Current research shows that while whey protein has definite advantages, so do casein and soy proteins. But rather than making protein powder choices more confusing than ever for the bodybuilder, it's actually easier to ensure that you get the most from your protein powder. Just choose all three – whey, casein and soy protein powder – before and after workouts, between meals and any time that calls for a protein shake." – Muscle & Fitness

While independent sports nutrition experts and pro-bodybuilders agree that a combination of different proteins is better than whey alone, there is even more to the history-changing Probolic-SR protein breakthrough.
The latest sports nutrition research studies confirm how MHP was years ahead of the industry in the development of Probolic-SR. This advanced bio-engineered protein utilizes patented technologies to overcome protein’s natural limitations on nitrogen retention and muscle growth. Probolic-SR has set new standards in protein quality, bio-availability and anabolic and anti-catabolic muscle building power.

When MHP launched Probolic-SR, it revolutionized the industry and became the new gold standard in protein supplementation. PROBOLIC-SR’s bio-engineered protein was designed to exhibit the highest bio-availability, amino acid levels and nitrogen retention for maximum anabolic effects to trigger extreme muscle growth unlike any other protein. Probolic-SR contains a precisely balanced bio-engineered matrix of high quality muscle building amino acids from the finest quality whey, soy and casein proteins, with extra amounts of the vital muscle building critical anabolic amino acids.
Additionally, Probolic-SR takes a quantum leap beyond other proteins by employing a revolutionary 4 stage, 12 hour sustained release Micro-Feed Technology. This patented advanced technology provides your muscles with the most bio-efficient steady delivery of protein to trigger muscle growth and support recovery day and night. MHP’s unique Micro-Feed Technology is perhaps the biggest development ever in protein supplementation. This patented technology is so sophisticated and advanced that other supplement companies have virtually given up on trying to duplicate it, and have actually offered MHP large sums of money to relinquish this secret technology. But MHP isn’t interested in sharing our proprietary technology and we plan to keep it exclusive to Probolic-SR.
All told, Probolic-SR’s technological advancements make it an extraordinarily effective and powerful muscle building agent. Probolic-SR’s anabolic and anti-catabolic properties go far beyond any other proteins.
Overcoming Protein’s Limitations to Enhance Muscle Growth!

Protein’s limitations on achieving and maintaining the anabolic environment needed to augment large increases in muscle mass has remained a mystery to the scientific community. If a positive nitrogen balance (from protein) is the needed anabolic stimulus for muscle growth and if anabolic agents like steroids and HGH exert tremendous gains in muscle mass just by increasing nitrogen retention, then why doesn’t consuming large amounts of high quality proteins like whey, casein, soy and egg produce the expected gains in muscle mass? MHP’s senior research staff was determined to find out why these scientific principles of protein as a highly anabolic nitrogen source did not hold true once consumed.
During their massive research effort, MHP researchers analyzed every known natural source of protein for their Amino Acid Composition (AAC), Biological Value (BV), Protein Digestibility Correct Amino Acid Score (PDCAAS), Protein Efficiency Ratio (PER) and Rate of Absorption (RA)-the rate in which the protein releases amino acids. They also analyzed the amino acid composition of human muscle tissue and the effects of resistance training on nitrogen depletion and muscle tissue remodeling. Their research findings led them to the realization that:
• No single protein source in nature is capable of maintaining a positive nitrogen balance for exerting the desired anabolic effect for maximum muscle growth.
• No single protein source provides the adequate levels of key Critical Five Amino Acids (Glutamine, Arginine, Leucine, Isoleucine and Valine).
• Whey protein works best when combined with other proteins. While whey’s fast release rate is good for quick, post-workout replenishment, it’s not ideal for maintaining the maximum anabolic/anti-catabolic muscle building state. Whey combined with slower releasing proteins such as soy and casein is ideal for creating better anabolic/anti-catabolic effects.
• Specially manufactured soy isolates such as Supro® soy have many unique anabolic properties with great bio-availability (a perfect score of 100) and high levels of key amino acids such as glutamine, arginine and BCAAs. Also, noted is that contrary to false reports, soy does not increase estrogen levels. In fact, a recent double-blind clinical study compared the use of 4 different proteins: soy protein isolate, soy protein concentrate, whey blend (50/50 mixture of whey concentrate and whey protein isolate) and a soy/whey blend (50/50 mixture soy protein isolate and whey protein concentrate). The study concluded the effects of soy on the testosterone to estrogen (T:E) ratio were similar to whey!
• Casein’s slower release rate has better anabolic/anti-catabolic effects than whey to support muscle growth and recovery and is another protein that when combined with whey has even greater muscle building effects
The Scientific Breakthroughs Behind PROBOLIC-SR

