I've been researching it pretty hard and every log I've seen said it's great. Now I don't know about repairing a torn tendon but if it just a little frayed then yes but completely torn not connected no. I've read about guys who have healed torn muscles in a short period of time. What I've read is that you load at 5mg a wk for 4 wks then you do a lower dose to maintain. Most started seeing result on week 2-3.Everyone had positive results.

I used it a while ago, but I was away when it came and it didn't get refrigerated. I was also still trying to workout pretty hard while taking it, so the results were not as good as I had hoped for. It did help but I would constantly aggravate it so.....I feel you need to rest when you try it to heal a tendon. If you continue to create trauma it will not be able to heal properly.
