Bodybuilding and Athletic Supplementation Description
The hydrolyzed 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.comŽis the ONLY company to commercially market the Hydro 520 for anabolic use. The manufacturer of the Hydro 520 has confirmed this. If one chooses to use the hydrolyzed 520 whey protein in a custom protein mix, try to keep the percentage 25% or lower.

How to use the hydrolyzed whey 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 supplement 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 supplement 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 manufacteurers 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?
Hydrolzed 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" separately, get 1 or 2 pound plain unflavored and unsweetened. If you don't have regular whey isolate or concentrate get some then add 1 to 2 tablespoons to your protein drink.

    Great product for quality and purity! Don't mix it with anything less than 1 part to 3 parts of something else that can have sweeteners added. It tastes like shit by itself...beware.
  • Author: chadschippers@hotmail.com
    I love the fact that PF has this by itself. This product tastes awful by itself but you can mask it if you can't handle it. Buying this stuff by itself is certainly cheaper than Beverly protein that contains the hydrolized protein but is so much more expensive. You can ensure how much you are getting and add what you want to it. Top notch stuff for bodybuilders looking to gain lean muscle.
  • Author: bruton@hawaii.rr.com
    I love the stuff and I don't find it that bad at all. A small amout of chocolate hides the taste if the water is real cold.
    A little instant coffee hides it too. It is lightning fast stuff.
    WPI mellows it out also.
  • Author: geoffgarcia@hotmail.com
    I've taken the 520 hydro with water and nothing else several times.
    Its truly disgusting.

    Mixing it 50/50 with CFM is...well its still disgusting...
    Mixing it 33/33/33 with dextrose or maltodextrin doesn't help...(I get all my supps unflavored and unsweetend)

    I'll continue to order it and take it in this fashion...who knows...maybe one day I'll get some kinda pavlovian effect where my muscles will just respond when I drink it:)

    if I was looking for a candy bar I'd go with a whatchamacalit
    but I'm looking to gain lean muscle and the molecular content of hydro 520 is good, so I'll stick with it...
  • Author: sauction@gmail.com
    I have tasted many things in my life - many things - and this stuff is BY FAR, the worst tasting thing on the face of this earth in the history of all mankind. I would not even feed it to my dog - in fact I would prefer dog food over this any day. This is not an understatement. I don't care how good this stuff is supposed to be - it can't be much better than good 'ol whey. Unfortunately, the only thing I have found this to be good for is letting friends take a whiff of this stuff and then daring the brave ones to drink a glassful of it without holding their nose or puking.

    Proteinfactory.com response by Alex Rogers.
    Yes, I would agree this is the worst tasting protein on the planet. But I would have to disagree with your comment on "it cant be much better than good 'ol whey. If I could explain the bad taste that you are experiencing is the actual whey peptides. The hydrolyzed 520 is probably the highest quality whey peptide made. Thus it makes it perfect for post-workout. Remember, the faster you shuttle amino acids into the blood stream the better your chances are for muscle growth. I would recommend that only hard-core bodybuilders use the 520 and/or people who dont care about taste. But I'm glad you let us know about the taste. We have alot of beginners trying to use the 520. You can still use the 520. If you combine it with dextrose and lemon/lime gatorade and/or grape flavor that will help with the flavor.

    I'm a Canadian Customer that's been buying from Protein Factory for quite sometime now. Products are awsome, price is unbeatable even with shipping and exchange rates.
    My favorite customized product is as following:
    30% Soy Isolate
    40% WPC
    10%Flax Powder
    10% Yolk Powder
    10% Dextrose.
    Taste great, easy to mix and provide my body with a boatload of protein. 2-3 shakes/day, and I'm good to go..

    Out of all the supplements/proteins/foods I have tried I believe hydrolyzed 520 has given me the best consistent gains. Hydro 520 is so fast absorbing I take large sips while working out with out getting cramps. I have been ordering it now for two years and have had incredible natural gains. I can't believe so many people complain about the taste... they have obviously never tried glutamine peptides. If you make it chocolate you will not taste the hydro. You are going to want to add hi GI carbs to hydro 520. I go 50/50 carbs/protein. You may want more carbs if you can handle them. DRINK IT WHILE YOU WORK OUT. Then 30-60 minutes post workout have whey/casein with some low glycemic carbs. This will maximize your utility of the anabolic window w/o carb spill over while giving you an insuline spike when you need it most.

