I think there are far worse, but d-bol is the most commonly "passed-around" gear I've seen. Thousands of tabs for what much less of something else would cost... lots out there, not a lot who know what's what.
Might be that there are more cases of abuse because of this, but I'm not really to sure about that either.
Maybe it's a nasty rumour started by d-bol users' backs to discourage them from using it... damn pumps!
Although there is one more that is worse but it's not available and it's only for research purposes. It's a c-17 alpha alkylated trenbolone. Only used in mcg too that's how toxic it's supposed to be.
