Power Block Pro XXX-LG by Physical Sciences Big muscles require the best in nutritional supplements. Protein and carbohydrates are the two key factors in developing your physique to the best it can be. Not just any protein or carbs will do if you want to resemble a Greek god or be as strong as one. You need top of the line, and Physical-Sciences Powerblock Pro XXXL is just that. Packed with 50 grams of high-quality protein and a matching 50 grams of muscle-fueling carbohydrates, this 400 calorie per serving nutritional juggernaut gives your muscles exactly what they want.

To begin with for Physical-Sciences Powerblock Pro XXXL formula, we have gone with whey protein isolate. Whey protein isolate has a biological value of 159 as well as the highest bioavailabilty rating of any protein food substance. Combine that with an absorption rate of between 93% and 98%, and you’ve got a protein that is almost completely utilized. That means less protein is wasted and more is utilized for muscle growth.

Physical Sciences also uses hydrolyzed lactalbumin, which, similar to hydrolyzed whey protein, has been specially prepared through an enzymatic process, leading to a much quicker and greater absorption rate. Hydrolyzed lactalbumin provides a rich source of short-chain peptides and amino acids in a state of pre-digestion that leads to much greater absorption. Again, this means less is wasted and more is used to stimulate muscle growth.

In each 400 calorie serving of Physical-Sciences Powerblock Pro XXXL, you get 50 grams of quality carbohydrates from grains and dextrose. These two carbohydrate sources provide you with slow- and fast-digesting carbs, to quickly replenish glycogen levels and then to supply a steady stream of carbohydrates to help fuel your body throughout the day.

Leucine is the major amino acid responsible for the anabolic effects of a meal and the addition of leucine to meals and/or protein shakes can increase protein synthesis by 50 to 70%. It is because of this that we have added 10 grams of leucine per serving to Powerblock Pro XXXL. That means more of the protein ingested is used to build muscle. Just imagine how much faster you will be able to build quality muscle mass when you have increased protein absorption by 70%!

Recovering from your grueling workouts has never been easier thanks to Physical-Sciences Powerblock Pro XXXL. With the high-quality protein and carbohydrates, as well as the additional leucine, your muscles will recover more quickly so you can get right back to pushing them again to their limits. Train hard and supplement smart. You do the hard training, Physical-Sciences provides the smart supplementation.

BUILDING BLOCKS SERIES This series of products will concentrate on providing the user with the highest ratio’s of the highest quality muscle building and enhancing compounds being produced in the world today. Our Power Block Pro XXX-LG product was formulated to be the most powerful pre and post exercise nutritional supplement in existence. Beginning with the release of insulin which has been correlated with many anabolic properties involved with tissue building. Insulin has been proven to stimulate protein synthesis and inhibit protein breakdown when administered both during and post-exercise. The supplementation of a carbohydrate, protein hydrolysis, and leucine mixture taken during exercise, it was demonstrated that this mixture leads to greater increases in skeletal muscle hypertrophy and strength. Once believed that insulin secretion was controlled almost entirely by blood glucose concentration. It's since become apparent that amino acids play a crucial role in the regulation of insulin secretion. Certain amino acids have been shown to cause insulin release in humans, even under conditions where blood sugar levels are normal. In order for most amino acids to effectively stimulate pancreatic beta cell insulin release, permissive levels of blood glucose must be present. L-leucine is an exception, as it's the only amino acid capable of increasing circulating insulin levels regardless of blood glucose concentration. The increase of insulin has been shown to decrease the rate of muscle protein degradation. By limiting protein degradation, leucine may allow for a net protein synthesis post-resistance exercise, leading to greater muscle hypertrophy. Essentially, this insulin response will provide an environment that promotes tissue building, as opposed to tissue breakdown. 221% greater insulin response will be achieved by ingested a high glycolic carbohydrates with protein hydrolysate and leucine as opposed to carbohydrate alone. Ingesting carbohydrates with protein hydrolysate, but without leucine, only a 66% greater insulin response was observed than with carbohydrate alone. L-leucine supplementation is beneficial to resistance exercise in terms of its ability to modulate insulin signaling. Post-exercise hyperinsulinaemia (high insulin) supported by hyperaminoacidaemia (high amino acids) induced by protein hydrolysate and leucine ingestion increases net protein deposition in muscle, leading to increased skeletal muscle hypertrophy and strength. During and post-exercise, it's ideal to ingest a fast-digesting drink of hydrolyzed protein, sugary carbohydrates, and leucine because of the combined high blood insulin and high blood amino acid concentrations that accompany such a drink. Based on research, this type of drink doesn't only work through the modulation of insulin release. Leucine helps grow muscle because it's also a key element in the activation of translational pathways responsible for muscle growth. This product is the top choice for individuals demanding optimal performance from their nutritional supplements as they do of themselves.


