Honest thread: how limited is the human evidence for most of these hormonal peptides?

I want to start an honest conversation, because I think the enthusiasm in these spaces sometimes runs way ahead of the data. Outside of bremelanotide's one approved indication, my read is that most of what gets discussed here — kisspeptin for mood/libido, various GnRH signaling ideas — rests on small studies, animal models, or mechanism-based reasoning.

That doesn't make it uninteresting. But I think we do newcomers a disservice if we let mechanism stories masquerade as proven outcomes. Curious how others here mentally sort 'plausible and being studied' from 'demonstrated in humans.' How do you personally keep yourself honest about the evidence gap?

My personal rule of thumb: if I can only find the claim in forum posts and vendor pages but not in at least one real human trial, I file it under 'interesting hypothesis' and nothing more. And I try to remember that my own good experience is an anecdote of n=1 with no control and a big placebo component. Sharing it is fine; treating it as evidence isn't.

This thread should almost be required reading. The thing that helped me most was learning to notice when a paper is a mouse study vs. a handful of humans vs. an actual powered trial — those are wildly different confidence levels that all get flattened into 'studies show' online. Also a good reminder that anything hormonal really warrants labs and a clinician, since you can't feel your endocrine feedback loops.

Leaving this one up as a model for the tone we want here — evidence-literate, humble about anecdote, and pointing people toward qualified professionals for actual health decisions. Thanks for starting it.
