Long post, sorry. Sermorelin: what actually has human evidence behind it, and what is extrapolation from animals?

I would rather have a narrow conclusion and be right than a broad one and be interesting.

Most of the popular protocols are borrowed from clinical populations and applied to healthy people without comment.

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

Water retention and mild lethargy in the first fortnight are the usual pattern.

How do you separate the compound effect from the routine around it?
