My friend who lives in Florida had been trying for months to get me to try RTPR, but I was skeptical. Finally, just to satisfy him, I ordered the sample pack. A couple of days later I woke with my lower back hurting much worse than it had in a long time...Well,I thought I would try some of the gel on my lower back. I did and was amazed about ten minutes later when I realized I had [relief]. The pain was [relieved] all day and night! The next morning I tried it on my knee that was hurting me so badly I could not sleep and I got [quick] relief! Thank you!
