Community-reported ranges are anecdotal and not clinically validated. Evidence grade shown reflects the strength of available human data. Not a prescription. Legal status varies by country and changes over time; verify locally.

Overview

A small angiotensin IV–derived peptide developed in preclinical Alzheimer's research for its potent synapse-forming effects. There is no human trial evidence, and its mechanism raises unanswered safety questions.

Mechanism

Proposed to enhance hepatocyte growth factor (HGF)/c-Met signalling, promoting synaptogenesis in animal models.

Evidence

Animal / preclinicalWhat does this mean?

Very thin: striking rodent synaptogenesis data but no human studies; potent growth-factor signalling warrants caution rather than enthusiasm.

Community-reported information

Community reports vary. Anecdotal, unvalidated and poorly characterised; general information only.
