Everyone is different and some orals are more toxic, but 4-6 weeks is considered cycle lengths likely to do minimum damage.
Injectables are less hepatotoxic and can be run longer (16 weeks or longer) so most people would prefer longer cycles since many of the effects of AASs may only be observed beyond 6 weeks or longer (depending on other factors such as diet, training, genetics).
Steroids carry risks no matter how you look at it. The decision of oral versus injectable is a personal choice for many. Yes, an injection into a vein can be serious but when handled by a well educated user, trained on proper cycles and techniques, the risk is probably less than hepatotoxicity associated with orals. Once you irreversibly screw up your liver, you're done son.