    I've given this a high rating but only because I can stomach this protein.
    A lot of people complain about the flavor... but fair play to them if they don't like something because of it's flavor. Just remember and old saying "Things that are good for the body are usually bitter." Going along the same lines, the more benefit, the more bitter the taste.

    So with that I say that I've tried Peptides of all sorts and they all taste "Bitter." But I've also noticed a large difference in my body when I use them. I nearly choked the first time I drank glutamine peptides in my during workout shake (Glutamine peptides and Theta Aminos). After the first time it was no problem. 520 is no exception.

    I drink it in a three part mix. 1/3 Hydro 1/3 CFM 1/3 HRS. It tastes like drinking plastic. It also keeps the annoying gym rats away because of the smell of it when I drink it. (Another bonus)

    I do recover a lot faster and I also am getting some better size on now so I'm not complaining about the taste. If it ain't broke don't fix it. Since this seems to be working well... I guess I'll be drinking plastic for quite a while.

    5 Stars if you can handle it.

    What's the big deal? So on it's own it tastes bad....so, don't be silly and try to drink it on its own.

    35% hydro, 35% dextrose, and 30% maltodextrin, plus some spenda with the chocolate flavor option and it actually tastes okay--in fact, I LIKE it. No, it's not a "rich creamy shake" but with cold water it's decent tasting. But the real plus is that post-workout with a little glutamine peptide thrown in (10 grams, 30 if you can deal with a major insulin spike without barfing) and you have a great way to induce a hyper amino and hyper insulin stake that is absolutelly great for recovery. If you follow this up with a real meal 1 to 1.5 hours later with some slow carbs and a nice protein mix you're pretty well set for max recovery.

    At 5-10% in a protein mix with whey isolate (50-60% whey plus hydro) and some micellar casein (or other slow protein) plus some flavor and spenda and you have a ultra fast, fast, and long acting protein that really tastes pretty darn good and delivers results.

    Real results require some sacrifice. "Ice cream" flavored candy-like foods deliver results--poor recovery, fat gain, muscle loss. If you work out hard why not get the maximal impact from all that effort?

    The Hydro 520 is definetly not for the weak of heart. I've eatin' many of disgusting things in my life, but never, NEVER have I tasted anything so gross. I couldn't decide if it tasted like cat litter or cat poop.
  • Author: upci@netscape.net
    I ordered the 520 in my custom formula at 15% replacing the CFM whey isolate. After reading all of the reviews about how awful this stuff was going to taste I really didnt know what to expect. BUT after trying it yesterday I can truly say that I love it!!! Sure the smell was a bit strong but it wasn't that bad. And the taste didn't bother me a bit. Taking this stuff with HRS is like drinking water because it was absorbed in my body instantly! I'm sold.

    It does taste a bit funky like they say.
    But here's the recipe I came up with that actually tastes great!

    1 cup soymilk
    1 scoop Hydrolyzed 520
    1 tsp glutamine powder
    half a banana
  • Author: storemike@yahoo.com
    yep...it tastes bad, but works great. For my pre and post workout shakes, I mix 2 scoops with 1 scoop of dextrose and 1/3 scoop sugar (plus a pinch of glutamine and creatine). It's helped me gain past previous size and strength levels.
  • Author: zapcoaudio@verizon.net
    This is one of the most effective protein powders I have ever used! And I have used some awesome stuff. To name a few, OTS's Pro-Syn -5 amino acid caps, Critical Mass amino tabs ( both of which were made at a top-secret government lab and only made for OTS-Direct and Leo Costa Jr.) No Joke. And also Dr. Mauro Di Pasquale's Amino V.3 which I take post workout. The taste isn't all that bad so long as you've got a pair. Just man-up and pound it while you lift. Doing so will not increase anabolism so much as it will provide a STRONG anti-catabolic effect. Then when the session is complete pop the aminos and kickback and wait for the surge of fresh muscle growth that will inevitably take place. It all starts with the Hydro 520. Believe that.
  • Author: cesarsju@optonline.net
    This is by far THE WORST tasting product but like many people have previously said, "Anything that is good for you, tastes bad." This is a model for that saying.
    I tried a few different things:
    1. Added in a scoop of Optimum Rocky Road whey (still was terrible)
    2. Added one banana and blended (still was terrible)
    3. Added about a tablespoon of Hershey (I'm not kidding) Chocolate Syrup - and after that it was actually tolerable...I still wanted to gag a couple of times but I got it down in a couple of minutes.

