I have been carrying a small bottle of the powder with me with a little scoop but I can only mix it in my office where i have easy access to everything. The problem with doing it when u can is that your doing it inconsistently. I have no idea if that matters but I would think it does. (Not my first choice.)

Alternatively, we can carry with us 4-5 little plastic bottles that hold no more than 150ml. You fill each little bottle with your powder and take that with you. Then when u need a dose, just fill each bottle with 100ml of water (the recommended amount). Then close the lid and shake. Voila! The 5 bottles will be small. (2nd choice)

Alternatively, bring a small container with 5 small divisions or 5 small individual containers. You'll also need a mixing bottle with a large neck so u can get the powder in there and of course aqua. (3rd Choice)

Frankly, it all sounds pretty messy.

I think Rick's (reverett123) suggestion is the #1 choice with Zandopa powder unless they start putting it in pill form.
