I'm running 1250mg/wk right now in conjuction with a pheremone trial for DS and it works very well. Stacks with this particular pheromone well too infact! 19-nordiol is actually a Searle 1958 patent anabolic, but they marketed the diprop version. No conversion is required, but dose is the key. It still takes as much or less as it does for 4-AD cyp, so one shouldn't be surprised. I'm using the 1fast powder @ 250mg/ml. 5%BA, 12.5%BB, and zero pain even with 4ml glute depos.
