Apparently, most people seem to suggest that Sust needs to be shot EOD for "even blood levels" because "it has prop in it." However, the research I've seen seems to suggest that both sust and prop need to be shot EVERY SINGLE DAY to maintain "even blood levels" and an every other day protocol will still produce varying "blood levels." So why do people frown on an e3d protocol when an eod will still produce varying levels?
