For some reason you list protein whey isolate but that is the last on the list of the ingredients that comprise the "protein matrix". It's mostly concentrate. It's pretty weak protein powder as well. 22 G of protein. Also 2 G of added sugars. Sucralose is pretty nasty sweetener. If you just talking dollar to protein ratio I guess it's a decent deal.

That is copied exactly from Amazon. It is not something the poster did intentionally to mislead, as you have inferred.

It's been a long time since I've had Syntha 6. Lots of calories per protein, but tasted good. I can't recall what it did or didn't do to my stomach. Nostalgia.

Paying this price for a product that has WPC as first ingredient is not a good deal. And this product also has lots of fillers. Not necessarily a bad thing as I do think BSN Syntha6 has its place if the price is good. But this price is not good at all for WPC as a first ingredient protein powder.

Showing $48, no coupon. Even aside from that, the macros are off (at least for me trying to lose weight) 200 calories for 20g protein without even factoring in the liquid (milk)

Does nobody on Slickdeals understand what "isolate" means?

200 calories and only 22 grams of protein.

This is trash. Each gram of protein has 4 calories. So 88 calories are protein and 112 calories are filler and carbs.

I previously used this as added flavoring back when Soylent still made powdered Soylent (before they were bought out by private equity). I'll have to see how it goes with Plenny.
