yep guys im in the same boat... i already have like 3 bottles of each....
my things is which one will i run first....
here's what i came up with in my search....
Sides: either way the only thing that really stuck out was that they're both methylated so use ur liver protectants and add some b pressure supps.....
Results: I seem to see that ergo has the advantage in the strength category, but sd has the advantage in the less water weight gains, more of a rock hard lean gain look to it....
Conculstion: I just read that Phera-plex will be out next week and i heard that it will be basically the same as ergo but maybe better, so just go with the sd if ur gonna buy one because you may be able to get more than one cycle outta the sd bottle and also, you can stack the phera-plex with sd but not with ergo....
hope that helped a little.
