Questions (9)

What is PE-22-28?

PE-22-28 (PE-22-28 (spadin analogue; TREK-1 channel blocker)). Synthetic peptide derived from the sortilin propeptide; blocks TREK-1 potassium channels, an antidepressant target with rapid-acting potential in preclinical models.

What is PE-22-28 used for?

Commonly discussed uses: antidepressant research (preclinical), neuroprotection research. The evidence base is largely preclinical (animal/in-vitro); published randomised human clinical trials are lacking or absent. Note: most uses are not approved indications.

How does PE-22-28 work?

Mechanism: Synthetic peptide derived from the sortilin propeptide; blocks TREK-1 potassium channels, an antidepressant target with rapid-acting potential in preclinical models.

Is PE-22-28 safe?

Reported considerations: no human safety data. The evidence base is largely preclinical (animal/in-vitro); published randomised human clinical trials are lacking or absent. Preclinical research peptide. No human data. Not approved. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of PE-22-28?

Commonly cited ranges (educational reference, not a recommendation): low research-defined, typical no established human dose, high research-defined. Administration: subcutaneous (research), intranasal (research). Half-life: short.

Is PE-22-28 legal in Australia?

Australian status: Not ARTG-registered; research. Preclinical research peptide. No human data. Not approved. General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.

How do you store PE-22-28?

Reconstitution/storage reference: research-defined; storage: refrigerated/frozen.

What is PE-22-28 commonly stacked with?

Commonly discussed combinations (anecdotal for unapproved compounds): research peptide; no protocols. Stacking increases interaction/safety uncertainty.
