Hi Korgman12 - Yes, I'm still using the Protocol 525. I'm looking forward to later this year when hopefully they will start shipping a liquid version which may be a little easier to take and manage. I have been seeing more improvement with the numbness in my feet which gives me even more hope at my older age. I've also been making sure I keep my feet and legs moisturized daily which I didn't always do in the beginning of my journey.
