Good question. And my response will be impartial because I am not a rep.
I'll give the edge to a "highly-dosed" Ursolic Acid transdermal. Slightly better recomp and thermogenesis effect.
Also, Ultra-11 might require a light PCT. Ursolic Acid doesn't. My only quip with Ursolic Acid is that it seems to effect sperm motility negatively. But should not, once off.
