Trying to separate three different claims about melanotan II: that it is the right molecule, that it is the right dose, and that it does something useful.

My rule now: if a claim cannot survive being written down with the numbers attached, it is marketing.

If you need three other compounds to notice the first one, you have not tested the first one.

Mechanism is not outcome, and a plausible pathway is the most expensive kind of evidence there is.

Curious whether the popular dose has any basis or is just the convenient one.
