Same comment as Thomas C.
Even after shaking vigorously, no matter how long or quickly it takes you to drink, there is alot of residue left in the shaker, glass, etc. It’s the most I’ve ever seen leftover after decades of preworkout products. I’ve been using this product for the better part of a year.
I actually began searching for the answer, so I can at least find out which of the ingredients is being left behind, and I wasn’t consuming until recently deciding to just put the powder directly from the scoop into my mouth. (Btw, do not inhale or exhale when you do that, especially, if you’re like me, and are asthmatic. Bad scene).
Otherwise, I consider this and other Ballistic products to be good products.
