I am not a cactus person, but will wager its a Cereus peruvianus

Pilosocereus pachycladus. Cereus has larger longer spines. They are related, but still different. Pilsocereus has also yellow spines for the most part.

Sounds good, thanks for the input!

Noah, soon you'll be ready to cut that etiollated piece off and start a new plant with it (also, the original plant will grow out of it). That's, of course, only if you want to rid the plant of that curve. Normal growth will resume with enough sun. It's a nice plant. Pilosocereus have some of the bluest colours available, along with lateral wool and cephaliums and flowers smelling of freshly-shucked corn.
