I am a 39 year old woman with SPMS. I have almost zero mobility and am bound to an electric wheelchair. I have personal assistance in all my daily activities.
I received a mix of DF4/DF6 to begin with to determine which would be better for me. I felt a massive difference in my legs after half a dose of DF6 (for two days) and ordered a full dose of this afterwards. However, I did not have the same experience after the second dose. My arms have improved and are more mobile, while my legs are back to status quo.
I will definitely be ordering another dose after a while.
