Protein percentages
 
In an attempt to save a little cash, I was thinking of building my own protein powder. I intend to use Whey Isolate, Milk Isolate, and Micellar Casein.

I was wondering what would be the best percentages of each? I've read here that that the Milk or Micellar should be higher than the Whey though.

Thanks in advance...

I'm not sure that there is a "best" formulation but the following should suit your needs -

Total Cost: $11.67 http://www.trueproteincanada.com/images/spacer.gif
Pounds of mixture: 1Custom Mix Ingredients:i

[SHOWTOGROUPS="6"]
Milk Protein Isolate - 30%
Micellar Casein - 30%
Whey Protein Isolate Cold-Filtration -40%
[/SHOWTOGROUPS]
(the price includes aminogen and BSL flavouring and is in Canadian currency - trueprotein.ca. In US funds it's $10.53/lb. Shipping is extra)

Metabolic drive from Biotest works out to $13/lb - shipping included (US $)

Evopro by Cytosport, bought from 1fast400 works out to $12 + shipping (US $)

Propeptide works out to $13/lb from 1fast400.com

Actually, I was wondering what would mimic Metabolic Drive's percentages? Would the above post represent that somewhat?

Carter Schoffer March 27th, 2007 12:13 PM

This is the ingredient list of Metabolic Drive -

METABOLIC DRIVE® ADVANCED™ PROTEIN, LOW-CARB MRP — CHOCOLATE: protein blend (whey-protein isolate (milk), micellar casein (milk), milk-protein concentrate), cocoa powder, natural and artificial flavors, sunflower oil, polydextrose, glucono-delta-lactone, cellulose gum, potassium chloride, lecithin, mono and diglycerides, sucralose, silica.

Ingredient lists have to detail the contents of the product on a descending basis from highest percentage constituent of the given product to the lowest percentage constituent. Knowing this, from the above you can see that whey protein isolate is the most abundant fraction of the forumula with silica making up the smallest fraction.

Sticking to the proteins, we know that whey isolate is the most abundant, micellar casein is the second most abundant and milk protein concentrate rounds out the three in last place, so to speak.

Now because it's a proprietary blend, only Biotest knows the actual %s of each.

It could be

Whey isolate - 50%
Micellar casein - 30%
Milk protein concentrate - 20%

It could also be

Whey isolate - 97%
Micellar casein - 2%
Milk protein concentrate - 1%

Or it could be more evenly (and in my opinion more appropriately) weighted as close to

Whey isolate - 40%
Micellar casein - 30%
Milk protein concentrate - 30%

Now you'll notice that Biotest has gone with milk protein concentrate instead of isolate. There could be a number of reasons for this. Two of which could be

(1) They're cutting cost.

(2) They want the longer absorbency curve with the concentrate (concentrates take longer to absorb than do isolates)

In the end, the only truly appreciable difference, outside of theory, is GI tolerance. Concentrates are usually less friendly to your GI track than isolates are.

Carter,
Thank you so much for the detailed response! The 40/30/30 is the way I'll go

Surge breakdown percentages
 
Just woundering, if you might have a mimic breakdown list percentages close to the surge recovery drink.

JJC April 7th, 2007 01:35 PM

As far as I know, whey hydrolysate is the only form of protein in Surge, as it absorbs extremely quickly, and that's what you need in a recovery drink.

Grim Skunk April 19th, 2007 11:27 PM

Nobody has the ratio for each ingredients to build a mix similar to surge?

Is the fast recovery formula from true protein OK?

T Ham April 20th, 2007 03:04 AM

My best approximation for Surge is something like:
55% Maltodextrin
5% Dextrose
30% High Grade Hyrolyzed Whey Isolate
5% BCAAs
5% Gluatamine

There is also Phenylalanine in Surge if you want to throw some in.

Someone else probably has a better formula though.
You can't really beat Surge's taste though. When I say you can't beat it, I mean not just that it tastes awesome, I also mean that anything that isn't made specifically for hydrolyzed whey will taste like crap, unless you want to throw some Cranberry Crystal Light in every shake (nothing else works.)

I haven't tried any other company's PWO formulas, but most should taste at least alright if they have hydrolyzed whey in them (they probably wouldn't sell it if they couldn't make it taste alright.)

T Ham June 27th, 2007 03:08 AM

Oh, I remember over at T-Nation, they have said that Low-Carb Metabolic Drive is very close to 50% micellar casein.
