"Research use only" is a vendor label, not a legal category that permits human use. It does not exempt a product from medicines law.
- 03
Importing, supplying or promoting it for human use can fall under medicines legislation in Australia. This page is general information, not legal advice.
What Dihexa is
An experimental angiotensin-derived peptide reported to be an extremely potent promoter of new synapse formation in animal models of cognition.
Dihexa is a small peptide derived from angiotensin IV, developed to cross into the brain and promote the formation of new synaptic connections. In rodent models of Alzheimer-like impairment it improved cognition at very low doses by potentiating hepatocyte growth factor signaling.
Mechanism: Potentiates hepatocyte growth factor and its c-Met receptor to drive synaptogenesis, the formation of new synaptic connections.
Regulatory history: Not FDA-approved; experimental
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for Dihexa at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
