[EX Q]: Well this stuff was crumbly and would not stick to itself. It was like wat sand. I couldn’t knead it or work with it at all. Added water and pushed it in the mold and it cracked in thousands of pieces. Worthless stuff don’t buy it.
[EX A]: negative

[EX Q]: Why didnt I read the reviews! Typically like vital proteins but this stuff is awful. Taste terrible and smells like vomit. I'm trying to drink it anyway because it was expensive but yuck.
[EX A]: negative

[EX Q]: The product itself was fine, but the yellow envelope that contained the product had been torn, then taped back together. The package was then left at the end of our driveway on the ground. Thankfully my husband saw it before it was stolen. Please find another carrier.
[EX A]:
negative
