DHC is stronger but it is also a more stimulating and less nod like buzz. I also would like to add that the oral bioavailibility of the drug is ridiculously low, and if you're looking for a recreational buzz with a lower dose i'd suggest plugging it.
Also, the constipation from DHC is unmatched in terms of any other opiate i've ever tried. Honestly, that stuff bungs me up like there's no tomorrow and when it finally does come out it's like i'm giving birth.
