Half-life
not well characterised in humans
Administration
oral, subcutaneous, transdermal (anecdotal)
Typical dosage*
low: research-defined · typical: no established human dose (8-20mg anecdotal, unvalidated) · high: unknown safe ceiling
Researched for

Questions (9)

What is Dihexa?

Dihexa (Dihexa (N-hexanoic-Tyr-Ile-(6) aminohexanoic amide)). Angiotensin IV analogue / HGF-c-Met pathway modulator. Reported to potently promote synaptogenesis (preclinically) — orders of magnitude more potent than BDNF in some assays.

What is Dihexa used for?

Commonly discussed uses: cognitive enhancement research (preclinical), neurodegeneration 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 Dihexa work?

Mechanism: Angiotensin IV analogue / HGF-c-Met pathway modulator. Reported to potently promote synaptogenesis (preclinically) — orders of magnitude more potent than BDNF in some assays.

Is Dihexa safe?

Reported considerations: no human safety data, theoretical concern: c-Met pro-growth signalling and malignancy. The evidence base is largely preclinical (animal/in-vitro); published randomised human clinical trials are lacking or absent. No human safety data. Theoretical oncogenic concern from pro-growth mechanism. Research compound only. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of Dihexa?

Commonly cited ranges (educational reference, not a recommendation): low research-defined, typical no established human dose (8-20mg anecdotal, unvalidated), high unknown safe ceiling. Administration: oral, subcutaneous, transdermal (anecdotal). Half-life: not well characterised in humans.

Is Dihexa legal in Australia?

Australian status: Not ARTG-registered; research. No human safety data. Theoretical oncogenic concern from pro-growth mechanism. Research compound only. 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 Dihexa?

Reconstitution/storage reference: research-defined (poorly water soluble); storage: refrigerated/frozen.

What is Dihexa commonly stacked with?

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