Protein is an absolutely critical component to building muscle, without it or in inadequate amounts your body simply won't repair, recover nor grow! If you want muscle tone, add lean muscle mass and recover from hard training sessions as quickly as possible you need to use a high quality protein powder that will do all this and more for you.

Probolic 4 is an advanced whey based protein shake that also incorporates gradual release proteins to provide the ultimate protein formula for muscle growth. Applied nutrition have used a mix of whey protein isolate, concentrate and hydrolysed whey protein which offers you the best biological value whey proteins all in one shake!

In addition to whey protein, several other proteins which require more time to digest are present in each serving of probolic 4, providing a slow and steady release of amino acids into the bloodstream. Probolic 4 therefore offers you all the benefits of whey protein, a fast recovery rate and incredibly high biological value but combines this with the benefits of sustained release proteins making it a truly complete protein formula.

Probolic 4's ingredients ensure the maximum promotion of muscle growth and repair by constantly feeding your muscles with the all important nitrogen containing amino acids over prolonged periods.

Each serving of this excellent quality and good tasting purely protein shake provides 25g of protein as well as very low concentrations of fats and carbohydrates. These properties make probolic 4 by applied nutrition not just a great shake but possibly the greatest time release protein shake available today.
