Some are isolate, some are concentrate or a blend of the both. (most are blends) Some have added sugars etc. Just read the ingredients on both labels and base your decision on that.

I usually get ON protein for 40ish for 5 lbs. I have a website plus a coupon to get twinlab protein for 20ish for 5 lbs. But if its not as effective and doesn't produce the same results then the $20 savings may not be worth it.

Whey protein typically comes in three major forms: concentrate, isolate, and hydrolysate.
Concentrates contain a low level of fat and cholesterol but, in general, have higher levels of bioactive compounds, and carbohydrates in the form of lactose — they are 29%–89% protein by weight.
Isolates are processed to remove the fat, and lactose, but are usually lower in bioactivated compounds as well — they are 90%+ protein by weight. Both of these types are mild to slightly milky in taste.
Hydrolysates are predigested, partially hydrolyzed whey proteins that, as a consequence, are more easily absorbed, but their cost is generally higher.[8] Highly-hydrolysed whey may be less allergenic than other forms of whey.[10] They are very bitter in taste.
If you can save $15 on whey that has 85% whey then 90% then go for it. You can use that money on good quality food. You will not see a different between the two.
no concentrate for me due to lactose..

Isolates are the whey to go! I've been using Synthetek's SynthePURE WPI and have to say nothing compares!

Good basic post. I switched my pwo protein to hydrolysates by BNRG called Proto Whey. I loved it and used it for well over a year after speaking with Monica Brandt, Scott and the creator of this product at the Arnold in 2010.
However, earlier this year I began to have various GI issues and started to think it was dairy. I would have issues after my fav cheesecake, even a glass of milk with occasional cheat day pancakes. But when I cut out all dairy it continued until someone suggested ALRI Humapro.
I said I see the Humapro ad and it seems interesting. But it has no calories and I'll miss my chocolate, peanut butter & banana pwo shake!
I have been using Humapro for 4 months now and will never go back to whey. I am leaner, fuller, harder with no initial changed in diet and training and no more "bloated belly"!
Go with Isolates or if you want go even better, go with something Pepto-Pro. I have to use higher quality protein because lower qualities destroy my stomach.

"PeptoPro is a casein hydrolysate produced from milk protein. Casein is enzymatically hydrolyzed peptides using a new and patented debitterizing process. This makes it the first hydrolyzed protein that can easily be used in a protein shake."
Stop sucking on a cows udder! Cannot beat ALRI Humapro. NOPE!
I too was a skeptic. Didn't wanna give up my Choco/PB/'nana MILKshake.
My GI system said thank you Black! BA's fuller, leaner, and now more muscular 5 weeks into keto down 13 fat pounds, lean mass up 3-4 pounds!
No all whey is not the same. The level of processing, the fillers and overall product quality vary from company to company. there are some good ones out there for money, dymatize iso 100 is a great product and taste is good. If you don't mind the shipping cost TrueProtein's quality is unmatched.
