Cool thanks for the explanation, so the WPI you guys sell is a purer form of a better quality than the ON one I am currently using??? is that correct??
Like I said earlier, I will need to buy some more protein, when the time comes and am open to suggestions.
Already started using BN Pre Workout and BCAA's and am happy with my purchase and the price, as well as the fast service.
The ON product you have is not an Isolate.
It is what is commonly called a protein "blend".
A blend is basically a combination of WPC/WPI and often many other proteins. Companies make these for various reasons, but the simplest reason is that they are much cheaper to manufacture than WPI's (as WPC is a much cheaper protein)
Now, the problem with blends is that it is very hard to know how much WPI and WPC is in a blend (as most manufacturers won't tell you), but as a very simple rule the closer the final protein ratio to 80% the more WPC, the closer to 90% the more WPI.
I don't know the exact numbers but the ON appears much more like a WPC than a WPI Nutritionally.
Another great way to tell how pure a WPI is is based on fats and carbohydrates, as the ON product has close to 10% carbs this is another indicator that uses a lot more WPC than WPI.
Our Isolate is 100% pure WPI, in that the only protein used in it is WPI. If you look at the Nutritional Value for this it is miles ahead of any blend in terms of high protein, low fats and carbs.
If you want a product which is similar in terms of nutritional quality to the ON product then the WPC of ours is much closer. It actually has similar protein to the ON product with less carbs.
Basically if you want to compare similar proteins our $99 product for 5kg is on a similar level to it.
Saying all of this, the ON product is still a popular one, people like the taste it mixes well and it has been around for a long time. It is a good all round protein, however due to the typical supply chain (it is made for the retail market) it can't get close to ours on a price vs price basis.
