I had experience with 7OH-DHEA and Albuterol.

The first during PCT and I'm sure it helped to keep most of the gains. I also used 7OH at a lower dose when on a bulker. It somewhat limited the fat gains, but this wasnt due to its cortisol-suppressing property rather the anti-lipolitic action of 7oxo-dhea to which it converts to in your liver.
I took Albuterol on a cut/recomp, not during PCT so I cant say much. I have never tried Clen and I cant compare it directly, but at high dose it worked for my goals.
