It works good. Speeds up a lot of different injuries. I took it for 5 weeks for a wonky shoulder that was hurting for over a year. It was pain free after the 5 weeks. Also have an arthritic knee with no cartilage left and it feels better than it has in years. Way more effective if you use the injectable forum. The jury is out if it makes a difference where you inject but closer to the injury seems to be what works for most. TB500 is also a good peptide for injuries. It takes a lot of the pain and inflammation out of the injury. My plan is to take a combination of the 2 prior and during my sheep hunt this year. My knee swells like a beach ball so hoping the combo of the two will keep me in better shape
