If you buy whey concentrate from Protein Factory or True Nutrition there is about 2 g of carbs per 20 g of protein and they are $6/lb.  Are you willing to pay triple the price to save a couple grams of carbs?  If you are sticking to meat and ULC vegetables for your other meals, you won't even come close to 30 g of carbs.

That's a bit of hyperbole. TN's Cold Filtration Isolate is 2.4 cents per gram of protein. TN's High Grade Whey Concentrate is 1.9 cents per gram of protein. That's only 26% more in cost, which decreases even further once you factor in flavoring and shipping. It is marginal at best.

I was referring to the post above where someone mentioned protein that was $42 for 2 lbs.  I still don't understand the obsession over isolate if you are not lactose intolerant.  25% is still a pretty big increase in cost.  Buy concentrate and use the money you save for better food and additional supplements, the couple grams of carbs won't add up, but the dollars will.

Another way to look at it is that TN's whey isolate is still substantially cheaper than most name brand concentrates. It also lacks the emulsifying products that many of the concentrates use, including TN's own cheaper WPC products. At the end of the day, we're talking a few cents extra per serving for a better mixing, lower carb, higher versatility and more protein dense product. For most people, especially the 1 in 10 American adults who suffer from some form of lactose intolerance, that's an expenditure that is worth it.

It does not mix better nor is it more versatile.  Look if you or anyone else are willing to pay extra that is fine (I buy a small bag of isolate for my AM accelerators), I have no problem with that.  My problem is that there is a culture on these forums that you must buy whey isolate and it simply isn't true.  There are people on this website that are short on funds and have trouble affording all the supplements and hugh quality food.  My aim is to show them that they can save money in certain areas, one being buying a good whey concentrate (I agree I wouldn't buy any of the commercial junk) from TN or PF.

Isolate is quite a bit more versatile specifically because of the singular macro content, particularly for cooking applications as well as for flavoring purposes. I don't know what isolate you've used but having tried all 5 of TN's the isolates mix better than the concentrates.I wasn't suggesting that one couldn't use concentrate but the CBL plan specifically calls for isolate. The price differential between isolate and concentrate is much smaller than the price differentials between many of the other products used in the CBL supplement plan.I'm all for reducing expenditures when possible. In this instance, for at least a certain set of people, the small cost savings associated with concentrate aren't worth the additional costs, particularly for those with lactose intolerance. There is no judgement on my part (or indeed in any posts I've seen on this topic) for people who choose to use concentrates for financial reasons.I think you're taking this far too personally. My goal in almost every thread has been to save people money on their supplement costs. I just want to ensure that people are getting a complete set of information before they make their purchases.

Well I have used both concentrates and isolates from PF and TN (I buy CFM when I buy isolate) and I notice no difference in mixability, however I don't even think that it is important anyway.  I still don't understand your versatility argument.  I don't think I am misleading anybody.  My little crusade here is in response to your post which seems like you were trying to persuade him not to buy concentrate after I told him it was ok to.  If that was not your intention, I apologize.

I do a lot of cooking with protein powders and isolates have tended to work better but I understand that's an edge case.My only point was some people prefer to get as close to 0g on ULC as possible and that concentrates do contain a marginal amount of carbs. I certainly agree that they're not likely to impact progress in any demonstrable way.I agree, I don't think you're misleading anyone. I'm absolutely glad people are looking out for the bottom line and I think there is definitely a valid place for concentrates. I too apologize if you or anyone else felt I was suggesting they weren't useful.