With these findings, MHP researchers embarked on inventing the ultra-sophisticated PROBOLIC-SR formulation. The biggest challenges in bio-engineering a more powerful anabolic protein were altering the protein’s amino acid composition and controlling the release rate. It was evident that the only way to achieve the desired anabolic/anti-catabolic effects was to bio-engineer a protein utilizing a precise combination and ratio of various protein sources and employ a special time-released technology for optimal nitrogen balancing and modulation. After years of research and development, MHP was able to overcome these challenges and made two of the biggest breakthroughs in the history of protein product manufacturing: First, by bio-engineering an advanced protein matrix delivering the most complete profile of muscle building amino acids, highest in the Critical Five Amino Acids, setting new standards in amino acid scores; Second, the development of a patented sustained release delivery system, utilizing newly created MICRO-FEED TECHNOLOGY.
Setting New Standards in Amino Acid Scores

The World Health Organization and protein manufacturers use a method known as PDCAAS (Protein Digestibility Correct Amino Acid Score). Protein manufacturers have been using this method to determine the value of their proteins and many proteins such as whey, casein, soy and egg all have perfect scores of 100. However, MHP’s researchers detected two major flaws with this method relative to bodybuilders and muscle growth. The first flaw is that this score is based on pre-school children’s protein needs. We know that an adult bodybuilder’s protein needs are far greater than a pre-school child’s. Perhaps an even bigger flaw is that this score only takes into account essential amino acids and does not include the very important “conditionally essential” amino acids arginine and glutamine. From MHP’s extensive research on evaluating proteins and muscle tissues amino acid composition, it was determined that the five most important aminos for muscle growth in response to training are glutamine, arginine and the branched chain amino acids Leucine, Isoleucine and Valine. These amino acids provide the highest anabolic response and are needed to support muscle tissue remodeling in response to heavy training. These 5 amino acids are what the protein industry is now calling the Critical Five and they have established a new standard in measuring the value of a protein called the Critical Five Amino Acid Score (CFAAS). In the development of Probolic-SR, the MHP research staff developed a precisely formulated protein matrix of Whey, Supro Soy and Casein to provide high levels of essential amino acids and yield the highest possible levels of Critical Five Amino Acids. To get an even stronger anabolic response, MHP scientists further enhanced this matrix with even more free form glutamine, arginine, isoleucine, leucine and valine making Probolic-SR the most concentrated source of the Critical Five Amino Acids.
Patented Micro-Feed Technology: The 12 Hour Muscle Feeder!

The patented Micro-Feed Technology is the biggest breakthrough ever in protein supplementation. This pharmaceutical delivery system is designed to provide a continual supply of amino acids for up to 12 hours! The Micro-Feed Technology works similar to an IV drip continually supplying a “metered dose” of high concentrations of Critical Five Amino Acids so that you always stay in an extremely anabolic muscle building state and never slip into a catabolic state. This technology achieves nitrogen-balancing modulation and also increases bio-availability making full 100% utilization of every gram of protein.

To fully appreciate just how important this Micro-Feed Technology breakthrough is, let us fill you in on some of MHP’s findings regarding protein’s true Biological Value, utilization and ability to maintain a positive nitrogen balance. The protein industry and scientists have been using Biological Value (BV) as a measure of protein quality. Many proteins such as whey and whole egg are given a perfect score of 100, which suggests that every gram ingested is utilized. NOT SO—our findings found that these values are based on low dose consumption (only 9-18 grams of protein). When larger doses are taken, such as 40-60 grams, the amount commonly consumed by bodybuilders, not all of the protein is utilized. Some of it is converted to the waste products urea and ammonia, and can even be converted to body fat. This helps explain why large dose protein consumption doesn’t produce the desired anabolic effects you might expect. The research also found that the varying release rates of proteins influence their Biological Value, utilization and ability to supply nitrogen. While the whey industry has done a good job trying to lead you to believe faster is better in terms of release rates, new studies show that slower releasing proteins provide greater anabolic and anti-catabolic effects. Therefore, the ideal protein would provide fast, medium and slow release rates. It is important to realize that when it comes to building muscle, anti-catabolic properties are just as important as anabolic properties. In fact, most doctors and scientists credit the anti-catabolic effects of anabolic steroids to be more responsible for the gains in muscle than their anabolic effects.
Exclusive 4-Stage Release Makes Probolic-SR the “Anytime” Anabolic Protein

