Water. Lots of it.
I don't use Creatine. Not too fond of its anti-diuretic effects, and I'm too cheap to invest in higher quality creatine that comes w/o them. Besides, my diet contains enough meat/fish as is.
No omega-3 supplement, also for the reason stated above.
No fiber supplement either, as veggies of all kind, especially broccoli/cauliflower/spinach, are my favorite food. The joy of eating at a buffet-styled college cafeteria everyday.

EAS Protein/Muscle Milk: yes, but moreso because I like how they taste/mix with different things/bakable. Weird, I know.
