It's wild to me in the sense that I wouldn't do it, but not wild in the sense that it's surprising.

This isn't anything new. Certainly it's easier nowadays to get stuff from overseas than it was 15+ years ago. But those black market steroids you mention probably weren't much (or any?) safer, honestly, regardless of track record.

People have been experimenting with drugs for longer than I've been alive, and will continue doing so long after I've turned to dust. San Francisco, in particular, has a long and storied history with the sort of experimentation described in this article. The author seems to have made the mistake of thinking that this sort of thing is incredibly common and "everyone is doing it" here, but I have no doubt that it does exist and people do it.
