PE 22-28 showing rapid antidepressant effects in animal models, what y'all think?

Saw something about PE 22-28 the other day and it kinda stopped my scroll. It's this synthetic peptide that comes from spadin and blocks TREK-1 potassium channels. The wild part is how fast it seems to work in animal models, way faster than SSRIs, supposedly because it ramps up neurogenesis and serotonergic signaling almost right away.

For what it is worth, anything that promises "rapid antidepressant effects" gets my eyebrows up. SSRIs are great for some people and a slow miserable slog for others, so I get why folks are paying attention. But it is still preclinical, no human safety data, no real dose range worked out. So please do not treat this like the next great thing to run out and try...

The biohacker in me is curious though. A short half-life peptide acting on ion channels instead of serotonin reuptake is a different angle than most things floating around. Curious if anyone with more neuro background has thoughts on TREK-1 as a target, or if this looks like another flash in the pan once you dig into the literature.
