Probolic-SR’s patented 12 hour Sustained Release Micro-Feed Technology and superior Critical Five Amino Acid Score (CFAAS) have made this advanced supplement one of the most popular proteins on the market for years. The combination of this sustained release technology and the scientific balancing of enhanced CFAAS set a new standard in bio-efficiency and enhancing the anabolic effects of protein by giving you something no other protein can: A continual supply of the most critical amino acids including high levels of Glutamine†, Arginine and BCAAs for up to 12 hours to stimulate muscle growth, improve recovery and reduce catabolic muscle wasting.*

PROBOLIC-SR, the world’s first combination protein supplement of its kind, is formulated to provide fast, medium and slow releasing proteins in one advanced formula. The combination of these muscle building proteins provide for greater anabolic and anti-catabolic benefits than any other single protein supplement.*

Gym Tested, Research Proven

A recent landmark study confirms that consuming a blend of proteins as found in PROBOLIC-SR provides a fast releasing whey, medium releasing soy isolate and slow releasing casein, thereby supplying a prolonged delivery of amino acids to the muscles. This combination increases the “anabolic window” of muscle growth, making PROBOLIC-SR the superior protein for consumption following resistance exercise. If you’re looking for explosive muscular growth and maximum anabolic effects, you can count on PROBOLIC-SR!

*Combination Protein Enhances Post-Workout Muscle Building*
*Sustained Release Technology Fights Catabolic Muscle Loss At Night*
*Up To 12 Hours of Protein Feeding *


The results of a groundbreaking new research study suggest that a protein blend (a combination of whey, casein and soy) may be best to consume post-workout for building muscle. Specifically, the blend of proteins supported an increase in study subjects’ post-workout “anabolic window” (the amount of time it takes for building muscle to occur post-exercise). “This research study suggests that consuming a blend of proteins (soy, whey and casein) provides a prolonged delivery of amino acids to the muscles versus whey protein alone, making it optimal for consumption following resistance exercise,” said Dr. Blake Rasmussen of the University of Texas Medical Branch, who led the study.

It is well known that muscles don’t recover in 30 minutes post-workout. It takes at least 24-48 hours for your muscles to recover fully after resistance exercise. This clinical study suggests that protein blends can provide amino acid delivery for up to five hours, meaning if you consume a combination protein shake post-workout, the prolonged effect will deliver essential amino acids to help feed your muscles until your next meal.* This means that a combination protein blend such as that in PROBOLIC-SR may provide greater anabolic muscle building effects much longer than possible by using whey protein alone. It should also be noted that only Probolic-SR uses a patented Sustained Release Micro-Feed Technology to further extend amino acid release and anabolism.* To enhance its already powerful anabolic/anti-catabolic properties, only PROBOLIC-SR uses a patented Sustained Release Micro-Feed Technology to further extend amino acid release and anabolism for up to 12 hours.*

Patented Technology Increases Anabolic/Anti-Catabolic Effects for Enhanced Muscle Building!
*Patented Sustained Release Technology Feeds Muscle for up to 12 Hours*
*Superior Anabolic/Anti-Catabolic Matrix*
*Good Anytime: Morning, Pre- and Post-Workout and Nighttime
*High Levels of Glutamine, Arginine and Branched Chain Amino Acids – Known as The Critical Five Aminos

While many 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.

This advanced bio-engineered protein utilizes patented technologies to help 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.

When MHP launched Probolic-SR, it revolutionized the industry and became our new gold standard in protein supplementation. Probolic-SR’s bio-engineered protein was designed to exhibit high bio-availability, amino acid levels and nitrogen retention for maximum anabolic effects to trigger greater muscle growth. Probolic-SR contains a scientifically balanced bio-engineered matrix of high quality muscle building amino acids from the finest quality whey, soy and casein proteins, developed to provide extra amounts of the vital muscle building critical anabolic amino acids.*

Additionally, Probolic-SR takes a quantum leap beyond other proteins by employing a 4 stage, 12 hour sustained release Micro-Feed Technology. This patented advanced technology provides your muscles with a 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. Other companies 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 this proprietary technology exclusive to Probolic-SR and our legion of bodybuilders and athletes who rely on MHP to help them meet their muscle building goals.*

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 beyond other proteins.

Patented Micro-Feed Technology: The 12 Hour Muscle Feeder!
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 continually supply high concentrations of the Critical Five Amino Acids so that you can sustain an anabolic muscle building state and reduce catabolic muscle depletion. This technology helps achieve nitrogen-balancing modulation and also increases bio-availability.

Let us give you some information 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 gives consumers the impression that every gram ingested is utilized. NOT SO — our findings found that these values are based on relatively low dose consumption (only 9-18 grams of protein) and does not take into account the protein’s digestibility and absorption rate. 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 necessarily 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 can provide greater anabolic and anti-catabolic effects. Therefore, our research indicates that 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.

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. This unique 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 it’s medium and slower release (hours 2-6) will keep supplying aminos and help 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 help keep you anabolic all night! Probolic-SR will help ensure you don’t never slip into catabolism between meals, during workouts or during the night while you sleep and help keep you in “positive nitrogen balance” and anabolic overdrive!*
