Why Won't Doctors Inject a Smaller Amount of Dysport?

Not everyone requires the exact same amount of Dysport for treatment so you just need to find a doctor that will use the amount that works best for you.  It is not at all unreasonable to use whatever amount gives you results.  

I recommend that you go see another doctor who will work with you.  If a small amount works for you, there is no reason not to use it.

Dysport can be customized, but it also depends on the state medical board restrictions. Botox and Dysport are labeled as single use vials, so in Nevada (and perhaps Arizona), restrictions are set in how doctors can use the vials. This is why we don't customize a per-unit price structure in my office for Botox or Dysport. I am thinking the physicians' offices you contacted in Arizona may be following the same protocol. You can use less if you want, but you may end up paying for more....

In my practice I offer Botox, Dysport, and Xeomin and there are no "minimum amounts". I will only inject what each patient either needs or wants, and I charge by the number of units injected, not by the area. I think that is the most fair way so you are getting exactly what you pay for. I recommend you keep looking for another doctor.
