Well damn, it looks like I went and caught the research bug.
I've been looking into myostatin and the first thing that comes up are articles and forum posts related to bodybuilding. Specifically all of this is related to inhibiting and/or blocking myostatin in order to promote muscle growth. There's also an abundance of supplements out there that claim to inhibit myostatin (though most of them appear to be either outright bogus or, at most, have a very minor effect).
Myostatin inhibition also appears to be something being explored to combat muscle atrophy from conditions like muscular dystrophy and cachexia (the severe weight and muscle loss suffered by people with AIDS, cancer, etc.)
So there seems to be a lot of research going on to inhibit myostatin (follistatin is one of the inhibitors being explored, by the way) but I can't seem to find any research revolving around promoting it. But I'm definitely starting to feel like finding a way to promote myostatin is going to be key in beating whatever Dr. Ink is up to.

The role of myostatin in muscle wasting.
