I've been using Arrowhead plastic water bottles. Fill one up with JACK3D to drink on my way form work to the gym, and then another with my PWO BCAAs. My car ends up filled with fucking plastic bottles. Seems sort of silly to use a new one every time and work is about to phase out plastic bottles. Plus its a huge pain in the ass to pour powder into bottles like that (I use a piece of paper as funnel, fucking thing sucks). What do you guys use? I want something that won't leak and is easy to wash and dump powders into.
