Ok... I know I am a little late on this one, but I kind of have to respond... being called out by Blue and all. 
I use Nitrotech Hardcore. While there are cheaper mixes out there, Ireally like the taste of it. I have had vanilla, strawberry, chocolate, and (more recently) double chocolate.
When I was trying to bulk up, I was taking a double-shot in the morning and then a single later in the evening. This was in addition to eating large healthy meals and the occasional protein bar. I was overseas during these times and I used water, as milk was hard to come by. I was also expending a lot more calories each day than I might do here in the states.
Now days, being happy with my weight, I normally have 1 shake a day. It's a double-shot, with peanut butter, ice and skim milk. I throw them all in the blender and it taste a lot like a reeses peanut shake. 
My weight is pretty stable with a decent diet and workout routine... YES, Blue, CROSS-FIT ALL THE WAY!!!! :D
... and I am nowhere near the size of Remy. Nor, can I call myself a powerlifter of any sort. However, I was a long-time skinny guy (around 175 lbs) who is now 205+, benching 350, deadlifting 450, still running a sub 10min 1.5 mile, all while having the same waste-line as high school (when 150lbs)... and that was a couple years short of 20 years ago! LOL
