Does anyone know the Innotox to Botox ratio?

I will be injecting Innotox into my masseters and lips today but I want to make sure I have the ratio right. I have seen some people say the ratio is 2:1 Innotox to Botox and I have seen some say the ratio is 1:1. Does anyone officially know which is correct or anyone with experience using Innotox share which they typically follow?
