Delicious but thick and doesn't mix great

I could not believe the taste. I have a major sweet tooth and this almost tasted like I was eating cake batter so for the normal person, it might seem too sweet. It did not last 12 hours as far as filling, but that doesn't mean it wasn't working to help my muscles. This does not mix well, although I mixed mine with almond milk, so I can't attest for how it works in water. It tasted and felt like batter and there were some clumps. Overall though, I would almost come back to this one for the flavor alone because it's almost like a treat with its sweetness. Not to mention, low in sugar, less than 1 g per serving and a decen

Very Good!

This protein product was great! The chocolate taste was great. It was very easy to mix in a blender bottle with water. It also felt as if I ate a full meal right after I finished drinking it! Awesome product, will be ordering a larger supply =).

I liked it!

Product was a home run for me. Lean and delicious! Little bit of almond vanilla milk and it's a great lean shake with no bloat!

Great stuff

Very thick shake that fills you up. Tastes great mixed with anything. I have to really dilute mine in water for it to mix well but a great drink

Daniel M.

I took this after my workout and loved how it kept me going and feeling full and having to stuff my face immediately afterwards. Will for sure 100% apply this to my supplements, diet, and routine. The taste was thicker than i thought. Reminded me of brownies, but it was still good.


Sustained Release Micro-Feed Technology™

  • Fast, medium and slow release profile, ideal anytime- pre-workout, post-workout and before bedtime
  • Highest levels of the critical 5 amino acids (glutamine, arginine and BCAAs)
  • Flax, CLA and MCTs

PROBOLIC®-SR- 12-hour Sustained Release Bio-Efficient Protein
Probolic®-SR's patented 12-hour sustained release micro-feed technology and superior Critical Five Amino Acid Score (CFAAS) are major breakthroughs in protein supplementation. These two exclusive breakthroughs have set new standards in the bio-efficiency and anabolic effects of protein by giving you something no other protein can: a continual, 12-hour supply of the most critical amino acids to stimulate muscle growth, improve recovery and prevent catabolic muscle wasting.


Amino acids are the building blocks for muscle tissue. In order to achieve maximum muscle growth, you must have an adequate supply of amino acids to feed your muscles. Certain amino acids are more important than others for stimulating and supporting muscle growth. These amino acids are called the Critical Five amino acids which include glutamine, arginine, and the BCAAs (leucine, isoleucine and valine). PROBOLIC-SR's engineered protein matrix of whey concentrate, soy isolate and casein is precisely formulated to supply the absolute highest levels these Critical Five amino acids. Aside from providing the highest Critical Five Amino Acid Score, the protein matrix also provides a fast, medium and slow "release profile" which improves bio-availability and nitrogen retention.


The exclusive patented Sustained Release Micro-Feed technology further enhances the "release profile" and provides a continual supply of Critical Five amino acids for up to 12 hours. This controlled, sustained release of amino acids to your muscles increases bio-availability and nitrogen retention and creates the ideal anabolic/anti-catabolic state for maximum muscle growth and prevents muscle breakdown. PROBOLIC-SR's Micro-Feed technology makes it the most bio-efficient protein available.


Feed your muscles with PROBOLIC®-SR -- the 12-hour muscle feeder!
