equipoise, deca, dbol, anadrol are probably the top few.

About to run my second cycle and I was wondering what's some good stuff for joints? My knees gave me issues last cycle and have been acting up lately as well.

equipoise, deca, dbol, anadrol are probably the top few.
Npp or deca

I've always used deca, but NPP is reportedly preferred by many due the shorter half life (haven't had the opportunity to try NPP yet)... deca at 200-400mg per week has worked for me.
I use npp for joints, prolly would be better off with deca I just dont like how long it lingers in your system.
