Looking at PE 22-28 as a fast‑acting antidepressant peptide – thoughts?

I came across the PE 22-28 entry on the site and it got me thinking about how fast‑acting antidepressants are talked about these days. The description says it’s a spadin‑derived peptide that blocks the TREK‑1 potassium channel, which in animal models boosts serotonergic signaling and neurogenesis faster than typical SSRIs. Anecdotally, I’ve noticed that when I experiment with compounds that affect glutamate or GABA pathways, mood shifts can feel pretty immediate, but the safety picture is always vague for peptides that haven’t left the lab.

Since human data is basically nonexistent, I’m cautious about jumping in without solid bloodwork or a clinician’s input. Still, the mechanism lines up with what some researchers are chasing for rapid‑acting mood aids, and it’d be interesting to see if any small human trials pop up. Has anyone here tracked mood or cognitive changes with something that targets TREK‑1, even indirectly? What markers would you look at first if you tried it?
