ADNP-derived neurotrophic peptide: in aged rats it reduced cognitive decline, increased BDNF and restored neurogenesis.
PE-22-28
Minimum order 2 vials or 2 pens — delivery in 2 weeks
Spadin analog and TREK-1 channel inhibitor: it inhibited TREK-1 with an IC50 of 0.12 nM (vs 40–60 nM for spadin) and reduced immobility in the forced swim test.
Illustrations of the product — not photos of a specific batch.
IC50 0.12 nM — PE-22-28 inhibited the TREK-1 channel far more potently than its parent spadin, with an IC50 of 40–60 nM 1.
In the forced swim test in an animal model, it reduced immobility — a marker of depressive-like behavior.
After short-term administration, neurogenesis was recorded in the same model.
What we don't know: whether this potency translates into a matching effect in humans.
Research use only, pure — nothing to do with medical treatment.
0.12 nM vs 40–60 nM. PE-22-28 is far more potent at TREK-1 than spadin 1.
Less immobility in the swim test, neurogenesis afterwards. A clean finding, not bro-science.
No promises about mood in humans — we never say that.
Everything we sell is for research, purity tested.
What we don't know: action in humans. Research use only, pure.
Imagine a key that opens a lock hundreds of times more easily than the old one!
PE-22-28 inhibited TREK-1 with an IC50 of 0.12 nM, vs 40–60 nM for spadin 1 — numbers that speak for themselves!
In an animal model, less immobility and more neurogenesis after short-term administration — yes, you read that right!
Purity, though? No compromises, ever.
What we don't know: humans, duration. Research use only — and we mean it!
