Yes, it does. Typically this is a reasonable assumption. (There is 
obviously a lot of stiring involved.)

I note that while it may be very difficult to measure out tiny volumes 
of a liquid or solid, it is probably quite *easy* to take some diluted 
botox and confirm exactly how dilute it is or isn't. (This is precisely 
the kind of job my company gets paid for.)
