We all must learn on patients at some point, how to do Botox injections, but my answer is that if you're looking for great results, don't visit a brand new injector! Most of the time "volunteer" patients for procedures like this are existing patients at a practice whom the practice knows well and believes will 1. benefit from the procedure, 2. give valuable feedback, and 3. return to the practice for future treatments. So, you can't just "volunteer" as the patients are chosen by the injectors themselves, not by Allergan trainers.
