.

    why not mix whey protein powder into a ready to drink soy milk

    I m 38 years male, started a year back Gym, (weight lifting) my muscles are growing but not to satisfaction level.as I m vegetarian. Does to compensate the need one should eat nonveg or take supplements etc..other boys are taking the Supplements to grow…but Doctos says as it content Steroids it may affect on heart and other part may deteriotion.

    As i m auditor for ISO once visited a company making Soya Floor, grits ets. does Soya contain max Protein and will not have any adverse effect on health. They are also making toasted/untoasted foor, which is most helpful.

    please guide.

    Myth 1: Soy protein is not a complete protein.

    Fact: Soy protein is a complete protein.

    Soy Protein, has the essential amino acid profile perfect for human growth, development and maintenance as recognized by the Food and Agriculture Organization of the United Nations (FAO)/World Health Organization (WHO) – the scientific agencies on human nutrition and health worldwide.

    Myth 2: Soy protein does not have the key amino acids needed for muscle building.

    Fact: Soy protein contains all of the key or essential amino acids for muscle building, plus two amino acids known to stimulate growth hormone release and enhance immune function – Arginine and Glutamine.

    Soy Protein Isolate contains almost three times as much Arginine and almost twice as much Glutamine and higher concentration of naturally occurring BCAAs than whey protein, casein or egg.
    .
    Myth 3: Soy protein does not build muscle like whey.

    Fact: Soy protein is indeed a muscle-building protein.

    In fact, four clinical studies all demonstrate that soy protein is very effective in building lean muscle mass and got additional benefits of preserving two aspects of antioxidant function, indicating that soy protein can combat free radical formation during exercise, which may help speed muscle recovery after exercise.

    Myth 4: Soy protein is an inferior protein because its Protein Efficiency Ratio (PER) or Biological Value (BV) values are not as high as in whey.

    Fact: Soy protein is a high-quality protein comparable to whey protein, egg or beef protein.

    PER, BV and even NPU (Net Protein Utilization) are older measures of determining protein quality for humans. Alternatively, PDCAAS (Protein Digestibility Corrected Amino Acid Score) is the method recognized and implemented globally by regulatory agencies and health organizations, including the U.S. Food and Drug Administration (FDA) and the FAO/WHO, to determine protein quality of foods for human consumption. Isolated soy protein achieves a PDCAAS of 1.00, which is the highest & best in the ranking.

    Myth 5: Soy protein will lower my testosterone and increase estrogen.

    Fact: Soy protein does not affect either testosterone or estrogen concentrations.

    There is no scientific evidence that the consumption of soy protein to an altered testosterone level in men.
    In addition, data from Asian males who tend to consume high levels of soy have normal hormone levels and excellent fertility rates.

    Myth 6: Soy protein has feminine hormones that cause estrogenic effects.

    Fact: Soy protein does not contain estrogen or any other hormone nor does consuming soy protein have feminizing effects.

    When soy protein is consumed as the sole dietary protein source, and there is absolutely no sound and consistent scientific evidence in human subjects indicating that hormonal balance, body mass changes, or fertility are negatively altered by soy consumption.

    Myth 7: Soy protein is a woman’s protein.

    Fact: Research indicates that soy protein have several health benefits for men.

    Numerous studies reveal that eating a diet rich in soy protein has several heart health benefits. The significant body of evidence led the Food and Drug Administration to approve a heart health claim around soy protein in 1999. Additional studies link soy protein consumption to a reduced risk of prostate cancer. In fact, a meta-analysis of these studies indicate consumption of soy protein containing foods may reduce the risk of prostate cancer by 26%.

    Myth 8: Soy protein does not have the muscle recovery power as of whey.

    Fact: Soy protein contains natural bioactives that provide stronger recovery benefits compared to whey protein .

    Scientific evidence indicates that Soy protein produce stronger antioxidant effects than whey protein, which results in faster recovery..

    Myth 9: Soy protein is not as quickly digested and absorbed into the bloodstream as whey and therefore, is less effective than whey for building muscle.

    Fact: Soy protein is a highly digestible protein and is very effective for building muscle.

    Isolated soy protein is 98% digestible and soy protein has the highest PDCAAS (1.00) for a protein, which measures digestibility and availability of essential amino acids.

    Myth 10: Soy protein causes excess flatulence and disrupts the stomach.

    Fact: Soy protein isolate is gentle on the stomach and is formulated to not to cause the flatulence associated with whole soybeans.

    Soy protein isolate is processed into a highly digestible form. It has a digestibility value of 98%.

    Ok guys,
    First of all if you are a vegetarian you need to ppound soy or nut protein. The best way to build muscle is with whey because since it is a by-product of milk, it is naturaly made to help baby cows develop their muscles as they grow. It is the purest, rawest, most kickass muscle building block, and the most important. I’m on wheybolic 60 by GNC. That stuff is amazing. only 1gram fat per serving with 60grams pure whey protein. Plus about a dozen amino acids to help your body process it. Soy is protein that will get the job done, but whey is the best. Its like buying a chrysler or a rolls-royce.

    there is a wholeseller on ebay that sells soy around 3 dollars a pound of isolate. i cant think of the name. whey proteins are all over priced. its a rip off to pay 50 dollars for 5 pounds. on is about 8 dollars a pound.

    “Soy contains phytoestrogens known as isoflavones, which are plant-based compounds that have a similar function in the body as estrogen, says the University of Maryland Medical Center. Soy isoflavones appear to influence estrogen receptors and thus the effects of estrogen in your body.” – From Livestrong website

    Some muscle heads will say soy protein is basically the devil. The truth is yes you can gain muscle mass with soy protein but there are better alternative. I know some vegs won’t eat meat but will take whey protein. Others(vegans) won’t consume anything that is animal based, which one are you?
