Well folx I got my patches in and I'm on day 3. I can now officially say walking around Japan while I visit for 10 days and for 7 hours of hills etc I am not sure what the deal is but the first day I didn't put the patch on I was sore the next day. Soon as I put the patch on I felt as if I have consumed a huge protein shake and feel like I can walk all over Japan . I feel very great full for this patch.
