here in germany it is extremely popular for the IFBB pros here to use HA injections or HA+cortisone.Excellent suggestion. If it can be afforded, stem cells as well. There were so many top athletes in Columbia getting their knee’s injected while I was there.
I’ve heard the results are pretty wild. I would do hypoxic stem cells for the knee’s as that’s what the research has been done on with them.
CPI or BioXellerator do these.
The clinic in Texas that does Wharton’s Jelly would be another option in the US.
If you’re using nandrolone to increase collagen syntheses it may give some level of relief, but as others have said make sure you’re getting the collagen in your diet via bone broth on meals or adding it in via supplement form so that it’s there in the body.
According to the bobybuilding doc (Dr.Ritsch, people from germany who are into BB will know him ) this is especially helpful for shoulder and knee joint.
