Athletic and Nutritional Information
The hydrolyzed whey protein 520 has the greatest potential to produce the best results for lean muscle mass. The small di and tri peptides produce the most dramatic pharmaceutical effects. The hydro 520 does not mix well with a spoon. A blender must be used for mixing. It has an extremely bad taste…One must NOT think that they can drink it straight. ProteinFactory.com® is the ONLY company to commercially market the Hydro 520 for anabolic use. The manufacturer of the Hydro 520 has confirmed this.

How to use the hydrolyzed whey protein 520 in your muscle-building arsenal.

If you want results from whey protein, if you are convinced, like we are, that whey peptides are absorbed much greater than regular whole food then you will try to fit the hydrolyzed 520 into your arsenal. The hydrolyzed 520 is one of the most unique whey proteins in the bodybuilding market. I say this because it is an extremely rare product. The larger nutrition companies are not going to use the hydro 520 because they sell to the mass market of bodybuilders. i.e. the general public who most of the time judges protein powders on taste only. How many times have you seen Designer Protein advertise how they won some gold medal taste award and how large manufacturers brag they win blind taste tests. Hydrolyzed 520 is a god awful tasting product. I remember my first experience with the “520” in that I dry heaved over my kitchen sink. I took a big gulp and “Blahhh”. I was like, “this is hydrolyzed whey protein.,how come this container on protein powder that claims to contain whey peptides tastes like a milk shake then”. I knew I had been had. Thus over the next few weeks I began to experiment with ways to drink some of the “520”. I found that by combining the 520 1 to 1 tablespoons with a regular whey protein I was able to tolerate the product.

Why is”520″ is so special?
Hydrolyzed 520 is an awesome product. Drinking the powder the peptides are actually by-passing the stomach and are being absorbed right through the small intestine and into the blood stream. Up to 80% of whey peptides can pass quickly through the stomach intact to be absorbed by the lower intestines. Small di-and tri-peptides are also absorbed faster than free-form amino acids. Regular whey protein has to be broken down into these peptides compared to the 520 which is already in a partial digestive state. What does this mean for muscle growth? The faster amino acids are absorbed, the faster protein synthesis can take place and an positive nitrogen state develops creating an anabolic condition.

How to use the 520
Buy the “520” and if you don’t have regular whey isolate or concentrate, get something like our CFM whey isolate or Heliogen Casein. Then add 1 to 2 tablespoons to your protein drink.

Tip:  Mix the hydro 520 with Peptopro

    It a great muscle builder and allows you to burn fat in the process. It is a little on the pricy side.It works great with good workout routine but it does cost a little more than the normal person can afford. Winter is here ad so are the holidays. So unless you are a fitness crazed person or bodybuilder the price can be steep.

    Can't beat the 520The 520 is by far the best protein on the market. As it is super fast acting, I use it in my morning shake and post workout. When it's sold out and I have to go with another protein for a few weeks to a month I can really notice the difference. I now buy at least 7 bags at a time :)

    Approved by Team Muscle IntelligenceAfter a very long and frustrating research to find a high quality whey hydrolysate, we have finally found Alex and protein factory with the HYDRO 520. This is the only hydrolyzed whey we could find with a guaranteed high di- and tripeptide content, which in the end is the only reason to buy a protein hydrolysate. Recovery is fantastic and muscle soak up glucose like crazy when high amount of peptides are co-ingested with carbs.

    A 50/50 Blend of this protein and Peptopro alongside with a high molecular weight carbohydrate like Vitargo is what all our athletes at Team Muscle Intelligence are advised to take post workout.

    Hydro 520I hope 520 works just as reasearch says, cause it is bitter like Alex warned. No problem mixing and slamming down post workout protein blend.

    Most Effective Protein that I have ever used....Take a half a scoop of this protein with a half scoop of Isolate, and you will actually immediately feel it. It has been one of reasons that I have grown so much. I have been taking it since the Protein Factory came out with it.

    Dont act like a 5yr old man up try this stuffOk got this when peptpro was out of stock and it is great bang for buck , really if you are not 5yrs old Man up it doesn't taste that bad, I do mix in blender , not sure if shaker bottle will do it. I swear I'm feeling some gains on this. Recently I had some leucine powder super nasty and egg peptides laying around and mixed it all with the 520 - it is very doable , either add chocolate or lemon extract , glucose and or stevia gulp it down.

    Hydrolyzed Whey 520!Great for intra and post workout. I mix it with coconut water but sometimes I just drink it straight. It's not nearly as bad as a lot of people make it out to be. I drink protein shakes for the recovery and amino benefits, not to get my chocolate sundae cheat fix! This stuff mixes just fine in a shaker bottle.

    best post-workout proteinThe post-workout window is the most important time for nutriant intake. I pair hydro 520 with rilose and leucine. I've gained 5 lbs in the past 4 mounths!

    Hydrolyzed 520 Whey Protein reviewAfter a few days taking Hydrolyzed 520 (vanilla flavor) post workout, I noticed an increase in anabolism. The muscle group that I trained felt fuller and more recovered compared to having trained the same muscle group in weeks prior without consuming a serving of Hydrolyzed 520 immediately after training. Moreover, I noticed an increase in strength with consistent use of Hydrolyzed 520 (post workout). Although this seems like a great protein, consumers should note that this protein is quite bitter and not pleasant tasting by itself. The bitter taste can be subdued by various remedies such as adding a banana and strawberries (my fav combo) to the shake with just a dab of chocolate syrup. I can’t wait to continue with this product for a month or more once I’m able to train on a regular basis. Thank you, Alex, for making a great protein.

    Excellent post-workout whey protein!Hydro 520 mixes extremely well and does not leave you bloated. The taste is very bitter; however, I found that combining this with Oat Muscle eliminates the bitter flavor.

    Best There IsThis stuff isn't for the beginner, or even the intermediate. This is the real deal, it taste bad, but that's not the point is it? If you are looking for protein that taste good you have lots of choices. But if you are working for protein to take you to the next level, there is only one choice.