Due to Probolic-SR’s unique sustained release delivery system, it quickly became the protein supplement of choice for pre-workout and nighttime use. But Probolic-SR can be actually be used “anytime”, due to its exclusive 4-stage time-phased delivery system. The precisely formulated blend of proteins provides a fast, medium and slow release of Amino Acids and is further prolonged with the patented Micro-Feed Technology! This advanced release profile supplies the needed quick release (0-2 hours) of amino acids for post-workout replenishment of nitrogen. It is also perfect for pre-workout because its medium and slower release (hours 2-6) will keep supplying aminos and keep you in an anabolic state throughout your entire workout and prevent going into a catabolic state. It keeps delivering amino acids to your muscles for up to 12 hours. When taken before bedtime PROBOLIC-SR’s Micro-Feed Technology will supply high levels of the Critical Five Aminos and keep you anabolic all night! PROBOLIC-SR will ensure you never slip into catabolism between meals, during workouts or during the night while you sleep and always keep you in “positive nitrogen balance” and anabolic overdrive!
The Final Analysis: Probolic-SR is superior to other proteins!

PROBOLIC-SR is by far the most anabolic/anti-catabolic protein. It has literally changed the properties of protein and has made other types of proteins inferior and obsolete! To experience maximum gains, like Victor Martinez, make Probolic-SR part of your championship muscle building program.


What are the benefits of PROBOLIC-SR?

Maximizes muscle growth, speeds recovery and prevents catabolic muscle wasting by increasing protein synthesis and nitrogen retention.

How does it work?

Active Ingredients:

• Contains a 4 Stage Release Profile in order to continually feed muscle tissue for up to 12 hours:

Stage 1: Whey protein provides a high quality, fast releasing protein that feeds muscle tissue immediately and lasts for approximately 2 hours.

Stage 2: Supro® performance protein provides a high quality, medium speed releasing protein so you continue to supply your muscles with critical amino acids when whey is no longer found in the blood.

Stage 3: Casein protein: provides a high quality slow releasing protein so you continue to supply your muscles with critical amino acids when whey and Supro® performance protein are no longer found in the blood.

Stage 4: Patented Micro-Feed Sustained Release Technology microencapsulates a portion of the protein blend and slowly releases it into the blood over an unprecedented 12 hours. This ensures that muscle tissue is being fed the critical amino acids needed to maintain an anabolic muscle building environment for 12 straight hours.

• Contains the highest levels of the critical 5 amino acids – Glutamine, Arginine and BCAAs (Leucine, Isoleucine, Valine).

Glutamine: The most abundant amino acid found in muscle tissue, glutamine makes up approximately 60% of all muscle. Glutamine levels are rapidly depleted during exercise and if optimal levels are not in the body, muscle breakdown and loss will occur. Glutamine is known to promote anabolic conditions in muscle cells and increase the rate of protein synthesis, increase the cell volume of your muscles, aide in recovery, prevent muscle breakdown and spur the release of HGH.

BCAAs (Branched Chain Amino Acids: Leucine, Isoleucine and Valine): The next most abundant amino acids found in muscle tissue and make up approximately 33% of all muscle. BCAAs are heavily catabolized (broken down and used for energy) during exercise. If adequate amounts of BCAAs are not available during exercise, your body uses valuable muscle tissue for fuel. Unfortunately, the body cannot make its own BCAAs and there is a dramatic increase in the need for BCAAs for people working out. By maintaining optimal levels of BCAAs through supplementation, you can protect muscle, improve recovery and endurance and maximize muscle growth.

Arginine (Nitro loading): Increases Nitric Oxide production oxide, which is the muscle’s “cell-signaling” molecule responsible for blood flow (hemodilation), oxygen delivery, nutrient delivery and uptake (amino acids and glucose), muscle velocity, power output and muscle growth . The increased blood flow supplies more protein and nutrients to your muscles for increased size, fuller and thicker muscles, full body pumps, strength, vascularity and improved recovery. Arginine has also been shown to trigger HGH release.

Who should take it?

Anyone who is looking to maximize muscle growth, speed recovery and prevent catabolic muscle wasting by increasing protein synthesis and nitrogen retention.

How should I take it?

Mix 1-2 scoops with 8-16 oz of water. Mixes instantly in shaker bottle or glass. For a thicker shake, blend with ice for desired consistency.

Did you know?

Because of Probolic-SR’s unique fast-medium-slow and 12 hour extended release profile that it may be taken anytime – pre-workout, post-workout and before bedtime.
