Thoughts on the latest PE 22-28 research for mood and neuroplasticity

I came across the updated peptide page for PE 22-28 over at ResearchSafe and it got me thinking again about those fast‑acting antidepressant claims. The description says it’s a spadin‑derived peptide that blocks the TREK‑1 potassium channel and has shown rapid antidepressant‑like effects in animal models, plus it’s being looked at for neurogenesis and synaptogenesis. I’ve never tried it myself because it’s still preclinical and there’s no established human dose, but the mechanism makes sense to me from what I know about serotonin signaling and potassium channels.

Honestly I’m curious if anyone here has seen any human case reports or small trials that haven’t made it into the big databases yet. It feels promising but also a bit early to get excited about, especially given the unknown safety profile. What do you all think, worth keeping an eye on or just another preclinical curiosity for now? Let’s discuss.
