I like Kre-anabolyn. It just leverages ecdy's glucosal disposal properties, which I think are way undersold vs. the protein synthesis angle. The formula includes kre-alkalyn, RCE, 4-hydroxyisoleucine and L-dopa. Pretty intense stuff.
I've also used Thermos Ecdypure, which I enjoyed. I've used various other brands with success but always came back to Kre-Anabolyn.