Hydrolyzed Whey Isolate
Hydrolyzed Lactalbumin
Dextrose (glucose)
(50g of protein per serving)

HYDROLYZED WHEY ISOLATE The most digestible whey protein for human consumption. Hydrolyzed whey is a whey protein isolate that has some of its amino acid peptide bonds broken enzymatically into shorter chains of amino acids, leading to much greater protein absorption. Whey proteins produce a dramatic but short increase in plasma amino acids.

HYDROLYZED LACTALBUMIN lactalbumin and -lactoglobulin are the major proteins in whey. Hydrolyzed lactoalbumin is a specially prepared enzymatic digest of lactalbumin. It provides a rich source of short chain peptides and amino acids. By breaking the peptide bonds enzymatically into shorter chains of amino acids leaving the protein in a state of digestion leading to much greater protein absorption.

DEXTROSE Better known today as glucose, this sugar is the chief source of energy in the body. Glucose is chemically considered a simple sugar. It is the main sugar that the body manufactures. The body makes glucose from all three elements of food, protein, fat and carbohydrates, but in largest part from carbohydrates. Glucose serves as the major source of energy for living cells. Dextrose (glucose) is a monosaccharide (basic unit of carbohydrates, C6H1206) and has a high glycemic index (digested carbohydrates ability to raise blood glucose levels, also called Gl) ranking at 100.

MALTODEXTRIN is a sweat, easily digested carbohydrate made from cornstarch. The starch is cooked, and then acid and/or enzymes (a process similar to that used by the body to digest carbohydrates) are used to break the starch into smaller chains (3-20 chains in maltodextrin). These chains are composed of several dextrose molecules held together by very weak hydrogen bonds. Dextrose is labeled a simple carbohydrate and Maltodextrin complex. Maltodextrin is a Polysaccharide which are polymeric carbohydrate structures, formed of repeating units (either mono- or di-saccharides) joined together by glycosidic bonds.The bonds that compose maltodextrin are very weak, and readily broken apart in your stomach; moreover, the chain is extremely minimal in composition. The weak bonds, and fragile composition of maltodextrin cause it to be digested a fraction slower than dextrose. The negative effects of intense physical activity become greatly reduced when a drink contains a glucose polymer stacked with dextrose. However, a carbohydrate that is easily digested, and has a high Gl is still desired. Hence, a combination of dextrose and maltodextrin is advised. Osmolarity will be decreased, and glucose will still enter the blood stream at a proficient rate, thus maintaining its anabolic nature.

L-LEUCINE An essential amino acid which means that humans cannot synthesize it from other compounds; it must be ingested from sources. C4H9CH(NH2)COOH, obtained by the hydrolysis of protein by pancreatic enzymes during digestion and necessary for optimal growth in infants and children and for the maintenance of nitrogen balance and muscle protein synthesis in adults.

HOW LEUCINE WORKS leucine is unique in that once absorbed it travels directly to muscle tissue where it acts as a signal for protein synthesis. How does it signal protein synthesis? Well, without getting too technical, leucine activates a special component of a muscle building metabolic pathway, called mTOR. Try to think of mTOR as the amino acid sensor in cells and know that it is sensitive to the presence of leucine. As leucine concentrations increase in muscle cells, mTOR knows there is sufficient protein available to make new muscle protein.
