Dihexa 2.5mg
Potent nootropic — synaptic growth, memory & cognitive repair
Dihexa (N-hexanoic-Tyr-Ile-(6) aminohexanoic amide) is a synthetic peptide derived from angiotensin IV, developed at Washington State University. It is estimated to be 7 orders of magnitude (10,000,000×) more potent than BDNF at promoting synaptogenesis — new synapse formation between neurons. It is the most potent cognitive-enhancing peptide discovered and is used for Alzheimer's, traumatic brain injury, and extreme cognitive optimisation.

How It Works — Mechanism of Action
The precise biology behind this peptide's effects
Dihexa binds to and activates HGF (hepatocyte growth factor) receptor c-Met in the brain, which is distinct from BDNF receptors. c-Met activation triggers a cascade of synaptic growth, dendritic spine formation, and neuronal connectivity. It also potentiates NMDA receptor function, improving glutamate-mediated learning and memory consolidation.
Transdermal cream: Apply to wrist/forearm — absorbed through skin into circulation. Oral capsules: Some absorption but lower bioavailability. Nasal drops: Experimental but potentially high CNS delivery.
Dosage Protocol
GHH physician-guided dosing guidelines
Transdermal: 10–24 mg applied to skin daily. Oral: 10–20 mg daily. Due to extreme potency, less is often more — start at lowest dose and assess cognitive response over 2–4 weeks before increasing.
When to Expect Results
A realistic timeline from first dose to full effect
Initial cognitive changes: 1–2 weeks. Peak synaptogenesis effects: 4–8 weeks. Long-lasting structural brain changes persist weeks after stopping.
Side Effects
What to watch for and how common they are
Not extensively human-studied. Reported: headache, irritability, vivid dreams, social withdrawal at high doses. Start low. Not for recreational or unsupervised use.
Contraindications
Who should not use this peptide
Pregnancy. Active cancer (promotes cellular growth). Bipolar disorder (CNS stimulation). Not combined with other nootropics unsupervised.
