It's not very common for practitioners to offer Botox by volume. Most offer by site (frown, forehead, crow's feet lines) or unit. Botox comes packaged in a vial contaning 100 units of dry powder. This is then mixed by the provider with sterile saline resulting in a concentration measured as units/0.1cc. Most make the ultimate concentration to be 4 units/0.1cc and most will treat the frown lines, for example with around 24 units (0.6cc).
Hope that helps.
