I have used it and it works great. However I'm not one of the people who it cured permanently.
I does @ around 2mg/lb. The closer to the joint the better(with out injecting articular). If you use too much it will give you diarhea & a mean ass headache.
I used it EOD for 3 weeks. After about a month off of it joint pain started slowly coming back.
Still yet it is something that isn't just masking the pain. It is healing the tissue. In Germany the human version is called Arterperon(If I remeber correctly) by Lutipoid(may have that co name all fucked up too). Anyhow it's the same exact thing as the vet sold here. Same everything exept it's labeled Adequan for vet use only in the U.S.
I am going to use it again. Which will be the 3rd time this year.
BTW I use an insulin needle to inject. Taking fish oils (fuck the caps get the liquid bottles- they're way cheaper) all with vit C msm gcs and GH etc. -anything to assist the body in repairing would really help by working synergystically.
