I have been using it since my shitty rotator cuff surgery a year ago. I don't say these things often but for me the results were just short of amazing. I started with 250 mcg a day injected into the shoulder at different spots. I had pain relief the 1st day and within a month I was 98% pain free with full strength and movement.

Several months later, today, I haven't had a shot in weeks and have no pain but I've also started 4 ius day of gh so it could be helping too. It is absolutely worth trying IMHO.