    I'll make another post when I find something that works.
    BTW - Protein Factory is a great group of ppl. I made a mistake with my CC# and they still mananged to get my order to me on time :) A+++
  • Author: Edward White (closeby152@aol.com)
    I drink my Hydro 520 straight with purified water. Way too big a deal is made over the bad taste. No problem for me. I was used to drinking glutamine peptides anyway, so it was not a shocker.

    No pain, no gain. If you want a milkshake then take your ASS to Dairy Queen.

    Knowing I am drinking the very best protein makes it easy to consume. I take pride in giving my hard trained muscles supreme quality.

    Bow to science or enjoy your strawberry creme low grade shit whey.

    I've been using this stuff just about ever since Alex started selling it - like back in the days when you could dial the 1-800 number and speak directly to Alex :) . I am 59+ years, a rock climber and have to say this stuff helps build the lean, sinewy muscle needed for that sport. I mix it with a little soy milk and flax oil - killer good cocktail! Thank you Alex for this awesome product!

    The taste? Fogeddaboutit!

    I take a powder with 520, glutamine peptides, and super bovine (among other things), mix it with water and drink it straight. Just plug your nose & you can't taste anything. Wash it down with V8 to get rid of the aftertaste & it's like it didn't happen! I think veggie juices go better with the gross proteins (especially the bovine) than sweet drinks/foods do.
  • Author: David Nemeth (gordyrocks@sbcglobal.net)
    Alex,
    I can't believe all the sissies complaining about the taste of the 520. (You should carry some crap protein bars for them) I drank it all the time with water and a big scoop of glutamine peptides. I loved it. I don't think I will be buying it very often anymore as I really don't like the molecular weight break down. Can't quite figure out how you come up with it being 520 daltons. Anyhow, I was use to a Lactalbumin Hydrolysate with a molecular weight of 220 or less. It was called Aminofit by Atletika but their out of business now, too many sissies trying to weight lift these days. I do hope someday you'd consider carrying a product as described above for us hard core lifters who don't care about taste as much as we care about results. I'm off to build a supplement out of high quality aminos. Overall, you do have some of the best protein choices one can find. Keep up the great work.

    No Guts No Glory. No Pain No Gain.

    I have not had much experience in a full variety of protein powders in my life time; seeing as how I am only twenty. But I do know one thing, the nastiest stuff ever is usually the best. In this case, this is true. The 520 is by far the worst tasting protein powder ever. I mix one cup of vitamin D milk with 1/3 cup powder close my nostrils and think, No Pain No Gain and down it, and chew gum RIGHT afterwords. If you're looking for muscle mass and serious gain, this is the product. If you're looking for great taste, you're looking on the wrong page. This website contains supplements for ONLY the serious athlete.
  • Author: Joseph Palestrini (josephpalestrini@msn.com)
    Serious product. Not a commercial protein to be mixed in a smoothie or w/ plain water. I mix it with low cal orange gatorade & vanilla WPI & WPC. Tolerable, but definitely doesn't taste good. Protein Factory is a great site and their customer service is very good.
  • Author: Howard Miller (crayne@bellsouth.net)
    As many have already said, if you are serious hard core, this is your product. Post workout and during workouts (in 1:4 blend with carbos)

    If not, do yourself a favor. Choose another protein.
