MHP PROBOLIC-SR

SUSTAINED RELEASE MUSCLE FEEDING PROTEIN TECHNOLOGY FOR INCREASED MUSCLE GAINS!

PROBOLIC-SR’s research-proven protein blend of whey, soy and casein combined with its exclusive sustained-release micro-coating technology makes it a superior muscle-building protein supplement. PROBOLIC-SR’s protein sources and Microfeed Technology are designed to deliver a continuous supply of high levels of critical amino acids to stimulate muscle growth, prevent muscle loss and speed recovery. PROBOLIC-SR’s multi-phase release and steady supply of amino acids make it the ideal “anytime” protein. The fast-acting whey and long-lasting protein sources make it perfect for post-workout as it quickly and continually supplies amino acids.*

Man Holding Flavors

It’s also perfect to take in between meals to ensure you maintain adequate amino acids to decrease catabolic muscle breakdown and support muscle building. The Exclusive Sustained Release Micro-Feed Technology coating matrix used in PROBOLIC-SR further extends the supply of amino acids beyond 6 hours making the perfect nighttime protein. This controlled sustained release of amino acids to your muscles creates the ideal anabolic/anti-catabolic state for maximum muscle growth. Feed your hungry muscles with the most anabolic/anti-catabolic protein in existence, PROBOLIC-SR.*

PROBOLIC-SR’s PERFECT PROTEIN BLEND

Research shows that using the combination of proteins with different digestion rates whey (fast), soy (intermediate), and casein (slow) provides an extended duration of protein synthesis to enhance muscle growth and recovery.*

Fast, Medium & Slow Release

HIGH LEVELS OF CRITICAL AMINO ACIDS

PROBOLIC-SR provides high concentrations of the critical ­five amino acids (CFAAS) glutamine, arginine, and BCAAs (leucine, isoleucine, and valine) for enhanced muscle building. Plus, all the essential amino acids to ensure maximum anabolic muscle building and recovery. PRE-WORKOUT Muscle Feeder – During your workouts your body expends and depletes amino acids, so it’s critical you have an adequate supply. The whey protein in PROBOLIC-SR will give you the needed fast delivery of amino acids, while the slower digesting soy and casein will continue to supply and replenish key amino acids throughout your workout and for hours after your workout.*

High Levels of Critical 5 Amino Acids

SUPERIOR TO WHEY FOR POST-WORKOUT

While many athletes have relied exclusively on whey protein for post-workout recovery, many will be surprised to learn that while whey protein is good for igniting protein synthesis, it’s the least anti-catabolic of all proteins due to its fast, short-lasting supply of amino acids. Why is that important to know? Because muscle growth can only occur if your body has a continual supply of amino acids and retains more nitrogen (from protein) than your body loses through the ongoing process of nitrogen-turnover. This creates an anabolic state referred to as "positive nitrogen balance". On the contrary, without an adequate continual supply of protein (nitrogen), your body goes into a catabolic state of "negative nitrogen balance”, halting all hopes for muscle growth. If you train hard, you’re particularly at risk because heavyweight training leads to increased nitrogen loss and muscle breakdown. Probolic-SR is your insurance policy to staying in a positive nitrogen balance and experiencing unparalleled muscle growth.*

Sustained Release Micro-Feed Technology

NIGHTTIME GROWTH AND RECOVERY

During sleep is when your body builds and repairs muscle tissue. Sleeping the necessary 6 to 8 hours without being able to feed your muscles can create an unfavorable catabolic environment. PROBOLIC-SR’s exclusive sustained release technology continually feeds your muscles throughout the night to decrease muscle breakdown and help enhance muscle building and recovery.*

IDEAL FOR DIETERS

When dieting and restricting calories, you are vulnerable to going into a catabolic muscle wasting state. PROBOLIC-SR high levels for critical amino acids combined with its extended-release well help feed muscle tissue and prevent catabolism.*
