Due to the bitterness of hydrolyzed whey protein, this product is not as smooth tasting as our Whey Protein Isolate and 100% Whey products. If taste is a concern for you, this might not be the right product.

*If the Chocolate flavor is too chocolaty, we suggest adding more water or milk.


Mix one serving (1 level scoop) with 6 to 8 ounces of water, milk or milk substitute, or beverage of your choice. Muscle Feast proteins will mix with just a few turns of a spoon, are free of "thickening agents", and are most importantly all natural. 

*Nutritional values vary slightly between flavors

Our hydrolyzed whey is not for beginners. Most hydrolyzed whey proteins are only hydrolyzed 2-5%, ours is hydrolyzed 12-15%; meaning it is further broken down, easier to digest, and more bitter than the average hydrolyzed whey protein. 

Does not contain any of the following:

  • Soy
  • Gluten
  • Additives
  • Added Sugars
  • Artificial Colors
  • Artificial Flavors
  • Unnecessary Fillers
  • Artificial Sweeteners
  • Heat or Chemically Treated Whey Protein Molecules

Whey Hydrolysate

What is it?

Whey hydrolysates are pre-digested proteins.  This means the long chains of amino acids typically found in isolates and concentrates are broken down into single amino acids.  Ultimately, this makes hydrolysates the fastest digesting protein source. Hydrolysates also enhance protein synthesis when combined with lower doses (less than 15 grams) of other forms of protein.

What does the research say?

A unique benefit of hydrolysates is they may decrease body fat compared to other forms of whey protein. Lockwood recently investigated the effects of an 8-week long study in which subjects received 30 grams of hydrolyzed whey or two varying forms of whey concentrates during a linear resistance training protocol. The results indicated that strength and lean body mass increased equally in all groups. However, fat mass decreased only in the hydrolyzed group.

Who is it best for?

Because hydrolysates have not been shown to be superior to isolates or concentrates in regard to muscular strength, hypertrophy, and recovery;  it may only be advantageous for individuals who are trying to build lean muscle mass while simultaneously trying to decrease fat mass.

How quickly does it digest/absorb and raise amino acid levels?

When consumed, whey hydrolysates elevate amino acid concentrations in the blood above baseline after ~10 minutes and peak out at ~30 minutes, followed by a gradual decline that can last up to 2 hours depending on the dose taken.

When is the best time to take it?

10 -15 minutes pre-workout, immediately post-work, or throughout the day/between meals to meet individual protein requirements.

I've been using the hydrolyzed whey for 2 weeks now post-recovery. It's been well-tolerated and is a good product!

Great tasting

My favorite protein powder. Grassfed and great taste.

Chocolate hydrolyzed whey

Very good protein powder that doesn’t upset my stomach.

Very good ingredients and a good price

The hydrolysed whey protein while a little bitter I have found it to be good and easily digestible. I did find the vanilla a little too sweet especially with Stevia however I will definitely buy the product again given its has very good amino acids profile

Great tasting, pure ingredients, good price

I've tried all of the MuscleFeast protein powders and this one is my favorite. It has the most protein per serving and mixes easily in water. While the taste might be bitter to some, I would describe it more as sour but not in a bad way. If you like sugary sweet protein powders then this one is probably not for you. But to me it is a plus not to have a protein powder that tastes like dessert or a candy. I love that there are no artificial ingredients. I highly recommend Hydrolyzed Whey Protein.
