Considering dbol and similar have been used for decades? The sides are very well known. SARMS on the other hand haven't been in widespread use for nearly as long as something like dbol.
Unless you have a pre-existing liver condition or something like that, small doses of dianabol will not kill you. Also, the idea that the risk of using steroids like dbol are considerably worse than the risks of using SARMS is not totally accurate.
In general, any legal alternatives to well known steroids will either be worthless or more hazardous to your health than steroids that have been used for decades and are quite well understood.
